Description

  The present invention relates to a display control device and a display control program for changing a window display while maintaining a positional relationship between a plurality of windows displayed on a display unit.

  Conventionally, in a display control device such as a PC (Personal Computer), when a plurality of windows (multi-windows) are displayed on the display screen, if one of these windows is deformed or moved, the positional relationship between this window and other windows Has changed. For this reason, the positional relationship between the deformed / moved window and another window may not be suitable.

  In order to eliminate this inconvenience, the following display control apparatus has been proposed. FIG. 12 is a schematic diagram for explaining multi-window display by the conventional first display control apparatus. In the first display control apparatus, when the windows W10, W11, W12, and W13 are displayed as in the display screen 100 shown in (a), the user uses the operation unit to move the window W13 in the direction of the window W11. When dragging, the display positions of the window W11 and the window W13 are switched and displayed as shown in (b) (see, for example, Patent Document 1).

  FIG. 13 is a schematic diagram for explaining multi-window display by the conventional second display control apparatus. In the second display control device, the display position of the child window W21 can be set to a predetermined display position in the parent window W20 (see, for example, Patent Document 2). (A) shows an example of display of the display screen 200 when this setting is made. When the parent window W20 is moved as shown in (b), the child window W21 is moved together with the parent window W20. Therefore, the child window W21 is displayed at a predetermined display position in the parent window W20 even after the parent window W20 is deformed or moved.

With these devices, when the user performs an operation for deforming and moving one of the plurality of windows, the other windows are automatically moved, thereby allowing the user to change the arrangement position of the other windows. The burden of adjustment can be reduced.

  However, in the conventional first display control apparatus, the mutual display position of the windows is merely changed at the fixed window arrangement position. For this reason, the first display control apparatus has a disadvantage that the positional relationship between the windows after the movement of one window cannot be set to the arrangement position desired by the user. Further, in the conventional second display control apparatus, when the display position of the child window is made to follow the deformation / movement of the parent window, the child window is always displayed at a predetermined position in the parent window. For this reason, in the second display control device, as in the first display control device, the positional relationship between the windows after the movement of one window cannot be set to a user-desired arrangement position. .

  Such inconvenience is also noticeable when a plurality of windows displaying contents related to each other are displayed, such as a window display in an equalizer that processes an audio signal. That is, in an equalizer or the like, the frequency spectrum of the sound to be controlled is displayed in the parent window, and a peak level meter or the like indicating the maximum value (dB) of the sound is displayed in the child window. In the equalizer, it is necessary for the user to control the sound quality while monitoring both the frequency spectrum and the peak level of the sound to be controlled. For this reason, if the positional relationship between the parent window and the child window after the movement of the parent window is not the desired positional relationship of the user, it may be difficult for the user to perform work for controlling the sound quality.

  In order to solve the above-described problems, an object of the present invention is to provide a display control apparatus and a display control program that can arrange display positions of a plurality of windows with good operability.

Is possible. As a result, when working mainly using the parent window while looking at both the parent window and the child window (for example, the frequency spectrum of the sound to be analyzed is displayed in the parent window, and the peak of this sound is displayed in the child window. For example, when the level is displayed, the operability for arranging the parent window and the child window in an arbitrary positional relationship of the user can be improved.

  (3) In the display control device, the storage unit stores a display direction and a distance between the first window and the second window as a positional relationship between the first and second windows. To do. According to this configuration, when the first window is deformed / moved, the second window has the first direction so as to maintain the display direction and the distance between the first window and the second window. The window is moved following the deformation / movement of the window.

  (4) In the display control device, the parent window has a substantially rectangular shape, and the display control unit has the first window and the central portion of the second window as the arbitrary positional relationship received by the operation unit. The display direction and the distance between the corner portion of the second window and the corner portion closest to the center portion of the second window are maintained. According to this configuration, when the first window is deformed / moved, the center of the second window and the corner closest to the center of the second window among the corners of the first window The second window is moved following the deformation / movement of the first window so as to maintain the display direction and distance between them.

  (5) In the display control device, when the display control unit moves the second window following the deformation / movement of the first window, there is an area that is not displayed on the display unit in the second window. In this case, the position of the second window is corrected to be displayed on the display unit, and the positional relationship between the first and second windows stored in the storage unit is updated to reflect the correction content. It is characterized by that.

  (6) In the display control device, the display control unit displays a plurality of second windows on the display unit. According to this configuration, the plurality of second windows are moved following the deformation and movement of the first window, and the positional relationship between the first window and the plurality of second windows can be set arbitrarily by the user. The positional relationship can be maintained.

A display control program that, when moved, functions as a display control unit that updates the positional relationship of the first and second windows stored in the storage unit to the positional relationship after the deformation / movement. Characterized in that there.

  According to the above configuration, the display control unit displays the first and second windows on the display unit, and the positional relationship between the first and second windows is stored in the storage unit. When an operation for deforming / moving the first window is received by the operation unit, the display control unit deforms / moves the first window according to the operation received by the operation unit, and responds to the deformation / movement. The second window is moved so as to maintain the positional relationship stored in the storage unit. Thus, when an operation for deforming / moving the first window is received from the user, the second window follows the deformation / movement of the first window without receiving an operation for moving the second window. Is moved.

  On the other hand, when an operation for displaying / moving the second window is accepted by the operation unit, the display control unit deforms or moves the second window according to the operation, and stores the positional relationship after the deformation / movement. Stored in the department. For this reason, the first and second windows stored in the storage unit are received when an operation for deforming and moving the second window is received from the user so that the first and second windows have a desired positional relationship. It is possible to update the positional relationship of the window to an arbitrary positional relationship of the user.

  According to the present invention, when an operation for deforming / moving the first window is received from the user, the first window is allowed to follow the deformation / movement of the first window without receiving an operation for moving the second window. Two windows are moved.

  In addition, the first and second windows stored in the storage unit are received when an operation for deforming and moving the second window is received from the user so that the first and second windows have a positional relationship desired by the user. It becomes possible to update the positional relationship of the window to an arbitrary positional relationship of the user. Thereby, the operability for arranging the first and second windows in an arbitrary positional relationship of the user can be improved.

  Hereinafter, an embodiment in which the present invention is used in the PC 1 will be described with reference to FIGS. The PC 1 is equipped with an equalizer, and is characterized by the display of a plurality of windows that are displayed when the equalizer is activated.

  According to the present invention, when a window set as a main window among a plurality of displayed windows is deformed / moved, the main window has a positional relationship before the deformation / movement. The sub window moves following the deformation / movement, but following the deformation / movement of the window set as the sub window, the main window does not move and the positional relationship between these windows is changed. is there. Here, the main window corresponds to the first window of the present invention, is a window that does not move following the deformation / movement of other windows, and the sub-window corresponds to the second window of the present invention, It is a window that moves following the deformation / movement of the main window.

  In this embodiment, the user can change which of a plurality of displayed windows is set as the main window. However, as an initial setting, the parent window is set as the main window, and the child window is set. Is set in the subwindow. The parent window and the child window display contents that are related to each other, and the parent window is a window for displaying main contents. The child window is a window for displaying contents that assist the contents of the parent window.

It is. If this device outputs a digital sound signal such as an audio device, the digital sound signal is input to the USB 5.

  The HDD 6 stores a control program for operating each part of the PC 1, an application program such as an audio equalizer or an FFT (Fast Fourier Transform) analyzer, and data necessary for executing the program. The FFT analyzer is an application for analyzing the frequency characteristics of the sound indicated by the digital sound signal. The FFT analyzer includes a display control program that causes the CPU 12 to execute multi-window display control processing. The FFT analyzer is mounted on the audio equalizer. By starting up an FFT analyzer or equalizer on the PC 1, it is possible to analyze the frequency characteristics of the digital sound signal input via the Audio I / F 4 or USB 5. The HDD 6 stores a digital sound signal input via the Audio I / F 4 or the USB 4.

  The I / O interface 11 includes a connection terminal (not shown) for inserting the plug of the operation unit 3 and is an interface circuit for inputting an operation signal from the operation unit 3 through the connection terminal (not shown). is there. The I / O interface 11 outputs the input operation signal to the CPU 12, thereby notifying the CPU 12 of an instruction from the user accepted by the operation unit 3. This instruction includes an instruction to start an application, an instruction to deform / move a window (window deformation / movement instruction), an instruction to generate a window (window generation instruction), and the like.

The CPU 12 controls the operation of each part of the apparatus main body 1a described above.
By starting the FFT analyzer, functional units such as an FFT processing execution unit 120, a setting unit 121, and a child window display control unit 123 are provided.

  The FFT processing execution unit 120 performs FFT processing on the digital sound signal stored in the HDD 6 and performs frequency analysis on the sound indicated by the digital sound signal. The FFT processing execution unit 120 generates a spectrum waveform indicating the analysis result. The FFT processing execution unit 120 generates a peak level meter indicating the signal level (dB) of the digital sound signal to be analyzed and a guide screen for guiding the setting of the display position of the spectrum waveform. The FFT processing execution unit 120 displays the generated spectrum waveform in the VRAM 9 so as to be displayed in the window displayed on the display unit 2 by the parent window display control unit 122 or the child window display control unit 123. Write to data. Further, the FFT processing execution unit 120 writes the generated peak meter and guide screen in the display image data so as to be displayed in a window other than the spectrum waveform. Moreover, the FFT process execution part 120 performs the process by execution of a FFT analyzer and a display control program in addition to the process mentioned above.

  In accordance with the operation signal input from the operation unit 3, the setting unit 121 performs any initial setting in which the parent window is a main window and the child window is a sub-window, and any one of a plurality of windows that display contents related to each other. The window setting is changed to change the window to the main window (first window) and the other to the sub-window (second window). Here, the window for displaying the spectrum waveform is the parent window, and other windows such as the window for displaying the peak level are child windows. When the window setting is changed, the setting unit 121 notifies the parent window display control unit 122 and the child window display control unit 123 of the changed content.

  The parent window display control unit 122 reads the image data of the parent window from the HDD 6 and writes it to the display image data on the VRAM 9 with the set display size and display position. The setting of the display size and the display position is an initial setting that is set in advance, and when the change of the setting is input through the operation unit 3 by the user, the display size and the display position are changed.

  When the parent window display control unit 122 receives an operation signal indicating an instruction to deform / move the parent window, the parent window display control unit 122 performs a process of deforming (including changing the size) / moving the parent window (deforming / moving process of the parent window). Execute. Further, the parent window display control unit 122 executes a parent window transformation / movement process when an operation signal indicating an instruction to change the frequency band division number of the spectrum waveform displayed in the parent window is input. That is, the display size of the changed spectrum waveform is changed in the horizontal axis direction, but the parent window display control unit 122 changes the parent window to a display size that can display the changed spectrum waveform. When the parent window display control unit 122 deforms or moves the parent window, the parent window display control unit 122 notifies the child window display control unit 123 of the change.

  The parent window display control unit 122 stores information (parent window position information) indicating the display position of a predetermined position in the parent window in the RAM 8 in the parent window modification / movement process, and this information is transformed into the parent window modification / movement. If there is a move, it is updated. Here, the window is a rectangle (including a square), and the parent window position information indicates, for example, the display position of the corner near the predetermined position in the child window. The predetermined position in the child window is, for example, the central portion in the child window. The center portion is, for example, the position of the center of gravity of the child window, or the position where diagonal lines intersect when the shape is a quadrangle.

  The child window display control unit 123 reads out the child window image data from the HDD 6 and writes it into the display image data on the VRAM 9 in accordance with the display size and display position according to the operation signal input from the operation unit 3 (child window display). Generation process).

  Further, the child window display control unit 123 generates information (child window position information) indicating an arbitrary positional relationship of the user between the parent window and the child window and stores the information in the RAM 8. The child window position information is information indicating a distance and direction between a predetermined position of the parent window indicated by the parent window position information and a predetermined position of the child window. For example, the child window position information indicates the distance on the X coordinate and the Y coordinate between a predetermined position of the parent window and a predetermined position of the child window. The predetermined position of the child window is, for example, the center portion of the child window as described above. The child window position information can be arbitrarily changed by the user, for example, by an operation of moving / deforming the child window selected using the mouse 32.

  When the parent window display control unit 122 is notified of deformation / movement of the parent window, the child window display control unit 123 performs processing for changing the display position of the child window following the deformation / movement of the parent window (parent window). The child window deformation / moving process following the deformation / movement of is performed. In this process, for example, the child window display control unit 123 reads the parent window position information and the child window position information indicated by the parent window position information after the transformation / movement from the RAM 8. The child window display control unit 123 calculates a position away from the display position indicated by the parent window position information in the distance and direction indicated by the child window position information as the display position of the child window (predetermined position). When the child window display control unit 123 moves the child window to the calculated display position, the child window display control unit 123 determines whether the child window has an area that is not displayed on the display screen 21. When the child window display control unit 123 determines that there is an area that is not displayed, the child window display control unit 123 corrects the display position of the child window so that the entire area is displayed on the display screen 21. The child window display control unit 123 moves the child window to the calculated display position or the corrected display position in the display image data on the VRAM 9. As a result, even if the parent window is deformed / moved, the child window display control unit 123 moves the child window to move between the parent window indicated by the child window position information and the child window. Arbitrary positional relationships of users can be maintained.

  When a setting change is notified from the setting unit 121 to the parent window display control unit 122 and the child window display control unit 123, the display control units 122 and 123 are notified of the main window instead of the parent window. For the window, the above processing is executed for the notified subwindow instead of the child window.

  FIG. 2 is a diagram showing an example of the display screen 21 on which the parent window W1 and the child windows W2 and 3 are displayed. In this case, the parent window position information about the child window W2 indicates the display position p1 (coordinates) of the corner. The child window position information for the child window W2 indicates the distance x1 on the X coordinate and the distance y1 on the Y coordinate between the display position p2 at the center and the display position p1 at the corner. The parent window position information for the child window W3 indicates the corner display position p3 (coordinates). Further, the child window position information regarding the child window W3 includes the distance x2 on the X coordinate and the distance y2 (negative value) on the Y coordinate between the display position p4 at the center and the display position p3 at the corner. It is shown.

  FIG. 3 is a diagram illustrating an example of the display screen 21 in which the child windows W2 and W3 are moved following the movement of the parent window W1. Here, on the display screen 21 shown in FIG. 2, the parent window W1 is moved as indicated by the one-dot chain line arrow by executing the above-described deformation / movement of the parent window, and the child window moves following the movement of the parent window. Is displayed. In this case, the parent window position information stored in the RAM 8 is updated to the parent window position information (corner display positions p11, p13) after the deformation / movement of the parent window W1.

  The display positions of the child windows W2 and W3 are calculated by the child window display control unit 123 based on the updated parent window position information and child window position information. For example, for the display position of the child window W2, the distance x1 is added to the X coordinate of the corner display position p11 indicated by the parent window position information, and the distance y1 is added to the Y coordinate to display the center display position p12. Is calculated. As for the display position of the child window W3, the distance x2 is added to the X coordinate of the corner display position p13 indicated by the parent window position information, and the distance y2 (negative value) is added to the Y coordinate. The display position p14 of the part is calculated. Even if the child windows W2 and W3 are displayed at the calculated display position, they do not protrude from the display screen 21, so that the child windows W2 and W3 are moved to the display screen 21 as shown in the figure.

  FIG. 4 is a diagram illustrating an example of the display screen 21 in which the child windows W2 and W3 are moved when the size of the parent window W1 is changed. Here, in the display screen 21 shown in FIG. 2, it is assumed that the parent window W1 is enlarged by executing the deformation / movement process of the parent window. The child windows W2 and W3 are moved and displayed following the change in the display size of the parent window W1. In this case, the position information of the parent window W1 stored in the RAM 8 is updated to the parent window position information (corner display positions p21, p23) after the deformation / movement of the parent window W1.

  The display position p22 at the center of the child window W2 is calculated by adding the distance x1 to the X coordinate of the corner display position p21 indicated by the parent window position information and adding the distance y1 to the Y coordinate. In the display position p24 at the center of the child window W3, the distance x2 is added to the X coordinate of the corner display position p23 indicated by the parent window position information, and the distance y2 (negative value) is added to the Y coordinate. Is calculated. Even if the child windows W2 and W3 are displayed at the calculated display position, they do not protrude from the display screen 21, so that the child windows W2 and W3 are moved to the display screen 21 as shown in the figure.

  FIG. 5 is a diagram showing an example of the display screen 21 on which the display of the child windows W2 and W3 has been corrected. Here, in the display screen 21 shown in FIG. 2, the parent window W <b> 1 has been moved to the corner of the display screen 21. The display positions of the child windows W2 and W3 following the movement are calculated, and it is determined that the display positions of the child windows W2 and W3 protrude from the display screen 21. In this case, the display position is corrected so as to be shifted to the inside of the display screen 21 by the dimension protruding from the display screen 21, and the child windows W2 and W3 are moved to the display screen 21 as shown in the figure. .

  FIG. 6 is a diagram illustrating an example of the display screen 21 in which the display size of the child window W3 is changed. Here, it is assumed that the display size of the child window W3 has been changed on the display screen 21 shown in FIG. In this case, the display position p3 of the nearest corner from the child window W3 whose display size has been changed is acquired as parent window position information. Then, the distance on the X coordinate and the Y coordinate from the display position p44 at the center of the child window W3 to the display position p3 is acquired as child window position information. These pieces of information stored in the RAM 8 are updated with the newly acquired parent window position information and child window position information.

  FIG. 7 is a flowchart showing an example of child window generation processing executed by the PC 1 shown in FIG. This processing is executed when an execution instruction of the FFT analyzer is input to the CPU 12 or when a child window generation instruction is input to the child window display control unit 123.

  First, the child window display control unit 123 executes normal window generation processing such as reading image data of a child window stored in the HHD 6 and storing it in the RAM 8 (S1). Thereafter, when receiving an operation signal indicating an instruction to select a parent window from the user, the setting unit 121 stores window setting change information in the RAM 8 (S2). The window setting change information is information for specifying a window set as the main window among a plurality of windows displayed on the display screen 21.

  When an operation signal for changing the window setting is not received, the parent window is set as the main window as an initial setting, and in this case, step S2 is not executed. The processing shown in FIGS. 7 to 11 will be described below assuming that the window setting has not been changed. When the window setting is changed, in the processing shown in FIGS. 7 to 11, the same processing is executed for the window set as the main window instead of the parent window, and is set as the sub window instead of the child window. The same processing is executed for the opened window.

  Thereafter, the child window display control unit 123 reads child window size information, child window position information, and parent window position information stored in the initialization file of the HDD 6 and stores them in the RAM 8 (S3). When the child window position information and the parent window position information are not stored in the HDD 6, the child window display control unit 123 reads the initial settings of these information stored in the ROM 7. The child window size information indicates the vertical and horizontal sizes of the child window.

  For example, in the example described above with reference to FIG. 2, the display position p1 of the nearest corner of the child window W2 indicated by the X coordinate and the Y coordinate is read as the parent window position information. Further, the distance x1 on the X coordinate and the distance y1 on the Y coordinate between the display position p1 of the nearest corner of the child window and the display position p2 of the center of the child window are read as child window position information.

  The child window display control unit 123 calculates the display position of the child window based on the read child window position information and parent window position information (S4). Specifically, the child window display control unit 123 specifies the display position of the nearest corner of the child window from the parent window position information. Then, the child window display control unit 123 calculates a position away from the nearest corner by the distance indicated by the child window position information.

  For example, in the example described above with reference to FIG. 2, the display position p1 of the nearest corner of the child window W2 is specified, and the distance x1 and the distance y1 are added to the display position p1 to obtain the center position of the child window W2. The display position p2 is calculated.

  Next, the child window display control unit 123 determines whether or not the child window protrudes from the display screen 21 when the child window is displayed at the size indicated by the child window size information and the calculated display position (S5). If it is not determined that the child window protrudes from the display screen 21 (NO in S5), the child window display control unit 123 executes step S7 described later. When it is determined that the child window protrudes from the display screen 21 (YES in S5), the child window display control unit 123 calculates the correction position of the display position of the child window (S6). For example, in the case of the example described above with reference to FIG. 5, it is determined that the child window protrudes from the display screen 21. More specifically, the child window display control unit 123 calculates the correction position from the display position of the child window indicated by the child window display position and the child window size information calculated in step S4. Get the dimensions on the X and Y coordinates of the minute. The child window display control unit 123 calculates a display position obtained by shifting the child window in the X coordinate direction and the Y coordinate direction by the acquired dimension as a correction position.

  The child window display control unit 123 displays the child window on the display unit 2 using the display controller 10 (S7). Specifically, the child window display control unit 123 writes the image data of the child window having the display size indicated by the child window size information into the calculated display position or the corrected display position in the display image data on the VRAM 9. The child window display control unit 123 instructs the display controller 10 to display the display image data on the VRAM 8.

  The child window position information and the parent window position information stored in the HDD 6 are acquired by execution of step S3, and the display position of the child window is obtained from the child window position information and parent window position information acquired by execution of step S4. Is calculated. For this reason, the parent window and the child window are stored in the HDD 6 as parent window position information and child window position information, so that the parent window and child window are separated from each other by an arbitrary distance. And child windows can be displayed.

  When the child window protrudes from the display screen 21 by executing step S6, the display position of the child window is corrected, so that the user can save the trouble of correcting the display position of the child window using the operation unit 3. Therefore, operability can be improved.

  FIG. 8 is an example of a flowchart showing a parent window transformation / movement process executed by the PC 1 shown in FIG. This process is executed, for example, when a parent window deformation / movement instruction is input from the user to the parent window display control unit 122. The parent window display control unit 122 executes normal parent window transformation / movement processing in accordance with the inputted parent window transformation / movement instruction (S21). Specifically, when an instruction to move the parent window is input, the parent window display control unit 122 calculates the display position of the parent window that has been moved in accordance with the instruction to move the parent window. When an instruction to change the size of the parent window is input, the parent window display control unit 122 sets the display position and display size of the parent window whose size has been changed by the amount in accordance with the instruction to change the size of the parent window. calculate.

  The parent window display control unit 122 changes the display image data on the VRAM 9 to the calculated display size and display position, and displays the display image data on the VRAM 9 using the display controller 10. Thereafter, the parent window display control unit 122 updates the parent window position information stored in the RAM 8 to the parent window position information after the display position is changed.

  Next, the parent window display control unit 122 determines whether a child window is being displayed on the display screen 21 (S22). If it is not determined that the child window is displayed on the display screen 21 (NO in S22), the parent window display control unit 122 ends this process. When determining that the child window is displayed on the display screen 21 (YES in S22), the parent window display control unit 122 notifies the child window display control unit 123 of the deformation / movement of the parent window, and thereafter This process is terminated.

  FIG. 9 is an example of a flowchart showing a child window moving process following the parent window deforming / moving process shown in FIG. This process is executed when the child window display control unit 123 is notified of deformation / movement of the parent window from the parent window display control unit 122.

  First, the child window display control unit 123 calculates the display position of the child window (S31). Specifically, the child window display control unit 123 acquires parent window position information and child window position information from the RAM 8. The child window display control unit 123 moves the child window so that the center portion of the child window is positioned at a position separated from the display position of the corner of the parent window indicated by the acquired parent window position information by the distance indicated by the child window position information. The display position of the window is calculated.

  For example, in the example described above with reference to FIG. 3, the distance x1 on the X coordinate and the distance y1 on the Y coordinate are added to the display position p11 of the corner indicated by the parent window position information to display the center portion of the child window. A position p12 is calculated.

  After that, the child window display control unit determines whether or not the child window protrudes from the display screen 21 when the child window is arranged at the child window display position calculated in step S31 (S32). This determination method is the same as that described in step S5 in FIG. If it is not determined that the child window protrudes from the display screen 21 (NO in S32), the child window display control unit 123 executes step S34 described later. On the other hand, when it is determined that the child window protrudes from the display screen 21 (YES in S32), the child window display control unit 123 corrects the display position of the child window (S33). The method for correcting the display position of the child window is the same as that described in step S6 in FIG.

  Thereafter, the child window display control unit 123 moves the child window to the display position calculated in step S31 or the display position corrected in step S33 (S34). Specifically, the child window display control unit 123 changes the position of the child window on the display image data stored in the VRAM 9 to the display position calculated in step S31 or the display position corrected in step S33. The child window display control unit 123 displays the display image data on the VRAM 9 using the display controller 10.

  In step S31, the child window display control unit 123 calculates the display position of the child window in the distance and direction indicated by the child window position information from the display position of the corner of the parent window indicated by the changed parent window position information. . In step S34, the child window is moved to the calculated display position. Therefore, the child window is moved following the deformation / movement of the parent window, and the positional relationship between the parent window and the child window can be maintained at the positional relationship before the change. For this reason, when the display of the parent window is changed, the burden on the user to perform an operation for returning the child window to the positional relationship before the change is reduced, and operability can be improved.

  In the present invention, the positional relationship between the child window and the parent window is automatically adjusted so as to be the positional relationship before the deformation / movement of the parent window. It is possible to improve operability without giving troublesomeness for suitably adjusting the positional relationship, and to effectively prevent the monitoring of the user of both the child window and the parent window by such operation. it can.

  FIG. 10 is a flowchart showing an example of child window deformation / movement processing executed by the PC 1 shown in FIG. FIG. 9 shows the child window moving process following the parent window deforming / moving process, but this flowchart shows the child window single deforming / moving process without the parent window deforming / moving process. . This process is executed when an instruction to change the display of the child window is input from the I / O interface 11 to the child window display control unit 123. The instruction to change the display of the child window includes a child window movement instruction for instructing movement of the child window and a child window size change instruction for instructing change of the child window size. The child window movement instruction is input to the child window display control unit 123 when the user performs an operation of dragging the child window on the display screen 21 with the mouse 32 or the like. The child window size changing process is input to the child window display control unit 123 when the user performs an operation of enlarging or reducing the size of the child window on the display screen 21 with the mouse 32.

  First, the child window display control unit 123 executes normal processing for moving a child window in accordance with the child window movement instruction input from the I / O interface 11 (S41). In this process, when a child window movement instruction is input, the child window display control unit 123 calculates the display position of the child window so that the child window is moved by the distance and direction according to the child window movement instruction. When the child window size change instruction is input, the child window display control unit 123 calculates the display size and the display position of the child window so that the size is changed according to the child window size change instruction. Then, the child window display control unit 123 changes the display position of the child window in the display image data on the VRAM 9 to the calculated display position (in the case of a child window size change instruction, the display position and the display size).

  The child window display control unit 123 displays the display image data on the VRAM 9 using the display controller 10.

  Next, the child window display control unit 123 acquires new parent window position information and child window position information (S42). Specifically, the child window display control unit 123 refers to the VRAM 9 and acquires the display position of each corner of the parent window and the display position of the center of the child window. The child window display control unit 123 specifies the nearest corner of the center of the child window, and acquires the display position of the nearest corner as parent window position information. Then, the child window display control unit 123 acquires the distance and direction between the corner display position indicated by the parent window position information and the center of the child window as child window position information. In the example described above with reference to FIG. 6, the parent window position information indicating the display position p3 of the nearest corner of the display position p44 of the center part of the child window is acquired. Then, the distance x2 on the X coordinate and the distance y3 on the y coordinate between the display position p44 and the display position p3 are acquired as child window position information.

  Thereafter, the child window display control unit 123 stores the acquired child window position information and parent window position information in the RAM 8 (S43).

  When the child window is deformed / moved in step S42, the child window position information stored in the RAM 8 is updated. For this reason, by moving the child window so that it is in an arbitrary positional relationship between the parent window and the user, the user can move the child window between the parent window and the parent window that is retained even when the parent window is deformed or moved. The positional relationship can be any positional relationship of the user.

  FIG. 11 is a flowchart showing an example of a child window display end process executed by the PC 1 shown in FIG. This sub-window display end process is executed when an instruction to end the FFT analyzer is given to the child window display control unit 123 or when an instruction to end the display of the child window is input.

  First, the child window display control unit 123 executes a normal process for ending the display of the child window (S51). Next, the child window display control unit 123 stores the parent window position information and child window position information stored in the RAM 8 in the initialization file on the HDD 6 (S52). Thereafter, the child window display control unit 123 ends this process.

  By executing step S52, the parent window position information and the child window position information are stored in the initialization file. Therefore, when the child window is displayed next time, the current child window is displayed in step S3 shown in FIG. The child window and the parent window are displayed according to the positional relationship at the end. As a result, the positional relationship between the parent window and the child window suitable for the user can be applied to the next display of the child window, and the parent window and the child window are displayed with a favorable positional relationship with good operability. be able to.

  With the above configuration, in this embodiment, when the display of the parent window is changed by the child window display control unit 123, the child window is moved following the change, and the positional relationship between the parent window and the child window is changed. The previous positional relationship can be maintained. Also, by changing the display of the child window, the positional relationship between the parent window and the child window can be updated to an arbitrary positional relationship of the user. For this reason, even when the parent window is deformed or moved, the parent window and the child window are arranged in an arbitrary positional relationship of the user, and the parent window and the child window are displayed in a positional relationship suitable for the user. Operability can be improved.
