BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a button display method according to the present invention will be described with reference to the drawings.
[0014]
FIG. 1 is a block diagram illustrating a computer that performs button display processing based on the button display method according to the present invention. As shown in FIG. 1, the computer 10 includes a CPU 11 for performing an image conversion process, a memory 12 for temporarily storing image data, an image data to be displayed on a button, and a program for a button display process. (Application program). Further, a monitor 14 for displaying image data and an input device 15 such as a keyboard and a mouse used when a user performs an input operation are connected to the computer 10. Note that an auxiliary storage device such as a flexible disk or a CD-R may be used instead of the hard disk 13.
[0015]
The CPU 11 reads out the image data to be displayed on the button from the hard disk based on the program recorded on the hard disk 13 and stores it in the memory 12, resizes the image according to the size of the button, and then executes the GUI control function of the OS. A part is displayed on the button using the derived class described below. The image data before resizing may be image data in jpeg (Joint Photographic Experts Group), bmp (bitmap), or png (Portable Network Graphics) format, and these image data are converted into bmp format image data by the CPU 11. You.
[0016]
FIG. 2 shows a program (application program) for causing a computer to execute a button display process according to the present invention, in which a GUI control function defined by the OS is inherited as a basic class and image data is displayed on a button. Is a block diagram showing a state in which is generated as a derived class.
[0017]
A GUI control function for displaying image data on a button is generally realized by a button control and a picture control. The button control is a GUI control function used to display a state in which the button performs some operation when the button is pressed on the screen. There are two types of buttons, a default push button and a push button, and the default push button is drawn thicker than the bush button. The default push button indicates a push button that is a candidate for selection among a plurality of push buttons.If the candidate for push button changes due to mouse operation or key operation, the button control selects the applicable push button. Perform processing to convert to default push button display. Other button controls perform focus display when the mouse cursor is moved over the button, display of the pressed state of the button when the mouse is clicked, and the like.
[0018]
The picture control is for performing graphic output within a preset display frame, and is for performing drawing processing of lines and characters in buttons, drawing processing of image files, and the like.
[0019]
The CPU 11 generates a derived class α by inheriting the picture control function corresponding to the basic class α according to the program, and again inherits the derived class α and the basic class α ″ including the button control function to obtain the derived class α ″. Generate The derived class α ″ has a function of resizing image data (member functions G and H) in addition to the picture control function and the button control function. In this way, the control function defined by the OS is provided. By generating the derived class α ″ for inheriting and displaying the image data on the button, there is no need to define an instruction corresponding to the control function of the OS in the program.
[0020]
Hereinafter, a process for causing the CPU 11 to display image data on a button using the generated derived class α ″ will be described with reference to flowcharts illustrated in FIGS. 3 to 6.
[0021]
When the program recorded on the hard disk 13 is started by the computer 10, the CPU 11 performs an initial process as shown in FIG. 3 (step S1). In the initial processing, the CPU 11 secures an area of the memory 12 necessary for resizing the image data, and sets a variable value used for the processing. When the initial processing is completed, the CPU 11 performs a button control inheritance processing (step S2). The inheritance of the button control is a process of generating a derived class α ″ having the functions of the picture control and the button control as described above. In the inheritance process of the control, as shown in FIG. After performing a style construction process for setting a style to be displayed (step S101), a drawing button setting is performed by a subclassing process (step S102). The operation setting of the buttons such as the focus display and the display when the button is turned on / off is performed (step S103), and the data used in the message transmission / reception executed in accordance with the button operation (the message setting) is set (message setting). Step S104) After setting the message, the CPU 11 starts the operation. The resources used in the file construction process (step S101) are released, and when a new class (the derived class α ″ in FIG. 2) is created in the button control inheritance process, the basic class and the like (the basic class shown in FIG. 2) are created. Classes α, α ″, derived classes α) are discarded (resource release (step S105), style discarding (step S106)).
[0022]
Thereafter, the CPU 11 shifts to a state of waiting for a mouse / cursor event transmitted from the OS to the CPU 11 (step S3). Here, the mouse / cursor event indicates the operation content / operation state of the mouse determined by the OS when the user performs an input operation (click processing or the like) using the mouse (step S4). Since the OS is provided with a function (20) for judging a mouse / cursor event, even if the CPU 11 does not actively perform the process of judging the state of the mouse / cursor event in the program, the mouse can be transmitted to the OS. By making a cursor event transmission request (step S5), it is possible to know the state of the mouse cursor regardless of the button display process.
[0023]
When mouse / cursor event information is received from the OS (step S6), the CPU 11 determines whether image data (file) to be displayed on the button is selected by the mouse based on the received mouse cursor state. Perform (Step S7). If image data (file) has not been selected, the CPU 11 proceeds to the process shown in step S3.
[0024]
If image data (file) has been selected, the selected image data is read from the hard disk 13 and stored in the memory 12 (step S8).
[0025]
When the previous image data is recorded in the memory 12, the CPU 11 resizes the image size of the previous image data to the size of the upper surface of the button (step S9). The resizing of the screen size is performed by enlarging or reducing the length of the long side in the vertical or horizontal direction to the length of one side of the upper surface of the button while maintaining the aspect ratio of the previous image data.
[0026]
Specifically, the CPU 11 analyzes the header portion of the image data to obtain the vertical and horizontal sizes of the image data recorded in the header portion, and resizes the image data based on the obtained vertical and horizontal sizes. The data is converted into the highest image quality (highest number of colors) that can be displayed on the computer 10.
[0027]
After ending the above-described resizing process (step S9), the CPU 11 performs an effect process (step S10). The effect processing refers to processing for adjusting the resized image. For example, the CPU 11 moves the center of the resized image data so that the center of the image data is positioned at the center of the display range on the upper surface of the button. In addition, the CPU 11 sets the information of the number of stored pallets (the number of colors used) stored in the header part of the image data to the highest image quality (for example, full color or high color) usable by the computer 10. .
[0028]
After the effect processing (step S10), the CPU 11 stores the image data on which the resizing processing has been performed and the effect processing has been performed on the hard disk 13 (step S11). Thereafter, the CPU 11 outputs the image data to the display buffer (memory 12), performs an image display setting process (step S12), and transmits an image drawing request to the OS (step S13). After receiving the reply of the image drawing request (step S14), the CPU 11 determines whether or not the resized image data is present in the display buffer (memory 12) (step S15). If there is no default image, a default image prepared in advance is output to the display buffer (step S16).
[0029]
Thereafter, the CPU 11 performs a button style setting process (step S17). Specifically, as shown in FIG. 5, the CPU 11 obtains information such as GUI menu information, active window status, and control status used in the window (acquisition of main information (step S201)). ), Information of the current cursor and focus (position, control ID, etc.) and button information (focus in, focus out, button on / off) based on the acquired information (cursor state acquisition (step S202), the button state is acquired (step S203). Thereafter, the CPU 11 sets the position of the cursor to be moved next and the control ID (setting of the cursor state (step S204)), and sets the focus and on / off state of the button at the position of the cursor to be moved (button state). The setting (step S205) is performed.
[0030]
After setting the button style (step S17), the CPU 11 performs a button image setting (step S18) process. In the button image setting processing, the CPU 11 initializes a button frame or a display area (view area) output to a display buffer or the like in the background processing as shown in FIG. 6 (clearing the button view ( Step S301)). The CPU 11 obtains the current system color value in consideration of the fact that the system color of the newly displayed button is changed according to the theme of the GUI window and the like, and obtains the default color of the button frame and the button at the time of focus. The control color and the like are designated (color acquisition and setting (step S302)). Thereafter, the CPU 11 sets a hyperlink associated with the button (link setting (step S303)), and sets display settings other than the button (for example, setting of a tooltip sticky note display, setting of a check box, setting of a pop-up menu). Is performed (setting outside the button (step S304)).
[0031]
Thereafter, the CPU 11 determines whether the data to be displayed on the button is text data, an icon, or image data (type determination processing (step S305)). If the data to be displayed on the button is text data or an icon, the CPU 11 performs a normal button drawing process using the button control function of the OS (step S306). Is set using the derived class α ″ to display image data (bitmap data) on the button on which the button is drawn (step S307), and the bitmap is set in the display area (view area) on the button. Then, the CPU 11 draws the state of the button, for example, the state of the button, such as a flat state, a focused state, and a state in which a border line is displayed (step S308). (Step S309), data for displaying the entire drawn button And outputs to the display buffer (step S310).
[0032]
Thereafter, the CPU 11 switches the image data to be displayed on the monitor 14 to the button display data recorded in the display buffer (step S19), thereby displaying the image data of the button on which the image data is displayed on the monitor 14 (step S20). .
[0033]
By performing such processing, the CPU 11 can display image data on a button using the button control function of the OS. For this reason, when displaying buttons, image files other than text data and icons that can be displayed by the button control function of the OS can be freely pasted, and the variety of the GUI expression format can be expanded. In the computer 10, the image data recorded on the hard disk 13 is resized and effect-processed, so that the image data can be transformed into a size suitable for the display area of the button and displayed. Data other than the prescribed image data can be used, and the customization of the buttons can be easily enhanced.
[0034]
Furthermore, since the button display processing is performed by inheriting the button control function of the OS, it is not necessary to design a part corresponding to the button control as a program, so that the development effort of the program can be reduced and the program can be made compact. It becomes possible to.
[0035]
【The invention's effect】
As described above, by using the button display method and the program for the GUI according to the present invention and the computer-readable recording medium on which the program is recorded, the image data can be displayed on the button by using the button control function of the OS. It can be displayed. For this reason, when displaying buttons, image files other than text data and icons that can be displayed by the button control function of the OS can be freely pasted, and the variety of the GUI expression format can be expanded.
[0036]
Further, since the arithmetic processing unit reads the image data recorded in the storage device and converts the image data into a format suitable for display, it is possible to use data other than the image data predefined in the program. Thus, it becomes easy to enhance the customizability of the button.
[0037]
Furthermore, since the button display processing is performed by inheriting the button control function of the OS, it is not necessary to design a part corresponding to the button control as a program, so that the development effort of the program can be reduced and the program can be made compact. It becomes possible to.
