Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a window display system, and more particularly to control of a plurality of windows or icons whose display order is fixed.
[0002]
[Prior art]
An information processing apparatus system having a GUI (GRAPHICAL USER INTERFACE) system that has a single display screen, opens a plurality of windows in the screen, and operates each window by a cursor instruction such as a mouse has been generalized. ing.
[0003]
In these systems, a plurality of windows opened in the display unit have various display areas and display positions. Accordingly, a certain window and another window may be displayed side by side on the display unit, or may be displayed while partly overlapping each other.
[0004]
FIG. 6 shows a case in which two windows (91, 92) are partially overlapped and displayed on the display unit 9, and the current state is when the display order of the window A91 is higher than the display order of the window B92. It is.
[0005]
By operating the mouse 1, the cursor 1K is moved. When the work target is the window A91, since the entire area of the window is displayed, there is no inconvenience in pointing an arbitrary place in the area with the cursor 1K.
[0006]
On the other hand, when the operation target is the window B92, when the cursor 1K enters the area of the window B92, a system utility (not shown) that detects the coordinates of the cursor changes the window display order, and the window B92 is displayed. Is displayed on the front side, and the entire area of the window B92 can be designated by the cursor 1K.
[0007]
As described above, the display order is set in each window. However, a certain kind of window (information display window, for example, a clock display window, an icon, etc.) has a fixed display order and a display position. In the case of overlapping, the top one is always displayed in front of the display unit 9 according to the order.
[0008]
[Problems to be solved by the invention]
FIG. 6 is a window system display state diagram. For example, if the window A91 is this type of window, even if the cursor 1K enters the area of the window B92, the display order does not change. Therefore, in this display state, since it is impossible to instruct the operation of the area position hidden by the window A91 of the window B92, when the operation instruction is given to the window B92, the window A91 is displayed in advance at the current display position. It is necessary to move to a position that does not get in the way.
[0009]
That is, the cursor 1K is dragged with the toolbar 91T of the window A91 to move the window A91 to, for example, the lower right corner of the display unit 9, and the window B92 is similarly dragged to the left.
[0010]
At this time, when the display area of the window A91 is large, the entire area of the window B92 cannot be displayed only by the above-described movement amount, and the window B92 is always partially hidden under the window A91. Therefore, every time it is necessary to instruct the location B where the operation instruction position is hidden under the window A91, the window A91 has to be dragged and moved, which makes the operation complicated.
[0011]
In addition, when there are a plurality of windows whose display order is fixed, unless all of the plurality of windows are moved, an operation instruction to the window to be operated cannot be performed, and there is a problem that the operation becomes more complicated.
[0012]
The present invention is an invention created in view of the above points, and means for leaving a window having a display order higher than that of the work target window from the cursor position so as not to obstruct the cursor instruction to the work target window. The purpose is to provide.
[0013]
[Means for Solving the Problems]
The above-described problems are solved by the present invention configured as follows.
FIG. 1 is a principle block diagram according to claim 1 of the present invention.
[0014]
A display unit 9 in which a plurality of windows are set in display order, a position specifying unit 100 for operating a cursor moving on the display unit 9, a window information area 700 for holding display attributes of the windows, The position of the cursor operated by the position specifying means 100 is input, and the determining means 400 for determining the positional relationship between the cursor position and the display area of the display window based on the information from the window information area 700, and the determining means The moving unit 500 is configured to move the display window away from the current position of the cursor according to the determination result 400.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.
FIG. 2 is a functional block configuration diagram according to the embodiment of the present invention.
[0016]
In the figure, 1 is a mouse for operating a cursor 1K (FIG. 6) that moves on the screen of the display unit 9, and 2 is an input control unit that transmits the operation of the mouse 1 to move the cursor 1K on the screen. Coordinate values are output while moving.
[0017]
Reference numeral 3 denotes a cursor coordinate reading unit, and reference numeral 4 denotes a window determination unit that receives a cursor coordinate value and a window attribute from a window control unit described later and outputs a determination result to a movement processing unit described later.
[0018]
Reference numeral 5 denotes a movement processing unit that moves a window in accordance with an instruction from the window determination unit 4, and reference numeral 6 denotes a window control unit. The window determination unit 4 reads a window attribute value read from the memory 7, The window is displayed on the display unit 9 while updating the window attribute value of the memory 7 according to the instruction.
[0019]
Reference numeral 10 denotes a timer, which sets the weight of the window moving step in the movement processing unit 5. Reference numeral 7 denotes a memory, and each window attribute value is set as a table 8.
[0020]
81 is the window identification code (ID), 82 is the window drawing origin (upper left coordinates), 83 is the width (W) and height (H) of the exclusive area of the window, 84 is the drawing color, The display order on the display unit 9 is set in 85, and a flag indicating that the setting of the display order is fixed is set on or off in 86.
[0021]
The operation of the embodiment of the present invention having the above configuration will be described.
FIG. 3 is a movement determination flowchart for explaining the processing of the window determination unit 4.
[0022]
Step S1: When the system is activated, it waits for input of an event (such as movement of a cursor by mouse operation or clicking of a mouse button). The input control unit 2 counts and outputs the coordinate value of the current position on the display unit 9 of the cursor 1K according to the operation of the mouse 1. Since the coordinate value fluctuates when the cursor 1K moves, the cursor coordinate reading unit 3 outputs the coordinate value of the cursor when moved.
[0023]
Step S2: The window determination unit 4 accesses the memory 7 through the window control unit 6, registers the current active (displayed) window in the table 8, and displays the coordinate value 82 (X, Y) and the exclusive area 83 ( H, W) to verify whether the current coordinates of the cursor 1K have entered the display area of the display window.
[0024]
Step S3: When the window into which the cursor 1K enters is detected, the display order 85 and the flag 86 are further checked. If the flag 86 of the window is off, the display order of the window is updated to the highest display order of the window set with a variable display order, and the screen is rewritten according to the display order by window control. .
[0025]
Step S4: On the other hand, if the flag 86 of the window is on, the movement processing unit 5 is requested to perform processing as a movement target window.
Next, FIG. 4 is a movement process flowchart for explaining the movement process in step S4.
[0026]
Step S10: It is confirmed whether or not a default condition is set for the movement destination.
Step S11: When the movement destination is designated and, for example, it is in the upper right corner as shown in FIG. 5, the coordinates (X = 1024, Y = 0) of the position are set.
[0027]
Step S12: If the movement destination is not specified, the farthest position (for example, the upper right corner of FIG. 5) from the current window display position (X0, Y0) is searched, and the coordinates of the position (X = 1024, Y = 0) is set.
[0028]
Step S13: The number of movements and the movement speed setting will be described with reference to FIG.
Now, the display range where the coordinates (X, Y) of the display unit is the origin (0, 0) at the upper left corner is (X = 0 to 1024, Y = 0 to 768), and the current position of the moving window 910 is (X0 , Y0), where width = W and height = H. Therefore, the movement distance is ΔX = (1024−W) −X0, ΔY = Y0, and the movement distance is moved along the broken line with arrows shown in FIG.
[0029]
The number of movements may be about 10 to 15 frames per second so as not to give a sense of incongruity to the human visual sense. However, in the case of FIG. 5, the description is simplified. The number of movements is 8, and the window 912 is moved at low speed up to 2 times (weight by timer = 3), the window 916 is moved up to 6 times (weight by timer = 1), and the window 918 is moved at low speed up to 8 times. Set (wait by timer = 3).
[0030]
First, a known straight line equation passing through two points (X0, Y0) and (X8, Y8) is set. The above two points are divided into eight, and the coordinates (X1, Y1), (X2, Y2)... (X8, Y8) of each movement point are obtained from the movement distance for each time, and the movement destination coordinates are not shown. And paired with the above-mentioned wait time. Since the coordinate value of the display unit 9 is a positive integer, the moving coordinate value (real number) calculated from a known straight line equation is rounded to a positive integer.
[0031]
Step S14: The position coordinates (X0, Y0) of the current window 910 are saved in an area (not shown) of the table 8.
Step S15: A table in which the distance and weight of each time are set as a pair is sequentially read, and the window is moved one step at a time for a total of eight times.
[0032]
Step S16: Since the fixed window leaves from the work window position until the above step, an operation instruction to the work window is given, and when the operation is completed, the cursor 1K is moved away from the previous window position. If the detachment of the cursor 1K is detected, the saved coordinates are read and the window 910 is restored and drawn again.
[0033]
As for the movement of the window, the movement speed is changed in the above embodiment, but if it does not impair the visual sensation or operability, the multiple divisions are moved at a constant speed, or instantaneously moved to the final position. It may be moved, or if the approach of the cursor is detected at a minute distance, the distance can be controlled to move away from the cursor. In addition to the movement, the evacuation method can be reduced at the position or converted into an icon.
[0034]
Further, when the work is completed, the moving window is returned to the original position, but this is not always necessary, and the moving window may be stopped at the moving destination.
Furthermore, when another window (fixed display order) is already displayed at the destination, another destination may be examined.
[0035]
【The invention's effect】
As described above, according to the present invention, when a plurality of windows are displayed in a superimposed manner, an operation instruction is given to a window that is behind a window that is always displayed in front of an information window or the like. In this case, the information window or the like is automatically detached in accordance with the approach of the cursor for instructing the operation, so that the operation on the work window is facilitated, and the user's work efficiency is greatly improved.
