Abstract

PURPOSE:To enable enlargement and reduction with good efficiency by providing a window size varying means and an optimum window arranging means which checks the number and sizes of opened windows and changes the window positions so that their overlaps become minimum. CONSTITUTION:The window size varying means 23 receives the number of a window that the user inputs from the keyboard of a terminal device 1 from a key input control means 22, judges a previously defined window size, and vary the size of the window. Then the optimum window arranging means 21 checks the number and sizes of the windows which are opened when variation information on the window size is received from the window size varying means 23, and changes the window positions so that the overlaps between the windows become minimum. Consequently, the windows are enlarged or reduced in the best arrangement.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window enlargement/reduction method, particularly to a window enlargement/reduction method in a multi-window system used as an input/output device of an information processing system.

[Conventional technology]

Conventionally, this type of window enlargement/reduction method has been carried out in such a way that the user freely enlarges/reduces the size using a mouse, but the window is not automatically rearranged.

[Problem to be solved by the invention]

With the conventional window enlargement/reduction methods described above, it is difficult for inexperienced users to change the window size, and furthermore, the window size cannot be changed quickly. Furthermore, when multiple windows are open at the same time, there is a problem in that enlarging the size of a window often hides other windows.

[Means for Solving the Problems] The window enlargement/reduction method of the present invention is a multi-window system used in an information processing system. expansion/
A window size change means that performs reduction, and when receiving window size change information from this window size change means, checks the number and size of open windows and changes the window position so that window overlap is minimized. and an optimal window placement means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. 1 is a terminal device that performs input/output, and 2 is an information processing system that performs processing based on requests from the terminal device. 22 is a key input control means for accepting a window number entered by the user from the keyboard of the terminal device 1; 23 is a key input control means for determining a predefined window size from the number received from the key input control means 22, and determining the window size; The window size changing means 21 checks the number and size of windows that are open at the time of changing the window size, and tries to avoid hiding other windows as much as possible by changing the window size. This is an optimal window placement means that changes the window position. In addition,
In the present invention, about 4 to 8 window sizes that can be changed in size are defined in advance, and numbers are assigned in order from the smallest to the largest. At this time, the window size to be defined is
Considering the size of the background window, prepare a size that is the same as the background window, such as 1/2 or 1/4. This allows the window to be enlarged/reduced quickly.

2 and 3 are diagrams for explaining the operation of the embodiment shown in FIG. 1. If the operation is explained with reference to FIGS. 2 and 3, FIG. FIG. 3 is an exemplary diagram before changing the . Here there is a first window indicated by Wl and a second window indicated by W2. Here, the first window Wl and the second window W2
This is the same size as , and this size is set as window size 1. At this time, the user opens the first window Wl.
Suppose we want to expand the length of the window to a size defined as window size 2. Therefore, the user places the mouse cursor inside the first window W1 and inputs ``2'' from the key.The window size changing means 23 sets the first window W1 to window size 2 and inputs this information. It is passed to the optimal window arrangement means 21.The optimal window arrangement means 21 selects the currently opened second window W2.
2nd line so that there are no overlaps with the 9 or the overlap 9 is minimized.
window W2 is moved and output is displayed on the terminal device 1. FIG. 3 shows this resultant state. As shown in FIG. 3, the first window Wl is enlarged to the window indicated by W3, and the second window W2 is expanded so that it is not hidden by the window W3. The position is changed from the bottom left to the top right.

〔Effect of the invention〕

As explained above, the present invention provides a window resizing means that defines the size of a window in advance and quickly enlarges/reduces the window by key input from the keyboard, and at the same time hides other windows by enlarging the window. By having an optimal window arrangement means for rearranging windows so as to minimize danger, there is an effect that efficient enlargement/reduction can be achieved.

Claims (1)

[Claims] In a multi-window system used in an information processing system, there is provided a window size changing means for enlarging/reducing the window size in accordance with a key input from a keyboard specifying a predefined window size, and a window size changing means for enlarging/reducing the window size. and an optimal window arrangement means for checking the number and size of open windows and changing the window positions so that window overlap is minimized when receiving change information.
