Abstract

PURPOSE:To efficiently perform a processing using a window by displaying the window based on output from a window information storage means to store the shape and display position of each window and that from a superposition sequence storage means to store the superposition sequence of the window. CONSTITUTION:The window display device is comprised of a position input means 1, the superposition sequence storage means 2 which stores the superposition sequence of the window, a superposition sequence change means 3 which changes the content of the superposition sequence storage means 2 with the output from the position input means 1, the window information storage means 4 which stores the shape and display position of each window, and a superposition state information display means 5 which displays the superposition state information of the window with the output from the position input means 1, the superposition sequence storage means 2, and the window information storage means 4. When position information on the display of the superposition state information is inputted from the position input means 1, the superposition sequence of the window having a frame line nearest to the position is changed to a first rank with the superposition sequence change means 3. In such a way, it is possible to easily display the window not being displayed on a screen extending over an entire plane without changing the superposition sequence of another window.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window display device that displays a plurality of windows in a superimposed manner on a screen such as a CRT display. [Prior Art] In a multi-window system that displays multiple windows in a superimposed manner on a screen such as a CRT display, the windows are displayed in a superimposed manner by assigning a superimposition order to the windows and superimposing them in order starting from the lowest one. There is.

To change the superimposition order, a method is adopted in which a target window is specified and it is placed at the top of the list.

The target window is identified by specifying a point within the display area of the target window on the screen using a position input means. However, a window with a low superimposition order may be hidden by other windows and may not be displayed on the screen at all. Displaying such windows on the screen is performed by repeatedly moving the window with the lowest superimposition order to the top. For example, if the superimposition order is [1 2 3 4 5] in descending order and window 4 is not displayed on the screen, window 4
To display on the screen, first set window 5 to the top ([51234]), then set window 4 to the top ([45123]).

[Problem to be solved by the invention]

In this method, if the desired window is not at the lowest level, multiple operations are required to display it on the screen. For example, in the above example, in order to display window 1 on the screen, at least two operations and at most four operations are required. Furthermore, if you do not want to change the superimposition order of windows other than the desired one, a very complicated operation is required.

[Means to solve the problem]

The window display device of the present invention includes a position input means, a window information storage means for storing the shape and display position of each window, a superposition order storage means for storing the order of superimposition of windows, and an output from the position input means. Superimposition order changing means for changing the contents of the superimposition order storage means; Superposition state information display means for displaying window superimposition state information based on the output of the position input means and the outputs from the window information storage means and the superposition order storage means. and window display means for displaying a window based on the output of the window information storage means and the output from the superimposition order storage means.

〔Example〕

The present invention will be explained below with reference to the drawings. FIG. 1 shows a functional block diagram of an embodiment of the present invention. In the figure, 1 is a position input means, and 2 is a superimposition order storage means for storing the superimposition order of windows. Reference numeral 3 denotes a superimposition order changing means for changing the contents of the superimposition order storage means 2 based on the output from the position input means 1.

4 is a window information storage means for storing the shape and display position of each window. Reference numeral 5 denotes superimposition state information display means for displaying window superimposition state information based on the output of the position input means 1, the output from the superimposition order storage means 2, and the output from the window information storage means 4. Reference numeral 6 denotes a window display means for displaying a window on the display device 7 based on the output from the superimposition order storage means 2 and the output from the window information storage means 4.

FIG. 3 shows an example of the stored contents of the superimposition order storage means 2 when the screen state of the display device 7 is as shown in FIG. 2.
An example of the contents stored in the window information storage means 4 is shown in FIG. In FIG. 3, window numbers are held as superimposition order information in descending order of superimposition order. In FIG. 4, the window shape is assumed to be a polygon, and the coordinate values of each vertex are stored counterclockwise. In this example, windows 6, 7, and 8 are hidden behind other windows and are not displayed on the screen at all.

In the above example, FIG. 5 shows an example of display of the superimposed state information by the superimposed state information display means 5 when the superimposed state information display instruction signal is input from the position input means 1. In the figure, the screen of the display device 7 overlaps the window that is displayed in the foreground at the position input from the position input means 1, and the window that is not displayed at all on the screen is marked with a frame different from that of a normal window. is displayed.

When the position information on the superimposition state information display is input from the position input means 1, the superposition order changing means 3 changes the superposition order of the window having the frame line closest to the position to the first position. For example, when the position of 10 is input in FIG. 5, the contents of the superimposition ranking storage means 2 are changed as shown in FIG. 6. As a result, the display state of the screen is changed as shown in FIG.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to easily display a window that is not displayed on the screen in full without changing the superimposition order of other windows, so that processing using windows can be performed efficiently. can.
