Problems solved by technology

However, this method also has problems because it becomes difficult to apply when the number of application programs increases, and a configuration that enables users of the application programs to know the status of other application programs must be redesigned, which causes configuration changes. complicated
[0009] Also, there is no clear description of a technique for preventing other application programs from interfering with the currently used application program in the display of windows in the aforementioned Japanese Patent Application Laid-Open Nos. Hei 5-233195 and 2002-111805

[0050] figure 1 The shown block diagram shows the electrical configuration of the multi-window display device 11 according to the first embodiment of the present invention. The multi-window display device 11 of the first embodiment is, for example, a (not shown) portable cellular phone, and, as figure 1 As shown, a window manager 12 and a display part 13 are included. The window manager 12 responds to window control requests from the application programs AP1, AP2, and AP3 (for example, the overlapping order of the respective windows W1, W2, and W3, the size of the respective windows W1, W2, and W3, changes in display positions, or such requests ), display the respective windows W1, W2 and W3 by overlapping the respective windows W1, W2 and W3 with each other while controlling the display priority of the respective windows W1, W2 and W3 on the display section 13. Particularly in the first embodiment, the window manager 12 is configured to judge whether to allow the executio...

[0064] Figure 6 The shown block diagram shows the electrical configuration of the multi-window display device (11A) according to the second embodiment of the present invention. exist Figure 6 , the same reference numerals are assigned to the figure 1 Parts of the same functions as those in the first embodiment shown are omitted, and therefore descriptions of these parts are omitted. Figure 6 The multi-window display device 11A of the second embodiment shown includes a figure 1 The configuration of window manager 12 shown is different from the configuration of window manager 12A. The window manager 12A judges whether to allow the execution of the display screen from the display part 13 according to the preset display priority of the application program that initially issued the window control request and the function of the "display mode" that is suitable for indicating "whether to display" the window. The window control request of each application program AP1, AP2 and...

Abstract

A multi-window display device is provided which is capable of preventing interference with each other in displaying of two or more windows caused by a window control request from any one of two or more application programs. A window manager judges whether or not a window control request from the application program corresponding to any one of two or more windows being displayed on a display section is allowed to be executed, based on preset display priority of the application program that has made a window control request and, if a result of the judgement shows that the request is allowed to be executed, executes the window control request and preferentially displays the any one of two or more windows and, if the result of the judgement shows that the request is not allowed to be executed, neglects the window control request.

Description

technical field [0001] The present invention relates to a multi-window display device and a multi-window management method used in the multi-window display device, in particular to a method applicable to a display screen such as a portable cellular phone, where the entire display screen is occupied by a certain window A multi-window display device in the case of the multi-window display device, and a multi-window management method used in the multi-window display device. [0002] This application claims priority from Japanese Patent Application No. 2002-327454 filed on November 11, 2002, which is incorporated herein by reference. Background technique [0003] A conventional multi-window display device displaying a screen with multiple windows, such as a personal computer, portable cellular phone, or the like, has a window manager adapted to respond to window control requests from two or more applications, via When controlling the display priority of each window, each window...
