Abstract

A multi-window display device is provided which is capable of preventing interference in displaying of 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.

Claims

1. A multi-window display device comprising:

a display device;

a window manager to display, in response to a window control request from any one of two and more application programs, each of which corresponds to any one of two or more windows in a one-to-one relationship, said two or more windows on said display device by having said two or more windows overlap one another while controlling display priority of each of said two or more windows; and

wherein said window manager judges whether a window control request from the application program corresponding to any one of said two or more windows being displayed is allowed to be executed or not, based on preset display priority of the application program that has made said window control request and, if a result of the judgement shows that said window control request is allowed to be executed, executes said window control request and preferentially displays said any one of said two or more windows and, if said result of said judgement shows that said window control request is not allowed to be executed, neglects said window control request.

2. The multi-window display device according to claim 1, wherein said window manager comprises:

an application information managing section to manage display priority of each of said application programs and each of said two or more windows;

a window state managing section to mange a present state of overlapping of each of said two or more windows in a display screen of said display device;

a request judging section judges, based on said display priority managed by said application information managing section and on a present state of overlapping of each of said two or more windows being managed by said window state managing section, whether or not said window control request from said application program is allowed to be executed; and

a window control section controls each of said two or more windows on said display screen of said display device based on said result of said judgement.

3. The multi-window display device according to claim 2, wherein said request judging section, when said display priority of said application program that has made said window control request is higher than that of a window being displayed in a highest location on said display screen of said display device, produces a result from said judgement that said window control request is allowed to be executed and when said display priority of said application program that has made said window control request is lower than that of said window being displayed in a highest location on said display screen of said display device, produces a result from said judgement that said window control request is not allowed to be executed.

4. A multi-window display device comprising:

a display device;

a window manager to display, in response to a window control request from any one of two and more application programs, each of which corresponds to any one of two or more windows in a one-to-one relationship, said two or more windows on said display device by having said two or more windows overlap one another while controlling display priority of each of said two or more windows; and

wherein said window manager judges whether or not a window control request from the application program corresponding to any one of said two or more windows being displayed is allowed to be executed, based on preset display priority of the application program that has made said window control request, and on a function of a display mode to instruct a window to be displayed or not to be displayed and, if a result of the judgement shows that said window control request is allowed to be executed, executes said window control request and preferentially displays said any one of said two or more windows and, if a result of said judgement shows that said window control request is not allowed to be executed, neglects said window control request.

5. The multi-window display device according to claim 4, wherein said window manager comprises:

an application information managing section to manage display priority of each of said application programs and each of said two or more windows;

a window state managing section to mange a present state of overlapping of each of said two or more windows on a display screen of said display device and said display mode;

a request judging section judges, based on said display priority being managed, a present state of overlapping of each of said two or more windows being managed, and said display mode being managed, whether or not said window control request from said application program is allowed to be executed; and

a window control section controls each of said two or more windows on said display screen of said display device based on said result of said judgement.

6. The multi-window display device according to claim 5, wherein said request judging section, when said display priority of said application program that has made said window control request is higher than that of a window being displayed in a highest location on said display screen of said display device and a function of said display mode instructs a window to be displayed, produces a result from said judgement that said window control request is allowed to be executed and when said display priority of said application program that has made said window control request is lower than that of said window being displayed in a highest location on said display screen of said display device or said function of said display mode instructs said window not to be displayed, produces a result from said judgement that said window control request is not allowed to be executed.

7. A multi-window managing method being used in a multi-window display device having a display device and a window manager to display, in response to a window control request from any one of two and more application programs, each of which corresponds to any one of two or more windows in a one-to-one relationship, said two or more windows on said display device by having said two or more windows overlap one another while controlling display priority of each of said two or more windows, for managing a state of overlapping of each of said two or more windows, said multi-window managing method comprising;

a step of judging whether a window control request from the application program corresponding to any one of said two or more windows being displayed on said display device is allowed to be executed or not, based on preset display priority of the application program that has made said window control request and, if a result of the judgement shows that said window control request is allowed to be executed, executing said window control request and preferentially displaying said any one of said two or more windows and, if said result of said judgement shows that said window control request is not allowed to be executed, neglecting said window control request.

8. A multi-window managing method being used in a multi-window display device having a display device and a window manager to display, in response to a window control request from any one of two and more application programs, each of which corresponds to any one of two or more windows in a one-to-one relationship, said two or more windows on said display device by having said two or more windows overlap one another while controlling display priority of each of said two or more windows, for managing a state of overlapping of each of said two or more windows, said multi-window managing method comprising;

a step of judging whether or not a window control request from the application program corresponding to any one of said two or more windows being displayed on a screen of said display section is allowed to be executed, based on preset display priority of the application program that has made said window control request and on a function of a display mode to instruct a window to be displayed or not to be displayed and, if a result of the judgement shows that said window control request is allowed to be executed, executing said window control request and preferentially displaying said any one of said two or more windows and, if a result of said judgement shows that said window control request is not allowed to be executed, neglecting said window control request.

9. A display control program to have a computer achieve a multi-window managing method being used in a multi-window display device having a display device and a window manager to display, in response to a window control request from any one of two and more application programs, each of which corresponds to any one of two or more windows in a one-to-one relationship, said two or more windows on said display device by having said two or more windows overlap one another while controlling display priority of each of said two or more windows, for managing a state of overlapping of each of said two or more windows, said multi-window managing method comprising;

a step of judging whether a window control request from the application program corresponding to any one of said two or more windows being displayed on said display device is allowed to be executed or not, based on preset display priority of the application program that has made said window control request and, if a result of the judgement shows that said window control request is allowed to be executed, executing said window control request and preferentially displaying said any one of said two or more windows and, if said result of said judgement shows that said window control request is not allowed to be executed, neglecting said window control request.

10. A display control program to have a computer achieve a multi-window managing method being used in a multi-window display device having a display device and a window manager to display, in response to a window control request from any one of two and more application programs, each of which corresponds to any one of two or more windows in a one-to-one relationship, said two or more windows on said display device by having said two or more windows overlap one another while controlling display priority of each of said two or more windows, for managing a state of overlapping of each of said two or more windows, said multi-window managing method comprising;
