Abstract

A display control apparatus determines if an application manager has attribute information compatible with attribute information of a selected application program, and controls the application manager which is determined to have the attribute information compatible with the attribute information of the application program to execute display processing of the application program.

Claims

1. A display control apparatus for controlling a screen display on a display unit, comprising:

a determination unit which determines whether or not a plurality of application managers have attribute information compatible with attribute information of a selected application program; and

a control unit which controls the application manager which is determined by said determination unit to have the attribute information compatible with the attribute information of the application program to execute display processing corresponding to the application program.

2. The apparatus according to claim 1, wherein said control unit controls the application manager to execute display processing of the application program so as to display a screen of the application program at a display resolution according to the application manager.

3. The apparatus according to claim 1, wherein said determination unit executes compatibility determination between the attribute information of the application program and the attribute information of the application manager by determining if at least one of attributes set in the attribute information of the application program is equal to a corresponding attribute set in the attribute information of the application manager.

4. The apparatus according to claim 2, wherein said determination unit executes compatibility determination of attributes respectively set in the attribute information of the application program and the attribute information of the application manager in turn from attributes with higher priorities based on priority information of the attributes set in the attribute information.

5. The apparatus according to claim 1, wherein each of the attribute information of the application program and the attribute information of the application manager includes at least one of an attribute of a display resolution, an attribute of a version, an attribute of a UI component to be used, an attribute of the number of colors, and an attribute of transparent processing.

6. The apparatus according to claim 1, wherein the application manager selects the application program which is to undergo display processing from a plurality of application programs.

7. A display control method for controlling a screen display on a display unit, comprising:

a determination step of determining whether or not a plurality of application managers have attribute information compatible with attribute information of a selected application program; and

a control step of controlling the application manager which is determined in the determination step to have the attribute information compatible with the attribute information of the application program to execute display processing corresponding to the application program.

8. The method according to claim 7, wherein in the control step, the application manager is controlled to execute display processing of the application program so as to display a screen of the application program at a display resolution according to the application manager.

9. The method according to claim 7, wherein the determination step is executed by a first application manager so as to determine if a second application manager has the attribute information, and the control step is executed by the first application manager so as to control the second application manager to execute the display processing.

10. A computer-readable storage medium storing a program for controlling a screen display on a display unit, the program making a computer execute:

a determination step of determining whether or not a plurality of application managers have attribute information compatible with attribute information of a selected application program; and

a control step of controlling the application manager which is determined in the determination step to have the attribute information compatible with the attribute information of the application program to execute display processing corresponding to the application program.

11. The medium according to claim 10, wherein in the control step, the application manager is controlled to execute display processing of the application program so as to display a screen of the application program at a display resolution according to the application manager.

12. The medium according to claim 10, wherein the determination step is executed by a first application manager so as to determine if a second application manager has the attribute information, and the control step is executed by the first application manager so as to control the second application manager to execute the display processing.
