Abstract

A client apparatus, which requests a service to a server apparatus and receives a result corresponding to the request, comprises: a receiving section for receiving screen data corresponding to the result and a position of a status bar area in the screen data from the server; a display section for performing a display based on the screen data; and a control section for detecting a change of display contents of the screen data based on the position of the status bar area and the screen data, causing the display section to perform the display except for the status bar area based on the screen data when it is not detected that the display content of the status bar area is changed, and causing the display section to display the status bar area when it is detected that the display content of the status bar area is changed.

Claims

1. A client apparatus, which requests a service to a server apparatus and receives a result corresponding to the request from the server, the client apparatus comprising:

a receiving section for receiving screen data corresponding to the result of the request and a position of a status bar area in the screen data from the server;

a display section for performing a display based on the screen data; and

a control section for detecting a change of display contents of the screen data based on the position of the status bar area and the screen data, causing the display section to perform the display except for the status bar area based on the screen data when it is not detected that the display content of the status bar area is changed, and causing the display section to display the status bar area when it is detected that the display content of the status bar area is changed.

2. The client apparatus according to claim 1, wherein the control section performs non-display of the status bar area displayed on the display section when it is not detected in a predetermined period that the display content of the status bar area is changed.

3. The client apparatus according to claim 1, wherein the control section causes the display section to display a predetermined area of the status bar area.

4. The client apparatus according to claim 1, wherein the control section causes the display section to display the status bar area when it is detected in a predetermined period that the display content of a predetermined area of the screen data except for the status bar area is changed.

5. The client apparatus according to claim 1, wherein the control section causes the display section to display a part of the status bar area the display content of which is changed.

6. The client apparatus according to claim 1, wherein the control section causes the display section to display the status bar area in a predetermined position.

7. The client apparatus according to claim 6, wherein the control section causes the display section to display the status bar area based on a predetermined layout for the status bar area.

8. A computer system, comprising:

a client apparatus according to claim 1; and

a server apparatus including;

a storage section for storing the screen data of a display screen of the server apparatus corresponding to the requested service;

a transmission section for obtaining the position of the status bar area in the screen data and transmitting the position of the status bar area; and

a screen data transmission section for transmitting the screen data to the client apparatus.

9. A computer readable program storage medium which stored a program to be executed by a computer of a client apparatus for requesting a service to a server and receiving a result corresponding to the request from the server, the program comprising:

a receiving step for receiving screen data corresponding to the result of the request and a position of the status bar area in the screen data from the server;

a display step for performing a display based on the screen data on a display section; and

a control step for detecting a change of display contents of the screen data based on the position of the status bar area and the screen data, performing the display except for the status bar area based on the screen data on the display section when it is not detected that the display content of the status bar area is changed, and displaying the status bar area on the display section when it is detected that the display content of the status bar area is changed.

10. A display method to be executed by a computer of a client apparatus for requesting a service to a server and receiving a result corresponding to the request from the server, the method comprising:

a receiving step for receiving screen data corresponding to the result of the request and a position of the status bar area in the screen data from the server;

a display step for performing a display based on the screen data on a display section; and

a control step for detecting a change of display contents of the screen data based on the position of the status bar area and the screen data, performing the display of except for the status bar area based on the screen data on the display section when it is not detected that the display content of the status bar area is changed, and displaying the status bar area on the display section when it is detected that the display content of the status bar area is changed.

11. The display method according to claim 10, wherein the control step performs non-display of the status bar area displayed on the display section when it is not detected in a predetermined period that the display content of the status bar area is changed.

12. The display method according to claim 10, wherein the control step causes the display section to display a predetermined area of the status bar area.

13. The display method according to claim 10, wherein the control step causes the display section to display the status bar area when it is detected in a predetermined period that the display content of a predetermined area of the screen data except for the status bar area is changed.

14. The display method according to any one of claims 10, wherein the control step causes the display section to display a part of the status bar area the display content of which is changed.

15. The display method according to claim 10, wherein the control step causes the display section to display the status bar area in a predetermined position.

16. The display method according to claim 15, wherein the control step causes the display section to display the status bar area based on a predetermined layout for the status bar area.
