PREVIEW SCREEN CONTROL METHOD

PROBLEM TO BE SOLVED: To regularly display a preview screen in front of a download source browser screen, when the download source browser screen and the preview screen are displayed by different processes, by making the download source browser screen into an input exclusive state. SOLUTION: When a file is downloaded from a browser screen 101, an application having screen control function 300 is activated to generate a window for preview screen, and an application for displaying a preview screen is activated to monitor the preview screen at fixed time intervals. When the preview screen is not ended and not made to a dialogue, the screen 101 is made into the input exclusive state, and the preview screen 400 for the download file is set as a slave screen of the screen 101. When the screen 400 is ended, the input exclusive state of the screen 101 is released, and the monitoring of the screen 400 is ended. COPYRIGHT: (C)2009,JPO&INPIT
