<p>PROBLEM TO BE SOLVED: To easily set screen division through single-time operation by determining vertex coordinates of a window on the basis of the left upper coordinates of the entire screen and dividing the screen in response to a screen division instruction. SOLUTION: When a computer is turned ON, an initial screen appears. To divide the left side in this state, a left-side division icon 1 in a title bar 11 is clicked. Then the CPU senses the left-side division icon 1 being clicked, finds the lateral and longitudinal sizes of the entire screen, and sets the right- side X coordinates of the window to a lateral half of the entire screen, thereby setting the vertex coordinates of the window. Then a left-side divided screen is obtained. When a right-side division icon 2 is clicked, the CPU senses the right-side division screen button being clicked, finds the lateral and longitudinal sizes of the entire screen, and sets the left-side X coordinates of the window to a lateral half of the entire screen, thereby setting the vertex coordinates of the window.</p> |
