Abstract
A method to maintain all of the information that is originally displayed in a window on the display screen in an interactive information handling system, as the size of the window is decreased. A plurality of character sets which have different appropriate width and height attributes are stored in the system. When the size of the window is decreased, a stored character set is selected based on the amount that the window is decreased. Characters from the selected set are then substituted for the corresponding text characters originally displayed. Since the selected character set contains proportionally smaller characters no information is lost. The method allows the operator to dynamically vary the window size, after the initial window has been displayed, by operator action, such as by movement of a mouse. Movement of the mouse in a generally horizontal direction with the button in the held position causes the horizontal window size to decrease. The amount of decrease is calculated in real time by monitoring the movement of the mouse and cursor position. A table is stored in memory which lists all of the displayable character sets that are available. Each character set has a width a…
