set rband

set rband num mode x1 y1 x2 y2

Sets the mode and defines the active region for the 'rubber band' widget.

num    - widget number
mode   - may be either box or line
x1     - lowest X point where the widget will be active (in virtual page units)
y1     - lowest Y point where the widget will be active (in virtual page units)
x2     - highest X point where the widget will be active (in virtual page units)
y2     - highest Y point where the widget will be active (in virtual page units)

After executing set rband, rubber bands are defined by executing q pos which freezes the system until the user clicks, drags, and then releases the mouse somewhere within the active rband area. See the q pos reference page for details on the returned information.

Usage Notes

1. In box mode, as the user clicks and drags the mouse in the active rband area a box is drawn with one corner located at the initial click and the opposite corner located at the release point. In line mode, a line is drawn between these two points.
