## 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.
