I have a LARGE PV-Wave application which does NOT use GUI's.
This application is not likely to start using GUI's... its too
big already.
I wish to allow the user to draw/define a box on a standard 1D plot.
Most people place one corner of the box at the point where a mouse
button was pressed, then draw & erase the box as the mouse moves, then
set the second corner then the button is released.
Can anybody think of a way to do this with the CURSOR command?
Is there a way I can draw and undraw my little box edges with XOR
or something? I don't want my little box perimeter updates to erase
or obscure my existing plot.
