Hi again,

I need to draw a vertical line on a canvas, to be used as a cursor

The only graphics trick I know is to draw the line by XOR'ing it
with the canvas and again a second time to erase it.  (That's to
avoid redrawing the whole screen with every move of the cursor.)

Is there a way to do that with gtk-perl?

Can you be more specific on what you want to action to be? Do you
want to draw a line, then drag it with the mouse, and/or move
it with the arrow keys?

It ought to be pretty simple.

Thanks for another wonderful reply.  If the timestamps on your messages
are correct, you took 9 minutes to come up with that code.  Please tell
me you cut and pasted it from somewhere ;o)

I'll need to study your code for a while before I understand it, but I
can tell already that it will be close to what I need, anyway.

I'm off to study it now, and meanwhile thank you!
