The DrawingArea is just a pixmap, it doesn't have any children like the Canvas. To erase the line you have to draw it again with a different gc that uses the background color as its foreground. Of course this leads to other problems if the line is on top of anything else you've drawn, etc. > > Thanks again. > > Luigi > > > John Pye wrote: > > Hi, > > > > I don't know if this is the solution but it sounds similar to a problem > > that I had.
