hi dear xformers,
I have made a CAD using xforms and canvas.....
I have a big number of graphics primitive, and i have found a
a problem with redraw all the object drawn into the canvas.
I see that when an expose event is sent to the canvas object the
graphs are re-draw one after another and this is not estetically
beatifull..... has someone suggestions for me to solve this problem,
namely does exist a method that performs as the following:
1.freeze the canvas,
2.redraw all
3.unfreeze it
using xforms library ?
Regards
SM
