Hi,
I am developing a drawing program under XView. 
I have rubber banding objects. This is how i am going about it.

I am having two GCs and a pixmap and a canvas. While rubber banding (in 
event_proc of canvas) i write the image in both the GCs , one has pixmap as
drawable and other has the canvas has drawable. And in repaint_proc I 
Copy the Pixmap on to Canvas ( XCopyPlane). This works, but i dont like it.
There must be a more elegant way of doign it.. i want to avoid drawing to 
two GCs.

Any pointers are welcome. If someone can point to some pd program which does
something similar , then it would be helpful.

Thanks. Pleas e-mail responses to vijay@gateway.iitb.ernet.in

Vijay
