I'm developing an application (using the Xaw widgets) that will have a 
user interface somewhat similar to xfig, i.e., a "canvas" where certain 
drawing operations will be performed, and a "control panel" for selecting 
operations.

Currently, the canvas is implemented as a Label widget (because labels
are simple, and their size is easily controllable).  I add an event
handler for the canvas which processes button, motion, enter/leave, and 
exposure events.  The canvas and the control panel are children of a
Form widget.  Basically, a plain window would be sufficient for the
purpose of drawing.

My question is: Is there a better/easier/cleaner way to implement the canvas?
Any advice is welcome -- thanks!
