To subscribers of the xforms list from "Wei-Cheng (Leon) Wang" <wangwei@minna.cns.iit.edu> :


Last time I posted a message regarding how to detect the resize and
expose event of a form window. It seems there is no people got this
trouble as I got. So, today, hope I am lucky to get some suggestions.

I creates a form and has a canvas on top it. Then I registered expose and
event handlers to the canvas. They are very simple and just print
expose and resize messages respectively. Most of time, the application
can detect both events. But,while I resizes the window, there are almost
15% chances the resize handler did not print out resize message. This
means my application can not trust the registered event handlers. Can some
smart people help me to figure out what is wrong with it ??
