Adding widgets to a viewer [message #452339]

My application needs to add canvases to the viewer based on mouse events.
However,
these canvases are not visible in the view until the view is manually
resized. I have tried
calling update(), redraw() on both the canvas and the parent widget with no
luck.

What do I need to do so that the canvases become visible as soon as they are
added?

Thanks,

Jai
