Hi gregor,
Thanks soo much for your response.... But it will require code change to all
the popups that use a glass panel. And also in future some developer may
forget to fire a Deffered command when the size changes.... So i dont think
its such a good method....
I am working with pure GWT. Basically I am using the glass panels for modal
popups. I set the size of the glass panel as the current view port size just
before dispalying it. Then the popup is dispalyed. Now on the popup, the
user actions causes the size of the popup to change. If the size becomes
larger than the previous view port size then the view port size will
automatically increase, but the glass panel size remains the same which
causes the bottom region of the viewport to be not covered by glass panel.
Please not that this change of size will not cause a window resize event as
the window size is not changed, only the document size got changed. (BTW i
have a windowresize listener on the glass panel so that part is take care
of.)
Hope this explains my problem.
Thanks,
Litty Preeth
