seems it must explicit set the size inside PopupPanel
in section
Using a LayoutPanel without RootLayoutPanel
my PopupPanel encloses a DockLayoutPanel and the DockLayoutPanel has size
setSize("1230px", "720px");
the problem is different computer will have different resolution, so sometime the PopupPanel is too large to see in the client's computer, sometime it is too small to see in another client's computer, any method to resolve it?
the popuppanel is shown as attached (this resolution is just match in my pc, but not in others clients pc).
