I really get confused.
in my result page, the hierarchy of widget is DialogBox encloses
TabLayoutPanel encloses FlexTable, the FlexTable has three rows.
in the first row, after I add a SimpleLayoutPanel with setSize("100%",
"360px");
and then encloses the DataGrid inside SimpeLayoutPanel, the DataGrid can
shown now.
But the problem is...SimpleLayoutPanel is also implements
RequiresResize<http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/user/client/ui/RequiresResize.html>,
so why can I just use "100%" but not an exact "px" unit?
The TabLayoutPanel has an explicit size in unit of px, then the FlexTable
has setWidth("100%"), is this the cause so I can use just % in the
enclosing SimpeLayoutPanel?
Also, I see DialogBox has not implements
RequiresResize<http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/user/client/ui/RequiresResize.html>and
ProvideResizes, so if the outer browser windows shrink, the DialogBox
will not resize accordingly, this is expected, right?
