hi i want to know how to control the maximum size of a shell(the main
one in my case).
I currently use this method -->
private Shell sh;
public void controlResized(ControlEvent e) {
Rectangle rt=((Shell) e.widget).getBounds();
if(rt.height>500)
sh.setBounds(rt.x,rt.y, rt.width, 500);
}
However this results in flickering ,
the shell has the setMinimumsize() , but how do i do it to restrict a
window's height on resizing?

ohh sorry
there is a bug entry for this
https://bugs.eclipse.org/bugs/show_bug.cgi?id=74001
its an old one, re opened again,this seems to be a genuine request and i don't know why it took so long..the fix also seems to be simple,which can be done in
LRESULT WM_GETMINMAXINFO (int /*long*/ wParam, int /*long*/ lParam) {
LRESULT result = super.WM_GETMINMAXINFO (wParam, lParam);
if (result != null) return result;
if (minWidth != SWT.DEFAULT || minHeight != SWT.DEFAULT) {
MINMAXINFO info = new MINMAXINFO ();
OS.MoveMemory (info, lParam, MINMAXINFO.sizeof);
if (minWidth != SWT.DEFAULT) info.ptMinTrackSize_x = minWidth;
//CHANGE ADD if (minWidth != SWT.DEFAULT) info.ptMaxTrackSize_x = maxWidth;
if (minHeight != SWT.DEFAULT) info.ptMinTrackSize_y = minHeight;
//CHANGE ADD if (minWidth != SWT.DEFAULT) info.ptMaxTrackSize_y = maxHeight;
OS.MoveMemory (lParam, info, MINMAXINFO.sizeof);
return LRESULT.ZERO;
}
return result;
}
if the fix is urgent you can download the development release of the SWT and merge the related changes to rebuild SWT(may lead to more problems)

thnx for the code .. i'll try it though i'm new to SWT. Meanwhile i
think i'll try to change so that i don't require that functionality and
i really don't want to go into the internals of SWT yet.

thnx for the code :)
merging the changes however seems like an extreme step and since im new to SWT.. i don't want to break anything i can't fix considering it's SWT internals.
