hi Rainer
Thanks for citing the error. Yes I corrected it, but still error is not
going. The problem is that, My window is being shown, but without the
header and menus on top.
It is showing only the central part. On header I have MGL as title which I
am using here to get the window handle
HWND id = FindWindow(NULL, L"MGL");
Is it some thing that the title being used for catching the app, will be
lost when fitting on the widget. My title was originally there on the app
MGL, but when I am
using this with the handle and trying to deploy then it is being lost as
the header and also the menu bar menus not coming. It may be losing in 3
steps possibly,
either FindWindow, or QWindow or QWidget is losing it. But I am unable to
identify it.
Only QWindow is it possible to show on a centralwidget ? if so then how.
Can you give me some code snippet.
regards
sujan
