[quote author="TorbenD" date="1360329674"]I can't give you a Qt example programm causing this problem (havent' compiled the examples) but I can you give a small programm that shows the error. it is a autoupdater library for qt based programms, based on the poject "flevor" together with the mentioned small example programm to show the effect.
There are only two disadvantages: It depends on QuaZIP, a Qt wrapper for zLib/minizip. And it suffers the QtWebkit bug described here: http://qt-project.org/forums/viewthread/23571
If you are interested please give me a note and I will send you the files.

Yes sure if it is not too big example and if I can easily see the behavior then yes please let me know how I can get that code.

Same problem. Qt 5.0.1 mingw (official build from downloads), win7 64bit.

只要创建widget,就是一大堆QWindowsNativeInterface::nativeResourceForWindow: 'handle' requested for null window or window without handle.
自带的示例也是一样的.不知道是不是qt5.0.1的问题?
QT5.0.1 win7 32bit ming/vs2010 (official build)都是!Just create widget, that is a lot of "QWindowsNativeInterface::nativeResourceForWindow: 'handle' requested for null window or window without handle."
QT Example has the same problem in QT5.0.1!
QT5.0.1 win7 32bit mingw4.7/vs2010 (official build) -

"Application Example",When you click to "open" or "save",then there will a lot of "QWindowsNativeInterface::nativeResourceForWindow: 'handle' requested for null window or window without handle."
Whether in "debug" or "release",this problem occurs.

Alright, so it seems it is coming up when you are actually trying to show native dialog. Let me try to reproduce it here

Received, thank you very much. Although I do not know how to fix the patch, had to wait for 5.02.
I will continue to learn.
Thanks again. -

Also on Qt5.0.2 commercial, compiled with VS 2012.2 v110_xp 32 bit:
Warning:painting\qbackingstore.cpp (101:void __thiscall QBackingStore::flush(const class QRegion &,class QWindow *,const class QPoint &)) - QBackingStore::flush() called with non-exposed window, behavior is undefined
-
Solved my reporting of "QWindowsNativeInterface::nativeResourceForWindow: ‘handle’ requested for null window or window without handle."
This was was due to one of my DLLs being built by an earlier version of Qt.
Once I rebuilt all of the code used in my project the error messages stopped.
-
thanks, my warnings are slightly different - it complains about non exposed windows...
