It seems to me we need to do more work to get the HWND. By insepcting Qt code, it seems using QApplicationPrivate::getHWNDForWidget() instead of winId() would suffice. 641875 4 145814 hausmann 2012-06-05 14:08:54 -0700 Comment on attachment 145814 Patch Hm no, if we were using QT += widgets in WebCore, then this would not be needed. But we shouldn't use QT += widgets in WebCore, so the question is: Why dos PluginViewWin.cpp need QWidget? I have the feeling that for Qt 5 it's not actually QWidget that's needed but QWindow instead, to make the resolution from the WebView to a HWND. 641953 5 cmarcelo 2012-06-05 15:44:21 -0700 (In reply to comment #3) > By insepcting Qt code, it seems using QApplicationPrivate::getHWNDForWidget() instead of winId() would suffice. Note that getHWNDForWidget() is implemented using the QWidget's QWindow, so we possibly can do the same, getting rid of the QWidget dependency. 641955 6 cmarcelo 2012-06-05 15:44:45 -0700 (In reply to comment #5) > Note that getHWNDForWidget() is implemented using the QWidget's QWindow, so we possibly can do the same, getting rid of the QWidget dependency.
