KDE4: evaluate frameWidth in the Qt thread
When opening a document via Java UNO without a running LO instance, one gets the following Qt error messages: CE> QObject: Cannot create children for a parent that is in a different thread. CE> (Parent is Oxygen::WidgetStateEngine(0x8deb878), parent's thread is QThread(0x8d6cf70), current thread is QThread(0xa8fa7fc8) CE> QObject::installEventFilter(): Cannot filter events for objects in a different thread. CE> QObject::installEventFilter(): Cannot filter events for objects in a different thread. CE> QObject::installEventFilter(): Cannot filter events for objects in a different thread. This happens, because the Java UNO call is processed in the first / Qt thread while document loading happens in a second thread. Document loading actually just calls getNativeControlRegion, which should not involve any drawing. But the KDE4 backend does some style processing to get the correct frame width (QWidget::ensurePolished(), which uses GUI based events and need to be processed in the Qt thread.
