I had a confusing problem on Mac with Qt 4.8 and as a side note but it works with 5.2.
If I start the following application I get the "test print" immediately after the start. If I start my test application with "modal" the "test print", comes if I close the window. What is the cause? (Does it creates an own event loop on mac? why does it work on windows and linux?) #include <QWidget> #include <QApplication> #include <QDebug> class TestWidget : public QWidget { Q_OBJECT public: TestWidget() { QMetaObject::invokeMethod(this, "printTest", Qt::QueuedConnection); } public slots: void printTest() { qDebug() << "test print"; } }; int main(int argc, char *argv[]) { QApplication a(argc, argv); TestWidget* myTest = new TestWidget(); if (a.arguments().contains("modal")) myTest->setWindowModality(Qt::WindowModal); myTest->show(); return a.exec(); } #include "main.moc" PS: In the documentation even in Qt 5.x There is some strange comment at WindowModality: "This property only makes sense for windows." <- which is not true, or I am wrong? _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
