Qt signal slots and gmock - Google Groups You didn't declare rxsignal as a slot. You made it a regular public function, hence why it says no slot exists by that name. However, the Qt moc cannot parse the mock macro. So you cannot directly declare MOCK_METHODs as slots. class AbstractMockRx : public QWidget { Q_OBJECT public slots: virtual void rxsignal()=0; }; QWidget Class | Qt Widgets 5.6 In Qt, QMainWindow and the various subclasses of QDialog are the most common window types. Every widget's constructor accepts one or two standard arguments: QWidget *parent = 0 is the parent of the new widget. If it is 0 (the default), the new widget will be a window.

In the private slots section, we declare slots that correspond to menu entries, as well as a mysterious documentWasModified() slot. Finally, in the private section of the class, we have ...

This signal is emitted when the current item is changed. The new current item's index is passed in index, or -1 if there is no current item. Note: Notifier signal for property currentIndex. QWidget *QToolBox:: currentWidget const. Returns a pointer to the current widget, or 0 if there is no such item. See also currentIndex() and setCurrentWidget(). QWidget — Qt for Python Since Qt 4.0, QWidget automatically double-buffers its painting, so there is no need to write double-buffering code in paintEvent() to avoid flicker.
