Косяк именно с SLOT(setValue(int)). Если же например вот так SLOT(close()) то срабатывает.class testDialog : public QDialog { Q_OBJECT public: explicit testDialog( QWidget* parent=0, Qt::WFlags f=0); public: ~testDialog(); private slots: void testSlot(int value); public: Ui::testDialog* ui Сигналы и слоты в Qt., Ошибка "No such slot" без видимой… } И всё же, при исполнении получаю в потоке ошибок: "Object::connect: No such slot GLFirst::animate()".Кстати, я когда-то читал статью, где создатели Qt подробно объясняли, почему они решили реализовывать систему сигналов- слотов с помощью MOC, а не шаблонов.

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; }; Application Example | Qt Widgets 5.9 The public API is restricted to the constructor. In the protected section, we reimplement QWidget::closeEvent() to detect when the user attempts to close the window, and warn the user about unsaved changes. 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 ...
