public slots: - not always works?

AndrzejB

I have

class ConfigDialog : public QDialog
{
    void keyPressEvent(QKeyEvent *event);
    QLineEdit *syntaxPath;
    QLineEdit *themesPath;
    void load(Config *config);
    void save(Config *config);
    Config *configRef;
public slots:
    void browse(QLineEdit *line);
    void applySlot();
    void okSlot();
public:
    ConfigDialog(Config *config, QWidget *parent);
};

and in debug directory not exists moc_configdialog.o/cpp nor configdialog.moc whereas exists moc_codeeditor.cpp,moc_tabwindow.cpp ,codeeditor.moc

connect(btnOk, SIGNAL(clicked()), this, SLOT(okSlot()));

compiled but not works,

connect(btnOk,  &QAbstractButton::clicked, this, [this]{ okSlot(); });

works

You missed adding Q_OBJECT macro in private section of your class

AndrzejB

After adding I have:

undefined reference to `vtable for ConfigDialog'

undefined reference to `ConfigDialog::staticMetaObject'

Is Ok, after deleting debug directory, Thanks it is solved.

Delete the build directory and build the project again
