Undefined reference to QWidget::event(QKeyEvent *) in custom classes

[anda_skoa]

Nope, no such method:

#> grep QKeyEvent /usr/include/x86_64-linux-gnu/qt5/QtWidgets/qwidget.h
 
class QKeyEvent;
    virtual void keyPressEvent(QKeyEvent *);
    virtual void keyReleaseEvent(QKeyEvent *);

#> grep QKeyEvent /usr/include/x86_64-linux-gnu/qt5/QtWidgets/qwidget.h

class QKeyEvent;
    virtual void keyPressEvent(QKeyEvent *);
    virtual void keyReleaseEvent(QKeyEvent *);

To copy to clipboard, switch view to plain text mode 

#> grep QKeyEvent /usr/include/qt4/QtGui/qwidget.h                     
 
class QKeyEvent;
    virtual void keyPressEvent(QKeyEvent *);
    virtual void keyReleaseEvent(QKeyEvent *);

#> grep QKeyEvent /usr/include/qt4/QtGui/qwidget.h                     

class QKeyEvent;
    virtual void keyPressEvent(QKeyEvent *);
    virtual void keyReleaseEvent(QKeyEvent *);
