    bool event(QEvent *event) override;
    virtual void mousePressEvent(QMouseEvent *event);
    virtual void mouseReleaseEvent(QMouseEvent *event);
    virtual void mouseDoubleClickEvent(QMouseEvent *event);
    virtual void mouseMoveEvent(QMouseEvent *event);

    virtual void wheelEvent(QWheelEvent *event);

    virtual void keyPressEvent(QKeyEvent *event);
    virtual void keyReleaseEvent(QKeyEvent *event);
    virtual void focusInEvent(QFocusEvent *event);
    virtual void focusOutEvent(QFocusEvent *event);
    virtual void enterEvent(QEvent *event);
    virtual void leaveEvent(QEvent *event);
    virtual void paintEvent(QPaintEvent *event);
    virtual void moveEvent(QMoveEvent *event);
    virtual void resizeEvent(QResizeEvent *event);
    virtual void closeEvent(QCloseEvent *event);

    virtual void contextMenuEvent(QContextMenuEvent *event);

    virtual void tabletEvent(QTabletEvent *event);

    virtual void actionEvent(QActionEvent *event);

    virtual void dragEnterEvent(QDragEnterEvent *event);
    virtual void dragMoveEvent(QDragMoveEvent *event);
    virtual void dragLeaveEvent(QDragLeaveEvent *event);
    virtual void dropEvent(QDropEvent *event);

    virtual void showEvent(QShowEvent *event);
    virtual void hideEvent(QHideEvent *event);
