◆ eventFilter()

bool QAxHostWidget::eventFilter	(	QObject *	,
		QEvent *
	)

protectedvirtual

Filters events if this object has been installed as an event filter for the watched object.

In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Example:

class MainWindow : public QMainWindow
{
public:
    MainWindow();
protected:
    bool eventFilter(QObject *obj, QEvent *ev);
private:
    QTextEdit *textEdit;
};
MainWindow::MainWindow()
{
    textEdit = new QTextEdit;
    setCentralWidget(textEdit);
    textEdit->installEventFilter(this);
}
bool MainWindow::eventFilter(QObject *obj, QEvent *event)
{
    if (obj == textEdit) {
        if (event->type() == QEvent::KeyPress) {
            QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event);
            qDebug() << "Ate key press" << keyEvent->key();
            return true;
        } else {
            return false;
        }
    } else {
        // pass the event on to the parent class
        return QMainWindow::eventFilter(obj, event);
    }
}

Notice in the example above that unhandled events are passed to the base class's eventFilter() function, since the base class might have reimplemented eventFilter() for its own internal purposes.

Warning: If you delete the receiver object in this function, be sure to return true. Otherwise, Qt will forward the event to the deleted object and the program might crash.

◆ focusInEvent()

void QAxHostWidget::focusInEvent ( QFocusEvent * event )

protectedvirtual

This event handler can be reimplemented in a subclass to receive keyboard focus events (focus received) for the widget.

The event is passed in the event parameter

A widget normally must setFocusPolicy() to something other than Qt::NoFocus in order to receive focus events. (Note that the application programmer can call setFocus() on any widget, even those that do not normally accept focus.)

The default implementation updates the widget (except for windows that do not specify a focusPolicy()).

◆ paintEvent()

void QAxHostWidget::paintEvent ( QPaintEvent * event )

protectedvirtual

This event handler can be reimplemented in a subclass to receive paint events passed in event.

A paint event is a request to repaint all or part of a widget. It can happen for one of the following reasons:

repaint() or update() was invoked,
the widget was obscured and has now been uncovered, or
many other reasons.

Many widgets can simply repaint their entire surface when asked to, but some slow widgets need to optimize by painting only the requested region: QPaintEvent::region(). This speed optimization does not change the result, as painting is clipped to that region during event processing. QListView and QTableView do this, for example.

Qt also tries to speed up painting by merging multiple paint events into one. When update() is called several times or the window system sends several paint events, Qt merges these events into one event with a larger region (see QRegion::united()). The repaint() function does not permit this optimization, so we suggest using update() whenever possible.

When the paint event occurs, the update region has normally been erased, so you are painting on the widget's background.

The background can be set using setBackgroundRole() and setPalette().

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.

Note for the X11 platform: It is possible to toggle global double buffering by calling qt_x11_set_global_double_buffer(). For example,

...
extern void qt_x11_set_global_double_buffer(bool);
qt_x11_set_global_double_buffer(false);
...

Note: Generally, you should refrain from calling update() or repaint() inside a paintEvent(). For example, calling update() or repaint() on children inside a paintevent() results in undefined behavior; the child may or may not get a paint event.

Warning: If you are using a custom paint engine without Qt's backingstore, Qt::WA_PaintOnScreen must be set. Otherwise, QWidget::paintEngine() will never be called; the backingstore will be used instead.

◆ resizeEvent()

void QAxHostWidget::resizeEvent ( QResizeEvent * )

protectedvirtual

This event handler can be reimplemented in a subclass to receive widget resize events which are passed in the event parameter.

When resizeEvent() is called, the widget already has its new geometry. The old size is accessible through QResizeEvent::oldSize().

The widget will be erased and receive a paint event immediately after processing the resize event. No drawing need be (or should be) done inside this handler.

◆ showEvent()

void QAxHostWidget::showEvent ( QShowEvent * event )

protectedvirtual

This event handler can be reimplemented in a subclass to receive widget show events which are passed in the event parameter.

Non-spontaneous show events are sent to widgets immediately before they are shown. The spontaneous show events of windows are delivered afterwards.

Note: A widget receives spontaneous show and hide events when its mapping status is changed by the window system, e.g. a spontaneous hide event when the user minimizes the window, and a spontaneous show event when the window is restored again. After receiving a spontaneous hide event, a widget is still considered visible in the sense of isVisible().

◆ winEvent()

bool QAxHostWidget::winEvent	(	MSG *	message,
		long *	result
	)

protectedvirtual

This special event handler can be reimplemented in a subclass to receive native Windows events which are passed in the message parameter.

In your reimplementation of this function, if you want to stop the event being handled by Qt, return true and set result to the value that the window procedure should return. If you return false, this native event is passed back to Qt, which translates the event into a Qt event and sends it to the widget.

Warning: This function is not portable.
