◆ mousePressEvent()

void QBalloonTip::mousePressEvent ( QMouseEvent event)
protectedvirtual

This event handler, for event event, can be reimplemented in a subclass to receive mouse press events for the widget.

If you create new widgets in the mousePressEvent() the mouseReleaseEvent() may not end up where you expect, depending on the underlying window system (or X11 window manager), the widgets' location and maybe more.

The default implementation implements the closing of popup widgets when you click outside the window. For other widget types it does nothing.

◆ paintEvent()

void QBalloonTip::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,

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 QBalloonTip::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.

◆ timerEvent()

void QBalloonTip::timerEvent ( QTimerEvent event)
protectedvirtual

This event handler can be reimplemented in a subclass to receive timer events for the object.

QTimer provides a higher-level interface to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.
