◆ event()

bool QSystemTrayIconSys::event ( QEvent * event )

protectedvirtual

This is the main event handler; it handles event event.

You can reimplement this function in a subclass, but we recommend using one of the specialized event handlers instead.

Key press and release events are treated differently from other events. event() checks for Tab and Shift+Tab and tries to move the focus appropriately. If there is no widget to move the focus to (or the key press is not Tab or Shift+Tab), event() calls keyPressEvent().

Mouse and tablet event handling is also slightly special: only when the widget is enabled , event() will call the specialized handlers such as mousePressEvent(); otherwise it will discard the event.

This function returns true if the event was recognized, otherwise it returns false. If the recognized event was accepted (see QEvent::accepted ), any further processing such as event propagation to the parent widget stops.

See also: closeEvent(), focusInEvent(), focusOutEvent(), enterEvent(), keyPressEvent(), keyReleaseEvent(), leaveEvent(), mouseDoubleClickEvent(), mouseMoveEvent(), mousePressEvent(), mouseReleaseEvent(), moveEvent(), paintEvent(), resizeEvent(), QObject::event(), QObject::timerEvent()

◆ mouseDoubleClickEvent()

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

The default implementation generates a normal mouse press event.

Note: The widget will also receive mouse press and mouse release events in addition to the double click event. It is up to the developer to ensure that the application interprets these events correctly.

◆ mousePressEvent()

void QSystemTrayIconSys::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 QSystemTrayIconSys::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 QSystemTrayIconSys::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.

If you reimplement this handler, it is very important that you ignore() the event if you do not handle it, so that the widget's parent can interpret it.

The default implementation ignores the event.

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.
