◆ keyPressEvent()

void TestWidget::keyPressEvent ( QKeyEvent * event )

inlineoverridevirtual

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

A widget must call setFocusPolicy() to accept focus initially and have focus in order to receive a key press event.

If you reimplement this handler, it is very important that you call the base class implementation if you do not act upon the key.

The default implementation closes popup widgets if the user presses the key sequence for QKeySequence::Cancel (typically the Escape key). Otherwise the event is ignored, so that the widget's parent can interpret it.

Note that QKeyEvent starts with isAccepted() == true, so you do not need to call QKeyEvent::accept() - just do not call the base class implementation if you act upon the key.

◆ mouseDoubleClickEvent()

void TestWidget::mouseDoubleClickEvent ( QMouseEvent * event )

inlineoverrideprotectedvirtual

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

The default implementation calls mousePressEvent().

Note: The widget will also receive mouse press and mouse release events in addition to the double click event. And if another widget that overlaps this widget disappears in response to press or release events, then this widget will only receive the double click event. It is up to the developer to ensure that the application interprets these events correctly.

◆ mousePressEvent() [1/2]

void TestWidget::mousePressEvent ( QMouseEvent * event )

inlineoverridevirtual

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.

Here is the call graph for this function:

◆ paintEvent() [1/2]

void TestWidget::paintEvent ( QPaintEvent * event )

inlineoverridevirtual

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:

\list

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

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: 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.
