Detailed Description▲
Property Documentation▲
exclusivePointGrabber : QObject*▲
This property holds the object that will receive future updates
The exclusive grabber is an object that has chosen to receive all future update events and the release event containing the same point that this event carries.
Setting the exclusivePointGrabber property is a convenience equivalent to:
setExclusiveGrabber(points().first(), exclusiveGrabber);Access functions:
-
*exclusivePointGrabber() const
-
void setExclusivePointGrabber( *exclusiveGrabber)
Member Function Documentation▲
Qt::MouseButton QSinglePointEvent::button() const▲
The returned value is always Qt::NoButton for mouse move events, as well as TabletMove, TabletEnterProximity, and TabletLeaveProximity events.

See also buttons()
Qt::MouseButtons QSinglePointEvent::buttons() const▲
The button state is a combination of Qt::LeftButton, Qt::RightButton, and Qt::MiddleButton using the OR operator.
For mouse move or TabletMove events, this is all buttons that are pressed down.
For mouse press, double click, or TabletPress events, this includes the button that caused the event.
For mouse release or TabletRelease events, this excludes the button that caused the event.

QPointF QSinglePointEvent::globalPosition() const▲
Returns the position of the point in this event on the screen or virtual desktop.
The global position of a mouse pointer is recorded at the time of the event. This is important on asynchronous window systems such as X11; whenever you move your widgets around in response to mouse events, globalPosition() can differ a lot from the current cursor position returned by QCursor::pos().

[override virtual] bool QSinglePointEvent::isBeginEvent() const▲
Returns true if this event represents a button being pressed.
[override virtual] bool QSinglePointEvent::isEndEvent() const▲
Returns true if this event represents a button being released.
[override virtual] bool QSinglePointEvent::isUpdateEvent() const▲
Returns true if this event does not include a change in button state.
QPointF QSinglePointEvent::position() const▲
Returns the position of the point in this event, relative to the widget or item that received the event.
If you move your widgets around in response to mouse events, use globalPosition() instead.
