DESCRIPTION
The QMouseEvent class contains parameters that describe a mouse event.

Mouse events occur when a mouse button is pressed or released inside a widget, or when the mouse cursor is moved.

Mouse move events will only occur when some mouse button is pressed down, unless mouse tracking has been enabled.

Qt makes an automatic mouse grab when a mouse button is pressed inside a widget, and the widget will continue to receive mouse events until the last mouse button is released.

The QWidget::setEnable() function can be used to enable or disable mouse and keyboard events for a widget.

The QCursor widget has static functions for reading and setting the position of the mouse cursor.

The event handlers QWidget::mousePressEvent(), QWidget::mouseReleaseEvent(), QWidget::mouseDoubleClickEvent() and QWidget::mouseMoveEvent() receive mouse events.

See also: QWidget::setMouseTracking() and QWidget::grabMouse().

MEMBER FUNCTION DOCUMENTATION

QMouseEvent::QMouseEvent ( int type, const QPoint & pos, int button, int state )
Constructs a mouse event object.

The type parameter must be Event_MouseButtonPress, Event_MouseButtonRelease, Event_MouseButtonDblClick or Event_MouseMove.

int QMouseEvent::button () const
Returns the button that caused the event.

Possible return values are LeftButton, RightButton, MidButton and NoButton.

Note that the returned value is always NoButton (0) for mouse move events.

See also: state().

Examples: dclock/dclock.cpp movies/main.cpp widgets/widgets.cpp

const QPoint & QMouseEvent::globalPos () const
Returns the global position of the mouse pointer at the time of the event

See also: globalX() and globalY().

int QMouseEvent::globalX () const
Returns the global X position of the mouse pointer at the time of the event

See also: globalY() and globalPos().

int QMouseEvent::globalY () const
Returns the global Y position of the mouse pointer at the time of the event

See also: globalX() and globalPos().

const QPoint & QMouseEvent::pos () const
Returns the position of the mouse pointer, relative to the widget that received the event.

See also: x() and y().

Examples: qtimage/qtimage.cpp connect/connect.cpp tooltip/tooltip.cpp hello/hello.cpp qmag/qmag.cpp

int QMouseEvent::state () const
Returns the button state (a combination of mouse buttons and keyboard modifiers), i.e. what buttons and keys were being held depressed immediately before the event was generated.

Note that this means that for Event_MouseButtonPress and Event_MouseButtonDblClick, the flag for the button() itself will not be set in the state; while for Event_MouseButtonRelease, it will.

The returned value is LeftButton, RightButton, MidButton, ShiftButton, ControlButton and AltButton OR'ed together.

See also: button().

Examples: movies/main.cpp widgets/widgets.cpp

int QMouseEvent::x () const
Returns the X position of the mouse pointer, relative to the widget that received the event.

See also: y() and pos().

int QMouseEvent::y () const
Returns the Y position of the mouse pointer, relative to the widget that received the event.

See also: x() and pos().
