The QMouseEvent class contains parameters that describe a mouse event. More...
#include <qevent.h>
Inherits QEvent.
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 make 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().
