<hr><h2><a name="details"></a>Detailed Description</h2>
The QMouseEvent class contains parameters that describe a mouse event.
<p>
Mouse events occur when a mouse button is pressed or released inside a
widget, or when the mouse cursor is moved.
<p>Mouse move events will only occur when some mouse button is pressed down,
unless <a href="qwidget.html#h5">mouse tracking</a> has been
enabled.
<p>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.
<p>The QWidget::setEnable() function can be used to enable or disable mouse
and keyboard events for a widget.
<p>The <a href="qcursor.html">QCursor</a> widget has static functions for reading and setting the
position of the mouse cursor.
<p>The event handlers <a href="qwidget.html#n4">QWidget::mousePressEvent</a>(), <a href="qwidget.html#n5">QWidget::mouseReleaseEvent</a>(),
<a href="qwidget.html#n6">QWidget::mouseDoubleClickEvent</a>() and <a href="qwidget.html#n7">QWidget::mouseMoveEvent</a>() receive
mouse events.
<p>See also: <a href="qwidget.html#h5">QWidget::setMouseTracking</a>() and <a href="qwidget.html#i7">QWidget::grabMouse</a>().

<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="a0"></a>QMouseEvent::QMouseEvent(inttype, const<a href="qpoint.html">QPoint</a>&pos, intbutton, intstate)</h3>
<p>Constructs a mouse event object.
<p>The type parameter must be <code>Event_MouseButtonPress, Event_MouseButtonRelease, Event_MouseButtonDblClick</code> or <code>Event_MouseMove.</code>
<h3 class="fn">int<a name="a8"></a>QMouseEvent::button()const</h3>
<p>Returns the button that caused the event.
<p>Possible return values are <code>LeftButton, RightButton, MidButton</code> and
<code>NoButton.</code>
<p>Note that the returned value is always <code>NoButton</code> (0) for mouse move
events.
<p>See also: <a href="qmouseevent.html#a9">state</a>().
<p>Examples:
<a href="dclock-dclock-cpp.html#button">dclock/dclock.cpp</a>
<a href="movies-main-cpp.html#button">movies/main.cpp</a>
<a href="widgets-widgets-cpp.html#button">widgets/widgets.cpp</a>
<h3 class="fn">const<a href="qpoint.html">QPoint</a>&<a name="a3"></a>QMouseEvent::globalPos()const</h3>
<p>Returns the global position of the mouse pointer at the time of the event
<p>See also: <a href="qmouseevent.html#a6">globalX</a>() and <a href="qmouseevent.html#a7">globalY</a>().
<h3 class="fn">int<a name="a6"></a>QMouseEvent::globalX()const</h3>
<p>Returns the global X position of the mouse pointer at the time of the event
<p>See also: <a href="qmouseevent.html#a7">globalY</a>() and <a href="qmouseevent.html#a3">globalPos</a>().
<h3 class="fn">int<a name="a7"></a>QMouseEvent::globalY()const</h3>
<p>Returns the global Y position of the mouse pointer at the time of the event
<p>See also: <a href="qmouseevent.html#a6">globalX</a>() and <a href="qmouseevent.html#a3">globalPos</a>().
<h3 class="fn">const<a href="qpoint.html">QPoint</a>&<a name="a2"></a>QMouseEvent::pos()const</h3>
<p>Returns the position of the mouse pointer, relative to the widget that
received the event.
<p>See also: <a href="qmouseevent.html#a4">x</a>() and <a href="qmouseevent.html#a5">y</a>().
<p>Examples:
<a href="qtimage-qtimage-cpp.html#pos">qtimage/qtimage.cpp</a>
<a href="connect-connect-cpp.html#pos">connect/connect.cpp</a>
<a href="tooltip-tooltip-cpp.html#pos">tooltip/tooltip.cpp</a>
<a href="hello-hello-cpp.html#pos">hello/hello.cpp</a>
<a href="qmag-qmag-cpp.html#pos">qmag/qmag.cpp</a>
<h3 class="fn">int<a name="a9"></a>QMouseEvent::state()const</h3>
<p>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.
<p>Note that this means that for <code>Event_MouseButtonPress</code> and <code>Event_MouseButtonDblClick,</code> the flag for the <a href="qmouseevent.html#a8">button</a>() itself will not be
set in the state; while for <code>Event_MouseButtonRelease,</code> it will.
<p>The returned value is <code>LeftButton, RightButton, MidButton, ShiftButton, ControlButton</code> and <code>AltButton</code> OR'ed together.
<p>See also: <a href="qmouseevent.html#a8">button</a>().
<p>Examples:
<a href="movies-main-cpp.html#state">movies/main.cpp</a>
<a href="widgets-widgets-cpp.html#state">widgets/widgets.cpp</a>
<h3 class="fn">int<a name="a4"></a>QMouseEvent::x()const</h3>
<p>Returns the X position of the mouse pointer, relative to the widget that
received the event.
<p>See also: <a href="qmouseevent.html#a5">y</a>() and <a href="qmouseevent.html#a2">pos</a>().
<h3 class="fn">int<a name="a5"></a>QMouseEvent::y()const</h3>
<p>Returns the Y position of the mouse pointer, relative to the widget that
received the event.
<p>See also: <a href="qmouseevent.html#a4">x</a>() and <a href="qmouseevent.html#a2">pos</a>().
