<p>Mouse events occur when a mouse cursor is moved into, out of, or within a widget, and if the widget has the <a href="qt.html#WidgetAttribute-enum">Qt.WA_Hover</a> attribute.</p>
<p>The function <a href="qhoverevent.html#pos">pos</a>() gives the current cursor position, while <a href="qhoverevent.html#oldPos">oldPos</a>() gives the old mouse position.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QHoverEvent" />QHoverEvent.__init__ (<i>self</i>, <a href="qevent.html#Type-enum">QEvent.Type</a> <i>type</i>, <a href="qpoint.html">QPoint</a> <i>pos</i>, <a href="qpoint.html">QPoint</a> <i>oldPos</i>)</h3><p>Constructs a hover event object.</p>
<p>The <i>type</i> parameter must be <a href="qevent.html#Type-enum">QEvent.HoverEnter</a>, <a href="qevent.html#Type-enum">QEvent.HoverLeave</a>, or <a href="qevent.html#Type-enum">QEvent.HoverMove</a>.</p>
<p>The <i>pos</i> is the current mouse cursor's position relative to the receiving widget, while <i>oldPos</i> is the previous mouse cursor's position relative to the receiving widget.</p>
<h3 class="fn"><a name="QHoverEvent-2" />QHoverEvent.__init__ (<i>self</i>, <a href="qhoverevent.html">QHoverEvent</a>)</h3><h3 class="fn"><a name="oldPos" /><a href="qpoint.html">QPoint</a> QHoverEvent.oldPos (<i>self</i>)</h3><p>Returns the previous position of the mouse cursor, relative to the widget that received the event. If there is no previous position, oldPos() will return the same position as <a href="qhoverevent.html#pos">pos</a>().</p>
<p>On <a href="qevent.html#Type-enum">QEvent.HoverEnter</a> events, this position will always be <a href="qpoint.html">QPoint</a>(-1, -1).</p>
<p>See also <a href="qhoverevent.html#pos">pos</a>().</p>
<h3 class="fn"><a name="pos" /><a href="qpoint.html">QPoint</a> QHoverEvent.pos (<i>self</i>)</h3><p>Returns the position of the mouse cursor, relative to the widget that received the event.</p>
<p>On <a href="qevent.html#Type-enum">QEvent.HoverLeave</a> events, this position will always be <a href="qpoint.html">QPoint</a>(-1, -1).</p>
