a <a href="qtouchevent.html">QTouchEvent</a>.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="id" />int TouchPoint.id (<i>self</i>)</h3><p>Returns the id number of this touch point.</p>
<p>Id numbers are globally sequential, starting at zero, meaning
the first touch point in the application has id 0, the second has
id 1, and so on.</p>
<h3 class="fn"><a name="isPrimary" />bool TouchPoint.isPrimary (<i>self</i>)</h3><p>Returns true if this touch point is the primary touch point. The
primary touch point is the point for which the windowing system
generates mouse events.</p>
<h3 class="fn"><a name="lastNormalizedPos" /><a href="qpointf.html">QPointF</a> TouchPoint.lastNormalizedPos (<i>self</i>)</h3><p>Returns the normalized position of this touch point from the
previous touch event.</p>
<p>The coordinates are normalized to the size of the touch device,
i.e. (0,0) is the top-left corner and (1,1) is the bottom-right
corner.</p>

<a href="qtouchevent-touchpoint.html#startNormalizedPos">startNormalizedPos</a>().</p>
<h3 class="fn"><a name="lastPos" /><a href="qpointf.html">QPointF</a> TouchPoint.lastPos (<i>self</i>)</h3><p>Returns the position of this touch point from the previous touch
event, relative to the widget or <a href="qgraphicsitem.html">QGraphicsItem</a> that received the event.</p>
<p><b>See also</b> <a href="qtouchevent-touchpoint.html#pos">pos</a>() and <a href="qtouchevent-touchpoint.html#startPos">startPos</a>().</p>
<h3 class="fn"><a name="lastScenePos" /><a href="qpointf.html">QPointF</a> TouchPoint.lastScenePos (<i>self</i>)</h3><p>Returns the scene position of this touch point from the previous
touch event.</p>
<p>The scene position is the position in <a href="qgraphicsscene.html">QGraphicsScene</a> coordinates if the
<a href="qtouchevent.html">QTouchEvent</a> is handled by a
QGraphicsItem.touchEvent() reimplementation, and identical to the
screen position for widgets.</p>
