An ellipse with a movable center point.
<p>
Paints an ellipse or "pie segment" with a <a href="qbrush.html">QBrush</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="411188"></a>QCanvasEllipse::QCanvasEllipse(<a href="qcanvas.html">QCanvas</a>*canvas)</h3>
<p>Constructs a 32x32 ellipse, centered at (0,0) on <em>canvas.</em>
<h3 class="fn"><a name="d9337c"></a>QCanvasEllipse::QCanvasEllipse(intwidth, intheight, <a href="qcanvas.html">QCanvas</a>*canvas)</h3>
<p>Constructs a <em>width</em> by <em>height</em> pixel ellipse, centered at (0,0)
on <em>canvas.</em>
<h3 class="fn"><a name="107e9d"></a>QCanvasEllipse::QCanvasEllipse(intwidth, intheight, intstartangle, intangle, <a href="qcanvas.html">QCanvas</a>*canvas)</h3>
<p>Constructs a <em>width</em> by <em>height</em> pixel ellipse, centered at (0,0)
on <em>canvas,</em> starting at angle <em>startangle,</em> extending for angle
<em>angle. startangle</em> and <em>angle</em> are in 1/16 degrees.
<h3 class="fn"><a name="e4c429"></a>QCanvasEllipse::~QCanvasEllipse()</h3>
<p>Destructs the ellipse.
<h3 class="fn">int<a name="5e7545"></a>QCanvasEllipse::angleLength()const</h3>
<p>Returns the length angle in 1/16 degrees. Initially this will be
360*16 - ie. a solid ellipse.
<p>See also <a href="#ce53b2">setAngles</a>() and <a href="#329778">angleStart</a>().
<h3 class="fn">int<a name="329778"></a>QCanvasEllipse::angleStart()const</h3>
<p>Returns the start angle in 1/16 degrees. Initially this will be 0.
<p>See also <a href="#ce53b2">setAngles</a>() and <a href="#5e7545">angleLength</a>().
<h3 class="fn"><a href="qpointarray.html">QPointArray</a><a name="3c9333"></a>QCanvasEllipse::areaPoints()const <code>[virtual]</code></h3>
<p>Reimplemented for internal reasons; the API is not affected.
<p>Reimplemented from <a href="qcanvaspolygonalitem.html#3a4360">QCanvasPolygonalItem.</a>
<h3 class="fn">bool<a name="796576"></a>QCanvasEllipse::collidesWith(const<a href="qcanvasitem.html">QCanvasItem</a>*i)const <code>[virtual]</code></h3>
<p>Reimplemented for internal reasons; the API is not affected.

<h3 class="fn">void<a name="f643a0"></a>QCanvasEllipse::drawShape(<a href="qpainter.html">QPainter</a>&p) <code>[virtualprotected]</code></h3>
<p>Draws the ellipse, centered at <a href="qcanvasitem.html#5286ee">x</a>(), <a href="qcanvasitem.html#bf3ff3">y</a>().
<p>Note that <a href="qcanvaspolygon.html">QCanvasPolygon</a> does not support an outline (pen is
always NoPen).
<p>Reimplemented from <a href="qcanvaspolygonalitem.html#5b3192">QCanvasPolygonalItem.</a>
<h3 class="fn">int<a name="480f6e"></a>QCanvasEllipse::height()const</h3>
<p>Returns the height of the ellipse.
<h3 class="fn">int<a name="e2c14f"></a>QCanvasEllipse::rtti()const <code>[virtual]</code></h3>
<p>Returns 6.
<p>See also <a href="qcanvasitem.html#f6cf38">QCanvasItem::rtti</a>().
<p>Reimplemented from <a href="qcanvasitem.html#f6cf38">QCanvasItem.</a>
<h3 class="fn">void<a name="ce53b2"></a>QCanvasEllipse::setAngles(intstart, intlength)</h3>
<p>Sets the angles for the ellipse to start at <em>start</em> and continue
for <em>length</em> units. Each unit is 1/16 of a degree. By default
the ellipse will start at 0 and have length 360*16 - ie. a solid
ellipse.
<p>See also <a href="#329778">angleStart</a>() and <a href="#5e7545">angleLength</a>().
<h3 class="fn">void<a name="343dc3"></a>QCanvasEllipse::setSize(intwidth, intheight)</h3>
<p>Sets the <em>width</em> and <em>height</em> of the ellipse.
<h3 class="fn">int<a name="c212f0"></a>QCanvasEllipse::width()const</h3>
<p>Returns the width of the ellipse.
