The TQCanvasPolygon class provides a polygon on a <a href="qcanvas.html">TQCanvas</a>.
<p>
<p> Paints a polygon with a <a href="qbrush.html">TQBrush</a>. The polygon's points can be set in
the constructor or set or changed later using <a href="#setPoints">setPoints</a>(). Use
<a href="#points">points</a>() to retrieve the points, or <a href="#areaPoints">areaPoints</a>() to retrieve the
points relative to the canvas's origin.
<p> The polygon can be drawn on a painter with <a href="#drawShape">drawShape</a>().
<p> Like any other canvas item polygons can be moved with
<a href="qcanvasitem.html#move">TQCanvasItem::move</a>() and <a href="qcanvasitem.html#moveBy">TQCanvasItem::moveBy</a>(), or by setting
coordinates with <a href="qcanvasitem.html#setX">TQCanvasItem::setX</a>(), <a href="qcanvasitem.html#setY">TQCanvasItem::setY</a>() and
<a href="qcanvasitem.html#setZ">TQCanvasItem::setZ</a>().
<p> Note: TQCanvasPolygon does not use the pen.
<p>See also <a href="graphics.html">Graphics Classes</a> and <a href="images.html">Image Processing Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQCanvasPolygon"></a>TQCanvasPolygon::TQCanvasPolygon ( <a href="qcanvas.html">TQCanvas</a> * canvas )
</h3>
Constructs a point-less polygon on the canvas <em>canvas</em>. You
should call <a href="#setPoints">setPoints</a>() before using it further.
<h3 class=fn><a name="~TQCanvasPolygon"></a>TQCanvasPolygon::~TQCanvasPolygon ()
</h3>
Destroys the polygon.
<h3 class=fn><a href="qpointarray.html">TQPointArray</a> <a name="areaPoints"></a>TQCanvasPolygon::areaPoints () const<tt> [virtual]</tt>
</h3>
Returns the vertices of the polygon translated by the polygon's
current <a href="qcanvasitem.html#x">x</a>(), <a href="qcanvasitem.html#y">y</a>() position, i.e. relative to the canvas's origin.
<p> <p>See also <a href="#setPoints">setPoints</a>() and <a href="#points">points</a>().
<p>Reimplemented from <a href="qcanvaspolygonalitem.html#areaPoints">TQCanvasPolygonalItem</a>.
<h3 class=fn>void <a name="drawShape"></a>TQCanvasPolygon::drawShape ( <a href="qpainter.html">TQPainter</a> & p )<tt> [virtual protected]</tt>
</h3>
Draws the polygon using the painter <em>p</em>.
<p> Note that TQCanvasPolygon does not support an outline (the pen is
always NoPen).
<p>Reimplemented from <a href="qcanvaspolygonalitem.html#drawShape">TQCanvasPolygonalItem</a>.
<h3 class=fn><a href="qpointarray.html">TQPointArray</a> <a name="points"></a>TQCanvasPolygon::points () const
</h3>
<p> Returns the vertices of the polygon, not translated by the position.
<p> <p>See also <a href="#setPoints">setPoints</a>() and <a href="#areaPoints">areaPoints</a>().
<h3 class=fn>int <a name="rtti"></a>TQCanvasPolygon::rtti () const<tt> [virtual]</tt>
</h3>
Returns 4 (TQCanvasItem::Rtti_Polygon).
<p> <p>See also <a href="qcanvasitem.html#rtti">TQCanvasItem::rtti</a>().
<p>Reimplemented from <a href="qcanvaspolygonalitem.html#rtti">TQCanvasPolygonalItem</a>.
<p>Reimplemented in <a href="qcanvasspline.html#rtti">TQCanvasSpline</a>.
<h3 class=fn>void <a name="setPoints"></a>TQCanvasPolygon::setPoints ( <a href="qpointarray.html">TQPointArray</a> pa )
</h3>
Sets the points of the polygon to be <em>pa</em>. These points will have
their x and y coordinates automatically translated by <a href="qcanvasitem.html#x">x</a>(), <a href="qcanvasitem.html#y">y</a>() as
the polygon is moved.
