59
60The QCanvasRectangle class provides a rectangle on a <a href="qcanvas.html">QCanvas</a>.
61
62<p>
63
64
65<p> This item paints a single rectangle which may have any <a href="qcanvaspolygonalitem.html#pen">pen</a>() and
66<a href="qcanvaspolygonalitem.html#brush">brush</a>(), but may not be tilted/rotated. For rotated rectangles,
67use <a href="qcanvaspolygon.html">QCanvasPolygon</a>.
68<p> The rectangle's size and initial position can be set in the
69constructor. The size can be set or changed later using <a href="#setSize">setSize</a>().
70Use <a href="#height">height</a>() and <a href="#width">width</a>() to retrieve the rectangle's dimensions.
71<p> The rectangle can be drawn on a painter with <a href="#drawShape">drawShape</a>().
72<p> Like any other canvas item rectangles can be moved with
73<a href="qcanvasitem.html#move">QCanvasItem::move</a>() and <a href="qcanvasitem.html#moveBy">QCanvasItem::moveBy</a>(), or by setting
74coordinates with <a href="qcanvasitem.html#setX">QCanvasItem::setX</a>(), <a href="qcanvasitem.html#setY">QCanvasItem::setY</a>() and
75<a href="qcanvasitem.html#setZ">QCanvasItem::setZ</a>().
