<h2>Detailed Description</h2>
<p>The Q3CanvasRectangle class provides a rectangle on a <a href="q3canvas.html">Q3Canvas</a>.</p>
<p>This item paints a single rectangle which may have any <a href="q3canvaspolygonalitem.html#pen">pen</a>() and <a href="q3canvaspolygonalitem.html#brush">brush</a>(), but may not be tilted/rotated. For rotated rectangles, use <a href="q3canvaspolygon.html">Q3CanvasPolygon</a>.</p>
<p>The rectangle's size and initial position can be set in the constructor. The size can be set or changed later using <a href="q3canvasrectangle.html#setSize">setSize</a>(). Use <a href="q3canvasrectangle.html#height">height</a>() and <a href="q3canvasrectangle.html#width">width</a>() to retrieve the rectangle's dimensions.</p>
<p>The rectangle can be drawn on a painter with <a href="q3canvasrectangle.html#drawShape">drawShape</a>().</p>
<p>Like any other canvas item rectangles can be moved with <a href="q3canvasitem.html#move">Q3CanvasItem::move</a>() and <a href="q3canvasitem.html#moveBy">Q3CanvasItem::moveBy</a>(), or by setting coordinates with <a href="q3canvasitem.html#setX">Q3CanvasItem::setX</a>(), <a href="q3canvasitem.html#setY">Q3CanvasItem::setY</a>() and <a href="q3canvasitem.html#setZ">Q3CanvasItem::setZ</a>().</p>
