<h2>Detailed Description</h2>
<p>The Q3CanvasText class provides a text object on a <a href="q3canvas.html">Q3Canvas</a>.</p>
<p>A canvas text item has text with font, color and alignment attributes. The text and font can be set in the constructor or set or changed later with <a href="q3canvastext.html#setText">setText</a>() and <a href="q3canvastext.html#setFont">setFont</a>(). The color is set with <a href="q3canvastext.html#setColor">setColor</a>() and the alignment with <a href="q3canvastext.html#setTextFlags">setTextFlags</a>(). The text item's bounding rectangle is retrieved with <a href="q3canvastext.html#boundingRect">boundingRect</a>().</p>
<p>The text can be drawn on a painter with <a href="q3canvastext.html#draw">draw</a>().</p>
<p>Like any other canvas item text items 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>
