|
|
|
|
|
|
The TQCanvasText class provides a text object on a <a href="tqcanvas.html">TQCanvas</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="#setText">setText</a>() and <a href="#setFont">setFont</a>(). The color is set
|
|
with <a href="#setColor">setColor</a>() and the alignment with <a href="#setTextFlags">setTextFlags</a>(). The text
|
|
item's bounding rectangle is retrieved with <a href="#boundingRect">boundingRect</a>().
|
|
<p> The text can be drawn on a painter with <a href="#draw">draw</a>().
|
|
<p> Like any other canvas item text items can be moved with
|
|
<a href="tqcanvasitem.html#move">TQCanvasItem::move</a>() and <a href="tqcanvasitem.html#moveBy">TQCanvasItem::moveBy</a>(), or by setting
|
|
coordinates with <a href="tqcanvasitem.html#setX">TQCanvasItem::setX</a>(), <a href="tqcanvasitem.html#setY">TQCanvasItem::setY</a>() and
|
|
<a href="tqcanvasitem.html#setZ">TQCanvasItem::setZ</a>().
