DESCRIPTION

33       The QCanvasText class provides a text object on a QCanvas.
34
35       A canvas text item has text with font, color and alignment attributes.
36       The text and font can be set in the constructor or set or changed later
37       with setText() and setFont(). The color is set with setColor() and the
38       alignment with setTextFlags(). The text item's bounding rectangle is
39       retrieved with boundingRect().
40
41       The text can be drawn on a painter with draw().
42
43       Like any other canvas item text items can be moved with
44       QCanvasItem::move() and QCanvasItem::moveBy(), or by setting
45       coordinates with QCanvasItem::setX(), QCanvasItem::setY() and
46       QCanvasItem::setZ().
