The Q3CanvasText class provides a text object on a Q3Canvas.
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 setText() and setFont(). The color is set with setColor() and the alignment with setTextFlags(). The text item's bounding rectangle is retrieved with boundingRect().
The text can be drawn on a painter with draw().
Like any other canvas item text items can be moved with Q3CanvasItem::move() and Q3CanvasItem::moveBy(), or by setting coordinates with Q3CanvasItem::setX(), Q3CanvasItem::setY() and Q3CanvasItem::setZ().

Constructs a Q3CanvasText with the text "<text>", on canvas.
Constructs a Q3CanvasText with the text t, on canvas canvas.
Constructs a Q3CanvasText with the text t and font f, on the canvas canvas.
Destroys the canvas text item.
Reimplemented from Q3CanvasItem::boundingRect().
Returns the bounding rectangle of the text.
Reimplemented from Q3CanvasItem::collidesWith().
Returns the color of the text.
See also setColor().
Reimplemented from Q3CanvasItem::draw().
Draws the text using the painter painter.
Returns the font in which the text is drawn.
See also setFont().
Reimplemented from Q3CanvasItem::moveBy().
Reimplemented from Q3CanvasItem::rtti().
Returns 3 (Q3CanvasItem::Rtti_Text).
See also Q3CanvasItem::rtti().
Sets the color of the text to the color c.
See also color() and setFont().
Sets the font in which the text is drawn to font f.
See also font().
Sets the text item's text to t. The text may contain newlines.
See also text(), setFont(), setColor(), and setTextFlags().
Sets the alignment flags to f. These are a bitwise OR of the flags available to QPainter::drawText() -- see the Qt::AlignmentFlags.
See also textFlags(), setFont(), and setColor().
Returns the text item's text.
See also setText().
Returns the currently set alignment flags.
