.SH DESCRIPTION
|
|
The TQCanvasText class provides a text object on a TQCanvas.
|
|
.PP
|
|
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().
|
|
.PP
|
|
The text can be drawn on a painter with draw().
|
|
.PP
|
|
Like any other canvas item text items can be moved with TQCanvasItem::move() and TQCanvasItem::moveBy(), or by setting coordinates with TQCanvasItem::setX(), TQCanvasItem::setY() and TQCanvasItem::setZ().
|
