The TQCanvasText class provides a text object on a < a href = "ntqcanvas.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 = "qcanvasitem.html#move" > TQCanvasItem::move< / a > () and < a href = "qcanvasitem.html#moveBy" > TQCanvasItem::moveBy< / a > (), or by setting
coordinates with < a href = "qcanvasitem.html#setX" > TQCanvasItem::setX< / a > (), < a href = "qcanvasitem.html#setY" > TQCanvasItem::setY< / a > () and
< a href = "qcanvasitem.html#setZ" > TQCanvasItem::setZ< / a > ().
< p > See also < a href = "graphics.html" > Graphics Classes< / a > and < a href = "images.html" > Image Processing Classes< / a > .
