virtual void draw ( QPainter & painter )


The QCanvasText class provides a text object on a QCanvas.

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 QCanvasItem::move() and QCanvasItem::moveBy(), or by setting coordinates with QCanvasItem::setX(), QCanvasItem::setY() and QCanvasItem::setZ().

Constructs a QCanvasText with the text "<text>", on canvas.

QCanvasText::QCanvasText ( const QString & t, QCanvas * canvas )

Constructs a QCanvasText with the text t, on canvas canvas.

QCanvasText::QCanvasText ( const QString & t, QFont f, QCanvas * canvas )

Constructs a QCanvasText with the text t and font f, on the canvas canvas.

QCanvasText::~QCanvasText () [virtual]

Destroys the canvas text item.

QRect QCanvasText::boundingRect () const [virtual]

Returns the bounding rectangle of the text.

QColor QCanvasText::color () const

Returns the color of the text.

See also setColor().

void QCanvasText::draw ( QPainter & painter ) [virtual protected]

Draws the text using the painter painter.

Reimplemented from QCanvasItem.

QFont QCanvasText::font () const

Returns the font in which the text is drawn.

See also setFont().

int QCanvasText::rtti () const [virtual]

Returns 3 (QCanvasItem::Rtti_Text).

See also QCanvasItem::rtti().

Reimplemented from QCanvasItem.

void QCanvasText::setColor ( const QColor & c )
