Detailed Description

The QtCanvasText class provides a text object on a QtCanvas.

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


Member Function Documentation

QtCanvasText::QtCanvasText ( QtCanvas * canvas )

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

QtCanvasText::QtCanvasText ( const QString & t, QtCanvas * canvas )

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

QtCanvasText::QtCanvasText ( const QString & t, QFont f, QtCanvas * canvas )

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

QtCanvasText::~QtCanvasText ()   [virtual]

Destroys the canvas text item.

QRect QtCanvasText::boundingRect () const   [virtual]

Returns the bounding rectangle of the text.

Reimplemented from QtCanvasItem.

QColor QtCanvasText::color () const

Returns the color of the text.

See also setColor().

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

Draws the text using the painter painter.

Reimplemented from QtCanvasItem.

QFont QtCanvasText::font () const

Returns the font in which the text is drawn.

See also setFont().

int QtCanvasText::rtti () const   [virtual]

Returns 3 (QtCanvasItem::Rtti_Text).

Reimplemented from QtCanvasItem.

See also QtCanvasItem::rtti().

void QtCanvasText::setColor ( const QColor & c )

Sets the color of the text to the color c.

See also color() and setFont().

void QtCanvasText::setFont ( const QFont & f )

Sets the font in which the text is drawn to font f.

See also font().

void QtCanvasText::setText ( const QString & t )

Sets the text item's text to t. The text may contain newlines.

See also text(), setFont(), setColor(), and setTextFlags().

void QtCanvasText::setTextFlags ( int f )

Sets the alignment flags to f. These are a bitwise OR of the flags available to QPainter::drawText() -- see the Qt::AlignmentFlags and Qt::TextFlags.

See also textFlags(), setFont(), and setColor().

QString QtCanvasText::text () const

Returns the text item's text.

See also setText().

int QtCanvasText::textFlags () const

Returns the currently set alignment flags.

See also setTextFlags(), Qt::AlignmentFlag, and Qt::TextFlag.
