DESCRIPTION
The QCanvasRectangle class provides a rectangle on a QCanvas.
This item paints a single rectangle which may have any pen() and
brush(), but may not be tilted/rotated. For rotated rectangles, use
QCanvasPolygon.
The rectangle's size and initial position can be set in the
constructor. The size can be set or changed later using setSize(). Use
height() and width() to retrieve the rectangle's dimensions.
The rectangle can be drawn on a painter with drawShape().
Like any other canvas item rectangles can be moved with
QCanvasItem::move() and QCanvasItem::moveBy(), or by setting
coordinates with QCanvasItem::setX(), QCanvasItem::setY() and
QCanvasItem::setZ().

MEMBER FUNCTION DOCUMENTATIONQCanvasRectangle::QCanvasRectangle ( QCanvas * canvas )
Constructs a rectangle at position (0,0) with both width and height set
to 32 pixels on canvas.
QCanvasRectangle::QCanvasRectangle ( const QRect & r, QCanvas * canvas )
Constructs a rectangle positioned and sized by r on canvas.
QCanvasRectangle::QCanvasRectangle ( int x, int y, int width, int height,
QCanvas * canvas )
Constructs a rectangle at position (x, y) and size width by height, on
canvas.
QCanvasRectangle::~QCanvasRectangle ()
Destroys the rectangle.
QPointArray QCanvasRectangle::chunks () const [virtual protected]
Simply calls QCanvasItem::chunks().
void QCanvasRectangle::drawShape ( QPainter & p ) [virtual protected]
Draws the rectangle on painter p.
Example: canvas/canvas.cpp.
Reimplemented from QCanvasPolygonalItem.
int QCanvasRectangle::height () const
Returns the height of the rectangle.
QRect QCanvasRectangle::rect () const
Returns the integer-converted x(), y() position and size() of the
rectangle as a QRect.
int QCanvasRectangle::rtti () const [virtual]
Returns 5 (QCanvasItem::Rtti_Rectangle).
See also QCanvasItem::rtti().
Reimplemented from QCanvasPolygonalItem.
void QCanvasRectangle::setSize ( int width, int height )
Sets the width and height of the rectangle.
QSize QCanvasRectangle::size () const
Returns the width() and height() of the rectangle.
See also rect() and setSize().
int QCanvasRectangle::width () const
Returns the width of the rectangle.
