Detailed 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 Documentation

QCanvasRectangle::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). +

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. +

int QCanvasRectangle::width () const +

+Returns the width of the rectangle. + + +
