QCanvasRectangle(3qt) QCanvasRectangle(3qt)NAMEQCanvasRectangle - Rectangle on a QCanvasSYNOPSIS#include <qcanvas.h> Inherits QCanvasPolygonalItem. Public Members QCanvasRectangle ( QCanvas * canvas ) QCanvasRectangle ( const QRect & r, QCanvas * canvas ) QCanvasRectangle ( int x, int y, int width, int height, QCanvas * canvas ) ~QCanvasRectangle () int width () const int height () const void setSize ( int width, int height ) QSize size () const QRect rect () const virtual int rtti () const Protected Members virtual void drawShape ( QPainter & p ) virtual QPointArray chunks () constDESCRIPTIONThe 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(). See also Graphics Classes and Image Processing Classes.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.SEE ALSOhttp://doc.trolltech.com/qcanvasrectangle.html http://www.trolltech.com/faq/tech.htmlCOPYRIGHTCopyright 1992-2001 Trolltech AS, http://www.trolltech.com.
