DESCRIPTION

31       The QCanvasRectangle class provides a rectangle on a QCanvas.
32
33       This item paints a single rectangle which may have any pen() and
34       brush(), but may not be tilted/rotated. For rotated rectangles, use
35       QCanvasPolygon.
36
37       The rectangle's size and initial position can be set in the
38       constructor. The size can be set or changed later using setSize(). Use
39       height() and width() to retrieve the rectangle's dimensions.
40
41       The rectangle can be drawn on a painter with drawShape().
42
43       Like any other canvas item rectangles can be moved with
44       QCanvasItem::move() and QCanvasItem::moveBy(), or by setting
45       coordinates with QCanvasItem::setX(), QCanvasItem::setY() and
46       QCanvasItem::setZ().
47
48       See also Graphics Classes and Image Processing Classes.

MEMBER FUNCTION DOCUMENTATION

QCanvasRectangle::QCanvasRectangle ( QCanvas * canvas )

52       Constructs a rectangle at position (0,0) with both width and height set
53       to 32 pixels on canvas.
54

QCanvasRectangle::QCanvasRectangle ( const QRect & r, QCanvas * canvas )

56       Constructs a rectangle positioned and sized by r on canvas.
57

QCanvasRectangle::QCanvasRectangle ( int x, int y, int width, int height,

59       QCanvas * canvas )
60       Constructs a rectangle at position (x, y) and size width by height, on
61       canvas.
62

QCanvasRectangle::~QCanvasRectangle ()

64       Destroys the rectangle.
65

QPointArray QCanvasRectangle::chunks () const [virtual protected]

67       Simply calls QCanvasItem::chunks().
68

void QCanvasRectangle::drawShape ( QPainter & p ) [virtual protected]

70       Draws the rectangle on painter p.
71
72       Example: canvas/canvas.cpp.
73
74       Reimplemented from QCanvasPolygonalItem.
75

int QCanvasRectangle::height () const

77       Returns the height of the rectangle.
78

QRect QCanvasRectangle::rect () const

80       Returns the integer-converted x(), y() position and size() of the
81       rectangle as a QRect.
82

int QCanvasRectangle::rtti () const [virtual]

84       Returns 5 (QCanvasItem::Rtti_Rectangle).
85
86       See also QCanvasItem::rtti().
87
88       Reimplemented from QCanvasPolygonalItem.
89

void QCanvasRectangle::setSize ( int width, int height )

91       Sets the width and height of the rectangle.
92

QSize QCanvasRectangle::size () const

94       Returns the width() and height() of the rectangle.
95
96       See also rect() and setSize().
97

int QCanvasRectangle::width () const

99       Returns the width of the rectangle.
