.SH DESCRIPTION
The TQCanvasRectangle class provides a rectangle on a TQCanvas.
.PP
This item paints a single rectangle which may have any pen() and brush(), but may not be tilted/rotated. For rotated rectangles, use TQCanvasPolygon.
.PP
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.
.PP
The rectangle can be drawn on a painter with drawShape().
.PP
Like any other canvas item rectangles can be moved with TQCanvasItem::move() and TQCanvasItem::moveBy(), or by setting coordinates with TQCanvasItem::setX(), TQCanvasItem::setY() and TQCanvasItem::setZ().
.PP

.SH MEMBER FUNCTION DOCUMENTATION
.SH "TQCanvasRectangle::TQCanvasRectangle ( TQCanvas * canvas )"
Constructs a rectangle at position (0,0) with both width and height set to 32 pixels on \fIcanvas\fR.
.SH "TQCanvasRectangle::TQCanvasRectangle ( const TQRect & r, TQCanvas * canvas )"
Constructs a rectangle positioned and sized by \fIr\fR on \fIcanvas\fR.
.SH "TQCanvasRectangle::TQCanvasRectangle ( int x, int y, int width, int height, TQCanvas * canvas )"
Constructs a rectangle at position (\fIx\fR, \fIy\fR) and size \fIwidth\fR by \fIheight\fR, on \fIcanvas\fR.
.SH "TQCanvasRectangle::~TQCanvasRectangle ()"
Destroys the rectangle.
.SH "TQPointArray TQCanvasRectangle::chunks () const\fC [virtual protected]\fR"
Simply calls TQCanvasItem::chunks().
.SH "void TQCanvasRectangle::drawShape ( TQPainter & p )\fC [virtual protected]\fR"
Draws the rectangle on painter \fIp\fR.
.PP
Example: canvas/canvas.cpp.
.PP
Reimplemented from TQCanvasPolygonalItem.
.SH "int TQCanvasRectangle::height () const"
Returns the height of the rectangle.
.SH "TQRect TQCanvasRectangle::rect () const"
Returns the integer-converted x(), y() position and size() of the rectangle as a TQRect.
.SH "int TQCanvasRectangle::rtti () const\fC [virtual]\fR"
Returns 5 (TQCanvasItem::Rtti_Rectangle).
.PP
See also TQCanvasItem::rtti().
.PP
Reimplemented from TQCanvasPolygonalItem.
.SH "void TQCanvasRectangle::setSize ( int width, int height )"
Sets the \fIwidth\fR and \fIheight\fR of the rectangle.
.SH "TQSize TQCanvasRectangle::size () const"
Returns the width() and height() of the rectangle.
.PP
See also rect() and setSize().
.SH "int TQCanvasRectangle::width () const"
Returns the width of the rectangle.
