The TQCanvasRectangle class provides a rectangle on a < a href = "tqcanvas.html" > TQCanvas< / a > .
< p >
< p > This item paints a single rectangle which may have any < a href = "tqcanvaspolygonalitem.html#pen" > pen< / a > () and
< a href = "tqcanvaspolygonalitem.html#brush" > brush< / a > (), but may not be tilted/rotated. For rotated rectangles,
use < a href = "tqcanvaspolygon.html" > TQCanvasPolygon< / a > .
< p > The rectangle's size and initial position can be set in the
constructor. The size can be set or changed later using < a href = "#setSize" > setSize< / a > ().
Use < a href = "#height" > height< / a > () and < a href = "#width" > width< / a > () to retrieve the rectangle's dimensions.
< p > The rectangle can be drawn on a painter with < a href = "#drawShape" > drawShape< / a > ().
< p > Like any other canvas item rectangles can be moved with
< a href = "tqcanvasitem.html#move" > TQCanvasItem::move< / a > () and < a href = "tqcanvasitem.html#moveBy" > TQCanvasItem::moveBy< / a > (), or by setting
coordinates with < a href = "tqcanvasitem.html#setX" > TQCanvasItem::setX< / a > (), < a href = "tqcanvasitem.html#setY" > TQCanvasItem::setY< / a > () and
< a href = "tqcanvasitem.html#setZ" > TQCanvasItem::setZ< / a > ().

< h3 class = fn > < a name = "TQCanvasRectangle" > < / a > TQCanvasRectangle::TQCanvasRectangle ( < a href = "tqcanvas.html" > TQCanvas< / a > * canvas )
< / h3 >
Constructs a rectangle at position (0,0) with both width and
height set to 32 pixels on < em > canvas< / em > .
< h3 class = fn > < a name = "TQCanvasRectangle-2" > < / a > TQCanvasRectangle::TQCanvasRectangle ( const < a href = "tqrect.html" > TQRect< / a > & r, < a href = "tqcanvas.html" > TQCanvas< / a > * canvas )
< / h3 >
Constructs a rectangle positioned and sized by < em > r< / em > on < em > canvas< / em > .
< h3 class = fn > < a name = "TQCanvasRectangle-3" > < / a > TQCanvasRectangle::TQCanvasRectangle ( int x, int y, int width, int height, < a href = "tqcanvas.html" > TQCanvas< / a > * canvas )
< / h3 >
Constructs a rectangle at position (< em > x< / em > , < em > y< / em > ) and size < em > width< / em >
by < em > height< / em > , on < em > canvas< / em > .
< h3 class = fn > < a name = "~TQCanvasRectangle" > < / a > TQCanvasRectangle::~TQCanvasRectangle ()
< / h3 >
Destroys the rectangle.
< h3 class = fn > < a href = "tqpointarray.html" > TQPointArray< / a > < a name = "chunks" > < / a > TQCanvasRectangle::chunks () const< tt > [virtual protected]< / tt >
< / h3 >
Simply calls TQCanvasItem::chunks().
< h3 class = fn > void < a name = "drawShape" > < / a > TQCanvasRectangle::drawShape ( < a href = "tqpainter.html" > TQPainter< / a > & p )< tt > [virtual protected]< / tt >
< / h3 >
Draws the rectangle on painter < em > p< / em > .
< p > Example: < a href = "canvas-example.html#x2925" > canvas/canvas.cpp< / a > .
< p > Reimplemented from < a href = "tqcanvaspolygonalitem.html#drawShape" > TQCanvasPolygonalItem< / a > .
< h3 class = fn > int < a name = "height" > < / a > TQCanvasRectangle::height () const
< / h3 >
Returns the height of the rectangle.
< h3 class = fn > < a href = "tqrect.html" > TQRect< / a > < a name = "rect" > < / a > TQCanvasRectangle::rect () const
< / h3 >
< p > Returns the integer-converted < a href = "tqcanvasitem.html#x" > x< / a > (), < a href = "tqcanvasitem.html#y" > y< / a > () position and < a href = "#size" > size< / a > () of the
rectangle as a < a href = "tqrect.html" > TQRect< / a > .
< h3 class = fn > int < a name = "rtti" > < / a > TQCanvasRectangle::rtti () const< tt > [virtual]< / tt >
< / h3 >
Returns 5 (TQCanvasItem::Rtti_Rectangle).
< p > < p > See also < a href = "tqcanvasitem.html#rtti" > TQCanvasItem::rtti< / a > ().
< p > Reimplemented from < a href = "tqcanvaspolygonalitem.html#rtti" > TQCanvasPolygonalItem< / a > .
< h3 class = fn > void < a name = "setSize" > < / a > TQCanvasRectangle::setSize ( int width, int height )
< / h3 >
Sets the < em > width< / em > and < em > height< / em > of the rectangle.
< h3 class = fn > < a href = "tqsize.html" > TQSize< / a > < a name = "size" > < / a > TQCanvasRectangle::size () const
< / h3 >
< p > Returns the < a href = "#width" > width< / a > () and < a href = "#height" > height< / a > () of the rectangle.
< p > < p > See also < a href = "#rect" > rect< / a > () and < a href = "#setSize" > setSize< / a > ().
< h3 class = fn > int < a name = "width" > < / a > TQCanvasRectangle::width () const
< / h3 >
Returns the width of the rectangle.
