| 56 | The QCanvasPolygon class provides a polygon on a <a href="qcanvas.html">QCanvas</a>.

|
|---|
| 58 | <p>
|
|---|
| 59 |
|
|---|
| 60 |
|
|---|
| 61 | <p> Paints a polygon with a <a href="qbrush.html">QBrush</a>. The polygon's points can be set in
|
|---|
| 62 | the constructor or set or changed later using <a href="#setPoints">setPoints</a>(). Use
|
|---|
| 63 | <a href="#points">points</a>() to retrieve the points, or <a href="#areaPoints">areaPoints</a>() to retrieve the
|
|---|
| 64 | points relative to the canvas's origin.
|
|---|
| 65 | <p> The polygon can be drawn on a painter with <a href="#drawShape">drawShape</a>().
|
|---|
| 66 | <p> Like any other canvas item polygons can be moved with
|
|---|
| 67 | <a href="qcanvasitem.html#move">QCanvasItem::move</a>() and <a href="qcanvasitem.html#moveBy">QCanvasItem::moveBy</a>(), or by setting
|
|---|
| 68 | coordinates with <a href="qcanvasitem.html#setX">QCanvasItem::setX</a>(), <a href="qcanvasitem.html#setY">QCanvasItem::setY</a>() and
|
|---|
| 69 | <a href="qcanvasitem.html#setZ">QCanvasItem::setZ</a>().
|
|---|
| 70 | <p> Note: QCanvasPolygon does not use the pen.

| 113 | their x and y coordinates automatically translated by <a href="qcanvasitem.html#x">x</a>(), <a href="qcanvasitem.html#y">y</a>() as
