Examples of org.eclipse.swt.graphics.GC.fillPolygon()

org.eclipse.swt.graphics.GC.fillPolygon()
Fills the interior of the closed polygon which is defined by the specified array of integer coordinates, using the receiver's background color. The array contains alternating x and y values which are considered to represent points which are the vertices of the polygon. Lines are drawn between each consecutive pair, and between the first pair and last pair in the array. @param pointArray an array of alternating x and y values which are the vertices of the polygon @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT if pointArray is null
@exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
@see #drawPolygon
