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

org.eclipse.swt.graphics.GC.drawPolyline()
Draws the polyline which is defined by the specified array of integer coordinates, using the receiver's foreground color. The array contains alternating x and y values which are considered to represent points which are the corners of the polyline. Lines are drawn between each consecutive pair, but not between the first pair and last pair in the array. @param pointArray an array of alternating x and y values which are the corners of the polyline @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the point array is null
@exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
