Examples of org.eclipse.swt.graphics.Path.quadTo()

org.eclipse.swt.graphics.Path.quadTo()
Adds to the receiver a quadratic curve based on the parameters. @param cx the x coordinate of the control point of the spline @param cy the y coordinate of the control point of the spline @param x the x coordinate of the end point of the spline @param y the y coordinate of the end point of the spline @exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
