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

org.eclipse.swt.graphics.Path.moveTo()
Sets the current point of the receiver to the point specified by (x, y). Note that this starts a new sub path. @param x the x coordinate of the new end point @param y the y coordinate of the new end point @exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
