iam using the swt java library and iam having a problem.

the gc draw arc method takes the following arguments GC.drawArc(int x, int y, int width, int height, int startAngle, int endAngle);

but i want to be able to draw the arc using 3 arguments : the source ,destination and control points.

is there any formula to convert between those parameters ?

QuadCurve2D class do exactly what i want but it is not AWT not swt ...and i tried to use java2d under swt but it was very slow ....

any solutions ?
