Method draw_arc

GTK.DrawingArea draw_arc(GDK.GC gc, int filledp, int x1, int y1, int x2, int y2, int angle1, int angle2)

Description

Draws a single circular or elliptical arc. Each arc is specified by a rectangle and two angles. The center of the circle or ellipse is the center of the rectangle, and the major and minor axes are specified by the width and height. Positive angles indicate counterclockwise motion, and negative angles indicate clockwise motion. If the magnitude of angle2 is greater than 360 degrees, it is truncated to 360 degrees.
