The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:
Creates a black pen.
Creates the start, end, and two control points for the curve.
Draws the Bézier curve to the screen.
private: void DrawBezierPoint( PaintEventArgs^ e ) { // Create pen. Pen^ blackPen = gcnew Pen( Color::Black,3.0f ); // Create points for curve. Point start = Point(100,100); Point control1 = Point(200,10); Point control2 = Point(350,50); Point end = Point(500,100); // Draw arc to screen. e->Graphics->DrawBezier( blackPen, start, control1, control2, end ); }
