How to fill QuadCurve2D in Java Graphics2D

[pars99]

I need to fill an image created using a ton of QuadCurves, but they don't fill it all the way using the traditional fill method. Any suggestions?

public class MonstercatComponent extends JComponent{
    public void paintComponent(Graphics g){
        Graphics2D g2 = (Graphics2D) g;
        drawGrid(g2);

Above is paintComponent which is where all the code is located.

You could try combining all those arcs into a single shape that will then fill properly. A Path2D.Double may be the best option.

secondary

• put all graphics objects to the List

• inside paintComponent loop inside array of Objects

______________________________________________________

important

• don't to call anything from paintComponent - GeneralPath mouthAndTeeth = new GeneralPath(); those object must be prepared before, storred in array of painting,

• paintComponent is designated for custom painting, events are repeatly called, is very insensive,

• not good idea to create an amination this way (remove every code GeneralPath from painting)

• 1st. code line inside paintComponent should be super.paintComponent (reseting background, previous painting, ....)
