Hi.

I am trying to make a button bean, well a set of them having arrows facing in directions (n,s,e,w). I am having great difficulty drawing the triangles which will represent the direction.

I understand you use drawPolygon(i think) to do this but...

In the help features of Net Beans 4.1, it says drawPolygon(int[],int[],int[]);
When i go to try put this in, it totally does not like it.

(Toggle Plain Text)

public LeftButtonBean() {
        super();
        setPreferredSize(new Dimension (50,50));
        setBorder(null);
        buttonColour=Color.black;
    }
    public void paintComponent(Graphics g)
    {
        super.paintComponent(g);
        g.setColor(buttonColour);
        g.drawPolygon();
        
      
    }

right i have that so far, i have left paramaters out of the draw polygon, which gives me "error, cannot find symbol method drawPolygon()".

Right does anyone know how i should go about this, the help just confuses me with its representations of what the parameters needed are.

Before anyone asks, i am a novice in Java programming. Please don't ask "why are you using java?" lol.

Thanks in advance guys.
