Java newbie graphics question

[NogginBoink]

I'm a decent programmer but new to java.

I'm writing an applet to play Boggle. (I figured it was the right complexity of project to learn the language.) MY BoggleBoardContainer is a JPanel. The following code compiles and runs but I don't get the rectangle I expect to get. What am I doing wrong?

void DrawDiceOutlines(JPanel BoggleBoardContainer, Color diceBorderColor)
{
BoggleBoardContainer.setBackground(Color.green); //works
Graphics2D G2 = (Graphics2D)BoggleBoardContainer.getGraphics();
G2.setStroke(new BasicStroke (2.0f));
G2.setColor(Color.black);
G2.draw(new Rectangle2D.Double(0,0,300,300)); //doesn't work
}

Hmm, been a while since doing graphics on Java but did you try overriding the paint method and doing this stuff in there?

 

[NogginBoink]

Nope. Trying that now...

How do I get my paint() method called? It's not getting called automatically.

actually- you using Swing? Try subclassing JPanel and override paintComponent (Graphics g) and put your drawing in there. Then use this JPanel instead of the default one.
