Graphics g = null

[bob8000]

Hello to All

Could someone tell me why

Graphics g = getGraphics();

would equal zero

I know it should equal something like

sun.java2d.SunGraphics2D[some other stuff in here]


I am completly stumped on this one

Hi,
Make sure you are calling getGraphics after the form was initialized
and displayed.

Are you calling getGraphics() on a Component? Is it visible? Do you
know where to find the API documentation?

Called on what?
Has whatever you are invoking the method on been realized? A component which
hasn't yet been realized has no Graphics, and getGraphics() will return null.

would equal zero

zero, or null? It should never be zero.

I know it should equal something like

sun.java2d.SunGraphics2D[some other stuff in here]

You mean null? getGraphics() returns null until the component has a
"peer". If you need to pick it up for some code, either do so in
addNotify() or in paint()/paintComponent(), though the latter might be
"too late" for your needs.
