fillGradient on a Figure [message #199623]

Hi,

I've got a Figure which contains a title bar and a content pane. The
content pane is of type 'RectangleFigure'. I would like to fill the
content pane with a gradient color.

Overriding the paintFigure(Graphics g) method did not succeed:

paintFigure(Graphics g) {
super.paintFigure(g);
g.fillGradient(this.getContentPane().getClientArea(), true);
}

Then I thought of overriding the method fillShape(Graphics g) of
RectangleFigure but that did not work either. The colors aren't changed
in any way.

Could someone please give me a hint.

Thanks in advance.
Stefan

Overriding fillShape() to invoke fillGradient(getBounds(), bool) should
work. Maybe you need to relaunch your application to see the change?

You could switch to using a plain Figure for the content pane and it
wouldn't cover up your gradient.

Or...

Put a breakpoint to see if the method is called. Also, the foreground and BG
colors are important.

I've done so and overridden paintFigure(Graphics g). Now the gradient
works fine :-)

I put a breakpoint. The method fillShape(Graphics g) of RectangleFigure
was never called...

Thx a lot.

Perhaps the figure had no size and therefore didn't paint?? fill is set to
true by default in Shape.
