Can I automatically scale a component and all its children?

[Jane Jukowsky]

I am adapting my program for a 800x400 netbook. It's not easy. So I thought, why not just scale the whole thing, like this:

	@Override
	//----------------------------------------------------------------------------------------
	public void paint (Graphics g)
	{
		Graphics2D g2 = (Graphics2D) g;
		g2.scale(.8, .8);
		paint
		super.paint(g);
	}

It works, almost... but of course that does not fool mouse events and such... besides, when mouse goes over any child component, it paints BIG.
So is there a better approach? Maybe someone has done it already?

Thanks

Very good question.
Do you already look for some LAF configurations?

Did you actually get that code to compile? Why are you using paint() not paintComponent()? Shouldn't the super. call be the first statement in the method?

Excellent idea, thanks! I will.

Yes, after taking away line 7

Good point. Using paintComponent() now

Nope. Only in a constructor.

No, in a constructor there is no super. call, only super(). You missed the . You should call super.paintXXX first in such a method, so as to return your component to a pristine state for the next round of painting.

Well, that's a mute point because BasicPaneUI.paint() is not doing anything; otherwise, it would need to be called after g.scale, not before.

The (preferred) size of the component's haven't changed, just the way they look. The look&feel should fix that as well.

That, and the whole mouse event dispatch thingy.
