How do I change background color of JTable, when setBackground doesn't work?

Thread view:

tomzam@gmail.com - 30 May 2005 02:51 GMT

I have a JTable that I am displaying in a JScrollpane. The JTable only
displays a few rows of information in its grid. The space below the
grid to the bottom of the JPanel,
that contains the JScrollpane, (Which in turn contains the JTable) is
colored solid gray.
I'd like to change that color to white. I tried setting the JTable's
background color to
white, [using the method setBackground(Color,WHITE) ] but that didn't
work.

Can anyone tell me which method to use to change that gray to white?

Second question.

I have a second JPanel that I put Buttons into. The buttons are gray,
which is fine.
But the buttons themselves are on a gray background.

How do I change that background to white?

I guess my general question is: which methods control the color between
components?

Any help will be appreciated

Set the background color of the scrollpane's viewport:
scrollpane.getViewport().setBackground(Color.RED);

setBackground(Color)
setForeground(Color)
setOpaque(boolean)

Some components are transparent (IIRC a JLabel) so setting background
doesn't seem to have an effect, until you use setOpaque(true) on the
component.
