Hi!

i have a panel in a scrollpane. the panel has a preferred size of 300
x 300 pixel. the scrollpane fits in the main frame, and shows
scrollbars when needed.

i overwrote the paintComponent method, to draw some rectangles.
problem here: the cliparea is not 300 x 300 pixel, but the inside area
of the scrollpane. because of that im not able to draw exactly into
the panel.

I want to reach the following result:

the panel has a constant size of 300 x 300. the scrollpane is
flexible. the panel should always be in the center of the scrollpane,
whenever the scrollpane is larger than 300 x 300 pixel. the unused
space in the scrollpane should be darkgray.
if the scrollpane is resized to a smaller size than 300x300,
scrollbars should appear.

How can i get this effect?

Thanks
