setClip and drawImage draws over parent

[Seref Arikan]

Hi,
I am currently experimenting with java 2d, and my simple test program shows
odd behaviour (maybe my fault?).
I am using double buffering, and when i use drawimage to draw the offscreen
image to real screen, the image is drawn "over" the parent jscrollpane. The
GUI is structured like this: there is a jframe which contains a jscrollpane,
which contains a jpanel (actually a custom class that's inherited from
jpanel ). I am drawing on jPanel, and if i use setclip to copy only the
shape from offscreen image, the shape is drawn over scrollbars.
If i use getSubImage to take only a part of offscreen image, and NOT use
clipping for the jPanel, i don't have any problems, and i get rid of the
flickering.
So my question is, why setClip uses all area on screen, painting even on
parent control ? How do i avoid it ?
Best Regards

The GUI is structured like this:

Hi,
You're right, that was not a proper way to ask for help. Sorry, i was really
tired. I'll post again with some example code.
Thanks for the links by the way

I would actually not call it 'improper' with all the baggage that
expression carries. Simply 'not the optimal way to obtain assistance
on a technical problem'.

..Sorry, i was really tired.

Get some sleep. You have to look after your health first.

..I'll post again with some example code.

I look forward to it.

You're welcome, I hope it helps to guide you to a resolution.
