Absolute layout manager dimensions

Hi again.

Is there any way to create a layout manager consisting of two cols where
the left has a width of 100px and the right one uses the rest of the
space available?

Something like HTML's <frameset cols="100,*"....>

Regards,
Jan

Yes you can create your own LayoutManager to do whatever you like, not great
at making coffee though.
If you want a starting point from existing LayoutManagers, try a
BorderLayout using WEST and CENTER only, in WEST put a JPanel where you have
set preferredSize to have a width of 100px
Be sure you want to give explicit dimensions! Why do you want 100px?

My application has a control panel (which shall 100px) and a plot area
where a graph is drawn... it shall use the rest of the available space.

Then it is unlikely you want to fix size at all then.
You should use a fluid layout and use the layout mangers as they are
intended.
Your user decides the size of the window (or should do) and your application
should adjust its contents accordingly.
This is simplicity itself because there are enough layout managers to suit
99% of needs and that is there job.
You should invest some time suns layout manager tutorial for ex, will
quickly get you up to speed.

You can do this using JGoodies Forms. You can download the Freeware. I
love and use JGoodies forms and LAF Look libs for my Java apps.

not a Layout but something that behaves much like one. See

When you are looking for a layout manager with certain properties,

</hackish psuedo-code>
// nested layout
JPanel theApplication = new JPanel(new BorderLayout());
JPanel theControlPanel = new JPanel() {
getPrefferedSize() {
return new Dimension(100,getHeight());
}
}
JPanel thePlotPanel = new JPanel();
theApplication.add( theControlPanel, BorderLayout.WEST );
theApplication.add( thePlotPanel, BorderLayout.CENTER );
<hackish pseudo-code>

I doubt your '100px' requirement though, if it contains
Java buttons and such, they should be in a layout, and the
panel should be able to tell you how much space it prefers.

But if you mean 100 pixels seriously, you can implement
getPreferredSize getMinimumSize and getMaximumSize or if in JDK 1.5+
use setPreferredSize etc.
