How to apply look and feel to the whole application

My app has much of panels, forms etc. When applying different LAFs(Look and
feels)
not all the elements change their LAF. It conserns some buttons and panels
which are
integrate into other panels dynamically during working with application. How
can I apply LAF
(e.g. system default) to whole application?

NOTE: if I apply it directly to the component (JButton, etc) than it can get
new LAF. But here I have
very much of such components

Thanks in advance.

Look at UIManager.setLookAndFeel().

Best regards,

The porblem is that method doesn't apply it for whole app. As I mentioned in
original message
it applies it to most but not all the elements. :-/

SwingUtilities.updateComponentTreeUI(component);

You have to call it for every component that's not directly reachable
from your application's frame.

A typical way to do this for the main component to set
up a listener interface where the other components
can register themselves for LAF update events.

The main component, somehow, sets an API that allows
other components to register their listeners. Whenever
the main component decides to change the LAF, it calls
all of the registered listeners to notify them that they
need to update their LAF. The custom event message can
contain the necessary details of the LAF changes, if needed.
Thus, the main component does not need to know all of
the other components in the application. The other components,
however, must know how to register/un-register their listeners.

Just one addition to what the previous posters pointed out: A handy way
to get all(!) frames of your app is the static Frame.getFrames() method.
Frame frames[] = Frame.getFrames();
for (int i = 0; i < frames.length; i++)
SwingUtilities.updateComponentTreeUI(frames[i]);

I wasn't aware of the existence of Frame.getFrames(). I used a similar
technique as mentioned by xarax. I think I'll go and see if it can be
replaced by getFrames() in my app.
