How do I change the L&F of the JavaHelp window? Simply calling
UIManager.setLookAndFeel(aLaF) doesn't work. (Why?)

Many thanks,

Hi,

Changing the L&F won't (I think) modify the UI of already instanciated
Windows.
You may want to apply SwingUtilities.updateComponentTreeUI(Component comp)
on the reluctant components.

But I do the L&F setting *before* anything else. And it works fine with
everything else in the GUI... /ulf

Hi,

Maybe the help frame is statically generated (no idea).

However, I've just tested the following

display a frame
change LaF
display a frame

And the first frame does not change its LaF.

So, if you manage to find the help frame, you should really apply
SwingUtilities.updateComponentTreeUI(helpFrame)

It should work, unless JavaHelp doesn't accept non-default LaFs

Regards,

Arnaud

Try out the following:

UIManager.setLookAndFeel(aLaF);
Frame frames[] = Frame.getFrames();
for (int i = 0; i < frames.length; i++)
SwingUtilities.updateComponentTreeUI(frames[i]);

This should change the L&F of *all* frames of your application,
including the JavaHelp window.
