Custom LnF problem

Hello,

I have a problem that concerns switching from
my custom Look and Feel to the Metal LnF.

When doing this the Metal LnF does not look
the way it is supposed to (wrong colours etc).
For some components the colours are ok, for
others they are not.

My question is therefore, is this is a known
problem with the Metal LnF since Motif and
Windows LnF does appear to look as they should,
or may it be a fault on my behalf?

Thanks,
Robert

Check whether the resources you use in your LnF
implement the UIResource marker interface.
This interface indicates whether a new LnF
can replace an existing border, color, inset,
etc or keeps it because it's a custom resource.

Also, there are a couple of problems when switching
a look-and-feel at runtime. I've worked around
a bunch of them but in general I recommend to
not switch the look at runtime.

Thanks for your help Karsten, I will take
a look at UIResource.

It is a pity that it does not work smoother
when switching from different LnFs. Hopefully
it will be improved in future release of Java.

I have taken a look at other custom LnFs and
it doesn't seem that any LnF manages to switch
in realtime without any hassle.

I'll skip this feature for now.

Mmh, at least you should be able to switch
from the JGoodies LnFs to other LnFs properly
- if you had no other LnF activated before.

I've taken care of all UI delegates to obey
the Swing LnF rules. You can check that in
my tools and demos, for example JDiskReport:

JGoodies LnF are to my knowledge one of the
LnFs that runs most smoothly.

Hopefully my HippoLF will improve over time :-)

It was a typo in my previous mail, I meant to
say that "it doesn't seem that *many* LnF
manages to switch in realtime without any hassle",
not any. My mistake :-/
