Is there a way, in Java, to create windows with the WS_EX_TOPMOST property
set in Windows?

I set the property after creation using JNI, but that appears to be too
late.

I am not familiar with the Windows API you refer to, but I suspect that
might be the same as setting the AlwaysOnTop property for a Window. This
property is new in JDK 1.5.

Unfortunately I've been told that my company won't be using 1.5 for quite
some time due to incompatibilities with a 3rd party library we're depending
on.

Is there another way?

Thanks,

Well, the next thing I would have mentioned is JNI, although you say you
tried that. However, I doubt that the problem you had is because you set
the property too late. It looks to me as if the property can be changed
anytime.

I have a tool that allows me to set this property on arbitrary windows,
and it works anytime. I also just created a test program using JDK 1.5.
It contains a checkbox that allows me to toggle the AlwaysOnTop property
for the frame, and it also works anytime.

BTW - I verified that in both these cases, the WS_EX_TOPMOST Windows style
is being set.
