setVisible on a JWindow steals focus from other apps?

Hey all. I need to popup a window without the user necessarily noticing
it immediately. I'm using a technique involving a JWindow that starts
mostly offscreen and slides in to reveal information.

The problem is that when I surface the JWindow with setVisible(true),
the focus is stolen away from other applications, alerting the user too
early and just being annoying. Anyone have any advice on how to fix
this?

What happens when you call toBack() before calling setVisible(true);

Still the same behavior. Whatever application had the focus looses it.

Just subclass JWindow and override the toFront() method so it does nothing.

Hmm. Tried that, and it doesn't seem to help. The real problem is that
I need these windows to be always on top. But when calling
setVisible(true) on something with a non-zero size that has the
setAlwaysOnTop attribute set, I can't seem to avoid the focus stealing.

Thanks for the helpful suggestions so far! Any other thoughts about how
I could acheive a similar effect?

I'm curious if you will be able to do this in Microsoft Windows. Post
here is you find something. Gaining focus and being activated appear
to be windowing system dependent.

Good luck

I have seen "always on top" windows pop up without getting focus under MS
Windows - although rarely, and I don't think any of them were programmed
that way on purpose - more likely it was a side-effect or even
nonreproducible, "random" behaviour. I think it must be possible though,
but it may indeed be OS dependent.

Yes, SetWindowPos with SWP_NOACTIVATE and HWND_TOP or HWND_TOPMOST.

Yesterday/today I wanted window that came up toFront and did not steal
focus. There is method setFocusableWindowState(boolean fs) and I used
it before validate and pack and I get behaviour I was looking for. The
focus stays in app it was in before calling setVisible. The property
stayed after calls to setVisible(false) and setVisible(true).
