<div>>The more I look at this: I’m afraid the crux of this

<br />
<br />
I think you are right. I do not have Ventura to see / test for
myself but everything I am hearing
<br />
sounds like with Stage Manager active the "minimise" button just
causes a different compositing transform
<br />
to be applied to the window and adds that gesture blocking overlay
to make it so that it can't see mouse events
<br />
or presumably receive focus for keyboard events, and the app is
*intentionally* (as in Apple's intention)
<br />
ignorant of anything having changed in its state.<br />
<br />
So it is anyone's guess what we can do about this and even if we
should do something what would it be ..
<br />
Maybe there's some clue in the latest SDK - ie a new API ?<br />
<br />
FWIW One of our team members said he tried this mode for 5 mins
but multiple (non-java) apps were
<br />
so broken in this mode he turned it off again.<br />

<div>Harshitha,</div>
<div><br />
</div>
<div>Thanks for the suggestions. I think those don’t really
resolve the problem, though.
</div>
<div><br />
</div>
<div>In the original sample program (having only 1 frame) watching
the keyboard focus could help identify when there’s a change,
but if there’s a second frame: that second window could retain
the focus and the first window still can’t answer the question,
“Are you minimized now?”
</div>
<div>
<div id="xb7307ab26ea540968109403190bd3a01">
<div><br />
</div>
<div>(I have an updated <a href="https://drive.google.com/file/d/1uzUUDnAlPoHlFdbVgunwpFKvn4Ies-6-/view?usp=sharing" moz-do-not-send="true">sample program</a> here with two
frames if anyone’s interested.)
</div>
<div><br />
</div>
</div>
</div>
<div>Further: the window could lose the focus at any time (if a
system dialog came up), so I don’t think focus should act as a
proxy for visibility.
</div>
<div><br />
</div>
<div>I did find tonight a work-around for our app a few hours ago.
We have some native code that identifies all visible windows,
their bounds and their title. If I consult that list: I see a
window that matches our (sufficiently unique) window title. And
its bounds do not at all match with what Java says our window’s
bounds are. And it is positioned so 99% of it overlaps with a
window called “Gesture Blocking Overlay”. (All Stage Manager
thumbnails appear to have an overlay window with this title.) So
it’s a very kludgy and brittle work around, for for the time
being it works.
</div>
<div><br />
</div>
<div>This leads me to believe the Mac OS windowing system doesn’t
consider the frame to be “hidden”. I think the window remains
technically visible. And Mac OS knows it has new bounds. But the
peer in Java is oblivious to the new bounds/state. (I examined
the peer LWWindowPeer in a debugger: it still thinks the window
is visible (technically true) and its bounds are unchanged (not
true).)
</div>
<div><br />
</div>
<div>The more I look at this: I’m afraid the crux of this problem
is Stage Manager has introduced a new window state that Java’s
AWT architecture can’t really describe yet. (But I’d love to be
proved wrong…?)
