I'll take this via my target-arm tree, for convenience's sake.

So I was just trying to test this patch, and I found that at least
for me the osx menu bar has stopped working in QEMU -- keyboard
shortcuts to it still work but none of the menu buttons respond
to the mouse. Does that happen for anybody else?

Also, the "bring up the docs" help option (which is what this
patch is changing) doesn't seem to work when QEMU is run from
the source tree and the docs haven't been installed to the
locations where it expects it might find them. Probably the
code needs updating to work with qemu_find_file() or some
variant on it.

This menu bar breakage appears to be caused by this patch. I have
no idea why, because the patch looks pretty harmless. Nonetheless,
I'm going to have to drop it from my queue.

I think the patch is valid per-se and doubt the patch would cause menu
bar breakage. I had unresponsive menu bar on Catalina even without the
patch.

And I've checked the pre-exesting menu bar issue is resolved in Big Sur
(I assume it was a bug in macOS). As a workaround you might use cmd-tab
or switch focus to another window using mouse and then return it back.

Thanks,
Roman

Well, for me it seemed to be consistent that with this patch the
menu bar didn't work, and without it it did work. I'll have
another look later.

I reproed the "menu bar doesn't work" without this patch, so indeed
it's not to blame. I've put it back in my queue.

It seems like when QEMU initially starts the menu bar doesn't
work; switching to another app and back again makes it start
working. I haven't yet looked through the rest of the discussion
in this thread about possible fixes to this.

There's an old bug when QEMU menu bar is not responsive because it's not
properly activated. If you click off qemu and click on the qemu dock
icon then it "gets fixed" (cmd-tab works too). Do you hit the issue as
described in the article [1]? The code in the article does exactly the
same what I'm doing manually. I wanted to fix it but somehow it got
postponed for like a whole year :) I might try to make a fix this but
note, the issue is not related to the patch.

And click "Help"->"QEMU Documentation". I get the following logs:

In order to get documentation on macOS. sphinx-doc has to be installed
from homebrew. The package is keg-only so sphinx-build has to be added
to PATH.

Then you can build with --enable-docs. Generated documentation resides
in the build tree after the QEMU has been switched to meson:

find . -name index.html
./build/meson-private/temp/sphinx/out/index.html
./build/docs/devel/index.html
./build/docs/tools/index.html
./build/docs/index.html
./build/docs/specs/index.html
./build/docs/interop/index.html
./build/docs/user/index.html
./build/docs/system/index.html

The problem is that the paths above don't point to docs in build tree.
The patch only fixes a warning and doesn't break existing path
resolution. The fix for out-of-tree docs is trivial:
diff --git a/ui/cocoa.m b/ui/cocoa.m

This does not sound like the best solution to the problem. There's some 
info on this here (and blog post linked from it):

https://stackoverflow.com/questions/7460092/nswindow-makekeyandorderfront-makes-window-appear-but-not-key-or-front

Maybe we call makeKeyAndOrderFront: too early before the app is active and 
that's causing the problem? Would it work better if that's moved after 
[NSApp run]? (Maybe we also need canBecomeKey: somewhere but I don't see 
why would that be needed for normal windows.)

JFYI: I'm not sure whether that's related to this, but there was a general 
event handling issue with Gtk3 on macOS which caused mouse events being 
dropped:

https://gitlab.gnome.org/GNOME/gtk/-/issues/986

According to the response, they seem to have fixed it meanwhile with a 
different patch than suggested by me, but I haven't tested theirs.

Hi Christian,

Thanks for the reference. I've looked at the patch and I'm not sure if
the Cocoa issues are related to GTK. It's likely something different.

After skimming over QT bug tracker I found a mathcing ticket that
confirms findings of earlier email:

  https://bugreports.qt.io/browse/QTBUG-89436

  Workaround is to build app as app bundle. Or manually deactivate and
  re-activate the app, like the JavaFX workaround does.

Regards,
Roman

Hi Zoltan,

Thanks for the suggestions. I have tried to move it around but that
doesn't help. Note that minimal cococa app calls makeKeyAndOrderFront:
before [NSApp run] and doesn't experience the issue:
https://github.com/rgl/minimal-cocoa-app/blob/master/main.m

The minimal program that experiences the issue of frozen menubar is:
/* cc -framework Cocoa menufreeze.m */
#import <Cocoa/Cocoa.h>

int main(void) {
    [NSApplication sharedApplication];
    [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];

    dispatch_async(dispatch_get_main_queue(), ^{
        [NSApp activateIgnoringOtherApps:YES];
    });

    [NSApp run];

    return 0;
}

However if the program belongs to an app bundle it doesn't have the
issue. (Simply move a.out into
minimal-cocoa-app.app/Contents/MacOS/minimal-cocoa-app and use "open
minimal-cocoa-app.app" in shell)

Now if we apply the workaround mentioned in the article [1] that
switches focus to Dock and then back to the app we can resolve the issue
in QEMU:

diff --git a/ui/cocoa.m b/ui/cocoa.m

Peter, does it help you? And what version of macOS do you use?

BTW, similar workaround was applied to javafx:
https://github.com/openjdk/jfx/pull/361

However this minimal app does call [NSApp activateIgnoringOtherApps:YES] 
before makeKeyAndOrderFront: and we don't seem to do that. We call 
activateIgnoringOtherApps: in cocoa_display_init() but only if fullscreen 
is set so maybe this should be done differently calling 
activateIgnoringOtherApps: in main unconditionally before calling 
qemu_main() (which creates cocoa_display that needs activated app to call 
toggleFullScreen:) but this has to be after autorelease pool and 
sharedApplication are created. In other words: does moving 
qemu_thread_create(&thread, "qemu_main"...; 
qemu_sem_wait(&display_init_sem) between [QemuApplication 
sharedApplication] and create_initial_menus() help? Or after 
create_initial_menus? That matches better what the minimal app does unless 
there are some other dependencies with other QEMU parts.

This program does not seem to have a menu bar defined so that may be a 
problem. In QEMU we do create a menu bar though.

That's interesting, I don't know what an app bundle has to do with this.

Waiting for a fixed amount of time seems fragile, I still think finding 
the right order of events to make it work would be better but if that's 
not possible I'm OK with whatever workaround others think acceptable.

It's not really important. The minimal app is bundled and if you run it
outside of a bundle you'll get the very same issue we see with QEMU.

You can try it out if you apply the patch to the app (to avoid
references to the data in bundle's plist):
diff --git a/main.m b/main.m

Compile and start it like:

  cc -framework Cocoa main.m
  ./a.out


Then move to the app bundle and it works! So it's a bug in Catalina at
least. We're not the only one who're hitting it:
  https://bugreports.qt.io/browse/QTBUG-89436

  Workaround is to build app as app bundle. Or manually deactivate and
  re-activate the app, like the JavaFX workaround does.

I did try to add activateIgnoringOtherApps: before [NSApp run] and
inside applicationDidFinishLaunching. Neither helps.

It still shows program name (which is part of the menu bar) but it's not
clickable. And even Apple logo/System menu is not responsible. But if
you try to run menufreeze.m on Big Sur menu bar doesn't freeze.  So,
it's quite a valid test case.

I'm happy to hear of other approaches but the workaround fixes the issue
on Catalina without changing user experience. An alternative workaround
is to pack QEMU into App bundle (it is less convenient IMO).

I got round to having another look at this this afternoon.
(I'm using Catalina.) The workaround above does work for me,
though it seems like a pretty nasty one.

I tried the various reshufflings of the code suggested in various bugs,
stack-overflow questions, etc, about where we should call setActivationPolicy,
create menus, call activateIgnoringOtherApps, etc, but they didn't help.

thanks
