[Bug 522152] Re: indicator-application does not send signals when a menu is shown/hidden
I believe this bug is also causing nm-applet to not send scan requests while the networks menu is open. I'm not sure how many people are still using a GNOME desktop with nm-applet rather than gnome-shell, and which is the current default on new installs -- aren't there still environments without gnome-shell selectable from the login screen in the default installation? If so that might still be affecting a large portion of users. None of the workarounds listed above is easily applicable to nm-applet. At the same time it seems that on Fedora this isn't an issue. Is is possible that Fedora uses libappindicator from a different repository, or carries patches for this? Where even is the "upstream" for libappindicator? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/522152 Title: indicator-application does not send signals when a menu is shown/hidden To manage notifications about this bug go to: https://bugs.launchpad.net/grandrock/+bug/522152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 522152] Re: indicator-application does not send signals when a menu is shown/hidden
According to the Freedesktop StatusNotifierItem specification, each StatusNotifierItem object must provide the following methods: - ContextMenu - Activate - SecondaryActivate - Scroll Currently, libappindicator only seem to listen for the `Scroll` method, which it exposes through the `scroll-event` signal, and the `SecondaryActivate`, which it does not expose. Also, the unity-panel-service does not seem to send a `ContextMenu`, `Activate` or `SecondaryActivate` method call to the StatusNotifierItem registered by libappindicator. It does however send the Scroll method call correctly. There are a bunch of other ways in which libappindicator and the unity- panel-service do not follow the StatusNotifierItem specifications. It looks like the unity-panel-service and libappindicator are specifically built to fit the needs of Unity, not to comply with the Freedesktop StatusNotifier spec. To fix this bug properly, firstly the unity-panel-service should send all required method calls to the registered StatusNotifierItem objects. Secondly, libappindicator should listen for these method calls and use this to send signals when the menu is shown/hidden. Note however that the Ubuntu status menu design guidelines explicitly say not to use application indicators when "You just want the program to take up a small space in the panel when minimized". IMO, by making application icons behave more "consistently" inside of Unity, they have become inconsistent with other desktop environments, including the ones from OSX and Windows. I am capable and willing to fix this bug, but I'm afraid doing so allows libappindicator to be used in ways that do not fit the Ubuntu status menu design guidelines. I do not know a lot about the politics in Ubuntu, but this seems to be a touchy subject[3], so my guess is their is no incentive to have it fixed. Could someone set this bug to Won't Fix if this is the case, or tell me where the implementation could be further discussed? Anyhow, I'll be implementing the workaround described above by dlech for my use-case. It seems to work, but might break when the behavior of unity-panel-service changes (however since this bug is already 6 years old, I don't think this will happen soon).

[Bug 522152] Re: indicator-application does not send signals when a menu is shown/hidden
There's a way to work around this problem in unity session but the
workaround is not nice.
The Unity Panel Service sends a signal called 'EntryActivated' via
dbus[1] every time a menu is shown/hidden/changed in the panel. These
signals can be used to determine whether our menu is open or not.
Along with the signal, two properties are sent: entry_id and geometry.
The entry_id uniquely identifies the menu that has just been made
visible. So if the entry_id is the same as the ID of our menu, it's
pretty safe to say that our menu is visible and if it's something else,
our menu should not be visible. But there's a catch: ASFAIK there's no
reliable way to get the entry_id via libappindicator. So we have to
resort in another ugly hack and once again rely on Unity Panel Service.
Unity Panel Service DBus interface[1] has a method called Sync that returns
details about all items in the panel. Here's one example:
('libmessaging.so', '0x7f1d44004d68', 'indicator-messages' ...
So to get the ID for our indicator, we need to find the entry with the
name of our indicator and grab the second item from the tuple. Then it's
just a matter of implementing the logic to figure out whether the menu
is visible or not.
The solution is not optimal and is likely to cause unforeseen problems
but it should make the situation a little better than it currently is.
As another point, I've been trying to figure out how this could be
implemented inside the library. As I know very little about C
programming, I can't help much with the implementation itself but have
investigated how this could possibly be achieved.
There's this mysterious 'visible' property[2] in the DBusMenuItem. If
this property value tells us what the name means, then we should just
connect to the 'property-changed' of the root menu item inside
'setup_dbusmenu' and tell the clients that visibility has changed when
needed. However the documentation states '...whether the menuitem
_should_ be shown or not'. So is the property enough to tell that the
menu is actually visible on the screen or is it just telling Unity that
'Could you please show the menu now' and Unity might show it (normal) -
or not (something has gone very wrong)...
And when it comes to the StatusIcon fallback, implementing this is
nothing more than emitting signal inside 'status_icon_activate' which
actually pops the menu when user clicks the icon. Catching the hide
event is a bit trickier but it may be possible by catching 'visibility-
notify-event' of the menu inherited from gtk_widget (dunno exactly how
the fallback is supposed to work but this seems logical :)).
If any of my thoughts are anywhere near being correct, this doesn't seem
to be so hard thing to implement. Maybe it's just that when this library
isn't used by the default indicators (they all implement their own
DBusMenuServers), it doesn't get that much attention from the devs as it
should...
