Xpra: Ticket #77: missing tray icons - forward notification area

XPRA does not display the tray icons of attached applications such as xchat.

and it may never do

This is a very difficult problem to solve - I am not even sure it can be solved:

there are at least two main implementations of "tray icons" on *nix: gtk's "StatusIcon" and Ubuntu's "appindicator" (see #43 for an example of how much of a mess it is to try to support them all)
none of these support overriding at present (and afaik none use dbus..), so the code would have duplicated in each case

Pointers welcome.

Looks like I was wrong about them not using dbus, so we may be able to do something after all (as was done for #22), some more pointers:

Or even by implementing the raw X11 specification: XEmbed).

type changed from defect to enhancement
summary changed from Missing Tray Icons to missing tray icons - forward notification area

comment:3 is wrong about being wrong about dbus (..): the spec does not use dbus, and most apps will not use a dbus interface either, so we must implement the docking tray icon spec directly.

Found pypanel which may serve as a good base for implementing our own tray icon forwarding code.

attachment set to tray-area.patch

adds a hardcoded area for tray icons to dock into - ugly hack for now

Thu, 08 Nov 2012 17:41:48 GMT - Antoine Martin: attachment set

attachment set to tray-area-v2.patch

much more complete implementation

attachment set to tray-area-v3.patch

we can almost click on the forwarded icon too

attachment set to tray-area-v4.patch

updated patch for r2088

attachment set to tray-area-v5.patch

updated patch with cleanups

attachment set to tray-area-v6.patch

work on transparency

Sun, 11 Nov 2012 18:17:12 GMT - Antoine Martin:

r2094 adds the server-side part
r2097 adds the client-side part

It is mostly working as it is, but with some limitations we should address:

missing transparency: we set _NET_SYSTEM_TRAY_VISUAL to the 32-bit visual - but somehow the docking requests we receive are for 24-bit visual windows, not sure why.
popup-menu so we end up simulating a button press and release on the remote tray area. By implementing the system tray using raw X11 calls we ought to be able to get more useful events to forward, the win32 implementation can probably supply the same too in OnTaskbarNotify. We can then use the StatusIcon version as fallback for platforms without native support (ie: osx or pure-python builds).
we should avoid the round-trip via a pixmap backing to get the pixbuf
detect when we lose the tray selection and cleanup
support balloon messages

Sun, 11 Nov 2012 18:24:08 GMT - Antoine Martin: attachment set

attachment set to window-backing-depth.patch

adds the ability to handle 32-bit window backing

Sun, 24 Feb 2013 15:30:10 GMT - Antoine Martin:

We probably also need to split this code into a separate executable so that we can exit/upgrade xpra without losing the trays.

Tue, 05 Mar 2013 10:01:02 GMT - Antoine Martin:

For transparency, see #279

Tue, 21 May 2013 09:11:04 GMT - Antoine Martin:

transparency fixed in r3475 for *nix

Tue, 16 Jul 2013 06:03:37 GMT - Antoine Martin: status changed

status changed from accepted to new

Works well enough.

Tue, 16 Jul 2013 06:03:49 GMT - Antoine Martin: status changed; resolution set

status changed from new to closed
resolution set to fixed

Thu, 31 Oct 2013 12:28:12 GMT - Antoine Martin:

win32 native code in use as of r4640 - which allows us to do things other implementations cannot do: hovering events, etc

Mon, 19 May 2014 12:37:04 GMT - Antoine Martin: milestone changed; version deleted

version 0.0.7.22 deleted
milestone changed from future to 0.8

(setting correct milestone the work was completed in)
