hovering on a window sitting in the background can cause it to be raised when a tooltip is shown

[peterlong0210]

Reproduce:

1. Server-side, xpra start :100 --start-child=xterm --bind-tcp=0.0.0.0:53000
2. Client-side, xpra attach tcp:IP:100.
3. From xterm, type: firefox. Now Firefox is focused.
4. Focus to xterm. Move your mouse pointer to anywhere which can appear tooltip( for example: title of tabs,...)
5. Tooltip appear and xterm is hidden behind Firefox.
6. Minimize Firefox, xterm is shown, so xterm doesn't minimize, but hidden.

I use Ubuntu 12.04 for server and Windows 7 for client.

I's just check again. It's occur only with tooltip from mouse point in FIREFOX. CHROME is not occur.
PS: Xpra version is 0.14.13 at both client and server

[peterlong0210]

I used -d focus log.
When xterm is hidden behind Firefox, focus not change.

[Antoine Martin]

I'm not sure there's much we can do about this.

-d focus produces log output - which we need to debug things, it is not meant to change the behaviour.

Confirmed on Windows 7 (bug is not present on OSX or Linux clients) - edited title to try to explain it better.

Please provide logs.

I attached a log file.
At server-side:

xpra start :100 --start-child="xterm|firefox" --bind-tcp=0.0.0.0:53000

At client-side:

xpra_cmd attach tcp:192.168.2.55:53000 --encoding=rgb --no-cursor -d focus

You can see more detail from the log file.

I tested also with the xpra.org 0.14.14 fedora 20 server and 0.14.14 windows client r8262 builds.

The server-side log with a -d focus for just the event is here (jimador@zapopan:~ is the xterm window title):

I neglected to grab an xpra info, however. Let me know if that will help and I can grab that as well.

Here's a typical firefox tooltip:

process_new_common: [6, 282, 437, 201, 48, {'opacity': -1, 'fullscreen': False, \
    'xid': '0x8021cd', 'pid': 26134, 'window-type': ('TOOLTIP',), \
    'maximized': False, 'transient-for': 2, 'override-redirect': True}], OR=True

So we have an override redirect "TOOLTIP" window which is transient for its parent.

I've made a much simpler test case for this in r8500.
This is not a bug in our code, it is probably a bug or limitation of GTK on windows. So I am tempted to just close this ticket as 'wontfix' and rely on the GTK3 port making progress (#90).

Could be related to this other GTK focus bug: ticket:469#comment:46.

[Antoine Martin]

Rather than trying to workaround old GTK2 bugs, let's focus on moving to python3 / GTK3:

• #1575 python3 packaging for macos
• #1569 python3 opengl client
