Re: Fwd: Re: Find out if window is active

[Lanoxx <lanoxx gmx net>]

Hi Matthias,

I just installed mutter and tried the use case again, but I am getting 
the same behaviour. I cannot detect any reasonable pattern for the 
is_active flag. It is set to true when I call the application for the 
first time, then it remains true if the application has input focus or 
if I switch to the Thunderbird window from which im writing this E-Mail 
right now. I can switch back the tilda window, when I press the hotkey 
(e.g. F1) but both times the callback is not being called. On the 
otherhand immediately after I start tilda, I can observe that my 
callback function is being called if I press the hotkey to show/hide the 
window a few times. It appears that pressing F1 to show the tilda 
window, does actually cause the window to loose focus, but then through 
the way the callback handler of my hotkey works it immediately becomes 
active again.

When running mutter, i noticed these two messages which repeated several 
times:

Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message 
with a timestamp of 0 for 0x6400003 (tilda)
Window manager warning: meta_window_activate called by a pager with a 0 
timestamp; the pager needs to be fixed.

I do not have a lot of knowledge about X programming, but maybe this 
message is related to the problem. See the following code for how
I show/hide the window:

https://github.com/lanoxx/tilda/blob/master/src/key_grabber.c#L123 //the 
tilda_window_set_active function
and:
https://github.com/lanoxx/tilda/blob/master/src/key_grabber.c#L177 //the 
pull function to show/hide the window
and:

Any help on this is very much appreciated. :)

Kind Regards
Sebastian
