How X11 server generate XClientMessageEvent ?

[Changhui LIU]

Dear Alexandre, 
I'm debugging a window set focus problem on Deepin Linux(www.deepin.org),
I found some hints in handle_wm_protocols function of winex11.drv.
But I feel very strange, I don't find where generate the XClientMessageEvent with event.data.l[0] =
x11drv_atom(WM_TAKE_FOCUS) when I git grep WM_TAKE_FOCUS in wine source directory.


How X11 server generate XClientMessageEvent with event.type = x11drv_atom(WM_PROTOCOLS) 
and event.data.l[0] = x11drv_atom(WM_TAKE_FOCUS) ?


Thank you!

Wine does not generate such messages.  In general, X clients are not supposed to.  The window manager generates them and Wine responds.

Dear Ken:
I see, Thank you. 
The “WM_PROTOCOLS” is a window manager spec.
