Keyboard doesn't work when kpdf or okular are embedded in mozilla firefox usng
mozplugger.
In kpdf you cant use inline search.
In okular you can't even scroll the pdf.

So, by now, i have to use:
repeat noisy fill stream nokill: okular "$file"
instead of default:
repeat noisy swallow(okular) fill: okular "$file"

tried on multiple systems and distributions, using the latest mozplugger:
mozplugger-1.13.1 and firefox 3.on linux 2.6.x

Did it work with 1.13.0? 

Nope, everytime i tried, it never worked well with qt3/4 pdf readers.
I'm surprised nobody submitted this before!

Currently Mozplugger does not handle the keyboard or mouse and takes no part in
deciding which window gets keyboard focus. All it does is reparent the top
level application window (of kpdf ocular, etc) into the window firefox has
allocated for containing the embedded object. Once mozplugger has performed the
reparent operation it takes no part in window handling. That is the application
top-level window becomes a child of one of firefox's windows. Keyboard focus is
controlled by the window manager and is negotated between the window manager
and the clients (i.e. firefox, kpdf and ocular). 

Why it doesnt work I have no idea, so I welcome input from anyone who does.

The reason I asked about if it did work is that I did make a shall change (see
mozdev bug #22065) where before mozplugger returned false when requested if it
supported XEmbed protocol. In version 1.13.1 it now returns true to that
request. I did wondered if this could have been the cause of the problem, but
it does not look so.

Note this is very similar to mozdev bug #19196.

Does release 1.13.3 fix the problem?

Unfortunately it doesnt fix the problem for me. I still can't type into the
search or page number box when embedded in firefox.

I also have a ticket for this opened in the qt bug tracker here:
http://bugreports.qt.nokia.com/browse/QTBUG-3814

Still doesn't work for me too.
I don't tried kpdf, just okular.

I guess this could be a firefox issue. Opened this ticket:

No keyboard recognition at all.

Ubuntu 12.04.1 LTS
Firefox 18.0
Okular: 0.14.3
mozplugger 2.0.2

standart config

There is a general problem when using certain combinations of browser,
application and window manager with the swallow flag. These range from keyboard
focus issues, windows not being swallowed, up to desktop lock up. In all cases
this is because the application is not expecting to be embedded in a browser or
a window manager not expecting another application reparenting windows it
thought it was managing.

Unfortunately I have been unable to find a general fix / work around that can
be applied to mozplugger to cover all cases. Therefore it is recommended not to
use the swallow flag in these cases. Instead use the links flag or if the
application supports it, explicitly tell the application which window to embed
to.
