Lost input when using PyGTK and Panda

Hi evrybody,

we try to do an application using PyGTK and Panda

we read this topic
discourse.panda3d.org/viewtopic.php … hlight=gtk
but we don’t have the same problem.
In fact, we want to use a GUI in PyGTK that changes the object in our Panda window.
We make a panda window that launches a GTK window using this code

taskMgr.add(gtk_iteration, "gtk")

def gtk_iteration(task):
    return Task.cont 

launches one iteration of the gtk main loop

it works, but the problem is that we don’t have input (neither mouse nor keyboard) in our panda window (like when using alt-tab, but the alt cheat doesn’t work)
Does anyone have the same problem ?
