Re: get process pid from xwindow id with Gnome2::Wnck

[Mario Kemper <mario kemper googlemail com>]

Hi zentara,

i am doing exactly what you want to do in my little Project "GScrot -
Screenshot Tool" (https://launchpad.net/gscrot) .

Maybe you want to have a look at the code:

Sub "fct_gscrot_window" is the interesting part - line 4779.

Greetings
Mario
