[pygtk] Handler for showing window

[Petr Hracek]

Hi,

I have following class and problem is that Thread is started but after a 
short time it is something like paused.
I could not find any reason why.

GUI looks like Window -> Box -> Textview and Cancel Button in VBox widget.

The aim is to open this window and run in thread some application and 
output of that application will be logged in TextView widget

Do you have any idea?
