It seems that I did not understand.

#check_thread
#update_gui

I thought that when thread.start() is called then it is called on the "background"
Could it be the problem related with visibility_event of TextView?

best regards

Looks like you are updating the TextView buffer from other place different than the main 
thread, Gtk is thread aware but not thread safe, it can't handle GUI updates outside the 
main thread. What I've done is "watch" a variable in the child thread and 
update (in the main thread) the GUI if required.

you can use gtk.events_pending() in a loop to make sure the gui is not frozen 
when checking the child thread.

while True:
     # check_thread
     # update_gui
     while gtk.events_pending():
         gtk.main_iteration_do(False)

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?

Hi Timo,

thank it helps during the showing.
But I think that my way was wrong.

Let's say that I would like to run some command which takes 10minutes (like yum 
installation under Linux)
and I would like to track in TextView all actions.

I think that python thread would be needed, right?
How to solve that issues?

Or are there any other possibilities?

Hi folks,

I have a little bit simple question
In Glade3 I have GtkWindow object
with GtkButton and TextView widget.

What is my goal.
I would like to run some actions when all widgets (like TextView, GtkButton) 
are really visible.

It means when this condition is satisfied then some actions are run and output 
of that actions
are logged into TextView widget.

Actually now I could not find what event should be used for.
It should be some event of GtkWindow, right?

There are some events like visibility_event or show_event, ...
Any advises?
You probable want the realize signal.

window.connect("realize", on_realize)

This will be called when the window is fully shown. This can also be used for 
seperate widgets as it's a GtkWidget signal.

Timo
