Threads and input

[Stéphane Raimbault <raimbault stephane free fr>]

Hi,

To start, thank you for GTK+ 2 it's a cool API !

I need to wait on message queue (IPC) so I do that in a 
dedicated thread, I want to show a dialogue box when the data is ready.
The dialog box shows but gtk_dialog_run doesn't return when I click on
button.

To clarify this I wrote a simple prog whith the same structure in
attached file.

Bye 

Stephane
