GTKEntry, need help with Multi-Threading & GUI Updating....

[Allen <allen saucier cas-inc com>]

Hello,

Would someone be so kind as to shed some light for me on how I might do 
the following?

1. I have 2 Threads running (Main & one underneath main)
2. In the Sub Thread started by Main, it needs to send or make available 
a double so that the Main's Dialog box will display that double.

I am attempting to pass data from one thread to another thread - that 
works - and I need for the Dialog window - instantiated separately from 
the Main GUI to display that data & update its interface.

I can pass the data to the Dialog box - no problem.  But every time I 
attempt to perform a GUI update using the following code:
   while( Gtk::Main::events_pending() )
     Gtk::Main::iteration(false);

I get gtk errors indicating that there is another thread already 
executing this code - there is, it's Main.  & then the application will 
eventually crash.

So, I do not understand how to properly update a Dialog Box, i.e. 
refresh its screen.  However, whenever I pass the mouse over the Dialog 
box, it refreshes & I see my double value updated in my gtk::entry 
field.  However, I must keep moving the mouse to see this update & 
that's driving me nutts!

Thanks for the help ahead of time! :-)
