[Glade-users] gtk/glade programming

Hi Seb, 

not sure I understood exactly your problem, but check the comments:

Your console_textview is declared in your function, of course this won't work. 
Do you mean the window hasn't yet been created? if so, you should first create it, then you'll have the reference you need.  Something like that:

// assuming you've created a dialog called "console_textview" in Glade.
console_textview = create_console_textview(); 

//shows the console
gtk_widget_show(console_textview); 

Otherwise, if the window has already been created somewhere else, than you should hold a copy of the reference (passing it as a parameter, or .. well, declaring it global, maybe?)

How about a simple buf instead of the whole _() thing? like that:
gtk_text_buffer_set_text (gtk_text_view_get_buffer (GTK_TEXT_VIEW (console_textview)), buf, -1);


Hope it helps,
Günther.
