Command line for compiling

[Ian Davidson]

I have taken a break from programming over the festivities and have now 
turned my thoughts back to my program.

With my GStreamer console based application, the program's main 'lined 
up all the gstreamer elements', set the ball rolling, and then went to 
g_main_loop_run which waited for interesting signals. I realise that 
there was a lot of multi-threading and other clever stuff going on, but 
what I had to write was impressively simple.

Then I turned to look at my GUI interface and chose GTK as, seemingly, 
the best way to write my code. I notice that the main program lines up 
all the buttons I want on the screen, I have event handlers for when 
buttons are pressed and then I go to gtk_main() to wait for things to 
happen.

My hang-up is that I don't know how to reconcile these two bits of code 
waiting. I think that I have read that gtk_main is a wrapper for 
g_main_loop_run, so there must be something from there that I need to 
incorporate into my main loop. Is there some sample code I can look at?
