Can we somehow use constants http://developer.gnome.org/pygtk/stable/gtk-constants.html#gtk-response-type-constants instead 1, 2 integers? How can we use them from Glade?

I can't see the video: access denied, forbidden.

Where can I see the video??

The video is not viewable. Just says buffering, no matter how long I wait.

Pity, I can not figure out how to do the UI with glade reading only the text.

One question: if I had to redistribute an app made through GtkBuilder, should I redistribute the XML file together with the binaries?

Here is what I have when using Glade with simple window, label, text entry and button:

As far as I see there is an advantage of using Glade vs coding all the gadgets by hand. I think the guy above is frustrated because Glade and GTK are not self explanatory or self guided tools like Visual Studio for VB or NetBeans for Java. However, once mastered, Glade/GTK can lead to lean and easy to maintain code.

Tutorial was very helpful, thank you!

Big frowns to the guy who wrote the first comment- this guy writes a tutorial and you flame him? Hmm, not impressed.

Again, thanks for this tutorial it has been useful to me! :)

@Anonymous: Hello.

I'm sorry if you feel this way, but this is how things work when creating GUI applications using Glade3. Besides, even if Glade would be able to produce some C code for you, you would still need to write majority of code yourself. GUI builders can only create function declarations and provide you with a skeleton that you need to fill in.

Glade3 sacrificed convenience of creating function declarations in favor of increased maintainability. After all, function declarations are written only once while application needs to be maintained over a longer period of time. Having GUI in a separate file that can be fixed without recompiling your code is really nice.

How is this tutorial useful in anyway ?
I want c code from Glade app and not some crap what i need to do now, why the hell did i even bother to use the gui to build something when i need to do it all manually?????????????

crappy software..................
