I have a question regarding window and button implementation. If I have a toolbar set up, and I have a button on it, is it possible to get it to open a window right within the program? I mean like open up a different section of the program much like the function, notepad1, would do? Or could I get it to imitate the behavior of what the system settings do, where it opens a window completely within the same window? If you can help, I appreciate it. I'm working with the default glade file if that helps anyone.

I'm doing this in my App also. I achieved it by doing something similar to the following:

In your main window get a reference to the widget you want to use as your parent. It must be a derivative of GtkContainer (such as GtkBox). In my instance I did something like the following in my class constructor:

self.itemAsMyContainer = self.builder.get_object("name_of_object_id")

I then used glade to create another, separate ui file with a GtkContainer derivative such (in my case GtkBox) as its top level object, and then modified its Class name in a similar way to how quickly does it. I then created a separate class for it in a similar way to _lib/Window.py in the quickly template. Once that was done I could simply instantiate this new class and attach it to my referenced Container with a piece of code like:

self.my_sub_ui = MySexyGtkContainerSubClass()
self.itemAsMyContainer.pack_start(self.my_sub_ui)

I believe this same approach is possible with another window but you might have to unparent it. See this question for more info on that here

Thanks man, it would have taken me quite a while to find that lol. Have you tried adding the Ambiance theme (on a toolbar/notepad) to your program? I used the code "self.viewport3 = self.builder.get_object("viewport3") but now the problem I am having is that the text is white/inverted (ie: the label "ubuntu" used to be black text, now it is an inverted white). context = self.viewport3.get_style_context() context.add_class(Gtk.STYLE_CLASS_PRIMARY_TOOLBAR)" –  Compt Jun 28 '12 at 13:15
