sorry, but this is confusing...  an object has a property he can't
control..

what if the button doesn't want to be in a military unit ?
there should be a place for freedom and free speech, 
don't you believe?

well, this is another issue, I agree with you that with the current 
aproach is more easy to create an interface by coding it by hand,
but when you come with an interface builder, this complicate all..

And I still have to find a good reason to not use a interface
builder and code the interface by hand.

For example, take glade, put a hbox and then put button A to the
left and then put a button B next to A, now you realize that btn
B must be to the left of A. What you do ?
With the current approach you have to delete both buttons and 
start again (an horrible solution, let me say).
With the property aproach I'm pushing, you just change two properties,
isn't this simpler and more object-oriented-alike ?

(Glade is having a hard time with GtkFixed, for example)

I'm not saying to remove all current containers, only to add a JAC 
(Just Another Container)(and maybe add GTK_RESIZE_NONE as a new 
GtkResizeMode enum), but this one realy does *nothing* more 
than hold the childrens, this childrens behave like they want inside
the new container (one aligned, another fixed, etc).

btw, I've heard that Tim Janik is doing an interface builder, is this
true ?
