GObject property binding support in Glade - Weekly Report 09

[Denis Washington <denisw online de>]

Hi,

I said I would have some more time this weeks than in the numerous weeks 
before, and while I had to do my exams (the two that I wrote went quite 
fine, btw), I was indeed relatively productive!

Besides some minor tweaks to the "Bind to source..." dialog in Glade (it 
showed the property you want to bind to as a valid binding source - 
useless and probably dangerous ;)), I spent most of my work time on my 
"gtkbuilder-gbinding" GTK+ branch - more specifically, teaching it to 
read a transformation function name from a <binding> element and 
locating the function in the same manner as 
gtk_builder_connect_signals() does for signal headers. For this purpose, 
I introduced two new public functions gtk_builder_create_bindings() and 
gtk_builder_create_bindings_full() which correspond to 
gtk_builder_connect_signals() and gtk_builder_connect_signals_full(), 
respectively. (This also means that property bindings aren't create 
implicitly created on gtk_builder_add*() as was done before in this 
branch, but only explicitly by calling the aforementioned functions.) I 
also added the needed documentation and a test case for the new feature 
while I was at it.

My Glade branch also received a basic understanding for transformation 
functions in its data model. It is now able to open files with <binding> 
tags that have a transformation function specified and save them again 
without data loss. Everything else (being able to see and edit the 
transformation function name of a binding) is on my agenda for the next 
one or two weeks.
