Re: GtkBuilder property binding syntax

[Emmanuele Bassi <ebassi gmail com>]

hi;

that's not entirely correct: GtkBuilder now allows binding properties
directly in the XML:

> It is also possible to bind a property value to another object's property value using
> the attributes "bind-source" to specify the source object of the binding, "bind-property"
> to specify the source property and optionally "bind-flags" to specify the binding flags

but in order to do that, you'll need the current development tree of
GTK+, 3.13. the next stable version of GTK+ that will support binding
properties directly in the XML, 3.14, is going to be release in
August/September.

for the time being, you'll indeed have to use code.

ciao,
 Emmanuele.
