[Glade-devel] Why Glade 3 removes unknown elements

Thank you Tristan :) 

I hadn't seen yet the release 3.14 on yum... arf... now I'm on glade 3.14.2 :-)

I install/update my applications with the yum commandlines... and when I list the "glade3" references, it 
returns only the 3.8.3... To see the last release of Glade, I must list "glade" only, and then... magic... 
the 3.14.2 is there :P magic kick in my ass... I feel a bit silly...

Again a great thank Tristan !

Right... that's the last Glade which supports GTK+2.x

Actually Glade >= 3.10 can be used for projects targeting GTK+2 but special care needs to be taken to avoid 
using any widgets that are new in GTK+3.

The main reason Glade 3.10 does not support GTK+2 is because Glade >= 3.10 needs to link against GTK+ 3 to 
provide new widgets and features...

This basically means that Glade >= 3.10 does not have any support for the removed types which were already 
deprecated in GTK+ 2.24 (anything from GTK+2 that is not included in GTK+3, Glade >= 3.10 does not support).

The feature you are looking for was only ever added to Glade as of 3.14.0 (I searched for it and found it in 
these notes:
http://ftp.gnome.org/pub/gnome/sources/glade/3.14/glade-3.14.0.news)

Since 3.8.x is intended to be supported in the long(ish) term, we do fix bugs in 3.8 because people need it 
to work on GTK+2 projects, introducing such a feature into 3.8 is a kindof grey area (we don't intend to add 
features to Glade 3.8.x, just fix bugs, but this feature is perhaps worth backporting).

However, our focus is on delivering the next stable Glade 3.16, and I can't promise that I will have time to 
backport that feature... as more people are switching to GTK+ 3 for new projects, it's becoming less 
important (but not less demanding) to pay attention to the old 3.8 branch.

Also... are you sure fedora doesnt have a more recent version ?

Note that Glade 3.8 & Glade 3.14 are parallel installable, this was ensured so that people can use an older 
Glade on the same system to edit GTK+2 based Glade projects as well as newer projects which use GTK+3.

Hi Tristan,

I'm running on Glade 3.8.3 under Fedora 18 x64. It's the official Fedora release, I didn't built it from 
the source.

Hi everybody,



I'm building applications to experiment several standards defined by 
EBU. I choose to use Glade to accelerate my developments. I started 
all with Glade
2 and now I decided to switch to Glade 3. I have quickly fixed the 
GtkBox troubles to avoid Glade 3 crashes. All was fine except my Gtk::MenuButton...
Glade 3 removes them automatically from my XML source each time I open it.
Why ???


I think Juan implemented something for that (by storing the unrecognised widget and re-adding the xml at 
save time).

Note that 'custom widgets' Glade 2 style is deprecated in favour of just using a small xml catalog to 
define the custom widgets you want to add in your own project (which will show up in Glade's palette).

What version of Glade are you running, have you tried it with 3.14.x ?

Cheers,
    -Tristan





Glade 2 doesn't support Gtk::MenuButton. So I have converted, into 
the XML source, a  Gtk::Button into a Gtk::MenuButton. It works fine 
and when I open the file into Glade 2 it returns me a warning message 
instead of the Gtk::MenuButton with the choice to suppress or not 
this unknown element (unknown only for Glade, not for the GtkBuilder).



Could you restore this option (ask to user before remove) or add the 
support for Gtk::MenuButton :-) Or must I continue with Glade 2 ???
