[Glade-users] Glade / Gtk+ version mismatch and fatal errors

Not quite.

Glade introspects at runtime the properties and signals on GTK+
widgets, an older Glade will still give you access to whatever
properties and signals are available on the GTK+ you are running Glade
against. So an older Glade with a newer GTK+ will still expose new
properties, it will just have an even more outdated internal catalog
and know less about which new properties were introduced in which
version of GTK+.

You could roll back both GTK+ and Glade in your dev environment, or
you could use Glade 3.19 which has *most* new properties and signals
in the catalog.

Better still, if you have a sandbox with GTK+ 3.14, you can use the
glade-previewer program in that sandbox to verify your Glade file and
at least catch these warnings before deploying.

Hi Tristan. Thanks for the reply.

I'm deploying stuff on Windows ( and I'm struggling to build Gtk+ on Windows
- I managed it at one point, but I had to pull in patches from all over the
place, and they no longer apply cleanly ). After more testing, I'm seeing
this kind of issue all over the place now :( I guess the only solution is to
roll back to an earlier version of Glade that matches the target Gtk+
version I'm deploying to.

Hi Daniel,

Glade 3.18 has been a bit stale for quite some time, I recommend that,
if it's possible for you, to build a Glade 3.19 dev snapshot for work
purposes, it has a lot more integration of newer widgets.

Regarding your deployment issue, when in doubt, refer to the GTK+
documentation[0], note that the wide-handle property was introduced in
GTK+ 3.16.

Unfortunately what's happened here is that Glade has introspected the
wide-handle property at runtime, but since Glade's catalog has not
seen any update for a while in Glade 3.18... it does not know what
version wide-handle was introduced in... we admittedly need better
integration with system GIR files (which I think by now should be
providing the 'Since' information) for this to be better automated.

Hi all.

I just created a builder file with Glade-3.18.3. I left the target
as the default ( 3.18 ) and deployed to a system with gtk-3.14.3. I got
error ( which prevented the window from opening at all ):

*** unhandled exception in callback:
***   Invalid property: GtkPaned.wide_handle on line 24 at
c:/strawberry/perl/site/lib/Gtk3.pm line 544.
***   ignoring at c:/starberry/perl/site/lib/Gtk3.pm line 318.

So I went back into glade, loaded this builder file, went to File ==>
Properties and looked at the 'Toolkit version required' area.

The *latest* was 3.12 - which is *earlier* than my gtk version on the
I'm deploying to. Anyway I set it back to 3.8, clicked the 'verify'
button (
there were no version mismatches ), saved, deployed, and tried again.
Unfortunately, I get the same error.

I worked around the issue by unsetting the 'wide handle' toggle on the

It might be better for whatever's throwing this error to make it
