glade creates GtkBox instead of GtkHBox or GtkVBox

[Frederik Elwert]

Glade creates instances of abstract (non-instantiatable) types, e.g. GtkBox instead of GtkHBox/GtkVBox, GtkPaned instead of GTKHPaned/GtkVPaned, etc.

When loading such a ui file from builder, I get this error message:
"Warning: cannot create instance of abstract (non-instantiatable) type `GtkBox'"

When changing the types by hand in a text editor, the files work.

(This also affects quickly, as it uses glade as its interface designer for GTK apps.)

Glade 3.10 will not include support for gtk2.

see https://bugzilla.gnome.org/show_bug.cgi?id=652673

You can install the binary package from here: https://launchpad.net/~hramrach/+archive/ppa

It did not set my PC on fire but there are no guarantees, as always ;-)

Status changed to 'Confirmed' because the bug affects multiple users.

I can cofirm this bug.

Changing GtkBox to GtkVBox or GtkHBox works for me

[Sebastien Bacher (seb128)]

thank you for your bug report, that's not a bug though, glade 3.10 is meant to be used with gtk3., you can install glade 3.8 as pointed in the comments if you want to work on gtk2

[Frederik Elwert (frederik-elwert)]

The main issue was quickly using glade and PyGTK2.x, which broke quickly projects.

Now glade-gtk2 was packaged and quickly depends on that, so the main issue was resolved.

The remaining issue with glade 3.10 is that it allows to set GTK 2.x as the target version, while not generating compatible code. But this is only a minor issue and probably should be tracked elsewhere.

[Vinycius Maia (mrk3004-deactivatedaccount)]

The glade 'cloud' be perfectly compatible with gtk2 with simple code changes.
In my opinion, this is just a way of pushing us to the development in gtk3

But anyway, this is really 'the future' :)

Using netbeans and I get the same error, I try changing them manually but instead i get this error:
java.text.ParseException: Invalid object type `GtkVBox'

I tried using glade 3.8 but i get the same result. Using "java-gnome hackers" ppa didn't make a change. I checked mailing list and no solution for this but i found a strange explanation of someone who get it working with lazy initialization but i couldn't keep on with this. This shouldn't be this complicated, this combination is supposed to be used as rapid development technique and I already wasted several hours to get nothing.

drianos, your problem is probably in Java and canot be resolved in glade

[Drianos (drianhacon173)]

Michal, I don't think so because I made a window with only a button and it didn't have any problem running the window.
