Description gtglus 2011-06-28 18:21:49 UTC

From Gtkmm Users List (28.06.2011),

After compiling this tutorial example,

http://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/combobox/text

I get the message below,

Gtk-CRITICAL **: gtk_combo_box_text_get_active_text: assertion
`text_column >= 0' failed

I'm using Gtkmm 3.0.1 with Gtk+ 3.0.11 libraries...

Not sure if it's really a bug...

Confirmed. This happens when selecting an item from the combobox. Here is the backtrace at that warning with "break g_log":

Comment 2 Murray Cumming 2011-06-29 07:42:53 UTC

Fixed in the gtkmm-3-0 and master branches:
http://git.gnome.org/browse/gtkmm/commit/?id=876efee31ba47d8685b6a6d94e64231e2dc292a3

Thanks.

Comment 3 Kjell Ahlstedt 2011-06-29 13:54:28 UTC

The GTK+ bug 650369 emanates from the Python language binding. The problem
described in that bug is probably also caused by gtk_combo_box_text_new()
setting attribute values.

Comment 4 gtglus 2011-08-15 12:16:22 UTC

The bug seems that it has came again in the current last git release...

Comment 5 Murray Cumming 2011-08-15 13:17:00 UTC

> The bug seems that it has came again in the current last git release...

What version do you mean? Does a certain git commit break things for you. It seems fine to me with git master.

Comment 6 Murray Cumming 2011-08-22 07:01:22 UTC

Please reopen if you have some information.

Comment 7 Kjell Ahlstedt 2012-01-03 15:44:11 UTC

The fix in gtk+ bug 612396 comment 67 makes it possible to undo the fix in
this bug's comment 2. Its removal is really not urgent. The fix makes no harm,
it's just unnecessary now.

Comment 8 Murray Cumming 2012-01-03 15:52:11 UTC

Thanks. Could you add a comment about that to the source code? I would prefer to keep the code there, to support older GTK+ versions.
