Comment 2 Olivier Duchateau freebsd_committer 2017-02-20 17:42:23 UTC
Unfortunately your patch is not working. If xfce4-taskmanager is build against Gtk3 it crashes (already reported by OpenBSD users), with Gtk2 everything is fine.

Memory usage is fine, I will commit it.

Comment 4 Ivan Rozhuk 2017-02-20 19:36:19 UTC
I know that with GTK2.0 no crash.
Patch should work, I test it.

Crash was on line:
selection = gtk_tree_view_get_selection (GTK_TREE_VIEW (treeview));
because treeview was null on KILL command.
First I add check:
if (NULL == treeview)
to prevent crash.
Then I see that some one missed set "treeview" for context menu item and add:
g_object_set_data (G_OBJECT (mi), "treeview", treeview);

Please, re test patch.

(In reply to rozhuk.im from comment #4)

Yes, you're right, your patch works fine (I don't know why in my previous test it failed).

We still use Gtk2, for the next major release (2.x) Gtk3 will be the default toolkit (it's developers whish).
Comment 6 Ivan Rozhuk 2017-02-21 06:53:33 UTC
For GTK2 patch should fix deselection after kill.

Can you commit whole patch to ports and to upstream?
Comment 7 Ivan Rozhuk 2017-02-21 20:45:41 UTC
Also, make makepatch generates files without "__".
