Hello,
after you sort the model, you shall consider that all iter and path
previously stored are wrong :
A path is a representation of the position of the row in the current case
(which you can read by using gtk_tree_path_to_string).
I have a question on how I can upgrade my code (Gtk+ v.2.18) that uses
the deprecated GDK_THREAD_ENTER/LEAVE API.
In my case I compute pixbuf in separated threads and I have to lock
the GdkPixbuf creation:
/* thread function */
void _compute_pixbuf ( ...)
{
gchar* pixels;
GdkPixbuf *pixbuf;
/*
Have you try g_object_add_weak_ref ? Weak references are used for
notification when an object is finalized.
Hope this helps.

Hi all,
I've read that GTK+ wants to set gtk_dialog_run and gdk_thread_enter/leave API
I've read messages on why the gdk_thread_enter/leave would be
deprecated but I saw nothing about gtk_dialog_run.
I do not understand especially when we can assume that all GDK/GTK+
calls should be done in the
Hi all,
Is there a way in Glib/Gtk+ to compare 2 strings ignoring the accent
such as g_utf8_casefold does for case insensitive comparison.
I need a function that match :
compare(école,ecole) == 0
Thanks.

You should have read the compiler warning (and the runtime warning) :
the icon_view var is not initialized when you call init_model
GtkWidget *icon_view;
// call of uninitialized icon_view in function init_model
icon_view = gtk_icon_view_new_with_model(init_model(icon_view));
You should have
(cf the link you send). The current
version is available on the gtk homepage. The Gtk-documentation has
really been improved since.
