Hi,
Im trying to get the gtk_editable_set_position to work. I have a
gtkEntry text box and i first enter "12378978987913".
When I press '4' I expect the cursor to move to the fourth position
gtk_editable_set_position
(GTK_EDITABLE((GtkEntry*)user_data), 4);
But the cursor stays in the same position. Anyone know whats going on?
Depricated gtk_entry_set_position doesnt work either.
Thanks
