Is there any good way to manage the GtkTargets of GtkClipboard?

The problem is: when I claim an ownership of the clipboard, there's no 
convenient way
to manage the targets. I can only use a GtkTargetEntry array, am I right?

To create a GtkTargetEntry array is quite easy, especially for a static 
one. But what I
need is a dynamic one. That does not mean I need add new target without 
reclaim the
ownership. I just have to collect the information about targets before 
set the clipboard
and I may get different targets every time. I don't think it is an 
unusual requirement.
Sure, I can write my own code for dynamic GtkTargetEntry array - create 
the array,
create every gchar array, copy the string, delete the string, delete the 
whole array. I
noticed even Gtk itself don't have enegy to do that.

I understand your unwillingness to add such kind of API. It may be a bad 
one to break
the consistence of clipboard from the other point of view. I sugest to 
add one more API
of set the clipboard with GtkTargetList like:
gboolean gtk_clipboard_set_with_XXX ( GtkClipboard *clipboard,
   const GtkTargetList *targets,
   guint n_targets,
   .... );

At least I can have some API binding with GtkTargetList.
