Easy.

Do you know about TreeModelFilter?
http://java-gnome.sourceforge.net/4.0/doc/api/org/gnome/gtk/TreeModelFilter.html

You add an Entry where user types.

You write an Entry.Changed handler; there you call TreeModelFilter's
refilter(), then in the TreeModelFilter.Visible you check against the
current text of the Entry.

Yup. You'll want TreeSelection's setMode() to SelectionMode.SINGLE
http://java-gnome.sourceforge.net/4.0/doc/api/org/gnome/gtk/TreeSelection.html#setMode(org.gnome.gtk.SelectionMode)

Easy, Clipboard's setText(), presumably
http://java-gnome.sourceforge.net/4.0/doc/api/org/gnome/gtk/Clipboard.html

[there's a fair bit more complexity available in GtkClipboard we could
expose, but no one has needed it yet]

That's your business, but Widget's hide().

huh? Yikes. You're telling another application to do something? That's
not going to be easy.

That'd just be a simulated keystroke one key at a time. That's probably
not a good idea.

I can see the effect you're going for; within your own application
that'd be do-able.

But one app telling another app what to do (outside of, say, libnotify
or DBus or...) is really sketchy. Heck, only the window manager can
really tell other apps what to do, and even then it's only size and
visibility.

But in any case, the task right now is to keep a journal of clipboard
changes and to be able to replay the selected clipboard item back into
the clipboard on request. Even if you can't force paste elsewhere,
getting the item onto the clipboard will get you most of the way to what
you want.
