NAME

HIERARCHY

9         Glib::Object
10         +----Gtk2::EntryBuffer
11
12       The Gtk2::EntryBuffer class contains the actual text displayed in a
13       Gtk2::Entry widget.
14
15       A single Gtk2::EntryBuffer object can be shared by multiple Gtk2::Entry
16       widgets which will then share the same text content, but not the cursor
17       position, visibility attributes, icon etc.
18
19       Gtk2::EntryBuffer may be derived from. Such a derived class might allow
20       text to be stored in an alternate location, such as non-pageable
21       memory, useful in the case of important passwords. Or a derived class
22       could integrate with an application's concept of undo/redo.
