# Gtk2::EntryBuffer(3pm)

wrapper for GtkEntryBuffer

## NAME

Gtk2::EntryBuffer - wrapper for GtkEntryBuffer

## HIERARCHY

```
  Glib::Object
  +----Gtk2::EntryBuffer
```

The **Gtk2::EntryBuffer** class contains the actual text displayed in a Gtk2::Entry widget.

A single Gtk2::EntryBuffer object can be shared by multiple Gtk2::Entry widgets which will then share the same text content, but not the cursor position, visibility attributes, icon etc.

Gtk2::EntryBuffer may be derived from. Such a derived class might allow text to be stored in an alternate location, such as non-pageable memory, useful in the case of important passwords. Or a derived class could integrate with an application's concept of undo/redo.
