Gtk.EntryBuffer
Description: Reference for Gtk.EntryBuffer

### Class

# GtkEntryBuffer

#### Description [src]

    class Gtk.EntryBuffer : GObject.Object
    {
      /* No available fields */
    }

Holds the text that is displayed in a single-line text entry widget.

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

`GtkEntryBuffer` 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.

#### Properties

###### Gtk.EntryBuffer:length

The length (in characters) of the text in buffer.

###### Gtk.EntryBuffer:max-length

The maximum length (in characters) of the text in the buffer.

###### Gtk.EntryBuffer:text

The contents of the buffer.

#### Signals

###### Gtk.EntryBuffer::deleted-text

The text is altered in the default handler for this signal.

###### Gtk.EntryBuffer::inserted-text

This signal is emitted after text is inserted into the buffer.

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
