Gtk.EntryBuffer
Description: Reference for Gtk.EntryBuffer

### Class

# GtkEntryBuffer

#### Description [src]

    class Gtk.EntryBuffer : GObject.Object {
      parent_instance: GObject
    }

A `GtkEntryBuffer` hold the text displayed in a `GtkText` 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.

###### gtk_entry_buffer_new

Create a new `GtkEntryBuffer` object.

#### Instance methods

###### gtk_entry_buffer_delete_text

Deletes a sequence of characters from the buffer.

###### gtk_entry_buffer_emit_deleted_text

Used when subclassing `GtkEntryBuffer`.

###### gtk_entry_buffer_emit_inserted_text

Used when subclassing `GtkEntryBuffer`.

###### gtk_entry_buffer_get_bytes

Retrieves the length in bytes of the buffer.

###### gtk_entry_buffer_get_length

Retrieves the length in characters of the buffer.

###### gtk_entry_buffer_get_max_length

Retrieves the maximum allowed length of the text in `buffer`.

###### gtk_entry_buffer_get_text

Retrieves the contents of the buffer.

###### gtk_entry_buffer_insert_text

Inserts `n_chars` characters of `chars` into the contents of the buffer, at position `position`.

###### gtk_entry_buffer_set_max_length

Sets the maximum allowed length of the contents of the buffer.

###### gtk_entry_buffer_set_text

Sets the text in the buffer.

#### 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.
