EntryBuffer

Description:

[ CCode ( type_id = "gtk_entry_buffer_get_type ()" ) ]
public class EntryBuffer : Object

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.

Properties:

public uint length { get; }
The length (in characters) of the text in buffer.
public int max_length { get; set; }
The maximum length (in characters) of the text in the buffer.
public string text { get; set; }
The contents of the buffer.

Creation methods:

public EntryBuffer (uint8[]? initial_chars = null)
Create a new `GtkEntryBuffer` object.

Methods:

public virtual uint delete_text (uint position, uint n_chars)
Deletes a sequence of characters from the buffer.
public void emit_deleted_text (uint position, uint n_chars)
Used when subclassing `GtkEntryBuffer`.
public void emit_inserted_text (uint position, uint8[] chars)
Used when subclassing `GtkEntryBuffer`.
public size_t get_bytes ()
Retrieves the length in bytes of the buffer.
public virtual uint get_length ()
Retrieves the length in characters of the buffer.
public int get_max_length ()
Retrieves the maximum allowed length of the text in this.
public unowned string get_text ()
Retrieves the contents of the buffer.
public virtual unowned string get_text_internal (out size_t n_bytes = null)
public virtual uint insert_text (uint position, uint8[] chars)
Inserts n_chars characters of chars into the contents of the buffer, at position position.
public void set_max_length (int max_length)
Sets the maximum allowed length of the contents of the buffer.
public void set_text (uint8[] chars)
Sets the text in the buffer.

Signals:

public virtual signal void deleted_text (uint position, uint n_chars)
The text is altered in the default handler for this signal.
public virtual signal void inserted_text (uint position, string chars, uint n_chars)
This signal is emitted after text is inserted into the buffer.
