Gtk.EntryBuffer – gtk4 – Vala Binding Reference

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.

Namespace: Gtk

Package: gtk4

Content:

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.
