EditableRef

public struct EditableRef : EditableProtocol

The GtkEditable interface is an interface which should be implemented by text editing widgets, such as GtkEntry and GtkSpinButton. It contains functions for generically manipulating an editable widget, a large number of action signals used for key bindings, and several signals that an application can connect to to modify the behavior of a widget.

As an example of the latter usage, by connecting the following handler to GtkEditable::insert-text, an application can convert all entry into a widget into uppercase.

Forcing entry to uppercase.

(C Language Example):

#include <ctype.h>;

void
insert_text_handler (GtkEditable *editable,
                     const gchar *text,
                     gint         length,
                     gint        *position,
                     gpointer     data)
{
  gchar *result = g_utf8_strup (text, length);

  g_signal_handlers_block_by_func (editable,
                               (gpointer) insert_text_handler, data);
  gtk_editable_insert_text (editable, result, length, position);
  g_signal_handlers_unblock_by_func (editable,
                                     (gpointer) insert_text_handler, data);

  g_signal_stop_emission_by_name (editable, "insert_text");

  g_free (result);
}

The EditableRef type acts as a lightweight Swift reference to an underlying GtkEditable instance. It exposes methods that can operate on this data type through EditableProtocol conformance. Use EditableRef only as an unowned reference to an existing GtkEditable instance.

  • ptr 
    Untyped pointer to the underlying `GtkEditable` instance.

    For type-safe access, use the generated, typed pointer editable_ptr property instead.
