Gtk.Editable

const Gtk = imports.gi.Gtk;

let editable = new Gtk.Editable();
  

The Gtk.Editable interface is an interface which should be implemented by text editing widgets, such as Gtk.Entry and Gtk.SpinButton. 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 Gtk.insert-text, an application can convert all entry into a widget into uppercase.

<example> <title>Forcing entry to uppercase.</title> <programlisting> #include &lt;ctype.h&gt;

void insert_text_handler (GtkEditable &ast;editable, const gchar &ast;text, gint length, gint &ast;position, gpointer data) { gchar &ast;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); } </programlisting> </example>
