| This is a default handler for the signal signal_changed().

## Detailed Description

A simple single-line text entry field.

The Gtk::Text widget is a single-line text entry widget. A fairly large set of key bindings are supported by default. If the entered text is longer than the allocation of the widget, the widget will scroll so that the cursor position is visible.

When using an entry for passwords and other sensitive information, it can be put into “password mode” using set_visibility(). In this mode, entered text is displayed using an “invisible” character. By default, GTK picks the best invisible character that is available in the current font, but it can be changed with set_invisible_char().

If you are looking to add icons or progress display in an entry, look at Gtk::Entry. There are other alternatives for more specialized use cases, such as Gtk::SearchEntry. If you need multi-line editable text, look at Gtk::TextView.

Sets whether the contents of the text widget are visible or not.

When visibility is set to false, characters are displayed as the invisible char, and it will also appear that way when the text in the widget is copied to the clipboard.

By default, GTK picks the best invisible character available in the current font, but it can be changed with set_invisible_char().

Note that you probably want to set property_input_purpose() to [enum@.nosp@m.Gtk..nosp@m.Input.nosp@m.Purp.nosp@m.ose.p.nosp@m.assw.nosp@m.ord] or [enum@.nosp@m.Gtk..nosp@m.Input.nosp@m.Purp.nosp@m.ose.p.nosp@m.in] to inform input methods about the purpose of this widget, in addition to setting visibility to false.
