## Detailed Description

Completes partial file and directory names given a partial string by looking in the file system for clues.

Can return a list of possible completion strings for widget implementation.

## Member Function Documentation

static Glib::RefPtr<FilenameCompleter> Gio::FilenameCompleter::create | ( |  | ) |
| static

std::string Gio::FilenameCompleter::get_completion_suffix | ( | const std::string & | initial_text | ) | const

Obtains a completion for initial_text from completer.

Parameters

  initial_text | Text to be completed.

Returns
  A completed string, or `nullptr` if no completion exists. This string is not owned by GIO, so remember to Glib::free() it when finished.

Glib::StringArrayHandle Gio::FilenameCompleter::get_completions | ( | const std::string & | initial_text | ) | const

Gets an array of completion strings for a given initial text.

Parameters

  initial_text | Text to be completed.

Returns
  Array of strings with possible completions for initial_text. This array must be freed by Glib::strfreev() when finished.

static GType Gio::FilenameCompleter::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GFilenameCompleter* Gio::FilenameCompleter::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GFilenameCompleter* Gio::FilenameCompleter::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GFilenameCompleter* Gio::FilenameCompleter::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

virtual void Gio::FilenameCompleter::on_got_completion_data | ( |  | ) |
| protectedvirtual

This is a default handler for the signal signal_got_completion_data().

FilenameCompleter& Gio::FilenameCompleter::operator= | ( | FilenameCompleter&& | src | ) |
| noexcept

void Gio::FilenameCompleter::set_dirs_only | ( | bool | dirs_only = `true` | ) |

If dirs_only is `true`, completer will only complete directory names, and not file names.

Parameters

  dirs_only | A `bool`.

Glib::SignalProxy0< void > Gio::FilenameCompleter::signal_got_completion_data | ( |  | ) |

Slot Prototype:
  `void on_my_got_completion_data()`

Emitted when the file name completion information comes available.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::FilenameCompleter > wrap | ( | GFilenameCompleter * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
