List of all members.

## Detailed Description

Gtk::FileChooser is an interface that can be implemented by file selection widgets.

In gtkmm, the main objects that implement this interface are FileChooserWidget and FileChooserDialog. You do not need to write an object that implements the FileChooser interface unless you are trying to adapt an existing file selector to expose a standard programming interface.

File Names and Encodings
  When the user is finished selecting files in a FileChooser, your program can get the selected names either as filenames or as URIs. For URIs, the normal escaping rules are applied if the URI contains non-ASCII characters. However, filenames are always returned in the character set specified by the G_FILENAME_ENCODING environment variable. Please see the Glib documentation for more details about this variable.

Important
  This means that while you can pass the result of FileChooser::get_filename() to `open(2)` or `fopen(3)`, you may not be able to directly set it as the text of a Gtk::Label widget unless you convert it first to UTF-8, which all gtkmm widgets expect. You should use Glib::filename_to_utf8() to convert filenames into strings that can be passed to gtkmm widgets.

Note:
  The gtkmm FileChooser API is broken in that methods return Glib::ustring even though the returned string is not necessarily UTF-8 encoded. Any FileChooser method that takes or returns a filename (not a URI) should have std::string as parameter or return type. Fortunately this mistake doesn't prevent you from handling filenames correctly in your application. Just pretend that the API uses std::string and call Glib::filename_to_utf8() or Glib::filename_from_utf8() as appropriate.

bool Gtk::FileChooser::set_current_folder | ( | const Glib::ustring& | filename | ) |

Sets the current folder for chooser from a local filename.

The user will be shown the full contents of the current folder, plus user interface elements for navigating to other folders.

Parameters:

  | filename | The full path of the new current folder.

Returns:
  `true` if the folder could be changed successfully, `false` otherwise.

.

bool Gtk::FileChooser::set_current_folder_uri | ( | const Glib::ustring& | uri | ) |

Sets the current folder for chooser from an URI.

The user will be shown the full contents of the current folder, plus user interface elements for navigating to other folders.

Parameters:

  | uri | The URI for the new current folder.

Returns:
  `true` if the folder could be changed successfully, `false` otherwise.

.

void Gtk::FileChooser::set_current_name | ( | const Glib::ustring& | name | ) |

Sets the current name in the file selector, as if entered by the user.

Note that the name passed in here is a UTF-8 string rather than a filename. This function is meant for such uses as a suggested name in a "Save As..." dialog.

If you want to preselect a particular existing file, you should use set_filename() instead.

Parameters:

  | name | The filename to use, as a UTF-8 string.

void Gtk::FileChooser::set_extra_widget | ( | Gtk::Widget& | extra_widget | ) |

Sets an application-supplied widget to provide extra options to the user.

Parameters:

  | extra_widget | Widget for extra options.

bool Gtk::FileChooser::set_filename | ( | const Glib::ustring& | filename | ) |

Sets filename as the current filename for the the file chooser; If the file name isn't in the current folder of chooser , then the current folder of chooser will be changed to the folder containing filename .

This is equivalent to a sequence of unselect_all() followed by select_filename().

Note that the file must exist, or nothing will be done except for the directory change. To pre-enter a filename for the user, as in a save-as dialog, use set_current_name()

Parameters:

  | filename | The filename to set as current.

Returns:
  `true` if both the folder could be changed and the file was selected successfully, `false` otherwise.

.

void Gtk::FileChooser::set_filter | ( | const FileFilter& | filter | ) |

Sets the current filter; only the files that pass the filter will be displayed.

If the user-selectable list of filters is non-empty, then the filter should be one of the filters in that list. Setting the current filter when the list of filters is empty is useful if you want to restrict the displayed set of files without letting the user change it.

Parameters:

  | filter | A Gtk::FileFilter.

void Gtk::FileChooser::set_local_only | ( | bool | local_only = `true` | ) |

Sets whether only local files can be selected in the file selector.

If local_only is `true` (the default), then the selected file are files are guaranteed to be accessible through the operating systems native file file system and therefore the application only needs to worry about the filename functions in Gtk::FileChooser, like get_filename(), rather than the URI functions like get_uri(),

Parameters:

  | local_only | `true` if only local files can be selected.

void Gtk::FileChooser::set_preview_widget | ( | Gtk::Widget& | preview_widget | ) |

Sets an application-supplied widget to use to display a custom preview of the currently selected file.

To implement a preview, after setting the preview widget, you connect to the update-preview signal, and call get_preview_filename() or get_preview_uri() on each change. If you can display a preview of the new file, update your widget and set the preview active using set_preview_widget_active(). Otherwise, set the preview inactive.

When there is no application-supplied preview widget, or the application-supplied preview widget is not active, the file chooser may display an internally generated preview of the current file or it may display no preview at all.

Parameters:

  | preview_widget | Widget for displaying preview.

void Gtk::FileChooser::set_preview_widget_active | ( | bool | active = `true` | ) |

Sets whether the preview widget set by set_preview_widget_active() should be shown for the current filename.

When active is set to false, the file chooser may display an internally generated preview of the current file or it may display no preview at all. See set_preview_widget() for more details.

Parameters:

  | active | Whether to display the user-specified preview widget.

void Gtk::FileChooser::set_select_multiple | ( | bool | select_multiple = `true` | ) |

Sets whether multiple files can be selected in the file selector.

This is only relevant if the action is set to be GTK_FILE_CHOOSER_ACTION_OPEN or GTK_FILE_CHOOSER_ACTION_SAVE. It cannot be set with either of the folder actions.

Parameters:

  | select_multiple | `true` if multiple files can be selected.

void Gtk::FileChooser::set_show_hidden | ( | bool | show_hidden = `true` | ) |

Sets whether hidden files and folders are displayed in the file selector.

Parameters:

  | show_hidden | `true` if hidden files and folders should be displayed.

bool Gtk::FileChooser::set_uri | ( | const Glib::ustring& | uri | ) |

Sets the file referred to by uri as the current file for the the file chooser; If the file name isn't in the current folder of chooser , then the current folder of chooser will be changed to the folder containing uri .

This is equivalent to a sequence of unselect_all() followed by select_uri().

Note that the file must exist, or nothing will be done except for the directory change. To pre-enter a filename for the user, as in a save-as dialog, use set_current_name()

Parameters:

  | uri | The URI to set as current.

Returns:
  `true` if both the folder could be changed and the URI was selected successfully, `false` otherwise.

.

void Gtk::FileChooser::set_use_preview_label | ( | bool | use_label = `true` | ) |

Sets whether the file chooser should display a stock label with the name of the file that is being previewed; the default is `true`.

Applications that want to draw the whole preview area themselves should set this to `false` and display the name themselves in their preview widget.

See also: set_preview_widget()

Parameters:

  | use_label | Whether to display a stock label with the name of the previewed file.

Glib::SignalProxy0<void> Gtk::FileChooser::signal_current_folder_changed | ( |  | ) |

This signal is emitted when the current folder in a FileChooser changes.

This can happen due to the user performing some action that changes folders, such as selecting a bookmark or visiting a folder on the file list. It can also happen as a result of calling a function to explicitly change the current folder in a file chooser.

Normally you do not need to connect to this signal, unless you need to keep track of which folder a file chooser is showing.

See also:
  set_current_folder(), get_current_folder(), set_current_folder_uri(), get_current_folder_uri().

Glib::SignalProxy0<void> Gtk::FileChooser::signal_file_activated | ( |  | ) |

his signal is emitted when the user "activates" a file in the file chooser.

This can happen by double-clicking on a file in the file list, or by pressing <keycap>Enter</keycap>.

Normally you do not need to connect to this signal. It is used internally by FileChooserDialog to know when to activate the default button in the dialog.

See also:
  get_filename(), get_filenames(), get_uri(), get_uris().

Glib::SignalProxy0<void> Gtk::FileChooser::signal_selection_changed | ( |  | ) |

This signal is emitted when there is a change in the set of selected files in a GtkFileChooser.

This can happen when the user modifies the selection with the mouse or the keyboard, or when explicitly calling functions to change the selection.

Normally you do not need to connect to this signal, as it is easier to wait for the file chooser to finish running, and then to get the list of selected files using the functions mentioned below.

See also:
  select_filename(), unselect_filename(), get_filename(), get_filenames(), select_uri(), unselect_uri(), get_uri(), get_uris().

Glib::SignalProxy0<void> Gtk::FileChooser::signal_update_preview | ( |  | ) |

This signal is emitted when the preview in a file chooser should be regenerated.

For example, this can happen when the currently selected file changes. You should use this signal if you want your file chooser to have a preview widget.

Once you have installed a preview widget with set_preview_widget(), you should update it when this signal is emitted. You can use the functions get_preview_filename() or get_preview_uri() to get the name of the file to preview. Your widget may not be able to preview all kinds of files; your signal handler must call set_preview_wiget_active() to inform the file chooser about whether the preview was generated successfully or not.

See also:
  set_preview_widget(), set_preview_widget_active(), set_use_preview_label(), get_preview_filename(), get_preview_uri().

void Gtk::FileChooser::unselect_all | ( |  | ) |

| Unselects all the files in the current folder of a file chooser.

void Gtk::FileChooser::unselect_filename | ( | const Glib::ustring& | filename | ) |

Unselects a currently selected filename.

If the filename is not in the current directory, does not exist, or is otherwise not currently selected, does nothing.

Parameters:

  | filename | The filename to unselect.

void Gtk::FileChooser::unselect_uri | ( | const Glib::ustring& | uri | ) |

Unselects the file referred to by uri .

If the file is not in the current directory, does not exist, or is otherwise not currently selected, does nothing.

Parameters:

  | uri | The URI to unselect.
