## 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.

## Member Function Documentation

void Gtk::FileChooser::add_filter | ( | const Glib::RefPtr< FileFilter >& | filter | ) |

Adds filter to the list of filters that the user can select between.

When a filter is selected, only files that are passed by that filter are displayed.

Note that the chooser takes ownership of the filter, so you have to ref and sink it if you want to keep a reference.

Since gtkmm 2.4:

Parameters

  filter | A Gtk::FileFilter.

static void Gtk::FileChooser::add_interface | ( | GType | gtype_implementer | ) |

static

bool Gtk::FileChooser::add_shortcut_folder | ( | const std::string & | folder | ) |

Adds a folder to be displayed with the shortcut folders in a file chooser.

Note that shortcut folders do not get saved, as they are provided by the application. For example, you can use this to add a "/usr/share/mydrawprogram/Clipart" folder to the volume list.

Since gtkmm 2.4:

Parameters

  folder | Filename of the folder to add.

Returns
  `true` if the folder could be added successfully, `false` otherwise. In the latter case, the error will be set as appropriate.

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

Adds a folder URI to be displayed with the shortcut folders in a file chooser.

Note that shortcut folders do not get saved, as they are provided by the application. For example, you can use this to add a "file:///usr/share/mydrawprogram/Clipart" folder to the volume list.

Since gtkmm 2.4:

Parameters

  uri | URI of the folder to add.

Returns
  `true` if the folder could be added successfully, `false` otherwise. In the latter case, the error will be set as appropriate.

FileChooserAction Gtk::FileChooser::get_action | ( |  | ) | const

Gets the type of operation that the file chooser is performing; see set_action().

Since gtkmm 2.4:

Returns
  The action that the file selector is performing.

bool Gtk::FileChooser::get_create_folders | ( |  | ) | const

Gets whether file choser will offer to create new folders.

See set_create_folders().

Since gtkmm 2.18:

Returns
  `true` if the New Folder button should be displayed.

std::string Gtk::FileChooser::get_current_folder | ( |  | ) | const

Gets the current folder of chooser as a local filename.

See set_current_folder().

Since gtkmm 2.4:

Returns
  The full path of the current folder, possibly empty if the current path cannot be represented as a local filename. This function may also return and empty string if the file chooser was unable to load the last folder that was requested from it; for example, as would be for calling set_current_folder() on a nonexistent folder.

Glib::RefPtr<Gio::File> Gtk::FileChooser::get_current_folder_file | ( |  | ) |

Gets the current folder of chooser as File.

See get_current_folder_uri().

Since gtkmm 2.14:

Returns
  The File for the current folder.

Glib::ustring Gtk::FileChooser::get_current_folder_uri | ( |  | ) | const

Gets the current folder of chooser as an URI.

See set_current_folder_uri().

Note that this is the folder that the file chooser is currently displaying (e.g. "file:///home/username/Documents"), which is not the same as the currently-selected folder if the chooser is in Gtk::FILE_CHOOSER_ACTION_SELECT_FOLDER mode (e.g. "file:///home/username/Documents/selected-folder/". To get the currently-selected folder in that mode, use get_uri() as the usual way to get the selection.

Since gtkmm 2.4:

Returns
  The URI for the current folder.

Glib::ustring Gtk::FileChooser::get_current_name | ( |  | ) | const

Gets the current name in the file selector, as entered by the user in the text entry for "Name".

This is meant to be used in save dialogs, to get the currently typed filename when the file itself does not exist yet. For example, an application that adds a custom extra widget to the file chooser for "file format" may want to change the extension of the typed filename based on the chosen format, say, from ".jpg" to ".png".

Since gtkmm 3.10:

Returns
  The raw text from the file chooser's "Name" entry. Free this with Glib::free(). Note that this string is not a full pathname or URI; it is whatever the contents of the entry are. Note also that this string is in UTF-8 encoding, which is not necessarily the system's encoding for filenames.

bool Gtk::FileChooser::get_do_overwrite_confirmation | ( |  | ) | const

Queries whether a file chooser is set to confirm for overwriting when the user types a file name that already exists.

Since gtkmm 2.8:

Returns
  `true` if the file chooser will present a confirmation dialog; `false` otherwise.

Gtk::Widget* Gtk::FileChooser::get_extra_widget | ( |  | ) |

Gets the current preview widget; see set_extra_widget().

Since gtkmm 2.4:

Returns
  The current extra widget, or `0`.

void Gtk::FileChooser::select_all | ( |  | ) |

Selects all the files in the current folder of a file chooser.

Since gtkmm 2.4:

bool Gtk::FileChooser::select_file | ( | const Glib::RefPtr< const Gio::File > & | file | ) |

Selects the file referred to by file.

An internal function. See _gtk_file_chooser_select_uri().

Since gtkmm 2.14:

Parameters

  file | The file to select.

Returns
  Not useful.

bool Gtk::FileChooser::select_filename | ( | const std::string & | filename | ) |

Selects a filename.

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.

Since gtkmm 2.4:

Parameters

  filename | The filename to select.

Returns
  Not useful.

See also: set_filename().

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

Selects the file to by uri.

If the URI doesn't refer to a file in the current folder of chooser, then the current folder of chooser will be changed to the folder containing filename.

Since gtkmm 2.4:

Parameters

  uri | The URI to select.

Returns
  Not useful.

void Gtk::FileChooser::set_action | ( | FileChooserAction | action | ) |

Sets the type of operation that the chooser is performing; the user interface is adapted to suit the selected action.

For example, an option to create a new folder might be shown if the action is Gtk::FILE_CHOOSER_ACTION_SAVE but not if the action is Gtk::FILE_CHOOSER_ACTION_OPEN.

Since gtkmm 2.4:

Parameters

  action | The action that the file selector is performing.

void Gtk::FileChooser::set_create_folders | ( | bool | create_folders = `true` | ) |

Sets whether file choser will offer to create new folders.

This is only relevant if the action is not set to be Gtk::FILE_CHOOSER_ACTION_OPEN.

Since gtkmm 2.18:

Parameters

  create_folders | `true` if the New Folder button should be displayed.

bool Gtk::FileChooser::set_current_folder | ( | const std::string & | 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.

In general, you should not use this function. See the section on setting up a file chooser dialog for the rationale behind this.

Since gtkmm 2.4:

Parameters

  filename | The full path of the new current folder.

Returns
  Not useful.

bool Gtk::FileChooser::set_current_folder_file | ( | const Glib::RefPtr< const Gio::File > & | file | ) |

Internal function, see set_current_folder_uri().

Since gtkmm 2.14:

Parameters

  file | The File for the new 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.

In general, you should not use this function. See the section on setting up a file chooser dialog for the rationale behind this.

Since gtkmm 2.4:

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. You can pass "Untitled.doc" or a similarly suitable suggestion for the name.

If you want to preselect a particular existing file, you should use set_filename() or set_uri() instead. Please see the documentation for those functions for an example of using set_current_name() as well.

Since gtkmm 2.4:

Parameters

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

void Gtk::FileChooser::set_do_overwrite_confirmation | ( | bool | do_overwrite_confirmation = `true` | ) |

Sets whether a file chooser in Gtk::FILE_CHOOSER_ACTION_SAVE mode will present a confirmation dialog if the user types a file name that already exists.

This is `false` by default.

If set to `true`, the chooser will emit the Gtk::FileChooser::signal_confirm_overwrite() signal when appropriate.

If all you need is the stock confirmation dialog, set this property to `true`. You can override the way confirmation is done by actually handling the Gtk::FileChooser::signal_confirm_overwrite() signal; please refer to its documentation for the details.

Since gtkmm 2.8:

Parameters

  do_overwrite_confirmation | Whether to confirm overwriting in save mode.

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

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

Since gtkmm 2.4:

Parameters

  extra_widget | Widget for extra options.

bool Gtk::FileChooser::set_file | ( | const Glib::RefPtr< const Gio::File > & | file | ) |

Sets file as the current filename for the file chooser, by changing to the file's parent folder and actually selecting the file in list.

If the chooser is in Gtk::FILE_CHOOSER_ACTION_SAVE mode, the file's base name will also appear in the dialog's file name entry.

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.

If you are implementing a `File/Save As...` dialog, you should use this function if you already have a file name to which the user may save; for example, when the user opens an existing file and then does `File/Save As...` on it. If you don't have a file name already — for example, if the user just created a new file and is saving it for the first time, do not call this function. Instead, use something similar to this:

[C example ellipted]

Since gtkmm 2.14:

Parameters

  file | The File to set as current.

Returns
  Not useful.

bool Gtk::FileChooser::set_filename | ( | const std::string & | filename | ) |

Sets filename as the current filename for the file chooser, by changing to the file's parent folder and actually selecting the file in list; all other files will be unselected.

If the chooser is in Gtk::FILE_CHOOSER_ACTION_SAVE mode, the file's base name will also appear in the dialog's file name entry.

Note that the file must exist, or nothing will be done except for the directory change.

You should use this function only when implementing a `File/Save As...` dialog for which you already have a file name to which the user may save. For example, when the user opens an existing file and then does `File/Save As...` on it to save a copy or a modified version. If you don't have a file name already — for example, if the user just created a new file and is saving it for the first time, do not call this function. Instead, use something similar to this:

[C example ellipted]

In the first case, the file chooser will present the user with useful suggestions as to where to save his new file. In the second case, the file's existing location is already known, so the file chooser will use it.

Since gtkmm 2.4:

Parameters

  filename | The filename to set as current.

Returns
  Not useful.

void Gtk::FileChooser::set_filter | ( | const Glib::RefPtr< 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.

Since gtkmm 2.4:

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(),

On some systems non-native files may still be available using the native filesystem via a userspace filesystem (FUSE).

Since gtkmm 2.4:

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 Gtk::FileChooser::signal_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 will display no preview at all.

Since gtkmm 2.4:

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() 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.

Since gtkmm 2.4:

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_SELECT_FOLDER.

Since gtkmm 2.4:

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.

Since gtkmm 2.6:

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 file chooser, by changing to the URI's parent folder and actually selecting the URI in the list.

If the chooser is Gtk::FILE_CHOOSER_ACTION_SAVE mode, the URI's base name will also appear in the dialog's file name entry.

Note that the URI must exist, or nothing will be done except for the directory change.

You should use this function only when implementing a `File/Save As...` dialog for which you already have a file name to which the user may save. For example, whenthe user opens an existing file and then does `File/Save As...` on it to save a copy or a modified version. If you don't have a file name already — for example, if the user just created a new file and is saving it for the first time, do not call this function. Instead, use something similar to this:

[C example ellipted]

In the first case, the file chooser will present the user with useful suggestions as to where to save his new file. In the second case, the file's existing location is already known, so the file chooser will use it.

Since gtkmm 2.4:

Parameters

  uri | The URI to set as current.

Returns
  Not useful.

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()

Since gtkmm 2.4:

Parameters

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

Glib::SignalProxy0< FileChooserConfirmation > Gtk::FileChooser::signal_confirm_overwrite | ( |  | ) |

Slot Prototype:
  `FileChooserConfirmation on_my_confirm_overwrite()`

This signal gets emitted whenever it is appropriate to present a confirmation dialog when the user has selected a file name that already exists. The signal only gets emitted when the file chooser is in Gtk::FILE_CHOOSER_ACTION_SAVE mode.

Most applications just need to turn on the Gtk::FileChooser::property_do_overwrite_confirmation() property (or call the Gtk::FileChooser::set_do_overwrite_confirmation() function), and they will automatically get a stock confirmation dialog. Applications which need to customize this behavior should do that, and also connect to the Gtk::FileChooser::signal_confirm_overwrite() signal.

A signal handler for this signal must return a Gtk::FileChooserConfirmation value, which indicates the action to take. If the handler determines that the user wants to select a different filename, it should return Gtk::FILE_CHOOSER_CONFIRMATION_SELECT_AGAIN. If it determines that the user is satisfied with his choice of file name, it should return Gtk::FILE_CHOOSER_CONFIRMATION_ACCEPT_FILENAME. On the other hand, if it determines that the stock confirmation dialog should be used, it should return Gtk::FILE_CHOOSER_CONFIRMATION_CONFIRM. The following example illustrates this. <title>Custom confirmation</title>

static GtkFileChooserConfirmation confirm_overwrite_callback (GtkFileChooser *chooser, gpointer data) { char *uri;

uri = gtk_file_chooser_get_uri (chooser);

if (is_uri_read_only (uri)) { if (user_wants_to_replace_read_only_file (uri)) return GTK_FILE_CHOOSER_CONFIRMATION_ACCEPT_FILENAME; else return GTK_FILE_CHOOSER_CONFIRMATION_SELECT_AGAIN; } else return GTK_FILE_CHOOSER_CONFIRMATION_CONFIRM; // fall back to the default dialog }

...

chooser = gtk_file_chooser_dialog_new (...);

gtk_file_chooser_set_do_overwrite_confirmation (GTK_FILE_CHOOSER (dialog), `true`); g_signal_connect (chooser, "confirm-overwrite", G_CALLBACK (confirm_overwrite_callback), `0`);

if (gtk_dialog_run (chooser) == GTK_RESPONSE_ACCEPT) save_to_file (gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (chooser));

gtk_widget_destroy (chooser);

Since gtkmm 2.8:

Returns
  A Gtk::FileChooserConfirmation value that indicates which action to take after emitting the signal.

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

Slot Prototype:
  `void on_my_current_folder_changed()`

This signal is emitted when the current folder in a Gtk::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: Gtk::FileChooser::set_current_folder(), Gtk::FileChooser::get_current_folder(), Gtk::FileChooser::set_current_folder_uri(), Gtk::FileChooser::get_current_folder_uri().

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

Slot Prototype:
  `void on_my_file_activated()`

This 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 Gtk::FileChooserDialog to know when to activate the default button in the dialog.

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

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

Slot Prototype:
  `void on_my_selection_changed()`

This signal is emitted when there is a change in the set of selected files in a Gtk::FileChooser. 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: Gtk::FileChooser::select_filename(), Gtk::FileChooser::unselect_filename(), Gtk::FileChooser::get_filename(), Gtk::FileChooser::get_filenames(), Gtk::FileChooser::select_uri(), Gtk::FileChooser::unselect_uri(), Gtk::FileChooser::get_uri(), Gtk::FileChooser::get_uris().

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

Slot Prototype:
  `void on_my_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 Gtk::FileChooser::set_preview_widget(), you should update it when this signal is emitted. You can use the functions Gtk::FileChooser::get_preview_filename() or Gtk::FileChooser::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 callback must call Gtk::FileChooser::set_preview_widget_active() to inform the file chooser about whether the preview was generated successfully or not.

Please see the example code in <xref linkend="gtkfilechooser-preview">.

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