Glib::RefPtr< Gtk::FileChooser > wrap (GtkFileChooser* object, bool take_copy=false)
 A Glib::wrap() method for this object.

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.

Member Function Documentation

void Gtk::FileChooser::add_filter ( const 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 Glib::ustring &  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.

Returns:
true if both the folder could be changed and the URI was selected successfully, false otherwise.
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 Glib::ustring &  filename  ) 

Sets the current folder for chooser from a local filename.

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.

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.

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.

Regardless of this setting, the chooser will emit the Gtk::FileChooser::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::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 > &  uri  ) 

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 <guimenuitem>File/Save As...</guimenuitem> 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 <guimenuitem>File/Save As...</guimenuitem> 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: |[ if (document_is_new) { / * the user just created a new document * / gtk_file_chooser_set_current_folder_file (chooser, default_file_for_saving); gtk_file_chooser_set_current_name (chooser, "Untitled document"); } else { / * the user edited an existing document * / gtk_file_chooser_set_file (chooser, existing_file); } ]|

Since gtkmm 2.14:
Parameters:
file The File to set as current.
Returns:
true if both the folder could be changed and the file was selected successfully, false otherwise.
bool Gtk::FileChooser::set_filename ( const Glib::ustring &  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.

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 <guimenuitem>File/Save As...</guimenuitem> 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 <guimenuitem>File/Save As...</guimenuitem> 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: |[ if (document_is_new) { / * the user just created a new document * / gtk_file_chooser_set_current_folder (chooser, default_folder_for_saving); gtk_file_chooser_set_current_name (chooser, "Untitled document"); } else { / * the user edited an existing document * / gtk_file_chooser_set_filename (chooser, existing_filename); } ]|

Since gtkmm 2.4:
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.

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(),

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::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.

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.

If the URI 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 URI must exist, or nothing will be done except for the directory change. If you are implementing a <guimenuitem>File/Save As...</guimenuitem> 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 <guimenuitem>File/Save As...</guimenuitem> 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: |[ if (document_is_new) { / * the user just created a new document * / gtk_file_chooser_set_current_folder_uri (chooser, default_folder_for_saving); gtk_file_chooser_set_current_name (chooser, "Untitled document"); } else { / * the user edited an existing document * / gtk_file_chooser_set_uri (chooser, existing_uri); } ]|

Since gtkmm 2.4:
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()

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 (  ) 
Prototype:
FileChooserConfirmation on_my_confirm_overwrite()
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().
Prototype:
void on_my_current_folder_changed()
Glib::SignalProxy0< void > Gtk::FileChooser::signal_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 FileChooserDialog to know when to activate the default button in the dialog.

See also:
get_filename(), get_filenames(), get_uri(), get_uris().
Prototype:
void on_my_file_activated()
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().
Prototype:
void on_my_selection_changed()
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().
Prototype:
void on_my_update_preview()
void Gtk::FileChooser::unselect_all (  )

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

Since gtkmm 2.14:
Parameters:
file A File.
void Gtk::FileChooser::unselect_filename ( const Glib::ustring &  filename  )
