Struct gtk4::FileDialog

#[repr(transparent)]
pub struct FileDialog { /* private fields */ }

Available on crate feature v4_10 only.

A FileDialog object collects the arguments that are needed to present a file chooser dialog to the user, such as a title for the dialog and whether it should be modal.

The dialog is shown with open(), save(), etc. These APIs follow the GIO async pattern, and the result can be obtained by calling the corresponding finish function, for example Gtk::FileDialog::open_finish().

Properties

accept-label

Label for the file chooser’s accept button.

Readable | Writeable

default-filter

The default filter, that is, the filter that is initially active in the file chooser dialog.

If the default filter is None, the first filter of filters is used as the default filter. If that property contains no filter, the dialog will be unfiltered.

If filters is not None, the default filter should be part of the list. If it is not, the dialog may choose to not make it available.

Readable | Writeable

filters

The list of filters.

See default-filter about how those two properties interact.

Readable | Writeable

initial-file

The initial file, that is, the file that is initially selected in the file chooser dialog

This is a utility property that sets both initial-folder and initial-name.

Readable | Writeable

initial-folder

The initial folder, that is, the directory that is initially opened in the file chooser dialog

Readable | Writeable

initial-name

The initial name, that is, the filename that is initially selected in the file chooser dialog.

Readable | Writeable

modal

Whether the file chooser dialog is modal.

Readable | Writeable

title

A title that may be shown on the file chooser dialog.

pub fn open<P: FnOnce(Result<File, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

This function initiates a file selection operation by presenting a file chooser dialog to the user.

The @callback will be called when the dialog is dismissed. It should call Gtk::FileDialog::open_finish() to obtain the result.

parent

the parent Window

cancellable

a GCancellable to cancel the operation

callback

a callback to call when the operation is complete

pub fn open_future( &self, parent: Option<&(impl IsA<Window> + Clone + 'static)> ) -> Pin<Box_<dyn Future<Output = Result<File, Error>> + 'static>>

This function initiates a multi-file selection operation by presenting a file chooser dialog to the user.

The file chooser will initially be opened in the directory initial-folder.

The @callback will be called when the dialog is dismissed. It should call Gtk::FileDialog::open_multiple_finish() to obtain the result.

This function initiates a file save operation by presenting a file chooser dialog to the user.

The @callback will be called when the dialog is dismissed. It should call Gtk::FileDialog::save_finish() to obtain the result.

This function initiates a directory selection operation by presenting a file chooser dialog to the user.

If you pass @initial_folder, the file chooser will initially be opened in the parent directory of that folder, otherwise, it will be in the directory initial-folder.

The @callback will be called when the dialog is dismissed. It should call Gtk::FileDialog::select_folder_finish() to obtain the result.

parent

the parent Window

cancellable

a GCancellable to cancel the operation

callback

a callback to call when the operation is complete

pub fn select_folder_future( &self, parent: Option<&(impl IsA<Window> + Clone + 'static)> ) -> Pin<Box_<dyn Future<Output = Result<File, Error>> + 'static>>

pub fn select_multiple_folders<P: FnOnce(Result<Option<ListModel>, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P )

This function initiates a multi-directory selection operation by presenting a file chooser dialog to the user.

The file chooser will initially be opened in the directory initial-folder.

The @callback will be called when the dialog is dismissed. It should call Gtk::FileDialog::select_multiple_folders_finish() to obtain the result.

pub fn set_accept_label(&self, accept_label: Option<&str>)

Sets the label shown on the file chooser’s accept button.

Leaving the accept label unset or setting it as NULL will fall back to a default label, depending on what API is used to launch the file dialog.

accept_label

the new accept label

pub fn set_default_filter(&self, filter: Option<&FileFilter>)

Sets the filter that will be selected by default in the file chooser dialog.

If set to None, the first item in filters will be used as the default filter. If that list is empty, the dialog will be unfiltered.

filter

pub fn set_filters(&self, filters: Option<&impl IsA<ListModel>>)

Sets the filters that will be offered to the user in the file chooser dialog.

pub fn set_initial_file(&self, file: Option<&impl IsA<File>>)

Sets the file that will be initially selected in the file chooser dialog.

This function is a shortcut for calling both gtk_file_dialog_set_initial_folder() and gtk_file_dialog_set_initial_name() with the directory and name of @file respectively.
