Struct gtk4::FileDialog

source ·
pub struct FileDialog { /* private fields */ }
Available on crate feature v4_10 only.
Expand description

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

Whether the file chooser dialog is modal.

Readable | Writeable

§title

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

source

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

source

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 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
