Macro bind_keys

macro_rules! bind_keys {
    ($file_dialog:expr, $e:expr) => { ... };
}

Macro to automatically overwrite the default key bindings of the app, when the file dialog is open.

This macro only works inside of a function that returns a std::io::Result or a result that has an error type that implements From<std::io::Error>.

Default bindings:

Key	Action
q, Esc	Close the file dialog.
j, Down	Move down in the file list.
k, Up	Move up in the file list.
Enter	Select the current item.
u	Move one directory up.
I	Toggle showing hidden files.

Example

bind_keys!(
    // Expression to use to access the file dialog.
    app.file_dialog,
    // Event handler of the app, when the file dialog is closed.
    if let Event::Key(key) = event::read()? {
        match key.code {
            KeyCode::Char('q') => {
                return Ok(());
            }
            _ => {}
        }
    }
)
