Struct dialog::FileSelection

pub struct FileSelection { /* fields omitted */ }

A file chooser dialog box.

This dialog box opens a file choser with an optional title in the specified path. If the path is not specified, it defaults to the user’s home directory.

The backends might support multiple operation modes, for example open or save dialogs. You can select a mode using the FileSelectionMode enum, though the backend might ignore the mode and just display a simple file dialog. Per default, the mode is set to Open.

Example

use dialog::DialogBox;

let choice = dialog::FileSelection::new("Please select a file")
    .title("File Selection")
    .path("/home/user/Downloads")
    .show()
    .expect("Could not display dialog box");
println!("The user chose: {:?}", choice);
