Egui::SystemPorts::PickFolderDialog
Class methods
show(title : String = "Choose folder", directory : String | Nil = nil, &on_done : String | Nil -> ) : Nil
Start a non-blocking pick-a-DIRECTORY dialog. Returns
immediately; on_done receives the chosen folder path, or nil
on cancel / when no dialog tool is available, on a later frame.
Same async contract as OpenFileDialog.show.
- title — dialog window title.
- directory — where the dialog starts.
