  • Method Details

    • run

      void run(String path)

      Emitted when the user asks for it.

      This is a keybinding signal.

      This is used to make the file chooser show a "Location" prompt which the user can use to manually type the name of the file he wishes to select.

      The default bindings for this signal are Control-L with a path string of "" (the empty string). It is also bound to / with a path string of "/" (a slash): this lets you type / and immediately type a path name. On Unix systems, this is bound to ~ (tilde) with a path string of "~" itself for access to home directories.
