  • Method Details

    • run

      void run(int bookmarkIndex)

      Emitted when the user asks for it.

      This is a keybinding signal.

      This is used to make the file chooser switch to the bookmark specified in the bookmarkIndex parameter. For example, if you have three bookmarks, you can pass 0, 1, 2 to this signal to switch to each of them, respectively.

      The default binding for this signal is Alt-1, Alt-2, etc. until Alt-0. Note that in the default binding, that Alt-1 is actually defined to switch to the bookmark at index 0, and so on successively.
