Synchronize dolphin file view with terminal (when using tmux)

I sometimes use dolphin together with a terminal. Key is that the directory shown in Dolphin is synchronized with the current directory in the terminal. So when I cd in the terminal, the view in dolphin should change.

A while ago I started to use tmux within console, for various reasons. Since then, the synchronization does no longer work.

This got me wondering:

  • How is Dolphin notified about directory changed in the terminal?

  • Is there a way to manually trigger this change from the terminal?

  • Is the a way to make this automatically happen when using tmux, at least when there is just one pane?
