Hi,

Is there a possibility to lock (ex. show some window text box on the screen) dashboard screen when somebody else is using it actually ( connected from diffrent IP)?

Thank you in advance for help,

Michał,

I'm not going to say I know the answer, but there is a way you could do it.

Say you are using the dashboard on _machine1_ which has its own IP address.  
You want to change what someone else sees when they are using another machine.  
(Basically NOT _machine1_ and a different IP address.)

One way is that you give them a link to a different screen than the one you use/see.  
This will also mean you need to edit what is shown in the _menu_ list (top left) of the GUI screen.

Then, unless they know the exact name of the other screens: they are pretty well stuck looking at that dashboard.

You can use the ui-control node of the dashboard. This sends a message when a new session is created or an existing is closed/loss. When yo keep track on the session ids then you can either send a message to this, all other or all dashboards. Or even make your flow capable of multi sessions.

I misunderstood how ui-control works. Thank you @Christian-Me for pointing me to the solution. I haven't written a working code yet, but I know which way to go. Thanks!
