Hi Kay,

Thanks for the prompt response.

I indeed tried saving as a memento file and loaded as you suggest, but it doesn't seem to work and I get the following.
2021-03-26 17:19:42 WARNING [org.phoebus.ui.application.PhoebusApplication] Ignoring launch parameter '-layout'
2021-03-26 17:19:42 WARNING [org.phoebus.ui.application.PhoebusApplication] Ignoring launch parameter '/home/user/opi/simple.memento'

Am I missing something here? I ran it as:
./phoebus.sh -layout /home/user/opi/simple.memento

I wasn't aware of this - thanks for sharing - it looks useful. I will take a further look.

In an interactive session, open the desired display(s).
Maybe use the "Window" menu to hide toolbar and status bar, and maybe select the full-screen mode.
Use Window, Save Layout As .. to save that layout.
By default, it will end in a file $HOME/.phoebus/NameOfLayout.memento, for details see https://control-system-studio.readthedocs.io/en/latest/locations.html

From now on you can start phoebus with the 
    -layout /path/to/Example.memento
option to open that saved layout.

You can include the JVM in your package.
The example launch scripts look for "../jdk".
The SNS-specific packages use that.



BUT: That's a large package to download, just to offer you users with a crippled read-only screen.

Have you looked at the display builder web runtime, https://github.com/kasemir/dbwr?
That allows your users to see (by default: read only) displays in a web browser.
There are some limitations to what you can do in that display, mostly: No scripts, but many screens will "just work" with zero installation effort on the user end.

Subject: [EXTERNAL] Phoebus lock down BOB 
 
Dear,
 
I have a Display builder (.bob) file which I would like to "lock down" in the sense that I can provide a stand-alone application just showing this OPI without the ability to edit or play with it, and hide from the user that it is CS-Studio/Phoebus.
 
Ideally I would just like to ship a single binary which can be loaded by a user (given the have the JVM) and they see a simple read-only screen.
 
I am sure this is possible to do, I just am struggling to find any documentation or examples on how to do this.
 
I've been trying things like this with no success:
./phoebus.sh -resource file:/home/user/opi/simple.bob?app=display_runtime
 
Any pointers or advice on this would be much appreciated.
 
Kind regards,
Tom
