Dear experts,

I have a question , this option is always expanded every time I start Slicer.

In fact, I don’t use this option often, so I need to close it manually every time.

Is there a way to change the unexpanded state as the default.

Any scripts?

As is shown in this picture.

You can use the method `setDataProbeVisible`. See here for more details

> slicer.util has this function: which you can use with detecting when your module is entered/exited to hide the data probe. This can be done by defining the enter() / exit() functions in your module. See:

as part of the application startup script
