Hi Marcus,

you could add an event handler to the Grasshopper window focus event, or you could add an event handler to the file itself. So that whenever the file changes, Grasshopper responds. In fact there is a synchronize option on the File parameter which does just this. So if you use a File parameter instead of a Text Panel, enable the Synchronize option and you should already be getting automatic updates.

If you want to know how to handle the Grasshopper focus event instead (though I can't type it in python, it'll have to be C# or VB) I can try and explain that too.

I thought "File Path" is just a container for file names.

It is. But it also has the synchronization build in and it can expire parameters that depend on it whenever the file changes.
