I have a parameter which is accesible through a edit field. I would like this parameter to also be accessible in another tab. Is it possible to somehow link two edit fields or make a second instance of the same edit field?

Hi, you can use a callback on the first edit field (ValueChangedFcn). In this callback function, you simple assign the new value to the target edit field value.

Hi. Thanks for the answer. Ill probably do what you suggested. The problem is that it scales badly. What if i want 3 edit fields. Then i have to create at least 4 callbacks to make sure all fields are in agreement.
It just seems like a feature that could be generally usefull.

Yes, I see your point. There might be a possibility to link directly properties of you objects using linkprop. But actually I'm not sure if this is possible for app components. I have used it for axes properties though and it worked fine.
