Pass data between GUIs without eval function

Hi all,

I've got a few GUIs working together, which should share information.

One of the GUIs has around 40 variables created, which must be used in other scripts/GUIs for data processing (Struct creation). I know is not good to use eval or global, however I don't really want to call a function with 40 inputs and 10-20 outputs 'cause I think it's ugly...

I know I could send and receive the variablels from the workspace by using Assignin(...), but is there any other easy/optimum way to do it??

Thank you!

How are the GUIs created? Programatically, GUIDE, or App-designer? How about creating a handle class and passing its instance between GUIs. If one app changes a variable, all the other GUIs can automatically access new values.

The standard, easy, and efficient approach is to store a structure in the UserData field of groot:

I recommend writing your own GUI code and avoiding GUIDE.

Hi both, thank you for the answers.

I´ve created the GUIs using guide, which makes everything much easier. I've never tried programatrically tbh.

I'll have a look at both solutions and let you know if I have more problems, thank you!!

For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread.
