External Shared Class?

I can see when you right click (windows) on a class you can make it external which I assume means that I can then add that external class to another project but I cant see how I add it to the other projects I have?

drag it in
if you look in the user guide it lists how you can import it as external into other projects as well

I have grouped together a load of classes I have created under a module called “nwcToolbox” but Xojo is not allowing me to make the module external. Do I have to make each class external and then create a new module called “nwcToolbox” in all my projects and drag the classes themselves into the new project?

Use a folder instead of a module.

You can then export the folder with all the classes within.

Ah ok, thanks.
