All Access

No restrictions. Generally, your gadget code should use the correct accessor functions like any other form object. However, in a gadget callback function, your code needs to have direct access to the gadget's structure fields. Emulator makes no distinction for whether the access in the callback function, so the structure access is not restricted. Your application should still access gadgets using the correct accessor functions whenever possible.
