I haven't used XE2 yet, still using RAD studio 2010. Nevertheless, the following works for me:
- Go to the Design View of your new form.
- Select the form from the Structure tree ( or just click on it ).
- Change the name property of the form.
That should then change the class and class-pointer names of the unit.
Can't see why that wouldn't work in XE and later versions, but as I mentioned - not tested.
Update: Verified method works for C++ Builder 10.1 Berlin.
