I remember doing it in Delphi 7, but I don't remember how, or in the new Delphi IDE. But how do you add a new template to the item gallery?
So, it will appear in the File / New menu .
Jim, try Project β "Add to Repository ..."
If I remember correctly, from the loaded project you would do "add to repository" in the "Project" menu. From there, you will select your page where it should appear.
In the help, if you're looking for "Template Libraries", it gives instructions on how to do this.
