It is possible to create more than one MDI form in a delphi application?

I developed a mdi application that has in its main form several child windows that are created at runtime. The 开发者_如何学Cchild windows are custom forms. I want to display those custom forms in another form from the same application. Is this possible?

No, that is not possible using standard VCL. Only the application's MainForm can be the MDI Form. But it should be possible by using win32 directly as shown here.

I don't believe this is possible in the VCL. As I understand it the MDI form is assumed to be the main form (Application.MainForm). I imagine the underlying Windows routines will not have any such assumption, but I think the VCL will not let you do this without some serious hacking.

At various points in the VCL framework, the important MDI messages are sent to Application.MainForm.ClientHandle. Now, ClientHandle is the MDI container, but for some reason the container for the main form has been singled out.
