How to make a modal so that it leaves an active minimize button?

Question

C++ / C#

C++ Builder 2009
A modal window opens from the main form via ShowModal(). In this case, the buttons in the main form Collapse, Expand, Close do not work. Is there any way I can set this button to work in a modal window?

Answer 1

That's why it's a modal window, it doesn't allow access to the parent. You can do this by opening a non-modal window.
