Description

TCloseEvent is the type of a FireMonkey form's OnClose event handler.

The TCloseEvent type points to a method that handles the closing of a FireMonkey form. The Sender parameter is the form that the user tried to close. The Action parameter returns the action you want the form to take when it closes.

Setting Action controls how the form responds to the attempt to close it, as shown below:

Value	Meaning
caNone	The form is not allowed to close, so nothing happens.
caHide	The form is not closed, but just hidden. Your application can still access a hidden form.
caFree	The form is closed and all allocated memory for the form is freed.
caMinimize	The form is minimized, rather than closed.
