I made an MDI application, but when I close an MDI Child,
instead of close, the MDI Child is Minimized.
Can anyone tell what can I do to really close this windows.
Thanks.
Best Regards.

Some thing that is funny, is to free the memory of the
window class.
(But this is my method in C, and my brain is the size of a wal(l)nut)

But me(Gonzo) and my friend(Acid Smurf)'s tips is:

procedure Form1Close(Sender : TObject);
begin
   Form1.Visible := False;
end;

Then the user is stupid and believes the window is destroyed.

The user maybe stupid but delphi it isn't. When you try to
hide (visible := False) an MDI Child the following message
appears: Can't Hide an MDI Child.
Thanks for gonzo's help anyway.

This code actally closes the MDI child form.  Use in the FormClose Event.

procedure TChildForm.FormClose (Sender: TObject;
  Var Action: TCloseAction);
Begin
  Action := caFree;
end;

That's it. Call the form's Close actions as you normally would via a button or menu item and the MDI Child actually closes instead of minimizes.

Any questions, please add a coment.

Good Luck!
