How to iterate over the MDI child array

Answer:

The documentation of TForm.MDIChildren[] states that the index of the first-created 
MDI child is 0. This is incorrect - the index of the most-recently-created MDI 
child is always 0, and the index of the first-created MDI child is always 
MDIChildCount - 1. With this in mind, you can use the following code to iterate 
over the MDI child array from from the first-created to the last:


1   procedure TForm1.IterateOverMDIChildren;
2   var
3     i: integer;
4   begin
5     for i := MDIChildCount - 1 downto 0 do
6     begin
7       {do something with MDI child here}
8     end;
9   end;
