Good Evening!

I have constructed a large array of TEdit objects for a graphical interface
application and I am having some trouble adding in EventHandlers using code
rather than the Object Editor.

The code i have to call the event, onChange is below with <problem
parameters> filled in for the part I am unable to resolve:

box_array[i]->OnChange(<problem parameters>);

The suggested parameter is given as: void TEdit::OnChange(_fastcall *
(_closure)(TObject *))(TObject *)

If, for example I have an event handler function called ColorChange(), how
would I call this OnChange function such that the Edit box would go to the
function ColorChange during the appropriate event?

Thanks!
Scott
