I'm writing a new component in C++ Builder v5.0 but I get the following error when I try to compile the unit,

(C++ Error) myedit.h(42)E2113 Virtual Function '__fastcall TMyEdit::Click()' conflicts with base class TControl.

This is the *.h file

//---------------------------------------------------------#ifndef MyEditH
#define MyEditH
//---------------------------------------------------------#include <SysUtils.hpp>
#include <Controls.hpp>
#include <Classes.hpp>
#include <Forms.hpp>
#include <StdCtrls.hpp>
//---------------------------------------------------------class PACKAGE TMyEdit : public TCustomEdit
{
private:
   TNotifyEvent FOnEnter;
protected:
 
   ************* This where I get the error ************
   void __fastcall DoEnter(void);
   *****************************************************
   __property TNotifyEvent OnEnter = {read=FOnEnter, write=FOnEnter};
public:
__fastcall TMyEdit(TComponent* Owner);
__published:
};
//---------------------------------------------------------#endif


Please give me an example of how to override the OnClick method.

Thanks.

check parameter. Must be something as TObject *Sender:

void __fastcall TForm1::FormClick(TObject *Sender)

And usually use
  Classes::TNotifyEvent OnEnter
....
  __property Classes::TNotifyEvent OnEnter = {read=FOnEnter, write=FOnEnter};
...
And seems me you have error
TNotifyEvent FOnEnter; //must be OnEnter
