If you want to use the word inherited in CPB, you have to write a typedef for it. For authors not coming from Delphi, it's more common just to write the name of the class. But you could write your code like this. Note in each case that most of the lines were written by the IDE: Header: typedef TCustomGrid inherited; class PACKAGE TMGrid : public TStringGrid { private: protected: public: __fastcall TMGrid(TComponent* Owner); void __fastcall MoveRow( int FromIndex, int ToIndex ); __published: }; Code File: __fastcall TMGrid::TMGrid(TComponent* Owner) : TStringGrid(Owner) { } void __fastcall TMGrid::MoveRow( int FromIndex, int ToIndex ) { inherited::MoveRow( FromIndex, ToIndex ); } -- Timothy H.

Doing this will allow you to redefine inherited in other files without conflicts.... -- chris Back to top Remy Lebeau (TeamB) Guest Posted: Fri Nov 21, 2003 8:36 pm    Post subject: Re: Syntax errors - simple component "JD" <nospam (AT) nospam (DOT) com> wrote Quote: I want to install a StringGrid decendant to the pallette but I'm getting compile errors. May I have some help please? You are trying to declare functions inside of other functions. You can't do that. You are supposed to declare your new methods in the header file and them implement them separately in the .cpp file. Do not try to do everything inside the constructor code. For example: --- MGrid.h --- #ifndef MGridH #define MGridH //-------------------------------------------------------------- #include <SysUtils.hpp> #include <Classes.hpp> #include <Controls.hpp> #include <Grids.hpp> //-------------------------------------------------------------- class PACKAGE TMGrid : public TStringGrid { typedef TStringGrid inherited; private: protected: public: __fastcall TMGrid(TComponent* Owner); void __fastcall MoveRow( int FromIndex, int ToIndex ); void __fastcall InsertRow( int Index ); void __fastcall DeleteRow( int Index ); __published: }; //-------------------------------------------------------------- #endif --- MGrid.cpp --- //-------------------------------------------------------------- #include <vcl.h> #pragma hdrstop #include "MGrid.h" #pragma package(smart_init) //-------------------------------------------------------------- static inline void ValidCtrCheck(TMGrid *) { new TMGrid(NULL); } //-------------------------------------------------------------- __fastcall TMGrid::TMGrid(TComponent* Owner) : TStringGrid(Owner) { } //-------------------------------------------------------------- void __fastcall TMGrid::MoveRow( int FromIndex, int ToIndex ) { inherited::MoveRow( FromIndex, ToIndex ); } //-------------------------------------------------------------- void __fastcall TMGrid::InsertRow( int Index ) { // this statement will not work // ++RowCount; RowCount = RowCount + 1; inherited::MoveRow( RowCount - 1, Index ); } //-------------------------------------------------------------- void __fastcall TMGrid::DeleteRow( int Index ) { inherited::DeleteRow( Index ); } //-------------------------------------------------------------- namespace Mgrid { void __fastcall PACKAGE Register() { TComponentClass classes[1] = {__classid(TMGrid)}; RegisterComponents("IDEAtum", classes, 0); } } //-------------------------------------------------------------- Gambit Back to top JD Guest Posted: Sun Nov 23, 2003 9:44 am    Post subject: Re: Syntax errors - simple component "Remy Lebeau (TeamB)" <gambit47.no.spam (AT) no (DOT) spam.yahoo.com> wrote: Quote: [...] For example: Thanks for the help. I did manage to get most of it but I was stuck with the typedef for inherited. Using TCustomGrid kept causing a compiler error but it's handled and on my palette.
