Problem with inherited class

[jbpelletier]

Here is my problem...
i dont know how i should implement the TSquare class witch is inherited from TShape... i tried different thing but i already have an error in relation with the construtor...


-UMain.cpp------------------
#include "Uboard.h"
.....
TFrmMain *FrmMain;
Board TBoard(FrmMain);
.....

-UBoard.h-----------------
#include "USquare.h"
.....
class TBoard
{
protected:
.....
public:
TBoard(TComponent*); //const : build an array 8*8
//of Tsquare
.....
};

-USquare.h-----------------
class TSquare:TShape
{
protected:
.....
public:
TSquare(??????????); //construtor
.....
};

TSquare::TSquare(???????):TShape(???????)
{
......
}

------------------------------
any help will be apreciate....

jb,

Since this only a skeleton I cannot really tell what you are trying to do, but I think that your problem lies in the definition of the TSquare constructor:

TSquare::TSquare(???????):TShape(???????)
{
......
}


The stuff that follows the ":" in a constructor definition is basically data initialization that is to occur before the body of the constructor is entered. I suspect that your intent is different: you think that you are specifying that TSquare is derived from TShape... that is not at all what this expression means! You have already specified the inheritance in the "class TSquare : TShape" expression...
