 |

Hello!
I created new component based on TDBEdit1 and I wanted to modify standard
OnKeyPress event. So, below there is my code in which the compiler returned
an
error:
class PACKAGE bTDBEdit1 : public TDBEdit1
{
private:
protected:
void __fastcall KeyPress();
public:
__fastcall (TComponent* Owner);
__published:
__property OnKeyPress;
};
void __fastcall bTDBEdit1::KeyPress()
{
TDBEdit1::KeyPress(); // perform standard handling, including
calling handler
// your customizations go here
}
Thx in advance
Borut

the proper declaration is:
DYNAMIC void __fastcall KeyPress(char &Key);

Still error.
class PACKAGE bTDBEdit1 : public TDBEdit
{
private:
protected:
DYNAMIC void __fastcall KeyPress(char &Key);
public:
__fastcall bTDBEdit1(TComponent* Owner);
__published:
__property OnKeyPress;
default=true};
};
void __fastcall bTDBEdit1::KeyPress()
{
TDBEdit::KeyPress(); // perform standard handling, including
calling handler
// your customizations go here
}
ERROR:
[C++ Error] bTDBEdit1.cpp(13): E2316 '_fastcall bTDBEdit1::KeyPress()' is
not a member of 'bTDBEdit1'
?????

This function has an argument, key, which you omitted. You are
calling the inherited function here, so the argument is required.

You forgot the arg to KeyPress(char& Key).
Exactly what Tim said.

You don't need to republish this. It is already published in TDBEdit.
