Description

This example uses an edit box and a memo control on a form. When either the edit box or the memo is the active control, it is colored yellow. When the active control becomes inactive, the color of the control returns to the Windows system color for a window. These event handlers could also be shared.

Code

void __fastcall TForm1::Edit1Enter(TObject *Sender)
{
  Edit1->Color = clYellow;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Edit1Exit(TObject *Sender)
{
  Edit1->Color = clWindow;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Memo1Enter(TObject *Sender)
{
  Memo1->Color = clYellow;
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Memo1Exit(TObject *Sender)
{
  Memo1->Color = clWindow;
}
