[question]

Hi,
I have another question

I have created one form which has he following attributes:
type
TForm1 = class(TForm)
btnEnter: TButton;
btnDisplay: TButton;
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
procedure btnEnterClick(Sender: TObject);
procedure btnDisplayClick(Sender: TObject);
I have another form form2 which has its own button, but I would like to inherit the form1 into form2, but I don’t want to inherit the complete form1 ,just few functionality,such as ( btnEnter: TButton; procedure btnEnterClick(Sender: TObject) ), but I don’t have idea ,how to inherit a form partially.
Do you have any suggestion please?

Hi,

create a third unit with the button methods/procedure/actions.
This unit can then be used in form1 and form2.

Basicaly split functional things from user-interface.
