How can I create Buttons at run-time?

1.

  Start a new application.

 

2.

  Double-click the OnCreate event of your form:

 

void __fastcall TForm1::FormCreate(TObject *Sender)

{

    TButton *Buttons[5];

    for(int x = 0; x < 5; x++)< 5; x++)

    {

        Buttons[x] = new TButton(this);

        Buttons[x]->Parent = this;

        Buttons[x]->Left = 35;

        Buttons[x]->Width = 50;

        Buttons[x]->Height = 30;

        Buttons[x]->Top = (x + 1) * 35;

        Buttons[x]->Caption = IntToStr(x + 1);

    }

}

 

Freeing Components?

 

- When one component owns another, the memory for the owned component is freed when its owner's memory is freed. This means that when the main form is destroyed, all Buttons on the form are also destroyed.
