TRadioGroup.Items Property

Lists the radio buttons in the radio group.

Pascal

property Items: TStrings;

C++

__property TStrings Items;

Description

Items holds a TStrings object that lists the captions of the radio buttons in the group. In TCustomRadioGroup descendants, where this property is published, radio buttons can be added or removed by editing the Items list from the Object Inspector.

Note: A TRadioButton object is created automatically for each string in Items. You cannot directly add or remove TRadioButton objects, but you can access individual TButton objects through the Buttons property.

C++ Examples:

Copy Code

/*
This example uses a radio group box and a scroll bar on a
form. When the user selects one of the radio buttons, the
scroll bar changes orientation accordingly.
*/
void __fastcall TForm1::FormCreate(TObject *Sender)
{
  RadioGroup1->Items->Add("Vertical");
  RadioGroup1->Items->Add("Horizontal");
  RadioGroup1->ItemIndex = 2;
}

void __fastcall TForm1::RadioGroup1Click(TObject *Sender)
{
  if (RadioGroup1->Items->Strings[RadioGroup1->ItemIndex] == "Vertical")
    ScrollBar1->Kind = sbVertical;
  else if (RadioGroup1->Items->Strings[RadioGroup1->ItemIndex] == "Horizontal")
    ScrollBar1->Kind = sbHorizontal;
}

Delphi Examples:

Copy Code

{
This example uses a radio group box and a scroll bar on a
form. When the user selects one of the radio buttons, the
scroll bar changes orientation accordingly.
}
procedure TForm1.FormCreate(Sender: TObject);
begin
  RadioGroup1.Items.Add('Vertical');
  RadioGroup1.Items.Add('Horizontal');
  RadioGroup1.ItemIndex := 2;
end;

procedure TForm1.RadioGroup1Click(Sender: TObject);
begin
  if RadioGroup1.Items[RadioGroup1.ItemIndex] = 'Vertical' then
    ScrollBar1.Kind := sbVertical;
  if RadioGroup1.Items[RadioGroup1.ItemIndex] = 'Horizontal' then
    ScrollBar1.Kind := sbHorizontal;
end;
