TRzListBox Add Item to Group

[Barry Wood]

Hi

I have a TRzListBox setup with 2 headings: ‘Players’ and ‘Reserves’. During the application a User can add a new Player or Reserve.

How do I add this new player to the ‘Players’ section? When I simply clList.Add( cNewName ) it goes to the bottom of the list.

Hi Barry,

You can use the AddItemToGroup method. For example, the following code adds a couple groups and items to the list. Then in the button click event handler, a new player is added to the first group. Changing the first parameter to a 1 will add Ian to the Reserves group.

Ray

procedure TForm8.FormCreate(Sender: TObject);
begin
  RzListBox1.ShowGroups := True;
  RzListBox1.AddGroup( 'Players' );
  RzListBox1.Add( 'Anthony Rizzo' );
  RzListBox1.Add( 'Kris Bryant' );
  RzListBox1.Add( 'Javier Baez' );
  RzListBox1.AddGroup( 'Reserves' );
  RzListBox1.Add( 'Albert Almora Jr.' );
end;

procedure TForm8.RzButton1Click(Sender: TObject);
begin
  RzListBox1.AddItemToGroup( 0, 'Ian Happ' );
end;

Ray,

Many thanks, as ever. I’m building up a list of ‘simple’ examples of how to use your controls ‘properly’, so one day I won’t need to ask you 🙂
