Example: TreeList.CreateColumn, Column.ApplyBestFit

• Jul 30, 2021

The following sample shows how to create columns. The CreateColumns method accepts the following parameters:

AColumns contains captions for new columns. Note that this parameter should be initialized.

ABand represents the band to which the new columns will belong.

Delphi

procedure CreateColumns(AColumns: TStringList; ABand: TcxTreeListBand);
var
  I: Integer;
begin
  for I := 0 to AColumns.Count - 1 do
    with cxTreeList.CreateColumn(ABand) do
      begin
        Caption.Text := AColumns[I];
        ApplyBestFit;
      end;
end;

C++

void __fastcall CreateColumns(TStringList *AColumns, TcxTreeListBand *ABand)
{
 TcxTreeListColumn *AColumn;
 for (int I = 0; I < AColumns->Count; I++) {
     AColumn = cxTreeList->CreateColumn(ABand);
     AColumn->Caption->Text = AColumns->Strings[I];
 }
}
