Justification for Header different to resto column in TListView?

[Ian Branch 127]

Hi Team,

I have a TListview that currently looks like this.

I have tried to set the first column to Center justify but it keeps reverting to Left Justify. 😞

What I would like is for the first column to be center justified, and the second colmn's header to be center but the rest of column to be right.

I would also like the Header font to be Bold as well, but there doesn't appear to be any 'Font' related property.  😞

Is this doable?

If so, how please?

 

Regards & TIA,

Ian

Just create first column without caption and set its width to 0.

The others do what you want to do.

procedure TForm1.Button1Click(Sender: TObject);
var
  MyListColumn: TListColumn;
  MyListItem  : TListItem;
begin
  ListView1.Columns.Clear;
  ListView1.ViewStyle := TViewStyle.vsReport;
  //
  MyListColumn           := ListView1.Columns.Add; // 0
  MyListColumn.Width     := 150;
  MyListColumn.Alignment := TAlignment.taLeftJustify; // alignment of the leftmost column is always LVCFMT_LEFT
  MyListColumn.Caption   := 'LeftJustify';
  MyListColumn.Width     := 0; // a "hack"
  //
  MyListColumn           := ListView1.Columns.Add; // 1
  MyListColumn.Width     := 150;
  MyListColumn.Alignment := TAlignment.taCenter;
  MyListColumn.Caption   := 'CenterJustify';
  //
  MyListColumn           := ListView1.Columns.Add; // 2
  MyListColumn.Width     := 150;
  MyListColumn.Alignment := TAlignment.taRightJustify;
  MyListColumn.Caption   := 'RightJustify';
  //
  MyListColumn           := ListView1.Columns.Add; // 3
  MyListColumn.Width     := 150;
  MyListColumn.Alignment := TAlignment.taCenter;
  MyListColumn.Caption   := 'CenterJustify';
  //
  // 4 columns:  0, 1, 2, 3:
  MyListItem               := ListView1.Items.Add;
  MyListItem.Caption       := 'Item1';     // Column 0
  MyListItem.SubItems.Text := 'SubItem1';  // Column 1
  MyListItem.SubItems.Add('SubItem1.1');   // Column 2
  MyListItem.SubItems.Add('SubItem1.1.1'); // Column 3
end;

Hi p2k.

Unfortunate.  It offends my OCD.  😉

Alignment of the column header and the subitem text in the column. The alignment of the leftmost column is always LVCFMT_LEFT; it cannot be changed. This member can be a combination of the following values. Note that not all combinations are valid.

Your "hack"

All of that is not needed, just do it in the Object Inspector like I told.
