I was using a TStringGrid to show some data but I need the "non-linear multi-select" from TListView.
However, the tricks to set Brush color inside of OnCustomDraw or OnAdvancedCustomDraw do not work.
Am I missing something? How is it done?

Try using the PrepareCanvas event.

Something loke:

procedure TArpDatForm.SG1PrepareCanvas(sender: TObject; aCol, aRow: Integer;
  aState: TGridDrawState);
Var
  St:String;
begin
  SG1.Canvas.brush.color := clWhite;
  If aCol = 4 Then
  Begin
    St := SG1.Cells[4,arow];
    St := Copy(St,1,pos('.',st)-1);
    If (SG1.Cells[3,aRow]  St) Then
    Begin
      SG1.Canvas.Brush.color := clRed;
    end;
  End;
end;

However, the tricks to set Brush color inside of OnCustomDraw or OnAdvancedCustomDraw do not work. Am I missing something? How is it done?

You cannot do that.
And even if you get it working with one widgetset, it would fail on any other OS, since they all draw it differently.

I ended up writing my own list view
(http://www.benibela.de/components_en.html#treelistview), just to get differently colored rows

Or you can stay with the grid and implement your own selection (http://www.lazarus.freepascal.org/index.php?topic=7981.0)

May we use your component on a proprietary software?

Good question.

Not unconditonally for all of them, that's why it's gpled

But at least if it benefits humanity, you can just go ahead and use it...

I'm using treelistview from Benibela (GTK2). I have some questions:
- How to set the SelectedFont background color? SelectedFont.Color sets only the "pen" color, not the "brush" color
- How to use the OnCustomRecordItemDraw to set a line's background color depending on its content ?
