How to Custom Paint Data Cells

In the example, only selected data cells are custom painted. For the required result, the following settings have been specified: the tree list’s OptionsSelection.CellSelect property is True, and the OptionsSelection.InvertSelect property is False.
// Delphi

else
begin
//paint the focused node
ACanvas.Brush.Color := $80FFFF;
end;
end;
This is the code execution result:
