问题:

Is is possible to change the item selection focus color and text color in a TListBox?

When themes are not enabled in the project, or the list box style is set to owner-draw, the selection around the item is painted blue, which I believe is globally defined by the system's appearance settings.

I would like to change the color of selected items to a custom color.

So an example, the result would be something like this:

Note the last listbox has been modified in Paint to illustrate the example.

try this:

procedure TForm1.ListBox1DrawItem(Control: TWinControl; Index: Integer;
  Rect: TRect; State: TOwnerDrawState);
begin
  with (Control as TListBox).Canvas do
  begin
    if odSelected in State then
      Brush.Color := $00FFD2A6;

    FillRect(Rect);
    TextOut(Rect.Left, Rect.Top, (Control as TListBox).Items[Index]);
    if odFocused In State then begin
      Brush.Color := ListBox1.Color;
      DrawFocusRect(Rect);
    end;
  end;
end;
