How do I draw the selected list-box item in a different color?


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.


Solution

  • 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;
