without using a 3rd party component, is there a simple way to color the text in TListBox, TComboBox, TStringGrid ans TTreeView?

If not color, maybe I could just use bold/italic, etc.  Ideally I would like 4 colours, but could live with being able to distinguish 2.

The simpler the solution, the better.

Thanks, but if I need to use 3 party components, I will use something from http://www.tmssoftware.com

However, I would strongly prefer to do it wthout 3rd party compnents if possible.

sure, it's from borland, but it is listing 3rd party components, nor Borland components.

As far as I know, it is not possible to do what I am asking with the standard compenents.

I am 99% sure, but just want to see if anyone knows better. If it can't be done, then I will use the TMS components, which are free and can do what I want to do.

Create an event handler for the listbox's OnDrawItem event, and put code like this in it:

    TCanvas *pCanvas = ((TListBox *)Control)->Canvas;
    if (((TListBox *)Control)->Items->Strings[Index]=="Red")
        pCanvas->Font->Color=clRed;
    else if (((TListBox *)Control)->ItemIndex==Index) {
        pCanvas->Font->Color=clHighlightText;
    else
        pCanvas->Font->Color=clWindowText;

    pCanvas->FillRect(Rect);
    pCanvas->TextOut(Rect.Left,Rect.Top,
         ((TListBox *)Control)->Items->Strings[Index]);


This code will display the listbox normally, except that any item with the text "Red" will be colored red.  You can adjust the if statements to suit your needs, of course, but you should leave the last two if you have any items you don't want special behavior for.
