Appearance for PDListBox

[Bharat Bhatt]

Hi,

I want to change the appearance of drop down list (PDListBox). How to use
different font, font size and color of text?
I tried using following code
            String defaultAppearanceString = "/Helv 12 Tf 0 0 0 rg";
           PDListBox.setDefaultAppearance(defaultAppearanceString);

Please let me know what will be better approach?
