## class

```cpp
   struct FontProp_t {
      TString     fName;               // font name
      Int_t       fSize;               // font size

      Pixel_t     fColor;              // text color
      Bool_t      fBold;               // bold flag
      Bool_t      fItalic;             // italic flag
