SetLabelFont(Style_t font=62, Option_t *axis="X");
SetTitleFont(Style_t font=62, Option_t *axis="X"); //set axis title font or pad title
SetStatFont(Style_t font=62) {fStatFont=font;}
The created TPaveText objects can use TStyle settings only if TPaveText class has UseCurrentStyle() method. Unfortunately that is not the case (I did not check before answering your post yesterday, sorry).
