This patch include:

– <ParentWindowName>.<GridControlName>.HeaderDYNAMICFONT ( nCol ) := {|| {cFontName, nFontSize, [ lBold,
lItalic, lUnderline, lStrikeOut ]} }
– <ParentWindowName>.<GridControlName>.HeaderDYNAMICFORECOLOR ( nCol ) := {|| aColor }
– <ParentWindowName>.<GridControlName>.HeaderDYNAMICBACKCOLOR ( nCol ) := {|| aColor } // implemented but not work ???

Demo :

#include "hmg.ch"
