No, we cannot do that since there's no property in GtkFrame to do such thing.
Under gtk2 TPanel is scrolling control because GtkFrame is wrong class  (wrong 
gtk design IMO).There should be pure GtkFrame (like it is eg under qt) and 
GtkGroupBox (which is current GtkFrame).
Only way to fix this is to write an gtk2lcl class which should be like qt's 
QFrame , and of course use that class instead of scolling controls.
