I suspect part of your problem might be that the hierarchy for TSpeedButton
is different from TButton. TSpeedButton's immediate superclass is
TGraphicControl whereas for TButton it is TWinControl.
To have a help context, as far as I can see your control has to be
TWinControl or its subclass - TGraphicControl doesn't have a HelpContext
property so there is no built in mechanism for either TGraphicControl or any
descendant (such as TSpeedButton) to implement a HelpContext property (no
inherited handlers). BTW, a TForm is a subclass of TWinControl.
I prefer instead of using TSpeedButton to use TToolbar97Button which has
most of the missing properties (not the tab stop though)
