virtual BOOL Init ()
 PointersTab initialisation routine.
virtual BOOL HandleMsg (DialogMsg *Msg)
 Handles all the Edit options tabs messages.
virtual BOOL InitSection ()
 Sets initial values for the Pointers section of the options dialog box. This section includes the:-
  • magnetic snap distances
  • click modifier lists.

virtual BOOL CommitSection ()
 Takes the values in the Pointers section tab of the options dialog box and sets the associated preference values accordingly Called when ok is pressed on the dialog box. Middle button removed for now as nothing seems to use it.
virtual BOOL GreySection ()
 Called when the user has closed all documents.
virtual BOOL UngreySection ()
 Called when the user has selected a new document.
BOOL ChangeControlStatus (const BOOL Status)
 Called to grey/ungrey all controls on this tab.
virtual BOOL UpdateSection (String_256 *DocumentName)
