Public Member Functions

void StartDragBox (Spread *pSpread, DocCoord Anchor, ClickModifiers)
 Deals with a single click situation (i.e. no drag occurred).
virtual void DragFinished (DocCoord, ClickModifiers, Spread *, BOOL, BOOL bSolidDrag)
 This is called when a drag operation finishes. This removes the EORed drag rect from the screen and then selects all the objects that were in it. It then goes through these objects, selecting all other objects sharing a name with any of them.

Static Public Member Functions

static BOOL Declare ()
 Adds the operation to the list of all known operations.
static OpState GetState (String_256 *Description, OpDescriptor *)
 Find out the state of the operation at the specific time.
