Sl_dragx()                                                         XCONTROL

Syntax

VOID (*xcpb->Sl_dragx)( tree, base, slider, min, max, numvar, foo )
OBJECT *tree;
WORD base, slider, min, max;
WORD *numvar;
VOID (*foo)();

Function      Sl_dragx() is called by a CPX when a user clicks on the
              horizontal slider 'elevator' of an 'active' slider.

Parameters    tree points to an OBJECT tree containing the slider
              elements. base is the object index of the slider 'track'.
              slider is the object index of the slider 'elevator'.
              min specifies the minimum value the slider can represent.
              max specifies the maximum value the slider can represent.
              numvar points to a WORD containing the value which the slider
              represents and which is to be updated as the slider is
              moved. foo points to a user-defined routine which is called
              each time the slider value numvar is modified. foo may be
              NULL if no updating is desired.

Binding       (*xcpb->Sl_dragx)( tree, base, slider, min, max,
                                 numvar, foo );

Comments      It is appropriate to change the shape of the mouse to
              FLAT_HAND while the user is dragging a slider.
