The event ptrDrag occurs when the pointer is being moved while at least one pointer button is depressed.
Information about the position of the pointer and about the pointer-button(s) pressed can be obtained using the macros %%EvPtrButton, %%EvPtrPos and %%EvPtrState.
For a Scroll Bar component, this
is achieved by holding down the pointer button while moving the pointer over
the position indicator.
Hint: action logic for the event ptrDown
is typically related to dragging activity.
Any other action logic is often more appropriate when the
event ptrUp occurs.
See also the event ptrMove.
In MWAPI, this event is called "PDRAG".
