Cancel a drag operation
int PhCancelDrag(
PhRid_t rid,
unsigned input_group,
unsigned flags );
- rid
- A PhRid_t that must match the
rid passed to the PhInitDrag() that initiated
the drag operation you want to cancel.
- flags
- Must be 0.
- input_group
- An input-group value that must match the input_group
passed to the PhInitDrag() that initiated the drag operation
you want to cancel.
ph
This function cancels a drag. The application still collects a
Ph_EV_DRAG event with a subtype of PhEV_DRAG_COMPLETE
that describes the results of the operation. You can inspect the
button_state member of the event
PhDragEvent_t data structure
to determine whether the PhCancelDrag() call or a button
release caused the operation to complete.
- >0
- Successful completion.
- -1
- An error occurred.
