PhCancelDrag()
Cancel a drag operation
Synopsis:
int PhCancelDrag(
PhRid_t rid,
unsigned input_group,
unsigned flags );
Arguments:
- 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.
Library:
ph
Description:
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.
Returns:
- >0
- Successful completion.
- -1
- An error occurred.
