- 0 2.0
Checks whether a mouse event was generated by the pen driver.
BOOL IsPenEvent( UINT message, LONG lExtraInfo )
Parameters
message
Windows mouse message being queried.
lExtraInfo
Value returned by GetMessageExtraInfo for the given message.
Return Value
Returns TRUE if the mouse event referenced by the message parameter was generated by the pen driver; otherwise, returns FALSE.
Comments
Mouse drivers that have not been updated to be compatible with pens may
produce an event that cannot be distinguished from a real pen event. This has a very
low probability of occurring.
