* use that message for messages from MSWHEEL.
|
||
|
|
* LKM May 1996 - Added add'l #defines for class and title of the wheel
|
||
|
|
* module window to reflect the MSH_ style.
|
||
|
|
* - Added #defines for WHEEL SUPPORT and Scroll Lines
|
||
|
|
* - Added inline function HwndMsWheel, apps can use
|
||
|
|
* this function to retrieve the handle to mswheel,
|
||
|
|
* get the message ID's for the registered messages,
|
||
|
|
* the flag for 3d support, and the value for scroll
|
||
|
|
* lines. Please in function at end of file.
