TouchPad scrolling on the latest VMWare Workstation

Question

It's been 8 years since I tried to make scrolling work in VMWare workstation! (Since 2004).
AND it's still not implemented !!
in VirtualBox it works just perfectly, why don't you guys just rip some code off VirtualBox?
check this link:
http://communities.vmware.com/search.jspa?resultTypes=&dateRange=last90days&peopleEnabled=true&q=touchpad+scrolling&containerType=&container=&containerName=&username=&rankBy=30&numResults=30
there are lotsa threads with a similar problem.
I believe this problem should have VERY high priority due very high percentage of users just moving to VirtualBox from VMWare.
*BASIC* scrolling for touchpad is not so hard to implement..

Answer 1

take a look here:
https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Devices/Input/DevPS2.cpp
in particular:
557    /**
558     * Send a single relative packet in 3-byte PS/2 format to the PS/2 controller.
559     * @param  s               keyboard state object
560     * @param  dx              relative X value, must be between -256 and +255
561     * @param  dy              relative y value, must be between -256 and +255
562     * @param  fButtonsLow     the state of the two first mouse buttons
563     * @param  fButtonsPacked  the state of the upper three mouse buttons and
564     *                         scroll wheel movement, packed as per the
565     *                         MOUSE_EXT_* defines.  For standard PS/2 packets
566     *                         only pass the value of button 3 here.
