elan trackpad can't use?

[MasonTroll]

i'm korean sorry for my bad english.

i'm elan trackpad user.
why elan trackpad cannot be used absolute pointing.
is that hardware problem? or else?

Cannot fix it if it's hardware problem?

AbsoluteTouch uses the Synaptics API to read the touchpad input. As far as I know Elan does not have an API, so this program won't work on Elan touchpads. Sorry.

i'm a student in korea.
i started to learn programming from 2017.3

i'm planning to program absolutetouch on elan trackpad.
is that impossible to develop?
api or hardware problem?

It's definitely possible, but you would need to write a driver for it that runs in the kernel. You can take a look at the Linux driver for Elan touchpads, but getting it to work on Windows will be a difficult task.

Thank you for comment!

I read events from /dev/input/eventX in Linux and successfully got the absolute position.I am wondering if there is any universal method to read events from Win32 API since Windows10 support multi-touch gestures for both Syn and Elan.

Not sure, I'm not familiar with the Windows kernel. I think https://msdn.microsoft.com/en-us/library/windows/desktop/ms645543(v=vs.85).aspx would be the closest thing? Don't know if you can get raw touchpad input from it though.
