I have implemented touch scroll for WPF version of CefSharp.
My first attempt was to use SendMouseWheelEvent, but this stops working at some point after navigation, click on buttons, select item in dropdown....
I generally use now javascript window.scrollBy() function. Mostly it works fine, but with some websites not, for ex.: https://www13.state.nj.us/DataMiner
The scrollbar is displayed and i can manually scroll, also touch scroll works in cefclient.exe... but scrollBy has no effect, SendMouseWheelEvent also does not work.
The scrollBy function does not work in IE, FireFox and Chrome for this sample website. I guess they have some javascript hack or strange CSS styles which makes the srollBy function not working.
scrollBy does not work at all when a PDF is displayed, SendMouseWheelEvent scrolls the PDF down, but not up.
It would be great if you can add a scroll method to CEF.
