Handle WM_MOUSEHWHEEL for horizontal touchpad scrolling #30

Closed mdonatas closed 1 year ago

mdonatas commented 1 year ago

It turns out that Panel on which this editor is based only handles WM_MOUSEWHEEL which gives vertical scrolling but doesn't handle WM_MOUSEHWHEEL which is fired during horizontal scroll. So I basically copy/pasted this code used for vertical scrolling and hooked it up to vertical scroll events. Methods in Win32Util also came from there.

Testing methodology

Manual testing with laptop-touchpad

p.s. I've also created a simple Form with a Panel and some oversized content in both x and y axises and confirmed that horizontal scrolling with touch-pad doesn't work image
