Mouse wheel

[sannaide]

Hi there! I'm looking at code, in pointer event how can i know if a wheel mouse event occurred? If yes, can i distinguish if is wheel up or down?
Thanks in advance

I'm not quite sure what you're asking but mouse wheel events are handled here: https://github.com/any1/wayvnc/blob/master/src/pointer.c#L38-L70

Aa ok thanks. how can i use that code in main.c? i remember on_pointer_event there, but i see only x and y coordinates in that function...

The parameter is called button_mask. It's a bitmap of pressed buttons. See https://github.com/any1/neatvnc/blob/master/include/neatvnc.h#L30-L36 and https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#pointerevent

I see...ok I think I can write some code in on_pointer_event() to distinguish from wheel up and down. Thanks!
