i try to use the CHARTEVENT_MOUSE_WHEEL on a new MT4 Build 1170. Confused ist that the MTEditor suggest me the event and the ENUM 'CHART_EVENT_MOUSE_WHEEL' for the ChartSetInteger function. But the ChartSetInteger function return false and GetLastError return 4210 = Unknown Chart Property.
For testing i did the same code run on MT5, there it run successful.
Got anyone an idea if i can use a file/lib or something else from MT5 to get the event run on mt4 ? Or where the events are managed ?
Here is an article of the event https://www.mql5.com/en/docs/constants/chartconstants/enum_chartevents (last part)
