Detecting touch displays

[jrheinlaender]

In WeatherRouting.cpp there is code framed by #ifdef __OCPN__ANDROID__ that sets up touch gestures. Wouldn't it be better to use the result of WxWindow::EnableTouchEvents() instead? There can be non-Android platforms that support touch displays.

Yes, possibly. Let me take a look at the code tomorrow and see what we can do about it.

There is also a setting in OpenCPN Display options to enable and disable touch screens. We might need to take a look at how OpenCPN handles this and do something similar. I would guess there are lots of subtleties involved. 😁

It's worth remembering that most of this code (in weather routing) was written 13 years ago, in the very early days of Android, and has not been very actively maintained since then. It's quite possible that at the time, Android was the only supported platform that had a touch screen interface. There might well be a lot of code you find that could do with refreshes like you've suggested.
