touch detection for desktop QT

[KestrelAdrian]

The detection of whether or not touch support is enabled is always decided by the library, it would be ideal if the touch detection could be overridden such that you could have Auto, Disabled or Enabled to touch support.

I have just replaced google maps in a piece of desktop software with openstreetmap and leaflet. We use Qt with the built in Webkit browser, but the webkit browser that Qt build has "ontouchstart" in the document model, even on the desktop. This has the effect that the sloppy map doesn't work.

I have fixed this by always returning false in the touch function, but it would be convenient if this could be done programmatically rather than having to modify the original code.

+1, I also just recently ran into this issue on a new project using Qt...

Sorry for a late response, I'll try to figure this out for 0.4 release. I'm wondering if there's any way to detect desktop QT so that you didn't need to override the touch setting...

Adde L_NO_TOUCH global variable switch which you can set to true before Leaflet inclusion to force disabling it. Hope this helps.

Fantasic. Sorry for the even later response, but yes, a global switch is definitely the way this should have been implemented.

I could foresee situations where you may want touch detection enabled on the desktop, i.e a kiosk application that uses a touch screen - so automatic detection of Desktop Qt would have given grief in this situation.

Thanks for the update.
