Issue created Feb 14, 2020 by Andrea Veri@averiOwner

Have a widget for zoomable/pannable viewers

Currently apps have to do it manually, and it's tricky and none of them get it 100% correct. We could have a scrolled window+container widget that would handle pan and zoom for all the different device types automatically and just expose pan/zoom signals.

Some things it should handle:

  • Scrolling with mouse scrolls
  • Dragging with mouse pans
  • Scrolling with touchpad/touchscreen pans
  • Pinch zoom zooms
  • Ctrl+touchpad scroll still zooms as a fallback
  • Whatever else that I forgot
