Description
I've been working on a tree based task management app in druid that has a component which allows placing and moving of widgets on an infinite canvas. It looks something like this:
This works great modulo some performance issues, but I can't figure out how to implement zooming of the canvas. I've seen some requests and suggestions that such a thing should exist, but I haven't seen any suggestions for how it should be implemented. I'm guessing it would require modifying of events before passing them to child widgets and some trickery with the paint context.
I'm interested in working on such features. Does anybody here have any suggestions for how to get started on such a thing?
