Implementing more and more touch events into “TosmE” by coding each separately got difficult. I thought about a touch-gesture-recognition module. A web search presented a lot of ready to use solutions.

One of them was Dojo. Dojo is also used by the upcoming JavaScript editor iD. So I read some tutorials and tried to realize the features of TosmE with DoJo. Well, it wasn’t easy. I missed an Index how to solve certain functions. And I missed examples. So my soluton was cartainly ugly but it worked so far. I could set new nodes and move them.

But the Dojo modules dojo/mouse dojox/gesture don’t support all the extras I did with plain JavaScript. I differ between steady and moved object untouching for example. I wanted a Z-like gesture for undo. And so on.

That’s no dead end, Dojo is ought to be extended. At last, I learned a lot about event driven coding instead of time cycles. There are other frameworks with much more features. This looks fine. iD is extendig to other frameworks to, we will see.
