Add touch support

[jacobtoye]

Methodology of drawing doesn't work at all for touch browsers :|

• Polylines and ploygons: it is too hard to click on the close marker.
• Rectangles and Markers:drawn by mousedown -> mousemove -> mouseup, this won't work on touch devices.

Hello Jacob,

I'm using your code for a project which I'm currently building for the iPad, so I added some "hacky" touch support. It's not perfect, but works for me. (I'm using it for drawing polygons only so far....) Maybe that could work as a starting point for you. Cheers and thanks for your work!

Awesome! Thanks for that @mphasize. Your code will be a good start. I'll hopefully get the time within the next month of so to add support for the rest of the shapes/markers.

Had some time to do it myself . :-) See https://github.com/jacobtoye/Leaflet.draw/pull/5

+1 is touch polygon drawing on the horizon?

[jacobtoye]

Honestly not at this stage. :(

Alas... I actually have sufficient impetus to work on this today, assume the solution isn't simply a case of binding ~touchClick events then? Before I take a look, are there some design issues I should consider?

[jacobtoye]

Yeah I wish it were that easy :( unfortunately we would need to redo most if the handlers. Check out my responses to the pull request referenced above. Let me know what you think.

Could I possibly request two things if you're not planning to implement this at present? Firstly, could you look at disabling the buttons on mobile devices? Secondly, could you make it clear in your front page on Github that it isn't available on mobile? Just for the sake of clarity, you know...

Both would be much appreciated!

Hi jacobtoye & philipn, first of all, great work!! I'd like to know, if I want iPad support today, what is the easiest hack I can apply?

Thanks!

[jacobtoye]

@thejae your best bet is to check out what this pull was doing and try apply it to a fork. It will be quite a bit of work :(

[thejae]

@jacobtoye Thanks for your reply :) do you accept donations in exchange for feature requests? If yes, what kind of donations are we speaking about for Touch support?

[philipn]

@jacobtoye This plugin is fantastic! I'd also be interested in knowing how much time and money it'd take to complete this work, as we may be able to sponsor a bit.

@philipn @thejae Thanks for the offer guys, however I'm too busy to work on another project.

Unfortunately it wouldn't be as simple as adding some touch handlers to the plugin. The handlers would need to create and edit the shapes differently.
