Re: Do Google Web Toolkit's touch events support Windows tablets?

2020-08-19 Thread Craig Mitchell 
I had a lot of problems with touch events.  However, they weren't GWT's 
fault, just different browsers doing different things.

I ended up with this:
// Listen for the screen touch start
mainPanel.addDomHandler(event -> {
handleScreenTouches(event.getChangedTouches(), true);
}, TouchStartEvent.getType());

// Listen for the screen touch move
mainPanel.addDomHandler(event -> {
handleScreenTouches(event.getChangedTouches(), true);
}, TouchMoveEvent.getType());

// Listen for the screen touch end
mainPanel.addDomHandler(event -> {
handleScreenTouches(event.getChangedTouches(), false);
}, TouchEndEvent.getType());

And then kept my own array of what touches are occurring.

I'm not sure if it works fine with a surface pro.  You can try if you like  
https://drift.team/  if the game controls work fine (especially with multi 
touch), then all good.

 Hi all. Currently working on a webapp using GWT. I currently have a 
 feature working with touch events on a Canvas. The feature itself works 
 perfectly fine on every device but windows tablets (surface pro). Is there 
 something special I have to do for this, or does GWT have no way of doing 
 this?

Re: Do Google Web Toolkit's touch events support Windows tablets?

2020-07-28 Thread Paul French 
When I looked at this 6 years ago (in relation to MGWT, which is dead
although we still use it in legacy products) Pointer events were the way to
go and are supported on all browsers now as far as I am aware.

There was talk of a single touch/pointer API system in GWT similar to what
MGWT did where it took mouse, touch and pointer events and converted to a
single touch event system. Hence you coded to MGWT's touch system and it
worked on all devices.

No idea if GWT did this in the end.

I assume you are using an old IE Edge? Latest Edge uses webkit under the
hood and so your problems may go away with this browser. Older IE Edge as
far as I can remember does not support touch events but does support
Pointer events.

Take what I say with a pinch of salt. It has been many years but I believe
that is why you have an issue.

Maybe you can Google for : JS surface touch events
Or something like that. But for JS. Maybe that can point you in the right 
direction.

2020-07-27 Thread Michael Conrad 
you will need to check and see what event is actually generated for the
windows 10 tablet in the dom and hook those.
