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?
