EDGE button

HI,

For EDGE devices with touch screen....

We are developing a data field and we would like to add a button on screen to show certain info via pop up. Is it possible?

Thanks in advance,

thanks a lot, but I think I too dumb I put this onUpdate and does not work, do I have to do something else?

it shows me this error

		if(val) {
		Model = 1;
		}else{
		Model = 2;
		}

Ok I have this working

	class InputDelegate extends Ui.BehaviorDelegate {
	function onTap(evt) {
		var val = !val;
    	Ui.requestUpdate();
    	return true;
    }
    }
    
    function initialize() {
        DataField.initialize();
        BehaviorDelegate.initialize();
        }
        
    function onUpdate(dc) {

		if(val == true) {
		Model = 1;
		}else{
		Model = 2;
		}

but val is not detected

Undefined symbol ':val' detected.

if you want val to be in your input delegate, after line 1 for what you posted, add

var val=false; //or =true;, depending on what you want the default to be.

no, it does not work it says it also does not work if you put var val = true; inside: class AppView extends Ui.DataField {

Cannot find symbol ':val' on type 'self' on the line 16.

the problem I think it's inside onUpdate

no it think it's not posible get out a variable to onUpdate I also tried to call with a delegate .mc this way but it says

Undefined symbol ':val' detected.

using Toybox.WatchUi;

class AppDataFieldDelegate extends WatchUi.BehaviorDelegate {
  function initialize() {
    BehaviorDelegate.initialize();
  }

  function onTap(event) {
    var val = true;
    WatchUi.requestUpdate();
    return true;
  } 
}

        class AppView extends Ui.DataField {
        
        var del = new AppDataFieldDelegate();
        }

        function onUpdate(dc) {
		if(del.val) {
		Model = 1;
		}else{
		Model = 2;
		}
		}

In getInitial view, bothe the view and delegate are created. What you can do is pass the view to the delegate (or v/v) like this:

function getInitialView() {

var view=new MyView();

return [view,MyDelegate(view)];

}

in your delegate, ininialize will have the view as a parameter

class MyDelegate extends WatchUi.BehaviorDelegate {
  var view;
  function initialize(v) {
    BehaviorDelegate.initialize();
    view=v;
  }
  
  function onTap(evt) {
    view.val=!view.val;
    WatchUi.requestUpdate();
    return true;
  }
}

var val is then in your view class, but it's changed in the delegate.

if I wish to this onKey what should I do I think this is not ok

    function onKey(evt) {
    	var key=evt.getKey();
	if(key==WatchUi.KEY_ENTER) {
   	val = !val;
   	}
   	WatchUi.requestUpdate();
	return true;
	}
	}
