Bangle 2 menu and event questions.

How do you terminate events in Bangle 2? Here's the problem I'm having...

var menu = {
	"" : {
		"title" : " Menu Test"
	},
	"Do Nothing" : function() {},
	"Close Menu" : function() {
		E.showMenu();
	}
};

Bangle.on('touch', function(n,ev) {
	E.showMenu(menu);
});

g.clear();
E.showMenu(menu);

After closing the menu there, a tap on the screen opens it again. However, if you tap where the "Close Menu" choice was, the menu promptly closes again. What's the best fix for this?

In https://github.com/espruino/BangleApps/blob/fb7b69379a61d70bdde176837533e67cd2f6b288/apps/drinkcounter/app.js#L239 I'm checking the coordinates of the touch. Maybe that would be an approach.

I think you only need to remove the touch listener that you introduced on line 11. See my answer on another thread.

I first learnt that here.

EDIT: And here's the documentation.

Many thanks for the replies. @thyttan put me on the right track with listeners. Here's the working code...

var menu = {
	"" : {
		"title" : " Menu Test"
	},
	"Do Nothing" : function() {},
	"Close Menu" : function() {
		E.showMenu();
		Bangle.on('touch', screenTouch);
	}
};

function screenTouch() {
	Bangle.removeListener("touch", screenTouch);
	E.showMenu(menu);
}

g.clear();
E.showMenu(menu);
