How to handle widget showing E.showMessage with the watchface?

So, my watchface shows the seconds using setTimeout. I noticed that it will still redraw them even if a widget shows an E.showMessage above it. How do I handle that? Can I check for it somehow and then temporarily stop the timeout?

Which widget is this? Widgets really shouldn't do that because it will definitely break things - all the default ones load up a new app to avoid that kind of problem. There's also the notify library that basically does that for you.

But if you added a remove handler to setUI like this: http://www.espruino.com/Bangle.js+Fast+Load

Then that would solve the problem, because showMessage would call the remove handler. But then after the message was gone you'd be left with nothing.

... and if the widget was running for pretty much any other app, that would break too - so I wouldn't recommend it

It is https://github.com/espruino/BangleApps/tree/master/apps/widbt_notify

In https://github.com/espruino/BangleApps/blob/master/apps/hworldclock/app.js I got the remove handler.

Ahh, ok. Yes, widbt_notify is a bit of a disaster.

It should really use setOverlay now IMO - fixing that would really be the best bet
