Qml doesn't allow javascript singletons?

[patrickkidd]

I appears as though javascript files are executed in a separate context each time they are imported. This appears to make it impossible to store singleton objects at the top-level scope for the file. Is there any way to accomplish this?

Thanks!

I think what you are looking for is pragma Singleton

Thanks, but that is for singleton Qml components not Javascript files.

That was what I was looking for. However, of my 7 or so qml files that import this (all loaded in a different QQuickWidget), the top-level code is still being executed twice. That's better than the 7 times it was executed before, but it should only be executed once. All QQuickWidget instances are using the same QQmlEngine so I'm not sure what's going on here.

executed twice

I did the test couple of days ago and the code in my js file is executed only once.
How do you import the file ?

I import the file from four different qml files, all do this:

import 'js/Global.js' as Global

@patrickkidd can you make a simple project that replicates this behavior ?
