I have used the idea to store objects in javascript for global access
before. You have to make sure you have ".pragma library" in the JS file,
though, or you will have each JS import declare it's own name scope. Not
what you want for a global variable :)
The JS file looks something like this:
.pragma library
var globalObject;
function getGlobalObject() {
return globalObject;
}
function setGlobalObject(object) {
return globalObject;
}
In each QML file, you import this one and then you have access to your
object.
I think this is a horrible piece of code, but it's the only way I have
found so far.
If possible, move the shared values you have to a C++ object instead and
declare this as a named global property. This is a cleaner way to access
shared values. But it only works on limited data types.
