handover 'property references' to JavaScript?
-
Hi together,
does anybody has an idea how to get something like this working?
property int test; onTestChanged: console.log("Awesome!!!") // pseudo callback caller Component.onCompleted: callbackHandler(test); function callbackHandler(prop) { prop = 42; // now I expect "Aawesome" output. }
Is there a way to handover property references to java script functions?
I would like to register a callback to a third party JavaScript library running in QML JS Engine. I know, that this isn't the qtest way to get things running, but in this case it's kind of ... let's call "Case Study" ^^
Thank you very much in advance!

If you pass an object, rather than an int, it's a reference:
property var test: ({ value: 1 }) Component.onCompleted: { console.log(test.value); // prints 1 callback(test); console.log(test.value); // prints 42 } function callback(prop) { prop.value = 42; }
Unfortunately, no "changed" signal is emitted by "var" properties, so you can't have an onChanged handler.
