How to run multiple QML workerscript at the same time












0















I have set multiple worker script in QML like this.



WorkerScript{
id:worker1
source: "PostWorker.js"
onMessage: {
textArea1.text= textArea1.text + messageObject.reply + "n"
}
}


worker1, worker2, worker3, and worker 4. At the same time, also have 4 TextArea; textArea1, textArea2, textArea3, and TextArea4. written Like so.



        ScrollView {
id: view1
width: root.width*0.22
height: root.height*0.95

TextArea {
id:textArea1
text: ""
}
}


and lastly is a function that runs upon start



function post(){
var chunks = createGroupedArray(studentList,studentList.length/4)
worker1.sendMessage()
worker2.sendMessage()
worker3.sendMessage()
worker4.sendMessage()
console.log("exited function")
}


The PostWorker.js script will run and will each loop 1000 times and do some calculations and will send a message back to textArea,



What happens is it will wait for the first worker to finish its 1000loops before the second worker starts. How would i make it that they would all start simultaneously.



I know that the 4 workers are triggered since console shows the "exited function"
