How to listen to a signal from the initalItem in Stackview QML












0















I want to listen to a signal emitted from the initialItem in QML StackView. And it seems that the way i think on how to do it is wrong.



StackView {
id: stackView
initialItem:{
myHomeForm{
onMySignal{
myArray=signalArray
}
}
}
anchors.fill: parent
}


The documentation only says on how to set a property but none on listening to a signal
Please help thank you very much

          You can make the connection in Component.onCompleted through connect:



          import QtQuick 2.9
          import QtQuick.Controls 2.2

          ApplicationWindow {
          id: window
          visible: true
          width: 640
          height: 480
          title: qsTr("Stack")

          StackView {
          id: stackView
          initialItem: Page {
          id: page
          anchors.fill: parent
          signal mySignal()
          Button {
          text: qsTr("Click me")
          anchors.centerIn: parent
          onClicked: page.mySignal()
          }
          }
          anchors.fill: parent
          Component.onCompleted: initialItem.mySignal.connect(onMySignal)
          function onMySignal(){
          console.log("onMySignal")
          }
          }
          }

          • for future readers. If the signal has attached data the function will be written like this function onMySignal(data){ console.log("onMySignal " + data) }
