Dialog QML open passing variable

marco_88

Hi. I made a dialog about QML that works, but I have some small problems. It must be outside the listView, but I must show text from the ListView model in the Dialog. In the onClicked of the MouseArea from which I open the dialog if I write this text in console.log that I want to display, I display it, so how can I pass this information to the dialog that I want to open to display it in there?
Thanks

Hi Marco,

I am a beginner but from what I found it is not possible to pass on a variable. What I did in your case is to use a "global" variable. With the button click I write the index of the clicked element to a variable that is accessible to the dialog. In the dialog I read in the element on the visible changed.

ListView {
  id: dataView
  property int activeIndex: 0

  delegate: Rectangle {
    [...]
    Button {
       onClicked: activeIndex = index    
    }
  }
}

Dialog {
  onVisibleChanged: {
     var element = dataView.model.get(dataView.activeIndex)
  }
}

Hope that still helps =)

@D_Tec Couldn't you introduce a property in the Dialog and assign the required value to it before you open the dialog?

hi,

@D_Tec said in Dialog QML open passing variable:

var element = dataView.model.get(dataView.activeIndex)

this will probably not work, activeIndex is just a property of the listview, it is not part of the model
you should access it using the list id

 var element = dataView.activeIndex

you can access to the model directly using get() method

    Component.onCompleted: {dataView.model.insert(0, {"age" : 100})}
    ListView {
        id: dataView
        model: ListModel{}
    }
  // dataView.model.get(0).age

This code works for me. My dialogs contain the information from the model that I want when they are opened. I do not see where the difference is to @LeLev. Where you put your information on which item the user clicked does not matter.

@Bob64 I do not know how access your dialogs but I guess you can assign a property and access it with dialogId.propertyName.

@D_Tec "I guess you can assign a property and access it with dialogId.propertyName"

Yes, exactly.
