    I have a QML / Qt Application which loads a .qml file several times, with different models.

    But before loading the file the second time the Application closes the first.

    So my question is how do I load a qml file several times without closing anything ?

      hi
      @RLocksley said in Loading qml file several times without closing:

      How do you load the file exactly ?
      Are you using a the Loader type ? Can you show a minimal example to explain your issue ?

        Thanks for your fast reply.

        Below is the frontend code of a minimal example of my problem.

        main.qml

        import QtQuick 2.12
        import QtQuick.Window 2.12
        import QtQuick.Controls 2.12
        Window {
            visible: true
            width: 640
            height: 480
            title: qsTr("ConnectionList")
        
        
            ListView {
                anchors.fill: parent
                model: models["list"].length
        
                delegate: Text {
                    id: chatPartner
                    text: models["list"][index]
        
                    MouseArea {
                        anchors.fill: parent
                        onClicked: { appCore.receiveChatPartner( chatPartner.text ) }
                    }
                }
            }
        
        
        
            Connections {
                target: appCore
                onSendModel:{
                    chatLoader.setSource( "qrc:/Chat.qml", { "a_model": _model } )
                   
                }
            }
                Loader {
                            anchors.fill: parent

                        }
        
        }
        

        chat.qml

        import QtQuick 2.0

            title: "ChatWindow"
            
            property string a_model
        
            ListView {
                anchors.fill: parent
                model: models[a_model].length

          So you want to open Chat.qml (window) multiple times ?
          You can't do it with the loader, it loads only one Component at the time
          try to create your windows dynamically
