stackView.push() does not recognize item

dhb285

I am failing to pass an item to stackView.push(). i have looked at the following and tried all the described options, but all failed:

http://doc.qt.io/qt-5/qml-qtquick-controls-stackview.html

Here are my simple files:

QmlBackbone.qml:

import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Dialogs 1.2

ApplicationWindow {
    visible: true
    width: 800
    height: 480
    StackView{
        id: stackView
        width: parent.width
        height: parent.height
        initialItem: MainView {}
    }
}

MainView.qml:

import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Dialogs 1.2

Component {
    id: mainView

    Column {
        spacing: 2
        width: parent.width
        height: parent.height
        Rectangle { color: "red"; width: parent.width; height: parent.height/2
                Label {
                    width: parent.width
                    wrapMode: Label.Wrap
                    horizontalAlignment: Qt.AlignHCenter
                    text: "Testing."
                }
        }
        Rectangle { color: "green"; width: parent.width; height: parent.height/2
            Label {
                width: parent.width
                wrapMode: Label.Wrap
                horizontalAlignment: Qt.AlignHCenter
                text: "Settings"
            }
            MouseArea{
                anchors.fill: parent
                onClicked: stackView.push(settingView)
            }
        }
    }
}

SettingView.qml:

import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Dialogs 1.2

Component {
    id: settingView
//    width: parent.width
//    height: parent.height

    Column {
        spacing: 2
        width: parent.width
        height: parent.height
        Rectangle { color: "red"; width: parent.width; height: parent.height/4
                Label {
                    width: parent.width
                    wrapMode: Label.Wrap
                    horizontalAlignment: Qt.AlignHCenter
                    text: "Height."
                }
        }
        Rectangle { color: "green"; width: parent.width; height: parent.height/4
            Label {
                width: parent.width
                wrapMode: Label.Wrap
                horizontalAlignment: Qt.AlignHCenter
                text: "Plot."
            }
        }
        Rectangle { color: "blue"; width: parent.width; height: parent.height/4
            Label {
                width: parent.width
                wrapMode: Label.Wrap
                horizontalAlignment: Qt.AlignHCenter
                text: "Note."
            }
        }
        Rectangle { color: "orange"; width: parent.width; height: parent.height/4
            Label {
                width: parent.width
                wrapMode: Label.Wrap
                horizontalAlignment: Qt.AlignHCenter
                text: "Back."
            }
        }

    }
}

The problem is in the onClicked method of the Settings rectangle of the MainView.
How is that possible and how to solve that problem? All files are in the same folder. I have tried all methods described in the link, I have tried putting the url within QUrl() method, and I have tried methods found elsewhere on the Internet. All of them failed.

Incidentally, I cannot see any error messages at all neither within QTCreater, which I use to write the qml files, nor in Eclipse (PyDev), which I use to write the PyQt surrounding code. Why does that happen and how to fix that?

Thank you in advance.

Hi @dhb285,

the problem is, that you do not instantiate your SettingView.

To solve it, you should make 2 little changes:

Remove the following line from SettingView.qml:

    id: settingView

Add an instance of SettingView to your StackView (as you did with MainView):

    StackView{
        ...
        initialItem: MainView {}
        SettingView { id: settingView }
        ...

But I cannot tell why you can't see errors in QtCreator, when I run your code I get the following message in the Application Output:

qrc:/MainView.qml:29: ReferenceError: settingView is not defined
