QtQuick structure

[codeman]

Hello friends,

I am a little bit confused about the structure of an qml app.

How can I export QObject to my app written in qml:

import QtQuick 2.1
import QtQuick.Controls 1.0
import QtQuick.Layouts 1.0
import QtQuick.Window 2.0
 
ApplicationWindow {
    width: 640
    height: 480
 
    menuBar: MenuBar {
        Menu {
            title: qsTr("File")
            MenuItem {
                text: qsTr("Exit")
                onTriggered: Qt.quit();
            }
        }
    }
statusBar: StatusBar{
        Text{
            anchors.centerIn: parent
            text: "Ready"
            font.family: "Verdana"
        }
    }
}

import QtQuick 2.1
import QtQuick.Controls 1.0
import QtQuick.Layouts 1.0
import QtQuick.Window 2.0

ApplicationWindow {
    width: 640
    height: 480
    
    menuBar: MenuBar {
        Menu {
            title: qsTr("File")
            MenuItem {
                text: qsTr("Exit")
                onTriggered: Qt.quit();
            }
        }
    }
statusBar: StatusBar{
        Text{
            anchors.centerIn: parent
            text: "Ready"
            font.family: "Verdana"
        }
    }
}

To copy to clipboard, switch view to plain text mode 

The Problem is I cannot imagine how to register my new qobject type without a main.cpp!
Could anybody provide an example project with exporting new c++ types to an app written with

ApplicationWindow {}

ApplicationWindow {}

To copy to clipboard, switch view to plain text mode

If you don't want to have a main.cpp then you need to export all your types as a QML plugin and then import that plugin into your QML code and declare items of types you exported in the plugin. Other than that, you can create a regular application that will create a QQuickView or QQuickWindow, load your QtQuick code and optionally expose everything you want exposed.

Thank you very much. Ok I use the Plugin approach.
But when it comes to running on debug it comes to this error:

The plugin 'C:/Users/xxxxx/xxxxx/xxxxx/xxxx/ProjectRoot/MyPluginPlugin/qmltestplugin.dll' uses incompatible Qt library. (Cannot mix debug and release libraries.)

Compiling debug is not the problem. In release everything is ok.

Compiling debug is not the problem. In release everything is ok.

Hmm... so what's the problem if both are ok?

And seriously, build your plugin in release mode.

I mean compiling in Debug is not the problem, but when I try to run the program it says " (Cannot mix debug and release libraries.)"

In release I can compile and run the program...

Yours,
