Hello Guy's,
While building my Qt application I am getting the following error.
Your kind suggestions are welcome.Starting E:\QtCreaterPro\QtCppQml2\debug\QtCppQml2.exe...
QML debugging is enabled. Only use this in a safe environment.
QQmlApplicationEngine failed to load component
qrc:/qml/res/layouts/main.qml:5 Expected type name.I am uploading my code , please refer it for further clarification.
#include <QtGui/QGuiApplication> #include "qtquick2applicationviewer.h" #include <QQmlApplicationEngine> #include <QQmlContext> #include "datastore.h" #include <QtQml> int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); // QtQuick2ApplicationViewer viewer; // viewer.setMainQmlFile(QStringLiteral("qml/QtCppQml2/main.qml")); // viewer.showExpanded(); QQmlApplicationEngine engine; QQmlContext* context = engine.rootContext(); Datastore dt; context->setContextProperty("dataStore",&dt); engine.load(QUrl(QStringLiteral("qrc:/qml/res/layouts/main.qml"))); // engine.load(QUrl::fromLocalFile("qml/QtCppQml2/main.qml")); return app.exec(); }

@Suraj26254 So according to the code at line no.5 it should be
Window
rather thanwindow
. Note: QML types should begin with captial letters. -
@Suraj26254 What is at line no. 5 in
main.qml
? -

@Suraj26254 Seem's like your root component has unknown type or bad name.
Check that imports contains type of root component and type name don't start with e.g. '_' symbol. -
@p3c0 Thanks for replying. Below is the code of main.qml.
//your code here `import QtQuick 2.0 import QtQuick.Window 2.0 import QtQuick.Controls 1.0 window { visible: true width: 100 height: 62 Connections{ target: dataStore onIncreaeOne:txtCount.text.ms } Text{ id: txtCount text: "0 Hits" } Button{ id: btnUpdate anchors.top: txtCount.bottom onClicked: dataStore.callMeFromQml() } }

@Suraj26254

@Suraj26254
