Create Simple qml application

Question

I am new to Qt. I am creating simple qml application. Qt Version :- QMake version 2.01a Using Qt version 4.6.2 I am on Linux system. I have created qml containing two buttons(button.qml) and also created c++ code(main.cpp).

Code for main.cpp

 #include<QtGui/QApplication>
 #include<QtGui/QLabel>
 #include"qmlapplicationviewer.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QmlApplicationViewer viewer;

    viewer.setOrientation(QmlApplicationViewer::ScreenOrientationLockLandscape);   
    viewer.setMainQmlFile(QLatin1String("button.qml"));
    viewer.showExpanded();
    a.exec();
}

I am compiling it with qmake && make and got error as

qmlapplicationviewer.h: No such file or directory
QmlApplicationViewerâ was not declared in this scope

I tried to search for "qmlapplicationviewer.h" and "QmlApplicationViewer" on my system. But unable to find it.

Please help.

Answer 1

I would not use the application viewer for such a simple case, so I would drop it. I would write something like this:

#include <QDeclarativeView>
#include <QApplication>

int main(int argc, char **argv)
{
    QApplication app( argc, argv );

    QDeclarativeView view;
    view.setSource(QUrl("button.qml"));
    view.showFullScreen();

    return app.exec();
}

If you really wish to use the qml application viewer, you could obtain the header and source file from here , and add them to the corresponding HEADERS and SOURCES variables in your project file.
