@jsulm
um, should i make something like this?QQuickView view; view.setSource(QUrl::fromLocalFile("C:/qtqml57/main.qml")); view.show();the output is still
file:///C:/qtqml57/main.qml: File not found@Andrey-Shmelew Something like this:
QString path = QCoreApplication::applicationDirPath() + '/' + "main.qml"; QQuickView view; view.setSource(QUrl::fromLocalFile(path)); view.show(); -

thanks, but it don't works for mefile:///usr/main.qml: File not foundnote that when i deploy with qt 5.5 kit it enables to deploy without any path stuff
so if i upload main.qml to beaglebone's /usr/ folder then i get :
QQuickView only supports loading of root objects that derive from QQuickItem. If your example is using QML 2, (such as qmlscene) and the .qml file you loaded has 'import QtQuick 1.0' or 'import Qt 4.7', this error will occur. To load files with 'import QtQuick 1.0' or 'import Qt 4.7', use the QDeclarativeView class in the Qt Quick 1 module. -

Where is you app located? -
@Andrey-Shmelew "/usr"?!
Where is you app located? -
@jsulm
it is located in beaglebone's /usr folder when deployed.When i develop -main.qml is located on windows C:/qtqml57/main.qml ( qtqml57 is qt 5 project folder)
@Andrey-Shmelew Quite unusual location.
Can you describe how the layout of your app is?
Is it like this:/usr/YOUR_APP_EXECUTABLE /usr/main.qml?

@jsulm
by default it is:project:
windows 10, project path C:/qtqml57/
after rebuild it's deployed in Linux /usr/ directory
@Andrey-Shmelew can you please show how it looks like in /usr? Is it like I asked above? So, how does the deploy directory (/usr in your case) look like?

sorry for annoying
i just added to a .pro file as usual :
target.path = /usr INSTALLS += target DISTFILES +=now on my beaglebone /usr/ folder looks like

@Andrey-Shmelew You should really upload a bigger picture - it is nearly impossible to see anything. I tried hard but could not find main.qml file there. So, where is it?

@Andrey-Shmelew And you should not pollute /usr with files of your app. It is better to use /opt/YOUR_APP_NAME.

@Andrey-Shmelew That's why it is not working

QDeclarativeView
It says what you should do: use QDeclarativeView instead of QQuickView

ok, i solved the problem:
put manually main.qml into /usr/ foldermain.cpp
#include <QGuiApplication> #include <QQmlApplicationEngine> int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("/usr/main.qml"))); return app.exec(); } -

And you should construct the path at runtime, as I suggested before, else if you change the installation directory later you will need to change your code and rebuild the app.
