QQuickWidget no such file issue

RCtaf

Hi,

i'm having some problems displaying a qml code into a QWidget.
i'm using in this case QQuickwidget. But every time i use setLocationfrom, its telling me no such file or directory. see the code below !
i have change the location of the qml file and changed the syntax but still nothing.
my goal is to display a map in a QWidget
thanks for your help

    w = new QQuickWidget;
    w->setSource(QUrl::fromLocalFile("file:///D:/ProjetRC/mainie.qml"));

and 

file:///D:/build-ProjetRC-Desktop_Qt_5_10_1_MinGW_32bit-Debug/file:///D:/ProjetRC/mainie.qml: No such file or directory

Hi and welcome to devnet,

Did you add

QT += quickwidgets

to your pro file ?

RCtaf

Yes i did add it.
and thank you for the welcome.

SGaist

Did you de-run qmake after doing that ?

RCtaf

Yes , i did ! i cleaned and rebuilded and even close and reopened the project just to be sure but still.

SGaist

Sorry, I just realized that I missed the real missing file issue.

Remove the file:/// from your path. Since you are using QUrl to build it, just pass it the path to your file.

Thank you, its worked ! the error has gone but this appeared instead although the program is running :

QQuickWidget does not support using windows as a root item. 
If you wish to create your root window from QML, consider using QQmlApplicationEngine instead.

You have to change the main element of your QML file.

Can you share it ?
