main.qml

import QtQuick 2.0

Rectangle { width: 100; height: 100; color: "red" }

Problem statement:

When I compile the above programs using QtCreator the following error is shown:
Error:

file:///home/ppp/documents/test/build-qmlDeploy-Desktop_Qt_5_1_0_GCC_64bit-Debug/qrc:/main.qml: File not found

Answer 1

QUrl::fromLocalFile () is simply not meant to be used with Qt Resource, as obviously resource bundle is NOT local file, and also, QML file is not at the root of Qt resource file so you have to add the path before it : so just use QUrl ("qrc:/qml/qmlDeploy/main.qml") !

PS: If you want to avoid long paths, like this, just move the .qrc file in the same dir as QML files, and you will have shorter URL.
