的.pro

# Add more folders to ship with the application, here
folder_01.source = qml/qmlDeploy
folder_01.target = qml
DEPLOYMENTFOLDERS = folder_01

TEMPLATE += app
QT += qml

# The .cpp file which was generated for your project. Feel free to hack it.
SOURCES += main.cpp

# Please do not modify the following two lines. Required for deployment.
include(qtquick2applicationviewer/qtquick2applicationviewer.pri)
qtcAddDeployment()

RESOURCES += \
    resource.qrc

的main.cpp

#include <QGuiApplication>
#include <QQuickView>

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QQuickView view;
    //view.setSource(QUrl::fromLocalFile("qml/qmlDeploy/main.qml"));
    view.setSource (QUrl::fromLocalFile("qrc:/main.qml"));
    view.show();

    return app.exec();
}

resource.qrc

<!DOCTYPE RCC>
<RCC version="1.0">

<qresource prefix="/">
    <file>qml/qmlDeploy/main.qml</file>
</qresource>

</RCC>

main.qml

import QtQuick 2.0

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

问题陈述:

当我使用QtCreator编译上述程序时,会显示以下错误:
错误:

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

答案 0 :(得分:6)

QUrl::fromLocalFile ()根本不适合与Qt资源一起使用,因为显然资源包是 NOT 本地文件,而且,QML文件不在Qt资源文件的根目录所以你必须在它之前添加路径:所以只需使用QUrl ("qrc:/qml/qmlDeploy/main.qml")

PS:如果你想避免像这样的长路径,只需将.qrc文件移动到与QML文件相同的目录中,你就会有更短的URL。

答案 1 :(得分:2)

我认为问题出在这一行:

view.setSource (QUrl::fromLocalFile("qrc:/main.qml"));

您的URL语法错误。您正在尝试在qrc:目录中打开文件。

应该是这样的:

view.setSource (QUrl("qrc:///qml/qmlDeploy/main.qml"));

由于qrc://是网址前缀,/是根前缀,main.qml是其中的文件。
