当我使用QtCreator编译上述程序时,会显示以下错误:
的错误:

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。

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。
