如何在c ++和QML应用程序中使用qrc？ [英] How to use qrc in c++ and QML application?

问题描述

我在Windows7上用c ++ qnd Qt Creator（QML）编写了一个Qt Quick Desktop应用程序。现在
我必须部署它，我需要隐藏qml文件和图像（意味着：把它们放在资源等）。

我'读了，有一个伟大的方法来做这个.qrc文件。我读了关于这些文件的文档，并为我的应用程序创建了一个，它看起来像这样：

 < RCC& 
< qresource prefix =/> 
< file> qml / GenericHostApplicationQML / myMain.qml< / file> 
< file> qml / GenericHostApplicationQML / content / PressAndHoldButton.qml< / file> 
< file> qml / GenericHostApplicationQML / content / TextButton.qml< / file> 
< file> qml / GenericHostApplicationQML / content / pics / advancedsettings.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / cnruninstall.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / dialog_cancel.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / folder_explore.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / gnome_session_switch.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / mail2_send.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / Picture1.png< / file> 
< file> qml / GenericHostApplicationQML / content / pics / Picture2.png< / file> 
< / qresource> 
  
 
 
 
 
 
 
 
我加载Main.qml文件像：
  int main（int argc，char * argv []）
 {
 QApplication app（argc，argv）; 
 QDeclarativeView view; 
 view.setSource（QUrl :: fromLocalFile（qml / GenericHostApplicationQML / myMain.qml））; 
 view.show（）; 
 return app.exec（）; 
} 
  
我试图从Resources.qrc中读取myMain.qml文件： 
  view.setSource（QUrl（：/ qml / GenericHostApplicationQML / myMain.qml））; //我添加了 ：/
  
但我遇到此错误：
  file：///qml/GenericHostApplicationQML/myMain.qml：找不到文件
  
，当我尝试这个时：
  view.setSource（QUrl :: fromLocalFile /qml/GenericHostApplicationQML/myMain.qml））; 
  
我得到这个：
  file：/// C：/ Users / ayalafre / Desktop / ghaQML / GenericHostApplicationQML-build-desktop-Qt_4_7_4_for_Desktop _-_ MinGW_4_4__Qt_SDK__Release /：/qml/GenericHostApplicationQML/myMain.qml：找不到文件
  
似乎我的Qt不知道该怎么办：：/。
 
 
 
我必须使用.qrc文件：
 
 
 
 
 
加载myMain.qml文件
 
 
在myMain.qml中使用导入qml文件
 
 
在我的qml文件中使用图片
 
 
 
 
 
你能向我解释什么是错误吗？ 
和为了在c ++和qml中使用.qrc，我必须做什么？
 
 
 
非常感谢。）
解决方案
您尝试过：
  view.setSource （QUrl（qrc：/qml/GenericHostApplicationQML/myMain.qml））; 
  
执行此操作时：
  QUrl（：/ qml / GenericHostApplicationQML / myMain.qml）; 
  
路径是file：///qml/GenericHostApplicationQML/myMain.qml
 
I have written a Qt Quick Desktop application in c++ qnd Qt Creator(QML) on Windows7. Now
I have to deploy it, and I need to hide the qml files and the images(means: to put them in resources and etc.)

I've read that there is a great way to do that with .qrc files. I read the documentation about those files, and created one for my application, which looks like this:
<RCC>
<qresource prefix="/">
    <file>qml/GenericHostApplicationQML/myMain.qml</file>
    <file>qml/GenericHostApplicationQML/content/PressAndHoldButton.qml</file>
    <file>qml/GenericHostApplicationQML/content/TextButton.qml</file>
    <file>qml/GenericHostApplicationQML/content/pics/advancedsettings.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/cnruninstall.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/dialog_cancel.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/folder_explore.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/gnome_session_switch.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/mail2_send.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/Picture1.png</file>
    <file>qml/GenericHostApplicationQML/content/pics/Picture2.png</file>
</qresource>


In the main.cpp, I'm loading the Main.qml file like:
int main(int argc, char *argv[])
{
   QApplication app(argc, argv);
   QDeclarativeView view;
   view.setSource(QUrl::fromLocalFile("qml/GenericHostApplicationQML/myMain.qml"));
   view.show();
   return app.exec();
}
I tried to read the myMain.qml file from the Resources.qrc like:
view.setSource(QUrl(":/qml/GenericHostApplicationQML/myMain.qml"));//I added the ":/"
but I've got this error:
file:///qml/GenericHostApplicationQML/myMain.qml: File not found 
and when I tried this:
view.setSource(QUrl::fromLocalFile(":/qml/GenericHostApplicationQML/myMain.qml"));
I'm getting this:
file:///C:/Users/ayalafre/Desktop/ghaQML/GenericHostApplicationQML-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Release/:/qml/GenericHostApplicationQML/myMain.qml: File not found
It seems like my Qt doesn't know what to do with:":/".

I have to use the .qrc file in:


Loading the myMain.qml file
Using import to qml files in myMain.qml
Using images in my qml files


Could you explain to me what's wrong??
and what I have to do in order to use the .qrc in both c++ and qml?

Thanks a lot:)
解决方案
Have you try this:
view.setSource(QUrl("qrc:/qml/GenericHostApplicationQML/myMain.qml"));
When you do this:
QUrl(":/qml/GenericHostApplicationQML/myMain.qml");
the path is "file:///qml/GenericHostApplicationQML/myMain.qml"
