QT 5.4，无法从代码访问资源 [英] QT 5.4, Unable to access Resource from code

问题描述

我尝试将我的应用程序的样式图像包含到q资源文件中.当我将文件直接包含在代码中时，它可以工作，但是当我尝试使用QResource时，它会失败(请不要加载文件).

I try to include style images of my app into a q-resource file. When I include the file directly in the code, it work, but when i try to use QResource, it fail (do not load the file).

我在主目录中有资源文件:

I have the resource file in the main directory:

AppFolder
  |- main.cpp
  |- darkstyle.qrc
  |- darkstyle
       |- WindowTitleBar.png

以下示例打印:失败1失败2

The following example print: failed1 failed2

#include <QApplication>
#include <QResource>
#include <Qfile>
#include <QDebug>


int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    bool ok= QResource::registerResource("darkstyle.qrc");
    if (!ok) qDebug()<<"failed1";

    QFile file(":/darkstyle/WindowTitleBar.png");
    //QFile file("../AppFolder/darkstyle/WindowTitleBar.png"); //that work

    if(!file.open(QFile::ReadOnly | QFile::Text)) qDebug()<<"failed2";
    else file.close();

    //return a.exec();
    return 0;
}

注意:默认情况下，Qt创建器在顶部文件夹中创建二进制文件(.exe):../build-AppFolder_Qt_5_4_1_MSVC2013_64bit-Debug/debug/AppFolder.exe执行根路径似乎是:../build-AppFolder_Qt_5_4_1_MSVC2013_64bit-Debug

Note: Qt creator by default create binaries (.exe) in a top folder: ../build-AppFolder_Qt_5_4_1_MSVC2013_64bit-Debug/debug/AppFolder.exe The execution root path seem to be: ../build-AppFolder_Qt_5_4_1_MSVC2013_64bit-Debug

我尝试了执行路径的大多数可能组合.

I tried most of possible combinations with execution paths.

注2:有些示例使用.rcc文件格式，我没有这些格式，但这可能是一个线索.

Note2: Some examples use a .rcc file format, I have none of these, but that could be a clue.
