c – 在Qt中获取qrc文件的路径

如果在当前工作目录中有一个名为“：”的目录,它可能会中断,并且您希望将来可以对其进行解析.无论如何,这不应该是现在关注的问题.

QStringList imageFileList;
QDirIterator dirIterator(":",QDirIterator::Subdirectories);
while (dirIterator.hasNext()) {
    QFileInfo fileInfo = it.fileInfo();
    if (fileInfo.isFile()) // Do not add directories to the list
        imageFileList.append(it.next());
}

或者,这需要相当多的参与,但我认为它有效.我担心写这个没有更方便的方法.

main.qrc

<!DOCTYPE RCC><RCC version="1.0">
 <qresource prefix="">
  <file>images/1.jpg</file>
  <file>images/2.jpg</file>
  <file>images/3.jpg</file>
  <file>images/4.jpg</file>
 </qresource>
</RCC>

main.cpp中

#include <QXmlStreamReader>
#include <QString>
#include <QFile>
#include <QTextStream>

int main()
{
    QTextStream standardOutput(stdout);
    QFile file("main.qrc");
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) {
        standardOutput << "File open error:" << file.errorString() << "n";
        return 1;
    }
    QXmlStreamReader inputStream(&file);
    while (!inputStream.atEnd() && !inputStream.hasError()) {
        inputStream.readNext();
        if (inputStream.isStartElement()) {
            QString name = inputStream.name().toString();
            if (name == "file")
                standardOutput << "file: :/" << inputStream.readElementText() << "n";
        }
    }
    return 0;
}

main.pro

TEMPLATE = app
TARGET = main
QT = core
SOURCES += main.cpp

构建并运行

qmake && make && ./main
