Qt 遍历目录下所有图片

 

 

#include <QDirIterator>
#include <QDir>
#include <QFileInfo>

具体函数为：
void ModifyAngle::GetImgs(QString _dir)
{
    QDirIterator it(_dir,QDir::Files|QDir::Dirs|QDir::NoDotAndDotDot); //遍历所有目录和文件
    while (it.hasNext())//存在
    {
        QString name = it.next();//读取
        QFileInfo info(name);
        if (info.isDir())//判断是目录
        {
            this->GetImgs(name);//递归
        }
    }
}
else
{
    if (info.suffix() == "jpg" || info.suffix() == "bmp" || info.suffix() == "png")
    {
        this->plistname_.push_back(name);//符合添加
    }
}
