QT获取lineEdit内容并写入文件中_qt获取lineedit的内容

在ui中创建一个lineEdit
然后
QString sss=ui->lineEdit->text();
这样就获得了lineEdit的内容，并转为了QString格式,接下来参考

这篇文章，
加一句
*outFile<<sss;
即可！

代码如下

void test::stringTest()
{
    QString sss= ui->lineEdit->text();


    system("gnome-terminal -- bash -c 'touch 1.sh'&");
    QFile *myFile;
    QTextStream *outFile;
    QString filename="./1.sh";
    myFile=new QFile(filename);
    myFile->open(QIODevice::WriteOnly | QIODevice::Text);
    outFile=new QTextStream(myFile);

    *outFile<<"#!/bin/bash\n";
    *outFile<<"ls\n";//发现当前目录是1.sh所在目录，即build目录
    *outFile<<"sleep 4\n";//等4s
    *outFile<<"exit 0\n";//关闭终端
    myFile->close();

    system("gnome-terminal -- bash -c 'chmod +x ./1.sh'&");
    system("gnome-terminal -- bash -c 'vim ./1.sh'&");
}
