深圳有哪些网站建设wordpress 插件设置

一.所需运行的脚本

        本篇采用上一篇文章的脚本为运行对象，实现按钮运行脚本

        上一篇文章：从0到1：QT项目在Linux下生成可以双击运用的程序（采用脚本）-CSDN博客

二.调用脚本的代码

widget.cpp中添加以下代码

#include "widget.h"
#include "./ui_widget.h"
#include <QMessageBox>
#include <QProcess>Widget::Widget(QWidget *parent): QWidget(parent), ui(new Ui::Widget)
{ui->setupUi(this);connect(ui->pushButton_test, &QPushButton::clicked, this, &Widget::on_pushButton_test_clicked);
}void Widget::on_pushButton_test_clicked()
{QString strCmd = "/home/popo/double_click_test/jiao";QProcess process;process.start("bash", QStringList() << "-c" << strCmd);if (process.waitForStarted()){qDebug() << "Process started successfully.";if (process.waitForFinished()){QByteArray result = process.readAllStandardOutput(); // 读取脚本的输出QByteArray error = process.readAllStandardError(); // 读取错误输出qDebug() << "Script output:" << result;qDebug() << "Script error output:" << error;}else{qWarning() << "Failed to execute script";}}else{qWarning() << "Failed to start script execution";}process.close();
}

三.代码解析

启动进程

process.start("bash", QStringList() << "-c" << strCmd);

检查进程是否成功启动

if (process.waitForStarted())

等待进程执行完成 

再次使用 waitForFinished，等待进程执行完成。如果成功，返回 true。

进程提示信息

    if (process.waitForStarted()){qDebug() << "Process started successfully.";if (process.waitForFinished()){QByteArray result = process.readAllStandardOutput(); // 读取脚本的输出QByteArray error = process.readAllStandardError(); // 读取错误输出qDebug() << "Script output:" << result;qDebug() << "Script error output:" << error;}else{qWarning() << "Failed to execute script";}}else{qWarning() << "Failed to start script execution";}

关闭进程 

process.close();
