Qt界面嵌入powershell 代码-QT开发中文网

以下是Qt界面嵌入PowerShell的代码示例：

首先，在Qt项目中添加一个QPlainTextEdit控件，用于显示PowerShell的输出结果。

在头文件中添加以下代码：

#include #include

class PowerShellProcess : public QObject {

Q_OBJECT

public:

explicit PowerShellProcess(QObject *parent = nullptr);

public slots:

void startProcess();
void readOutput();
void processFinished(int exitCode, QProcess::ExitStatus exitStatus);

private:

QProcess *m_process;

};

然后，在源文件中实现PowerShellProcess类：

#include “powershellprocess.h”

PowerShellProcess::PowerShellProcess(QObject *parent)

: QObject(parent), m_process(new QProcess(this))

{ }

void PowerShellProcess::startProcess() {

connect(m_process, &QProcess::readyReadStandardOutput, this, &PowerShellProcess::readOutput);
connect(m_process, SIGNAL(finished(int, QProcess::ExitStatus)), this, SLOT(processFinished(int, QProcess::ExitStatus)));

QStringList arguments;
arguments << "-Command" << "Get-Process";

m_process->start("powershell.exe", arguments);

}

void PowerShellProcess::readOutput() {

QString output = m_process->readAllStandardOutput();
QPlainTextEdit *textEdit = qobject_cast<QPlainTextEdit*>(parent());
textEdit->appendPlainText(output.trimmed());

}

void PowerShellProcess::processFinished(int exitCode, QProcess::ExitStatus exitStatus) {

Q_UNUSED(exitCode);
Q_UNUSED(exitStatus);

QPlainTextEdit *textEdit = qobject_cast<QPlainTextEdit*>(parent());
textEdit->appendPlainText("Process finished.");

}

最后，在主窗口中创建PowerShellProcess对象并启动进程：

#include #include “mainwindow.h” #include “powershellprocess.h”

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

QApplication a(argc, argv);

MainWindow w;
w.show();

PowerShellProcess *process = new PowerShellProcess(&w);
process->startProcess();

return a.exec();

}

现在，启动程序后，您应该可以看到QPlainTextEdit控件中显示了PowerShell进程的输出结果。
