使用QProcess QThread

============================================

#include

int main()

{

QProcess::execute("ls");

return 0;

}

============================================

QProcess *poc = new QProcess;

poc-> start( "ping 222.207.53.1> hh ");

打開hh文檔 讀取里面的內容給QTextEdit

============================================

QProcess *proc = new QProcess;

proc->addArgument("qmake");

proc->addArgument("-o");

proc->addArgument("/home/sjq/work/jobs/test6/test/Makefile");

proc->addArgument("/home/sjq/work/jobs/test6/test/cmd.pro");

if(proc->start())

{

cout<<"error"<<endl;

}

其中使用方法就在于對QProcess 的調用如

mkdir TEST

QProcess *proc = new QProcess;

proc->addArgument("mkdir");

proc->addArgument("TEST");

if(proc->start())

{

cout<<"error"<<endl;

}

============================================

另外的一種使用方法，一種交換

while ( proc-> isRunning())

{

stringOut = proc-> readLineStdout();

textEdit-> append( stringOut );

}

這樣能讀出來，但是不知道怎么停下來，在讀的proc執行的過程中，窗口被凍結

最后用了qApp-> processEvents()來解決的

我再去研究研究pthread.

============================================

下面是使用Qthread的一種方法

===============================================

#include

#include

class MyThread : public QThread

{

public:

void run();

};

void MyThread::run()

{

QProcess::execute("service lighttpd restart");

}

int main()

{

MyThread *thread=new MyThread;

thread->start();

}

============================================

#include

#include

#include

#include

class MyThread : public QThread

{

public:

void run();

};

void MyThread::run()

{

QProcess *testc=new QProcess;

QString program = "rm";

QStringList arguments;

arguments << "./a.txt";

testc->start(program, arguments);

}

int main()

{

MyThread *thread=new MyThread;

thread->start();

}
