Execute shell command in QT under Linux

You can take advantage of the following methods when you need to execute shell commands in QT:

(1) First include the header file:

#include <QProcess>

(2) Execute shell command:

Qprocess::execute ("LS");

/////////////////////

#include <QProcess>

void Widget:on_pushbutton_clicked ()

{

//*

System ("LS");//Call System (const char *string) in the Linux C function library;

*//

#######@@@@@

Qprocess:: Execute ("ls");//Call QT function

@@@@@############

----------------------

Qprocess *proc = new Qprocess;

Proc->start ("LS");

---------------------------

Tip: The above three methods are all possible, but the first two methods will block the process, knowing that the LS program ends,

The third does not block the process and can be run on multiple tasks.
