The use of processes in QT

The process used in QT needs to use the header file:include<qprocess>

First, let's look at the main functions that need to be used.

(1) Definition of the process:

  // define a process parameter

(2) Initialization of the process:

// Initializing Process Objects New Qprocess ();

(3) Start process

// Start Calculator  Mprocess->start ("calc"

(4) using process to read data

 while // read all the data in the process

(5) How to use the character stitching Qstringlist

    qstringlist list;     // stitching strings, similar    to Appen list<<"ech0";    List<<ui->comboBoxArg->currenttext ();    Mprocess->start (Ui->comboboxcmd->currenttext (), list); // start the process, followed by the parameter

Head function: Process.h
