QProcess, how to correctly declare the variable, multiple event handlers.

[TeODH4]

Hey guys I know I'm doing something wrong here, any help would be much appreciated. I am trying to run mplayer in slave mode and control it. However I am having issues even controlling my QProcess! LOL I know I probably have to declare this process somewhere else before i start it, but I'm at a bit of a loss. It has been a long time since I have played around with QT. What do I need to be able to launch mplayer with a button, and close with another? Thanks.

mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QProcess>
 
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
 
}
 
MainWindow::~MainWindow()
{
    delete ui;
 
 
}
 
void MainWindow::on_pushButton_clicked()
{
    QProcess* proc = new QProcess(this);
    proc->setReadChannel(QProcess::StandardOutput);
    proc->start("mplayer/mplayer.exe -vo direct3d -noborder -x 800 -y 600 -geometry 1025:0 -udp-master -udp-ip 192.168.2.255 -osdlevel 0 center.mp4");
}
 
void MainWindow::on_pushButton_2_clicked()
{
    proc->terminate();
}

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QProcess>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);


}

MainWindow::~MainWindow()
{
    delete ui;


}

void MainWindow::on_pushButton_clicked()
{
    QProcess* proc = new QProcess(this);
    proc->setReadChannel(QProcess::StandardOutput);
    proc->start("mplayer/mplayer.exe -vo direct3d -noborder -x 800 -y 600 -geometry 1025:0 -udp-master -udp-ip 192.168.2.255 -osdlevel 0 center.mp4");
}

void MainWindow::on_pushButton_2_clicked()
{
    proc->terminate();
}
