Prevent Taskbar from displaying in QWidget Fullscreen application.

[mbatra]

Hi,

I have created a QWidget application.
In main.cpp:

#include "mainwindow.h"

#include <QApplication>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.showFullScreen();
return a.exec();
}

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

this->setWindowFlags( Qt::WindowStaysOnTopHint );

}

I have created a button. When I click the button, a batch file starts running. When I click the button, taskbar displays on top of the window. covers the bottom part.
How to prevent taskbar from displaying.

Any help would be appreciated.

Thanks.
