How to move and resize a Application with no title bar and border?

[smaranil]

i used

w.setWindowFlags(Qt::Window | Qt::FramelessWindowHint);

w.setWindowFlags(Qt::Window | Qt::FramelessWindowHint);

To copy to clipboard, switch view to plain text mode

main.cpp

#include "mainwindow.h"
#include <QApplication>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
 
    w.setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
    w.show();
 
 
 
    return a.exec();
}

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])

    QApplication a(argc, argv);
    MainWindow w;

    w.setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
