Customize the window in windows ?

[iNewLegend]

Hello im good C++ developer , but i never used qt im total new in it, i wonder how to make the next setps by using codes not UI , in my image i selected the things i want done in red color , i used

w.setWindowFlags(Qt::FramelessWindowHint);

w.setWindowFlags(Qt::FramelessWindowHint);

To copy to clipboard, switch view to plain text mode 

to hide windows one

    // ----
    MimimizeBt.setText("_");
    // ----
    Layout.addWidget(& CloseBt, 0, Qt::AlignRight | Qt::AlignTop);
    Layout.addWidget(& MimimizeBt, 2, Qt::AlignRight | Qt::AlignTop);
    // ----
    MainWnd.setLayout(& Layout);
    MainWnd.setWindowFlags(Qt::FramelessWindowHint);
    MainWnd.resize(800, 600);

    MainWnd.setWindowFlags(Qt::FramelessWindowHint);
    MainWnd.resize(800, 600);
