Borderless Window on Mac OS X

[shailesh83]

Hello,
As i am new to Qt 5.4 on Mac OS X.I have wondering how to achieve Borderless Window and customising Mac OS X Window with my Window.
Code i used:
setWindowFlags( Qt::FramelessWindowHint | Qt::CustomizeWindowHint);
yeah it make my window customizable and hides "minimise","maximise","close" window.
And i add my own customized "minimise","maximise","close" button.
Also i used following code to achieve Mac functionality using following code:
Minimise Window :

window()->showMinimized();
or
window()->setWindowState(Qt::WindowMinimized);

Maximize window:

if(window()->windowState() == Qt::WindowMaximized)
{
window()->showNormal();
}
else
{
window()->showMaximized();
}
Quit Window:

qApp->quit();

Please can some one help me how to add minimise,maximise and close functionality in Mac OS X using Qt.As i think i need to write some code in objective C++.i tried that but its not compiling as well giving error for HIViewGetWindow undefined:

ChangeWindowAttributes(HIViewGetWindow(HIViewRef(window()->winId())), kWindowSideTitlebarAttribute, 0);
