Customize Application Window

[yxmaomao]

In Qt 4.3 you can get title bar's height :
qApp->style()->pixelMetric(QStyle::PM_TitleBarHeight,NULL,NULL )

How about trying setWindowFlags ??
You can use "Qt::Window| Qt::WindowMinimizeButtonHint" to disable the maximize button

You can play more with the flags I guess
