讓Qt支持Win7的Aero和毛玻璃效果

Qt5增加了許多特性，其中 Qt Windows Extras 模塊就增加了對Win7 Aero 效果的支持。

官網的介紹如下：

Qt Windows Extras provide classes and functions that enable you to use miscellaneous Windows-specific functions. For example, you can convert Qt objects to Windows object handles and manipulate DWM glass frames.

 

In addition, you can use features introduced with Windows 7, such as Aero Peek, Jump Lists, a progress indicator on a taskbar button, or a thumbnail toolbar.

    現在我們將該模塊來實現Win7的Aero窗口。

步驟（1）：在Qt工程中添加模塊：winextras
步驟（2）：包含頭文件：<QtWin>

源代碼（從Qt5示例中截取來的）：

if (QtWin::isCompositionEnabled())                           //返回DWM組合狀態
{
   QtWin::extendFrameIntoClientArea(this, -1, -1, -1, -1);    //玻璃效果
   setAttribute(Qt::WA_TranslucentBackground, true);         //半透明背景
   setAttribute(Qt::WA_NoSystemBackground, false);           //禁用無背景
   setStyleSheet("MusicPlayer { background: transparent; }");
}
else
{
   QtWin::resetExtendedFrame(this);
   setAttribute(Qt::WA_TranslucentBackground, false);
   setStyleSheet(QString("MusicPlayer { background: %1; }").arg(QtWin::realColorizationColor().name()));
}
