<h2 id="details">Detailed Description</h2>
<p>实质性的功能皆在dxcb插件中实现，此插件目前只 支持X11平台，在其它平台上使用这个类不会有任何效果。关于dxcb：它介于Qt应用和Qt xcb平台 插件之间，通过覆写xcb插件中某些对象的虚函数来改变它的一些行为，本质上来讲是Qt xcb插件的 扩展，在X11平台上为DTK应用提供了一些改变窗口效果的功能（比如自定义窗口的边框）、其它和平 台密切相关的实现（比如修复Qt应用在X11平台的一些bug），不能脱离Qt xcb插件独立运行。dxcb 通过重载 QPlatformNativeInterface 提供接口，DPlatformHandle 中使用 <a href="http://doc.qt.io/qt-5/qguiapplication.html#platformFunction">QGuiApplication::platformFunction</a> 调用这些接口。Application、dxcb、qt xcb 之间 的关系：</p>

<p><b>Warning:</b> 使用此工具前要确保应用加载了dxcb插件</p>
<p><b>Warning:</b> 因为 <a href="http://doc.qt.io/qt-5/qguiapplication.html#platformFunction">QGuiApplication::platformFunction</a> 是在 Qt 5.4.0 版本引入的新接口， 所以 DPlatformHandle 不支持 Qt 5.4.0 以下版本。</p>
