详细描述

The QDecorationPlugin class is an abstract base class for window decoration plugins in Qt for Embedded Linux.

注意，此类只可用于 Qt for Embedded Linux .

Qt for Embedded Linux provides three ready-made decoration styles: 默认 , Styled and Windows . Custom decorations can be implemented by subclassing the QDecoration class and creating a decoration plugin.

A decoration plugin can be created by subclassing QDecorationPlugin and implementing the pure virtual keys () 和 create () functions. By exporting the derived class using the Q_EXPORT_PLUGIN2 () macro, the default implementation of the QDecorationFactory class will automatically detect the plugin and load the driver into the application at run-time. See 如何创建 Qt 插件了解细节。

To actually apply a decoration, use the QApplication::qwsSetDecoration () 函数。

另请参阅 QDecoration and QDecorationFactory .

成员函数文档编制

QDecorationPlugin:: QDecorationPlugin ( QObject * parent = 0)

Constructs a decoration plugin with the given parent .

Note that this constructor is invoked automatically by the Q_EXPORT_PLUGIN2 () macro, so there is no need for calling it explicitly.

QDecorationPlugin:: ~QDecorationPlugin ()

Destroys the decoration plugin.

Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.

`[pure virtual]` QDecoration * QDecorationPlugin:: create (const QString & key )

Creates a decoration matching the given key . Note that keys are case-insensitive.

另请参阅 keys ().

`[pure virtual]` QStringList QDecorationPlugin:: keys () const

Returns the list of valid keys, i.e., the decorations supported by this plugin.

另请参阅 create ().
