详细描述

The QMouseDriverPlugin class is an abstract base class for mouse driver plugins in Qt for Embedded Linux.

注意,此类只可用于 Qt for Embedded Linux .

Qt for Embedded Linux provides ready-made drivers for several mouse protocols, see the pointer handling documentation for details. Custom mouse drivers can be implemented by subclassing the QWSMouseHandler class and creating a mouse driver plugin.

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

成员函数文档编制

QMouseDriverPlugin:: QMouseDriverPlugin ( QObject * parent = 0)

Constructs a mouse driver 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.

QMouseDriverPlugin:: ~QMouseDriverPlugin ()

Destroys the mouse driver 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] QWSMouseHandler * QMouseDriverPlugin:: create (const QString & key , const QString & device )

Implement this function to create a driver matching the type specified by the given key and device parameters. Note that keys are case-insensitive.

另请参阅 keys ().

[pure virtual] QStringList QMouseDriverPlugin:: keys () const

Implement this function to return the list of valid keys, i.e. the mouse drivers supported by this plugin.

Qt for Embedded Linux provides ready-made drivers for several mouse protocols, see the pointer handling 文档编制了解细节。
