Detailed Description

The QKbdDriverPlugin class is an abstract base class for keyboard driver plugins.

Note that this class is only available in Qtopia Core.

QKbdDriverPlugin is a simple plugin interface that makes it easy to create custom keyboard drivers that can be loaded dynamically into applications using the QKbdDriverFactory class.

Writing a custom keyboard driver plugin is achieved by subclassing QKbdDriverPlugin, reimplementing the pure virtual keys() and create() functions, and exporting the class using the Q_EXPORT_PLUGIN2() macro (See How to Create Qt Plugins for details).

See also QKbdDriverFactory, QWSKeyboardHandler, and Character Input.

Member Function Documentation

QKbdDriverPlugin::QKbdDriverPlugin ( QObject * parent = 0 )

Constructs a keyboard 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.

QKbdDriverPlugin::~QKbdDriverPlugin ()

Destroys the keyboard 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.

QWSKeyboardHandler * QKbdDriverPlugin::create ( const QString & key, const QString & device )   [pure virtual]

Creates a driver matching the type specified by the given key and device parameters. Keys are case-insensitive.

See also keys().

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

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

Qtopia Core currently supports the following drivers by default: SL5000, Yopy, VR41xx, TTY and USB.

See also create().
