NAME
       QWSInputMethod - International input methods for Qt/Embedded

SYNOPSIS
       #include <qwindowsystem_qws.h>

   Public Members
       QWSInputMethod ()
       virtual ~QWSInputMethod ()
       virtual bool filter ( int unicode, int keycode, int modifiers, bool isPress, bool
	   autoRepeat ) = 0
       virtual void reset ()
       virtual void setMicroFocus ( int x, int y )
       virtual void setFont ( const QFont & )

   Protected Members
       void sendIMEvent ( QWSServer::IMState state, const QString & txt, int cpos, int selLen = 0
	   )

DESCRIPTION
       The QWSInputMethod class provides international input methods for Qt/Embedded.

       Subclass this class to implement your own input method.

       An input methods consists of a keyboard filter and optionally a graphical interface. The
       keyboard filter intercepts key events from physical or virtual keyboards by implementing
       the filter() function.

       Use sendIMEvent() to send composition events. Composition starts with the input method
       sending an IMStart event, followed by a number of IMCompose events and ending with an
       IMEnd event or when the virtual reset() function is called.

       The functions setMicroFocus() and setFont() can be reimplemented to receive more
       information about the state of the focus widget.

       Use QWSServer::setCurrentInputMethod() to install an input method.

MEMBER FUNCTION DOCUMENTATION
QWSInputMethod::QWSInputMethod ()
       Constructs a new input method

QWSInputMethod::~QWSInputMethod () [virtual]
       Destructs the input method uninstalling it if it is currently installed.

bool QWSInputMethod::filter ( int unicode, int keycode, int modifiers, bool isPress, bool
       autoRepeat ) [pure virtual]
       This function must be implemented in subclasses to handle key input from physical or
       virtual keyboards. Returning TRUE will block the event from further processing.

       The Unicode value is given in unicode and the key code in keycode. Keyboard modifiers are
       OR-ed together in modifiers. If isPress is TRUE this is a key press; otherwise it is a key
       release. If autoRepeat is TRUE this is an auto-repeated key press.

       All normal key events should be blocked while in compose mode (i.e., between IMStart and
       IMEnd).

void QWSInputMethod::reset () [virtual]
       Implemented in subclasses to reset the state of the input method.

void QWSInputMethod::sendIMEvent ( QWSServer::IMState state, const QString & txt, int cpos, int
       selLen = 0 ) [protected]
       Causes a QIMEvent to be sent to the focus widget. state may be one of QWSServer::IMStart,
       QWSServer::IMCompose and QWSServer::IMEnd.

       txt is the text being composed (or the finished text if state is IMEnd). cpos is the
       current cursor position.

       If state is IMCompose, selLen is the number of characters in the composition string (
       starting at cpos ) that should be marked as selected by the input widget receiving the
       event.

void QWSInputMethod::setFont ( const QFont & ) [virtual]
       Implemented in subclasses to handle font changes in the focus widget.

       This functionality is provided for future expansion; it is not used in this version of
       Qt/Embedded.

void QWSInputMethod::setMicroFocus ( int x, int y ) [virtual]
       Implemented in subclasses to handle microFocusHint changes in the focus widget. x and y
       are the global coordinates of the
