Detailed 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 or 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 +text cursor. +
