The QWSInputMethod class provides international input methods for Qt/Embedded. More...
List of all member functions.
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.
See also Qt/Embedded.
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).
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.
This functionality is provided for future expansion; it is not used in this version of Qt/Embedded.
Implemented in subclasses to handle microFocusHint changes in the focus widget. x and y are the global coordinates of the text cursor.
