25 The QWSInputMethod class provides international input methods for
26 Qt/Embedded.
27 Subclass this class to implement your own input method.
29 An input methods consists of a keyboard filter and optionally a
31 graphical interface. The keyboard filter intercepts key events from
32 physical or virtual keyboards by implementing the filter() function.
33 Use sendIMEvent() to send composition events. Composition starts with
35 the input method sending an IMStart event, followed by a number of
36 IMCompose events and ending with an IMEnd event or when the virtual
37 reset() function is called.
38 The functions setMicroFocus() and setFont() can be reimplemented to
40 receive more information about the state of the focus widget.
41 Use QWSServer::setCurrentInputMethod() to install an input method.
43 See also Qt/Embedded.
45
48 Constructs a new input method
49
51 Destructs the input method uninstalling it if it is currently
52 installed.
53
55 isPress, bool autoRepeat ) [pure virtual]
56 This function must be implemented in subclasses to handle key input
57 from physical or virtual keyboards. Returning TRUE will block the event
58 from further processing.
59 The Unicode value is given in unicode and the key code in keycode.
61 Keyboard modifiers are OR-ed together in modifiers. If isPress is TRUE
62 this is a key press; otherwise it is a key release. If autoRepeat is
63 TRUE this is an auto-repeated key press.
64 All normal key events should be blocked while in compose mode (i.e.,
66 between IMStart and IMEnd).
67
69 Implemented in subclasses to reset the state of the input method.
70
72 txt, int cpos, int selLen = 0 ) [protected]
73 Causes a QIMEvent to be sent to the focus widget. state may be one of
74 QWSServer::IMStart, QWSServer::IMCompose or QWSServer::IMEnd.
75 txt is the text being composed (or the finished text if state is
77 IMEnd). cpos is the current cursor position.
78 If state is IMCompose, selLen is the number of characters in the
80 composition string (starting at cpos) that should be marked as selected
81 by the input widget receiving the event.
82
84 Implemented in subclasses to handle font changes in the focus widget.
85 This functionality is provided for future expansion; it is not used in
87 this version of Qt/Embedded.
88
90 Implemented in subclasses to handle microFocusHint changes in the focus
91 widget. x and y are the global coordinates of the text cursor.
