| 54 |
|
|---|
| 55 | The QWSInputMethod class provides international input methods
|
|---|
| 56 | for Qt/Embedded.
|
|---|
| 57 | <p>
|
|---|
| 58 | <p> Subclass this class to implement your own input method.
|
|---|
| 59 | <p> An input methods consists of a keyboard filter and optionally a
|
|---|
| 60 | graphical interface. The keyboard filter intercepts key events
|
|---|
| 61 | from physical or virtual keyboards by implementing the <a href="#filter">filter</a>()
|
|---|
| 62 | function.
|
|---|
| 63 | <p> Use <a href="#sendIMEvent">sendIMEvent</a>() to send composition events. Composition starts
|
|---|
| 64 | with the input method sending an <tt>IMStart</tt> event, followed by a
|
|---|
| 65 | number of <tt>IMCompose</tt> events and ending with an <tt>IMEnd</tt> event or
|
|---|
| 66 | when the virtual <a href="#reset">reset</a>() function is called.
|
|---|
| 67 | <p> The functions <a href="#setMicroFocus">setMicroFocus</a>() and <a href="#setFont">setFont</a>() can be reimplemented
|
|---|
| 68 | to receive more information about the state of the focus widget.
|
|---|
| 69 | <p> Use QWSServer::setCurrentInputMethod() to install an input method.
|
|---|
| 70 | <p> <p>See also <a href="qws.html">Qt/Embedded</a>.

| 73 | <h3 class=fn><a name="QWSInputMethod"></a>QWSInputMethod::QWSInputMethod ()
|
|---|
| 74 | </h3>
|
|---|
| 75 | Constructs a new input method
|
|---|
| 76 |
|
|---|
| 77 | <h3 class=fn><a name="~QWSInputMethod"></a>QWSInputMethod::~QWSInputMethod ()<tt> [virtual]</tt>
|
|---|
| 78 | </h3>
|
|---|
| 79 | Destructs the input method uninstalling it if it is currently installed.
|
|---|
| 80 |
|
|---|
| 81 | <h3 class=fn>bool <a name="filter"></a>QWSInputMethod::filter ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat )<tt> [pure virtual]</tt>
|
|---|
| 82 | </h3>
|
|---|
| 83 |
|
|---|
| 84 | <p> This function must be implemented in subclasses to handle key
|
|---|
| 85 | input from physical or virtual keyboards. Returning TRUE will
|
|---|
| 86 | block the event from further processing.
|
|---|
| 87 | <p> The Unicode value is given in <em>unicode</em> and the key code in <em>keycode</em>. Keyboard modifiers are OR-ed together in <em>modifiers</em>.
|
|---|
| 88 | If <em>isPress</em> is TRUE this is a key press; otherwise it is a key
|
|---|
| 89 | release. If <em>autoRepeat</em> is TRUE this is an auto-repeated key
|
|---|
| 90 | press.
|
|---|
| 91 | <p> All normal key events should be blocked while in compose mode
|
|---|
| 92 | (i.e., between <tt>IMStart</tt> and <tt>IMEnd</tt>).
|
|---|
| 93 | <p>
|
|---|
| 94 | <h3 class=fn>void <a name="reset"></a>QWSInputMethod::reset ()<tt> [virtual]</tt>
|
|---|
| 95 | </h3>
|
|---|
| 96 | Implemented in subclasses to reset the state of the input method.
|
|---|
| 97 |
|
|---|
| 98 | <h3 class=fn>void <a name="sendIMEvent"></a>QWSInputMethod::sendIMEvent ( QWSServer::IMState state, const <a href="qstring.html">QString</a> & txt, int cpos, int selLen = 0 )<tt> [protected]</tt>
|
|---|
| 99 | </h3>
|
|---|
| 100 |
|
|---|
| 101 | <p> Causes a <a href="qimevent.html">QIMEvent</a> to be sent to the focus widget. <em>state</em> may be
|
|---|
| 102 | one of <a href="qwsserver.html#IMState-enum">QWSServer::IMStart</a>, <a href="qwsserver.html#IMState-enum">QWSServer::IMCompose</a> or <a href="qwsserver.html#IMState-enum">QWSServer::IMEnd</a>.
|
|---|
| 103 | <p> <em>txt</em> is the text being composed (or the finished text if state
|
|---|
| 104 | is <tt>IMEnd</tt>). <em>cpos</em> is the current cursor position.
|
|---|
| 105 | <p> If state is <tt>IMCompose</tt>, <em>selLen</em> is the number of characters in
|
|---|
| 106 | the composition string (starting at <em>cpos</em>) that should be
|
|---|
| 107 | marked as selected by the input widget receiving the event.
|
|---|
| 108 |
|
|---|
| 109 | <h3 class=fn>void <a name="setFont"></a>QWSInputMethod::setFont ( const <a href="qfont.html">QFont</a> & )<tt> [virtual]</tt>
|
|---|
| 110 | </h3>
|
|---|
| 111 | Implemented in subclasses to handle font changes in the focus
|
|---|
| 112 | widget.
|
|---|
| 113 | <p> This functionality is provided for future expansion; it is not
|
|---|
| 114 | used in this version of Qt/Embedded.
|
|---|
| 115 |
|
|---|
| 116 | <h3 class=fn>void <a name="setMicroFocus"></a>QWSInputMethod::setMicroFocus ( int x, int y )<tt> [virtual]</tt>
|
|---|
| 117 | </h3>
|
|---|
| 118 |
|
|---|
| 119 | <p> Implemented in subclasses to handle microFocusHint changes in the
|
|---|
| 120 | focus widget. <em>x</em> and <em>y</em> are the global coordinates of the
|
|---|
| 121 | text cursor.
