.SH DESCRIPTION
|
|
The QWSInputMethod class provides international input methods for Qt/Embedded.
|
|
.PP
|
|
Subclass this class to implement your own input method.
|
|
.PP
|
|
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.
|
|
.PP
|
|
Use sendIMEvent() to send composition events. Composition starts with the input method sending an \fCIMStart\fR event, followed by a number of \fCIMCompose\fR events and ending with an \fCIMEnd\fR event or when the virtual reset() function is called.
|
|
.PP
|
|
The functions setMicroFocus() and setFont() can be reimplemented to receive more information about the state of the focus widget.
|
|
.PP
|
|
Use QWSServer::setCurrentInputMethod() to install an input method.
|
|
.PP
|
|
See also Qt/Embedded.
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QWSInputMethod::QWSInputMethod ()"
|
|
Constructs a new input method
|
|
.SH "QWSInputMethod::~QWSInputMethod ()\fC [virtual]\fR"
|
|
Destructs the input method uninstalling it if it is currently installed.
|
|
.SH "bool QWSInputMethod::filter ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat )\fC [pure virtual]\fR"
|
|
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.
|
|
.PP
|
|
The Unicode value is given in \fIunicode\fR and the key code in \fIkeycode\fR. Keyboard modifiers are OR-ed together in \fImodifiers\fR. If \fIisPress\fR is TRUE this is a key press; otherwise it is a key release. If \fIautoRepeat\fR is TRUE this is an auto-repeated key press.
|
|
.PP
|
|
All normal key events should be blocked while in compose mode (i.e., between \fCIMStart\fR and \fCIMEnd\fR).
|
|
.SH "void QWSInputMethod::reset ()\fC [virtual]\fR"
|
|
Implemented in subclasses to reset the state of the input method.
|
|
.SH "void QWSInputMethod::sendIMEvent ( QWSServer::IMState state, const QString & txt, int cpos, int selLen = 0 )\fC [protected]\fR"
|
|
Causes a QIMEvent to be sent to the focus widget. \fIstate\fR may be one of QWSServer::IMStart, QWSServer::IMCompose or QWSServer::IMEnd.
|
|
.PP
|
|
\fItxt\fR is the text being composed (or the finished text if state is \fCIMEnd\fR). \fIcpos\fR is the current cursor position.
|
|
.PP
|
|
If state is \fCIMCompose\fR, \fIselLen\fR is the number of characters in the composition string (starting at \fIcpos\fR) that should be marked as selected by the input widget receiving the event.
|
|
.SH "void QWSInputMethod::setFont ( const QFont & )\fC [virtual]\fR"
|
|
Implemented in subclasses to handle font changes in the focus widget.
|
|
.PP
|
|
This functionality is provided for future expansion; it is not used in this version of Qt/Embedded.
|
|
.SH "void QWSInputMethod::setMicroFocus ( int x, int y )\fC [virtual]\fR"
|
|
Implemented in subclasses to handle microFocusHint changes in the focus widget. \fIx\fR and \fIy\fR are the global coordinates of the text cursor.
