The QWSInputMethod class provides international input methods for Qt/Embedded. More...
#include <qwindowsystem_qws.h>
Inherits QObject.
Subclass this 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 the first IMCompose
event. This can be
followed by a number of IMCompose
events and ending with an IMEnd
event.
The function setMicroFocus() is called when the focus widget changes its cursor position.
The functions font() and inputRect() provide more information about the state of the focus widget.
Use QWSServer::setCurrentInputMethod() to install an input method.
Constructs a new input method.
[virtual]
Destructs the input method uninstalling it if it is currently installed.
[virtual]
Must be implemented in subclasses to handle key input from physical or virtual keyboards. Returning TRUE will block the event from further processing.
All normal key events should be blocked while in compose mode
(between IMCompose
and IMEnd).
Returns the font of the current input widget.
Returns the input rectangle of the current input widget. The input rectangle covers the width of the input widget, and may extend below it. This can be used to determine the geometry of an input widget for over-the-spot input methods.
[virtual]
Implemented in subclasses to handle mouse presses/releases within
the on-the-spot text. The parameter x is the offset within
the string that was sent with the IMCompose event.
state is either QWSServer::MousePress
or QWSServer::MouseRelease
[virtual]
Implemented in subclasses to reset the state of the input method.
[protected]
Causes a QIMEvent to be sent to the focus widget. state may be either
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.
[virtual]
Implemented in subclasses to handle microFocusHint changes in the focus widget. x and y are the global coordinates of the cursor position.
