It converts a sequence of input + events (typically key events) into a text string through the input + method specific converting process. The class of the processes are + widely ranging from simple finite state machine to complex text + translator that pools a whole paragraph of a text with text + editing capability to perform grammar and semantic analysis. + + To abstract such different input method specific intermediate + information, TQt offers the TQInputContext as base class. The + concept is well known as 'input context' in the input method + domain. an input context is created for a text widget in response + to a demand. It is ensured that an input context is prepared for + an input method before input to a text widget. + + Multiple input contexts that is belonging to a single input method + may concurrently coexist. Suppose multi-window text editor. Each + text widget of window A and B holds different TQInputContext + instance which contains different state information such as + partially composed text. + + \section1 Groups of functions: + + \table + \header \i Context \i Functions + + \row \i Receiving information \i + x11FilterEvent(), + filterEvent(), + setMicroFocus(), + mouseHandler() + + \row \i Sending back composed text \i + sendIMEvent(), + + \row \i State change notification \i + setFocus(), + unsetFocus(), + reset() + + \row \i Context information \i + identifierName(), + language(), + font(), + isComposing(), + + \endtable + + + \section1 Sharing input context between text widgets + + Any input context can be shared between several text widgets to + reduce resource consumption. In ideal case, each text widgets + should be allocated dedicated input context. But some complex + input contexts require slightly heavy resource such as 100 + kilobytes of memory. It prevents quite many text widgets from + being used concurrently. + + To resolve such problem, we can share an input context. There is + one 'input context holder widget' per text widgets that shares + identical input context. In this model, the holder widget owns the + shared input context. Other text widgets access the input context + via TQApplication::locateICHolderWidget(). But the access + convention is transparently hidden into TQWidget, so developers are + not required to aware of it. + + What developer should know is only the mapping function + TQApplication::locateICHolderWidget(). It accepts a widget as + argument and returns its holder widget. Default implementation + returns the top-level widget of the widget as reasonable + assumption. But some applications should reimplement the function + to fit application specific usability. See + TQApplication::locateICHolderWidget() for further information. + + + \section1 Preedit preservation + + As described above, input contexts have wide variety of amount of + the state information in accordance with belonging input + method. It is ranging from 2-3 keystrokes of sequence in + deterministic input methods to hundreds of keystrokes with + semantic text refinement in complex input methods such as ordinary + Japanese input method. The difference requires the different reset + policies in losing input focus. + + The former simple input method case, users will prefer resetting + the context to back to the neutral state when something + happened. Suppose a web browsing. The user scroll the page by + scrollbar after he or she has typed a half of the valid key + sequence into a text widget. In the case, the input context should + be reset in losing focus when he or she has dragged the + scrollbar. He or she will be confused if the input context is + still preserved until focused back to the text widget because he + or she will restart typing with first key of the sequence as a + habitual operation. + + On the other hand, we should choose completely different policy + for the latter complex input method case. Suppose same situation + as above but he or she is using a complex input method. In the + case, he or she will be angry if the input context has been lost + when he or she has dragged the scrollbar because the input context + contained a valuably composed text made up by considerable input + cost. So we should not reset the input context in the case. And + the input context should be preserved until focused back to the + text widget. This behavior is named as 'preedit preservation'. + + The two policies can be switched by calling or not calling reset() + in unsetFocus(). Default implementation of unsetFocus() calls + reset() to fit the simple input methods. The implementation is + expressed as 'preedit preservation is disabled'. + + + \section1 Preedit relocation + + Although the most case of the preedit preservation problem for + complex input methods is resolved as described above, there is a + special case. Suppose the case that matches all of the following + conditions. + + \list + + \i a input focus has been moved from a text widget to another text + widget directly + + \i the input context is shared between the two text widgets + + \i preedit preservation is enabled for the input context + + \endlist + + In the case, there are the following two requirements that + contradicts each other. The input context sharing causes it. + + \list + + \i the input context has to be reset to prepare to input to the + newly focused text widget + + \i the input context has to be preserved until focused back to the + previous text widget + + \endlist + + A intrinsic feature named 'preedit relocation' is available to + compromise the requirements. If the feature is enabled for the + input context, it is simply moved to the new text widget with the + preedit string. The user continues the input on the new text + widget, or relocate it to another text widget. The preedit of + previous text widget is automatically cleared to back to the + neutral state of the widget. + + This strange behavior is just a compromise. As described in + previous section, complex input method user should not be exposed + to the risk losing the input context because it contains valuable + long text made up with considerable input cost. The user will + immediately focus back to the previous text widget to continue the + input in the correct text widget if the preedit relocation + occurred. The feature is mainly existing as safety. + + The feature properly works even if the focus is moved as + following. Input method developers are not required to be aware of + the relocation protocol since TQInputContext transparently handles + it. + + a text widget -> a non-text widget -> another text widget + + To enable the preedit relocation feature, the input context class + have to reimplement isPreeditRelocationEnabled() as returns TRUE. + The implementation requires that the preedit preservation is also + enabled since preedit relocation is a special case of the preedit + preservation. If the preedit relocation is disabled, the input + context is simply reset in the relocation case. + + + \section1 Input context instanciation + \section1 Input method switching + + \section1 Text widget implementor's guide + + Add following code fragment into createPopupMenu() to add input + method dependent submenus. + + \code + #ifndef TQT_NO_IM + TQInputContext *qic = getInputContext(); + if ( qic ) + qic->addMenusTo( popup ); + #endif + \endcode + + \sa TQInputContextPlugin, TQInputContextFactory, TQApplication::locateICHolderWidget(), TQApplication::defaultInputMethod() +*/ + + +/*! + Constructs an input context. + + holderWidget is set immediately after this constructor has been + returned on the X11 platform. +*/ +TQInputContext::TQInputContext( TQObject *tqparent ) + : TQObject( tqparent ) +{ + d = new TQInputContextPrivate; +} + + +/*! + Destroys the input context. +*/ +TQInputContext::~TQInputContext() +{ + delete d; +} + +#if defined(TQ_WS_X11) +/*! + \internal + Returns the owner of this input context.
