<P>
<p>The <a href="QInputContext.html#QInputContext(com.trolltech.qt.core.QObject)"><tt>QInputContext</tt></a> class abstracts the input method dependent data and composing state.</p>
<p>An input method is responsible to input complex text that cannot be inputted via simple keymap. 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.</p>
<p>To abstract such different input method specific intermediate information, Qt offers the <a href="QInputContext.html#QInputContext(com.trolltech.qt.core.QObject)"><tt>QInputContext</tt></a> 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.</p>
<p>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 <a href="QInputContext.html#QInputContext(com.trolltech.qt.core.QObject)"><tt>QInputContext</tt></a> instance which contains different state information such as partially composed text.</p>
