+    This property holds whether the TextEdit has partial text input from an

+
+    While it is composing an input method may rely on mouse or key events from
+    the TextEdit to edit or commit the partial text.  This property can be used
+    to determine when to disable events handlers that may interfere with the
+    correct operation of an input method.
