For instance, a certain entry widget might be expected to contain -certain characters which would be easier to input with a certain input -method. -</p> -<p> -An input method may consume multiple key events in sequence and finally -output the composed result. This is called preediting, and an input method -may provide feedback about this process by displaying the intermediate -composition states as preedit text. For instance, the default GTK+ input -method implements the input of arbitrary Unicode code points by holding down -the Control and Shift keys and then typing "U" followed by the hexadecimal -digits of the code point. When releasing the Control and Shift keys, -preediting ends and the character is inserted as text. Ctrl+Shift+u20AC for -example results in the € sign. -</p> -<p> -Additional input methods can be made available for use by GTK+ widgets as -loadable modules.
