|
|
*
|
|
* Functions that operate on Ecore Input Method Context objects.
|
|
|
|
* Ecore Input Method Context Function defines the interface for EFL input methods.
|
|
* An input method is used by EFL text input widgets like elm_entry
|
|
* (based on edje_entry) to map from key events to Unicode character strings.
|
|
*
|
|
* The default input method can be set through setting the ECORE_IMF_MODULE environment variable.
|
|
* eg) export ECORE_IMF_MODULE=xim (or scim or ibus)
|
|
*
|
|
* 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.
|
|
*
|
|
* Immodule is plugin to connect your application and input method framework such as SCIM, ibus, and so on.@n
|
|
* ecore_imf_init() should be called to initialize and load immodule.@n
|
|
* ecore_imf_shutdown() is used for shutdowning and unloading immodule.
|
|
*
|
|
* An example of usage of these functions can be found at:
|
|
* @li @ref ecore_imf_example_c
