Problems when using IME in WPF by Contact DevExpress

Hello,

When working with IME from WinAPI, it's possible to get different information about IME Composition String using the ImmGetCompositionString function.

A program can retrieve the following attributes of the composition string (see http://msdn.microsoft.com/en-us/library/windows/desktop/dd318553(v=vs.85).aspx and http://msdn.microsoft.com/en-us/library/windows/desktop/dd318164(v=vs.85).aspx):

GCS_COMPCLAUSE - Retrieve or update clause information of the composition string.

GCS_COMPREADATTR - Retrieve or update the attributes of the reading string of the current composition.

GCS_COMPREADCLAUSE - Retrieve or update the clause information of the reading string of the composition string.

GCS_COMPREADSTR - Retrieve or update the reading string of the current composition.

GCS_COMPSTR - Retrieve or update the current composition string.

GCS_CURSORPOS - Retrieve or update the cursor position in composition string.

GCS_DELTASTART - Retrieve or update the starting position of any changes in composition string.

GCS_RESULTCLAUSE - Retrieve or update clause information of the result string.

GCS_RESULTREADCLAUSE - Retrieve or update clause information of the reading string.

GCS_RESULTREADSTR - Retrieve or update the reading string.

GCS_RESULTSTR - Retrieve or update the string of the composition result.


But in WPF we can only use TextCompositionManager and get only GCS_COMPSTR and GCS_RESULTSTR information from TextCompositionEventArgs. As a result, we can't implement custom IME for the Japanese language.

Please, add additional information to the TextCompositionEventArgs class.
