Get the actual thesaurus language

[Joel Cordeiro-2]

Hi,

does anyone know how to get the actual language of the thesaurus with the
api? I would like to show automatically the synonyms of the selected word on
the context menu. Actually i am just working with the portuguese language,
but i would like to make a generic extension, so it uses the language that
is selected on the thesaurus. Is that possible? I just know how to get all
the languages that exists for the thesaurus, and cannot find how to get the
selected language.

Regards,
Joel Filipe Antunes Cordeiro

the language is not "selected on the thesaurus", rather when you press
Ctr + F7 (or Tools - Language - Thesaurus), the language of the
thesaurus displayed in the dialog will depend on the language of the
word where the view cursor was inserted. The same goes for the context
menu when you right click on a spelling error.

So you need to know the language of the selected text/ the word where
the insertion point is: the language is retrieve as a character property
(http://api.openoffice.org/docs/common/ref/com/sun/star/style/CharacterProperties.html#CharLocale)

in the form of a com.sun.star.lang.Locale struct:
