Hi GuruRamesh,
If you already have the extended virtual keaboard and Pinyin input, you can add a global input state handler, eg. an AutoObject.
Here you can attach observers from your applicaiton or from any instantiated TextInput to get informed about the input state setting.
This setting can be changed when pressing the globe burron within the extended virtual keyboard or from any other setting, like a menu.
With kind regards,
Rudolf
