When \a filename is empty, the default keymap, which is either the built-on one or the keymap given in the plugin specification, is restored. \note This is functional only when the evdev keyboard support code is compiled in to the platform plugin. When using external generic plugins via the \c{-plugin} argument, or when the environment variable \c{QT_QPA_FB_DISABLE_INPUT} is set or when building Qt without evdev support, this function will have no effect. */ /*! \fn void QLinuxFbFunctions::switchLang() Switches between English and other language when the keymap is loaded. Usually the keymap contains two languages: English and national. When you load the keymap, English is selected by default. This function allows to switch between these languages. \note This is functional only when the evdev keyboard support code is compiled in to the platform plugin. When using external generic plugins via the \c{-plugin} argument, or when the environment variable \c{QT_QPA_FB_DISABLE_INPUT} is set or when building Qt without evdev support, this function will have no effect. */
