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. +*/ |
