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_EGLFS_DISABLE_INPUT} is set or when building Qt without evdev support, this function will have no effect. */ /*! \fn int QEglFSFunctions::vsp2AddLayer(const QScreen *screen, int dmabufFd, const QSize &size, const QPoint &position, uint drmPixelFormat, uint bytesPerLine) \internal \preliminary */ /*! \fn bool QEglFSFunctions::vsp2RemoveLayer(const QScreen *screen, int id) \internal \preliminary */ /*! \fn void QEglFSFunctions::vsp2SetLayerBuffer(const QScreen *screen, int id, int dmabufFd) \internal \preliminary */ /*! \fn bool QEglFSFunctions::vsp2SetLayerPosition(const QScreen *screen, int id, const QPoint &position) \internal \preliminary */ /*! \fn void QEglFSFunctions::vsp2AddBlendListener(const QScreen *screen, void(*callback)()) \internal \preliminary */
