Detailed Description

Note: There is no binary compatibility guarantee for this class, meaning that an application using it is only guaranteed to work with the Qt version it was developed against.

Member Type Documentation

typedef QEglFSFunctions::LoadKeymapType

Function type for loadKeymap.

Member Function Documentation

[static] void QEglFSFunctions::loadKeymap(const QString &filename)

Loads and switches to the keymap from filename. When 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 -plugin argument, or when the environment variable QT_QPA_EGLFS_DISABLE_INPUT is set or when building Qt without evdev support, this function will have no effect.

[static] QByteArray QEglFSFunctions::loadKeymapTypeIdentifier()

Returns the identifier that can be passed to QGuiApplication::platformFunction() to query the entry point for the loadKeymap function implementation.

[static] void QEglFSFunctions::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 -plugin argument, or when the environment variable QT_QPA_EGLFS_DISABLE_INPUT is set or when building Qt without evdev support, this function will have no effect.
