## Detailed Description

Provides keyboard event notification

## Property Documentation

### focus : bool

Holds `true` if the QKeyboardHandlers has focus.

Access functions:

bool | focus() const
void | setFocus(bool focus)

Notifier signal:

void | focusChanged(bool focus)

### sourceDevice : Qt3DInput::QKeyboardDevice *

Holds the keyboard device of the QKeyboardHandler. Without a valid device, the QKeyboardHandler won't receive any event.

Access functions:
