特性文档编制

focus : bool

保持 true if the QKeyboardHandlers has focus.

访问函数：

bool	focus () const
void	setFocus (bool focus )

通知程序信号：

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.

访问函数：

Qt3DInput::QKeyboardDevice *	sourceDevice () const
void	setSourceDevice (Qt3DInput::QKeyboardDevice * keyboardDevice )

通知程序信号：

void	sourceDeviceChanged (QKeyboardDevice * keyboardDevice )
