List of all members.

Public Member Functions
virtual int	SetFocus (anXWindow *w, clock_t time, int notifyonly)
virtual unsigned long	QueryModifiers ()
virtual int	clearReceiver (EventReceiver *receiver)
	Set current_focus to NULL if receiver->object_id==current_focus->object_id.
Public Member Functions inherited from Laxkit::LaxDevice
virtual const char *	DeviceName ()
	Default is just to return name.
virtual const char *	DeviceType ()
	Default just returns NULL.
virtual int	GetKey (int k)
	-1 returns number of buttons. Otherwise check status of that button number: return 1=on, 0=off.
virtual int	GetButton (int b)
	-1 returns number of buttons. Otherwise check status of that button number: return 1=on, 0=off.
virtual double	GetValue (int v, int w)
	-1 returns number of valuators. Otherwise check information of that valuator.
virtual int	numFields ()
virtual int	getFieldTypeInfo (int f, const char **nme, int *type, int *min, int *max, int *res)
	Retrieve device field info.
virtual int	usesX ()
	Return nonzero if the device gets messages through X.
virtual int	fd ()
virtual EventData *	getEvents ()
	Return an event stream if any events pending.
virtual int	eventFilter (EventData **events_ret, XEvent *xev, anXWindow *target, int &isinput)
	Turn an XEvent into EventData object(s).
virtual int	selectForWindow (anXWindow *win, unsigned long)
	Called after anXWindow::xlib_window exists, this sets up anything specific so the window gets related events.
virtual	~LaxDevice ()
	Empty virtual destructor.
virtual const char *	Name (const char *nname)
	Name the device.

Detailed Description

LaxDevice subclass for keyboards.

Todo:

*** XIM: x input context stuff is crazy! need either a good explanation with working examples, or some simpler system.

Member Function Documentation

int Laxkit::LaxKeyboard::SetFocus ( anXWindow *  w, clock_t  time, int  notifyonly  )

virtual

Remember that keyboard stores time as returned by times(), not Xlib time. If notifyonly, then this has been called in response to an event, not as a request to grab the focus.

Return 0 for focus changed. 1 for not changed, an error occured perhaps.

Reimplemented in Laxkit::CoreXlibKeyboard.
