Class to hold info about various input devices.

These might be knobs, midi devices, or perhaps wiimotes.

Todo:: maybe have default device objects for LaxMouse, LaxKeyboard, Touchpad, MultiTouchPad, Midi, Wiimote

Member Function Documentation

int Laxkit::LaxDevice::clearReceiver ( EventReceiver * receiver )

virtual

Remove all reference to receiver.

Return 0 for successful clearing, or nonzero for error or not found.

Reimplemented in Laxkit::LaxKeyboard, and Laxkit::LaxMouse.

int Laxkit::LaxDevice::eventFilter	(	EventData **	events_ret,
		XEvent *	xev,
		anXWindow *	target,
		int &	isinput
	)

virtual

Turn an XEvent into EventData object(s).

Return 1 if event is absorbed, and nothing else should try to parse it. Use the returned EventDatas instead. Return 0 if event is ignored.

Reimplemented in Laxkit::CoreXlibKeyboard, and Laxkit::CoreXlibPointer.

Referenced by Laxkit::DeviceManager::eventFilter().

int Laxkit::LaxDevice::getFieldTypeInfo	(	int	f,
		const char **	nme,
		int *	type,
		int *	min,
		int *	max,
		int *	res
	)

virtual

Retrieve device field info.

nme is a name describing the field, such as "Keys", "Buttons", or "Pressure".

Type can be 0 for key, 1 for button, 2 for value.

For keys, min and max are the min and max keycodes.*** really? For buttons, min is 0, and max is the number of buttons available. For values, returns the minimum value, maximum value, and resolution of the value.

Return 0 for successful return of info, else 1 for info not available.

double Laxkit::LaxDevice::GetValue	(	int	v,
		int	w
	)

virtual

-1 returns number of valuators. Otherwise check information of that valuator.

w=0,1,2=value, min, max

int Laxkit::LaxDevice::numFields ( )

virtual

Return -2 if unititialized, -1 field type info not available

int Laxkit::LaxDevice::selectForWindow	(	anXWindow *	win,
		unsigned	long
	)

virtual

Called after anXWindow::xlib_window exists, this sets up anything specific so the window gets related events.

Return 0 for successful selection, nonzero for nothing done.

Reimplemented in Laxkit::CoreXlibKeyboard, and Laxkit::CoreXlibPointer.

Referenced by Laxkit::DeviceManager::selectForWindow().
