Function Documentation

void dmxBackendCollectEvents	(	DevicePtr	pDev,
		dmxMotionProcPtr	motion,
		dmxEnqueueProcPtr	enqueue,
		dmxCheckSpecialProcPtr	checkspecial,
		DMXBlockType	block
	)

Get events from the X queue on the backend servers and put the events into the DMX event queue.

void* dmxBackendCreatePrivate

(

DeviceIntPtr

pDevice

)

Create and return a private data structure.

References GETDMXLOCALFROMPDEVICE.

void dmxBackendDestroyPrivate

(

void *

private

)

Destroy the private data structure. No checking is performed to verify that the structure was actually created by dmxBackendCreatePrivate.

int dmxBackendFunctions	(	void *	private,
		DMXFunctionType	function
	)

Process DMXFunctionType functions. The only function handled here is to acknowledge a pending server shutdown.

References DMX_FUNCTION_TERMINATE.

void dmxBackendInit

(

DevicePtr

pDev

)

Initialized the backend device described by pDev.

References DMX_LOCAL_KEYBOARD, DMX_LOCAL_MOUSE, dmxBackendComputeCenter(), dmxBackendInitPrivate(), dmxBackendSameDisplay(), GETPRIVFROMPDEV, and _DMXScreenInfo::index.

void dmxBackendKbdGetInfo	(	DevicePtr	pDev,
		DMXLocalInitInfoPtr	info
	)

Get information about the backend keyboard (for initialization).

References dmxCommonKbdGetInfo(), dmxCommonKbdGetMap(), _DMXLocalInitInfo::focusClass, _DMXLocalInitInfo::freemap, _DMXLocalInitInfo::kbdFeedbackClass, _DMXLocalInitInfo::keyboard, _DMXLocalInitInfo::keyClass, _DMXLocalInitInfo::keySyms, and _DMXLocalInitInfo::modMap.

void dmxBackendLateReInit

(

DevicePtr

pDev

)

Re-initialized the backend device described by pDev (after a reconfig).

References dmxBackendComputeCenter(), dmxBackendInitPrivate(), dmxBackendSameDisplay(), dmxBackendUpdatePosition(), dmxGetGlobalPosition(), dmxInvalidateGlobalPosition(), and GETPRIVFROMPDEV.

void dmxBackendMouGetInfo	(	DevicePtr	pDev,
		DMXLocalInitInfoPtr	info
	)

Get information about the backend pointer (for initialization).

References _DMXScreenInfo::beHeight, _DMXScreenInfo::beWidth, _DMXLocalInitInfo::buttonClass, dmxBackendInitPrivate(), dmxCommonMouGetMap(), _DMXLocalInitInfo::map, _DMXLocalInitInfo::maxres, _DMXLocalInitInfo::maxval, _DMXLocalInitInfo::minres, _DMXLocalInitInfo::minval, _DMXLocalInitInfo::numButtons, _DMXLocalInitInfo::numRelAxes, _DMXLocalInitInfo::ptrFeedbackClass, _DMXLocalInitInfo::res, and _DMXLocalInitInfo::valuatorClass.

void dmxBackendProcessInput

(

void *

private

)

Called after input events are processed from the DMX queue. No event processing actually takes place here, but this is a convenient place to update the pointer.

References DMXDBG4, DMXDBG6, dmxScreens, dmxSync(), and GETPRIVFROMPRIVATE.

void dmxBackendUpdatePosition	(	void *	private,
		int	x,
		int	y
	)

This routine is called from dmxCoreMotion for each motion event. x and y are global coordinants.
