A method to track input for tool events, thought it might be useful to others.

toolInput.cpp

void input_testing(ILxUnknownID vts)
{
	// setup
	CLxUser_VectorStack	 vec(vts);
	LXpToolInputEvent *input_event;

	input_event = (LXpToolInputEvent *)vec.Read(offset_input);

	// Tool Input Count(could be used to track number of clicks etc)
	int count = input_event->count;
	// Tracks whether tool is hauling
	int haul = input_event->haul;
	// Ouputs 0 or 1 for Left Mouse or Right Mouse respectively, <LXfTMOD_I0_INPUT> <LXfTMOD_I1_INPUT> both need to be set
	int input = input_event->input;
	// Outputs Different Numbers based on whether Ctrl, Shift or a Combination is held down.
	int mode = input_event->mode;
	// Test  for handle hitting.
	int part = input_event->part;
	// Not Sure what this is for, I think it shows type of tool, normal, brush etc.
	int type = input_event->type;

	//Output
	my_log.Info("Input Count: " + toString(count));
	my_log.Info("Input Haul: " + toString(haul));
	my_log.Info("Input Input: " + toString(input));
	my_log.Info("Input Mode: " + toString(mode));
	my_log.Info("Input Part: " + toString(part));
	my_log.Info("Input Type: " + toString(type));
