Mutually Exclusive With Arrays

rolo · April 2006

I have a button array and a device array.

In this particular case , these buttons are for navigation between rooms.

Obviously I cannot have 2 rooms selected at once on a panel.

My statement will read something like this...

DEFINE_DEVICE
dvTP_1=128:1:1

DEFINE_CONSTANT

INTEGER nBtnArray_RoomNav[]={3001,3002} //Array For Navigation Button Numbers
DEV dvAllTP[]={dvTP_1} //Array For Touchpanels

DEFINE_EVENT

BUTTON_EVENT [dvAllTP,nBtnArray_RoomNav]
{
Push:
{
Do Whatever
}

}

How do I define the arrays' buttons as mutually exclusive?

Thanks

One way:

BUTTON_EVENT [dvAllTP,nBtnArray_RoomNav]
{
  Push:
  {
    STACK_VAR INTEGER nIND
    STACK_VAR INTEGER nBTN
    nIND = GET_LAST(dvAllTP)
    nBTN = GET_LAST(nBtnArray_RoomNav)
    ON[dvAllTP[nIND],nBtnArray_RoomNav[nBTN]]
  }
}

And then set up your MUTUALLY_EXCLUSIVE.

DEFINE_MUTUALLY_EXCLUSIVE
([dvAllTP[1],nBtnArray_RoomNav[1]]..[dvAllTP[1],nBtnArray_RoomNav[LENGTH_ARRAY(nBtnArray_RoomNav)]])

But I personally wouldn't even go that route. I would set up a variable that kept track of which room the panel was on, then set the feedback down in DEFINE_PROGRAM. You could easily do something like this:

DEFINE_VARIABLE
nCUR_ROOM[x] // x = THE NUMBER OF TOUCH PANELS

DEFINE_EVENT
BUTTON_EVENT [dvAllTP,nBtnArray_RoomNav]
{
  Push:
  {
    STACK_VAR INTEGER nIND
    STACK_VAR INTEGER nBTN
    nIND = GET_LAST(dvAllTP)
    nBTN = GET_LAST(nBtnArray_RoomNav)
    
    nCUR_ROOM[nIND] = nBTN
    // DO REST OF BUTTON PUSH STUFF
  }
}

DEFINE_PROGRAM
[dvAllTP[1],nBtnArray_RoomNav[1]] = (nCUR_ROOM = 1)
[dvAllTP[1],nBtnArray_RoomNav[2]] = (nCUR_ROOM = 2)

This way, if you ever need to know which room a panel is controlling, you can run conditionals / evaluations, etc. on this information.

This also works, using the buttons themselves as feedback:

BUTTON_EVENT[dvaTPs,nNavBtns]					// Navigation
{
	PUSH:
	{
		STACK_VAR INTEGER nPnlIdx ;
		STACK_VAR INTEGER nBtnIdx ;
		STACK_VAR INTEGER nLoop ;
		
		nPnlIdx = GET_LAST( dvaTPs )
		nBtnIdx = GET_LAST( nNavBtns )
		
		FOR(nLoop = 1; nLoop <= LENGTH_STRING( nNavBtns ); nLoop++)
			OFF[dvaTPs[nPnlIdx],nNavBtns[nLoop]]
		
		ON[dvaTPs[nPnlIdx],nNavBtns[nBtnIdx]]
	}
}

But like James said it's nice to have a var tracking your selections because the buttons will turn off if the panel goes offline (which is actually a benefit in some situations).
