First off, I have (almost?) no coding knowledge at all.
I'm using buttons to select a previous/ the next row, and am trying to loop the selection when it reaches either end of the list. The next button is working for me; it loops back to the beginning when the selection reaches the last row, but the previous button does not loop at all. How do I select the last row in the list?

Here is my function:

Code:

function prevMarble() {
   %id = List.getSelectedId();
   %maxinlist = List.rowCount();  //isn't working
   if (%id > 0)
       List.setSelectedById(%id--);
   else
       List.setSelectedRow(%maxinlist);
   updatemarbleobj();
}

Row indices start at 0, so the index of the last row would be (rowCount - 1).
So you'd want something like:

Code:

...
   if (%id > 0)
       List.setSelectedById(%id--);
   else
       List.setSelectedById(%maxinlist - 1); //Also changed to setSelectedById
...

Let me know if you have any problems.

This signature is real code

Code:

function clientcmd12dothepq() {
    commandToClient(LocalClientConnection, '34onthedancefloor');
}

Just wanted to chime in and say use .setSelectedById() method for both the if and the else clause. It might have worked the way you did it, but keep consistency.
