///////////// Calendar Onchange Handler ////////////////////////////
// It's triggered whenever the calendar gets changed to y(ear),m(onth),d(ay)
// d = 0 means the calendar is about to switch to the month of (y,m); 
// d > 0 means a specific date [y,m,d] is about to be selected.
// e is a reference to the triggering event object
// Return a true value will cancel the change action.
// NOTE: DO NOT define this handler unless you really need to use it.

// It's triggered whenever a date gets fully selected.
// The selected date is passed in as y(ear),m(onth),d(ay)

///////////// Calendar Cell OnDrag Handler ///////////////////////
// It triggered when you try to drag a calendar cell. (y,m,d) is the cell date.

// aStat = 2 means a mouseup is detected (dragend)
// e is a reference to the triggering event object
// NOTE: DO NOT define this handler unless you really need to use it.
