// 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.

///////////// Calendar Cell OnDrag Handler ///////////////////////
// It triggered when you try to drag a calendar cell. (y,m,d) is the cell date. 
// aStat = 0 means a mousedown is detected (dragstart)
// aStat = 1 means a mouseover between dragstart and dragend is detected (dragover)
// 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.

// NOTE: If NOT defined here, the engine will create one that checks the gdSelect only.
