///////////// 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.

///////////// Calendar AfterSelected Handler ///////////////////////
// It's triggered whenever a date gets fully selected.
// The selected date is passed in as y(ear),m(onth),d(ay)
// e is a reference to the triggering event object
// NOTE: DO NOT define this handler unless you really need to use it.
////////////////////////////////////////////////////////////////////
// function fAfterSelected(y,m,d,e) {}


///////////// 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.

// It's triggered after the calendar panel has finished drawing.
// NOTE: DO NOT define this handler unless you really need to use it.

////////////////// Calendar fIsSelected Callback ///////////////////////
// It's triggered for every date passed in as y(ear) m(onth) d(ay). And if 
// the return value is true, that date will be rendered using the giMarkSelected,
// gcFGSelected, gcBGSelected and guSelectedBGImg theme options.

////////////////// Calendar fParseInput Handler ///////////////////////
// Once defined, it'll be used to parse the input string stored in gdCtrl.value.
// It's expected to return an array of [y,m,d] to indicate the parsed date,
// or null if the input str can't be parsed as a date.
// NOTE: If NOT defined here, the engine will create one matching fParseDate().

////////////////// Calendar fFormatInput Handler ///////////////////////
// Once defined, it'll be used to format the selected date - y(ear) m(onth) d(ay)
// into gdCtrl.value.
// It's expected to return a formated date string.
// NOTE: If NOT defined here, the engine will create one matching fFormatDate().
