Is it Possible to Use MouseOver in DateChooser?

[ajwei810192]

Hi, Guys:

I am trying to create dynamic toolTips of event labels on a dateChooser. However, as I am working on this problem, I have run into a problem. I cannot seem to get the mouseOver or mouseOut function to work and have it provide me with the date I have just rolled over or out.



<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:Script>
<![CDATA[

import mx.events.CalendarLayoutChangeEvent;

private function useDate(eventObj:CalendarLayoutChangeEvent):void {
// Make sure selectedDate is not null.
if (eventObj.currentTarget.selectedDate == null) {
return
}

//Access the Date object from the event object.
var day:String= eventObj.currentTarget.selectedDate.getDay();
var date:String=eventObj.currentTarget.selectedDate.ge tDate();
var month:String= eventObj.currentTarget.selectedDate.getMonth() + 1;
var year:String= eventObj.currentTarget.selectedDate.getFullYear();

var wholeDate:String= (eventObj.currentTarget.selectedDate.getMonth() + 1) +
"/" + (eventObj.currentTarget.selectedDate.getDate() +
"/" + eventObj.currentTarget.selectedDate.getFullYear()) ;
}
private function useDate2(event:Event):void{
trace("On Over: " + event.currentTarget.selectedDate.getDay()); //Type Error #1009
}
private function useDate3(event:Event):void{
trace("On Out: " + event.currentTarget.selectedDate.getDay()); //Type Error #1009
}
]]>
</mx:Script>

<mx:DateChooser id="date1" mouseOver="useDate2(event);" mouseOut="useDate3(event);"
change="useDate(event)"/>
</mx:Application>


Instead, I get this error from the code I have provided: TypeError: Error #1009: Cannot access a property or method of a null object reference.

If I use event.currentTarget only, I only get the id value of my DateChooser, which is date1. Could anyone please give me some tips on what I have done wrong here?

Thanks for your help.

to answer your question yes you can use mouse over.

I think your problem come into play with the type of event you looking for in your functions:
private function useDate2(event:Event):void{
trace("On Over: " + event.currentTarget.selectedDate.getDay()); //Type Error #1009
}
private function useDate3(event:Event):void{
trace("On Out: " + event.currentTarget.selectedDate.getDay()); //Type Error #1009
}

try this instead
private function useDate2(event:MouseEvent):void{
trace("On Over: " + event.currentTarget.selectedDate.getDay()); //Type Error #1009
}
private function useDate3(event:MouseEvent):void{
trace("On Out: " + event.currentTarget.selectedDate.getDay()); //Type Error #1009
}

also just trace the event.toString() to see what the event is returning. if you are still having problems.

Hi, Guys:

I fiddled around with it more and made some slight progress, but I still could not get the calendar to spit out the date. Here is the latest code:


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" themeColor="#0EFF02">
<mx:Script>
<![CDATA[
private function useDate2(event:MouseEvent):void{
trace(event.target.name.toString());
trace("On Over: " + event.target.selectedDate.getDay()); //Type Error #1069
}
private function useDate3(event:MouseEvent):void{
trace(event.target.name.toString());
// trace("On Out: " + event.target.selectedDate.getDay()); //Type Error #1069
}
]]>
</mx:Script>
<mx:Canvas id="test" x="118" y="136" width="443" height="133" >
<mx:DateChooser id="date1"
mouseOver="useDate2(event)"
backgroundColor="#FFFFFF" mouseOut="useDate3(event);"/>
</mx:Canvas>
</mx:Application>


And, here is the sample output of the trace() that is working:

UITextField56
UITextField56

If I un-comment out the line

trace("On Over: " + event.target.selectedDate.getDay());

I get the following error:

ReferenceError: Error #1069: Property selectedDate not found on mx.core.UITextField and there is no default value.

Does anyone know what this means and how I might be able to fix it?

Thanks for your help.
