问题 I am stuck with a requirement to display a horizontal line on a ColumnChart to indicate a threshold level. I have the data to the Chart as an ArrayCollection . So my question here : Is it possible to get the location of a value that is shown on the y axis? I think I will be able to place a line or 1px high canvas on top of the Chart to achieve this. Or better, is there any built in functionality that i may have overlooked or is there some open library that can achieve something like this? 回答1

问题 I want to set value of a progress bar in an accordian but I am encountering 'setProgress is not a function' error. Any idea what's wrong with following code. Observation: If I move the progress bar out of the Accordian then the error goes away and the progress bar appears fine. I want to set the progress bar eventually to {repMonitor.currentItem.threatLevel} but for now I am just testing with hypothetical threat value i.e 60 <mx:Accordion id="monAccordian" includeIn="Monitoring" x="10" y="10"

问题 When working with Date() objects in Flex/Actionscript, I'm using to following function to check for null dates. Is this the proper way to check for a null date or is there a better alternative out there? public function IsDateNull(date:Date):Boolean { if (date && date.fullYear != 0) { return true; } return false; } 回答1: Since Date is a class that extends Object and isn't a primitive type it doesn't have a default value and therefore should only be null if it hasn't yet been instantiated.

问题 After asking "Do certain characters take more bytes than others?", I figured out that I'd need to set the character encoding set when receiving and sending data with a socket connection in Actionscript / Flex 3. Now I've been trying to find out how to do this, however there doesn't seem to be such property available.
