  • Adobe flex dateField

    - by JonoB
    I have some code as follows: private function onComboChange(evt:Event):void { var temp:Date = df_date.selectedDate; temp.date += 5; df_dateDue.selectedDate = new Date(temp); } In essence, I am trying to add 5 days onto the selected date in df_date, and put that date into df_dateDue. This fires off via an EventListener on a combobox. Both df_date and df_dateDue are dateFields. OK, so the first time that I run this, it works fine; df_date stays the same and df_dateDue is set to 5 days past df_date. However, the next time that I run it, df_dateDue increments by 10 days from df_date, the next time by 15, and so on. So, stepping through the code shows that somehow df_date has become linked to the temp var, and that the temp var is not resetting itself each time the function is called. Example: df_date = 01 Jan, df_dateDue = 01 Jan. Fire off the event, df_date = 01 Jan, df_dateDue = 06 Jan Fire off the event again. At this point, var temp = 06 Jan (even though df_date still shows 01 Jan), and df_dateDue is then set to 11 Jan Fire off the event again. At this point var temp = 11 Jan (even though df_date = 01 Jan), and df_dateDue is then set to 16 Jan What am I missing here?

  • Flex 3 Regular Expression Problem

    - by Tommy
    I've written a url validator for a project I am working on. For my requirements it works great, except when the last part for the url goes longer than 22 characters it breaks. My expression: /((https?):\/\/)([^\s.]+.)+([^\s.]+)(:\d+\/\S+)/i It expects input that looks like "http(s)://hostname:port/location". When I give it the input: https://demo10:443/111112222233333444445 it works, but if I pass the input https://demo10:443/1111122222333334444455 it breaks. You can test it out easily at http://ryanswanson.com/regexp/#start. Oddly, I can't reproduce the problem with just the relevant (I would think) part /(:\d+\/\S+)/i. I can have as many characters after the required / and it works great. Any ideas or known bugs?

  • Flex chart display with no datapoint

    - by Shah Al
    I need to display price of item for every date in the month. The chart can be Bar chart or plot chart. Question: Suppose there is no data available for 01/15/2010 then, Is there a way to display (01/15/2010) on x axis but no (bar or plot point) corresponding y axis point ? i.e. there will be a empty space between 2 bars or plot points. Currently i am using 0 , But 0 is a valid value. Let me know if such a display is possible.

  • dragging components in flex

    - by SuperString
    so I am trying to drag around some images in a canvas. I am adding eventlisteners to the components and calling startDrag() and stopDrag() to pick them up and stuff: component.addEventListener(MouseEvent.MOUSE_DOWN, component.startDrag) The problem is that it is selecting the image at its (0,0) location and not where I initially click on it. So there's a sudden "jump" when I click on the image. It is not smooth. I noticed that startDrag() has two default parameters, one of them is lockCenter and it is default to false. Maybe do I set it equal to true somehow? (I don't know how to pass arguments to my second parameter in addeventlistener) Another question: if I want to add more conditions to it, like make a new function that uses component.startDrag(), how do I pass the component to this function while adding event listener to it at the same time? for example: I want to do: component.addEventListener(MouseEvent.MOUSE_DOWN, some_other_function); where some_other_function uses component.startDrag(); Thanks!

  • Flex 3 - Image cache

    - by BS_C3
    Hello Community. I'm doing an Image Cache following this method: http://www.brandondement.com/blog/2009/08/18/creating-an-image-cache-with-actionscript-3/ I copied the two as classes, renaming them CachedImage and CachedImageMap. The thing is that I don't want to store the image after being loaded a first time, but while the application is being loaded. For that, I've created a function that is called by the application pre-initialize event. This is how it looks: private function loadImages():void { var im:CachedImage = new CachedImage; var sources:ArrayCollection = new ArrayCollection; for each(var cs in divisionData.division.collections.collection.collectionSelection) { sources.addItem(cs.toString()); } for each(var se in divisionData.division.collections.collection.searchEngine) { sources.addItem(se.toString()); } for each( var source:String in sources) { im.source = source; im.load(source); } } The sources are properly retrieved. However, even if I use the load method, I do not get the "complete" event... As if the image is not being loaded... How is that? Any help would be appreciated. Thanks in advance. Regards, BS_C3

  • Flex: CursorManager does nothing when `stage.mouseChildren = false`?

    - by David Wolever
    I've found that if I use the CursorManager to set a cursor — CursorManager.setBusyCursor() — then set stage.mouseChildren = false, the cursor set by CursorManager is replaced by the "default" mouse cursor the next time the mouse is moved. I'm setting stage.mouseChildren = false so that, while the mouse is being dragged, other "stuff" on the stage won't get mouse events (eg, so that mouse-over affordances aren't triggered if I'm in the middle of a drag). Is there some way I can work around this?

  • Flex 4 Button state in a HGroup

    - by chchrist
    Hi all, I have a HGroup with some buttons inside which is my application's menu. <s:HGroup id="nav"> <s:Button id="homeButton" label="Home" /> <s:Button id="showroomButton" label="Showroom" /> <s:Button label="Catalogue" /> <s:Button label="Offers" /> <s:Button label="My Account" /> <s:Button label="My Orders" /> </s:HGroup> What I want is when I click for example the #homeButton to change it's state to "over", become disabled and reset all other buttons to the "up" state. I've written this function private function resetNavState():void { for(var i:int = 0,ii:int = nav.numChildren-1;i<ii;i++) { Button(nav.getChildAt(i)).mouseEnabled = true; Button(nav.getChildAt(i)).skin.setCurrentState("up",true); } } And then on the homeButton click handler for example i use protected function homeButton_clickHandler(event:MouseEvent):void { resetNavState(); currentState = "home"; homeButton.skin.setCurrentState("over",true); homeButton.mouseEnabled = false; } I resets the states of the #nav buttons but it doesn't change the state of the pressed button. Any ideas? Thanx in advance

  • Flex HDividedBox prevent dragging

    - by Jeremy Mitchell
    I'd love to be able to prevent dragging of a HDividedBox's divider based on a condition. for example: <mx:HDividedBox id="hd1" liveDragging="true" dividerDrag="dividerDragHandler(event)"> <Canvas id="c1"/> <Canvas id="c2"/> </HDividedBox> private function dividerDragHandler(event:DividerEvent):void { if (_something 10) { event.preventDefault(); } } Any ideas how I can do something like that? And I'd rather not mess with the widths of the child canvases. Thanks.

  • Populating a Datagrid with variable number of columns and rows in Flex

    - by Rie Mino
    I am trying to figure out how to manage a Datagrid based on an XML object like this: <matrix rows="5" columns="5"> <column> <row>0.5</row> <row>0.21</row> </column> <column> <row>0.6</row> <row>0.9</row> </column> <column> <row>0.5</row> <row>0.5</row> </column> <column> <row>0.8</row> <row>0.4</row> </column> </matrix> I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates. Thanks in advanced for your help.

    I have a chart that the user is able to zoom into an area by setting the min and max of LinearAxis for the vertical and horizontal axis. When you are zoomed in and you want to view or hide one of the series the chart zooms out to the max and then back in. How do I get the chart to not zoom out when setting the visibility of the series?

  • [Flex] Caching canvas into ByteArray

    - by Eugene
    Task: (all in code, not visual) create a canvas, place into it some labels and draw some lines, then cache it as byteArray. The problem is that if I cache an object that is already drawed on the screen, it works great, but if I cache a canvas, that have been created few lines earlier, this results white image. Is there any solution to cache a display object, that was created in code, but not intended to be displayed at all?

  • Should I learn FLEX, is it a marketable enough?

    - by aceinthehole
    I haven been recently laid off and was considering what to learn in the down time while trying to get another job. I had heard that Adobe's FLEX was starting to become more in-demand, and have seen it increasingly on job postings. Has anyone else been successful (career wise) in learning FLEX? Is it worth spending time to learn FLEX to add a bullet point to a resume, and lead to a possible job or should time be spent else where?

  • flex data provider not working if XML has single node value or less

    - by Rees
    hello, i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. My test show that XMLListCollection does NOT work either. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

  • Flex: Method doesn't work when being called on parentDocument

    - by ChrisInCambo
    Hi, I wonder is anyone can look at this code and tell me why calling the removeSelectedChild works when called from the same document, but returns the following error when called from the child document/component. "ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller." <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" > <mx:Accordion id="myAccordion" width="100%" height="100%" selectedIndex="0"> <mx:Script> <![CDATA[ public function removeSelectedChild():void { myAccordion.removeChild(myAccordion.selectedChild); } ]]> </mx:Script> <mx:headerRenderer> <mx:Component> <mx:Button click="{ parentDocument.removeSelectedChild() }" /> </mx:Component> </mx:headerRenderer> <mx:HBox> <mx:Button click="{ removeSelectedChild() }" /> </mx:HBox> </mx:Accordion> </mx:Application> Clicking on the button in the child produces the expected result, whilst clicking on the header throws an error despite the fact they both call exactly the same method. Sorry that the example is a little contrived, this problem arose in a quite complicated view, which was using all kinds of custom components. This was the only way I could display it in a way that will be quick for you to compile and easy to focus on the real issue without background noise. I'm pulling my hair out on this one and would really appreciate it if anyone could help. Cheers, Chris

  • interactive (adding listeners to) DAE model in flex + papervision

    - by G. Matthieu
    I have a DAE model that is parsed into several parts. I am able to deal with them separately, such as changing their material or colour but I am having problems adding click or hover listeners over the children. For example, lets say I have a model of a kitty where each facial feature is a child. I want to be able to hover or click the features and have a window pop up explaining the feature. I've tried parsing the model and adding listeners but it doesn't seem to work. Thanks in advance! L
