  • Find Upper Right Point of Rotated Rectangle in AS3 (Flex)

    - by coltech
    I have a rectangle of any arbitrary width and height. I know X,Y, width, and height. How do I solve the upper right hand coordinates when the rectangle is rotated N degrees? I realized if it were axis aligned I would simply solve for (x,y+width). Unforunatly this doesn't hold true when I apply a transform matrix on the rectangle to rotate it around its center.

    - by charlielee
    Hi, I have a component that were exported from catalyst (the component is based on a tag). Now I created a new component extending this. However when I add this new component to my module it doesn't seem to inherit the designs that were exported from catalyst. Any idea how i can do that? Ofcource when I add the component that were directly out of catalyst all the designs appears.. Thanks.

  • Flex: Problem with CollectionEvent on ArrayCollection

    - by dasnervtdoch
    Hi there, got a reference to an arrayCollection and add event listener like this: collection.addEventListener(CollectionEvent.COLLECTION_CHANGE, onCollectionChange); that´s fine. Now some other component does have the same reference and is adding items to and removing items from that collection. Each time the handler is called: private function onProjectPersonsChange(event:Event):void { if (event.kind == CollectionEventKind.ADD) { //do something } else if (event.kind == CollectionEventKind.REMOVE) { //do something //here is the problem: event.items.length = 0 } else { trace('CollectionEvent: kind not handled!'); } } Does somebody know why the removed item is not in 'items'? Thanks in advance!

  • FLEX: How to know when a dialog created throw PopUpManager Closes

    - by WeeJavaDude
    Is there a easy way to figure out consistently when a Dialog closes that has been created through PopUpManager. I would have suspected some type of message or callback mechanism, but there does not seem to be. In one case I use the WindowTitle component and event that only fires the CLOSE if someone presses the close and give no message when the dialog actually closes.

  • [FLEX 3] Placing images into a Collage Canvas

    - by Bridget
    I've got an array of different sized images. I want to place these images on a canvas in a sort of automated collage. Does anyone have an idea of how to work the logic behind this concept? All my images have heights divisible by 36 pixels and widths divisible by 9 pixels. They have mouseDown functions that allow you to drag and drop. When dropped the image goes to the closest x point divisible by 9 and y point divisble by 36. There is a grid drawn on top of the canvas. I've sorted the array of images based on height, then based on their widths. imagesArray.sortOn("height", Array.NUMERIC | Array.DESCENDING); imagesArray.sortOn("width", Array.NUMERIC | Array.DESCENDING); I'd like to take the largest image ( imageArray[0] ) to put in corner x,y = 0,0. Then randomize the rest of the images and fit them into the collage canvas.

  • [FLEX] MVC: choosing a view at runtime

    - by Alberto M
    Hi all, I'm quite new to the MVC design-pattern, and I'm translating all of my old code. I want to move to this pattern because I can change my views according to my needs, but I'm finding difficult to do it at runtime. I found an excellent example of MVC, and all that I do is the following: <mx:ViewStack xmlns:mx="http://www.adobe.com/2006/mxml" resizeToContent="true" xmlns:views="MVC.views.*"> <views:HomeView id="Home"/> <views:SecondPage id="SecondPage "/> </mx:ViewStack> what if I wanted to change (whenever the Controller says so) one of the views, for example the SecondPage view? (Hope I made my point clear)

  • Flex list-controls - maintain remote data

    - by artemb
    Hello. I have a TileList which represents some remote data. I also have a form which allows me to change the data. And the data may be changed by someone else too. What is the best way to maintain data in the list in an up-to-date state? The simplest option I see is the following: Select an item in the list Edit it in the form Save it. The form submits the data to the server When the server reports success the list re-fetches it's data The very bad thing about this workflow is that the list loses selection (a tree would also loose the nodes' expanded/collapsed state). I would really love to find out another option which would enable the list to maintain it's selection state. Any guesses on how it may be done?

  • Actionscript flex: Converting # colors to uint

    - by Daryl
    I'm working with several components that take color as a uint, but the colors I have are in the format of "#161616". I'm not sure what the relation between the 2 types of colors are or how to go from one to another. It doesn't have to be an actionscript solution. I have only a small number of these colors, so can be done manually too.

  • FLEX: how to ignore MouseEvents from the container ?

    - by Patrick
    hi, I've some objects on the canvas, and I added eventListeners to these objects for MOUSE_UP event. I'm know checking if it works by tracing e.target.name, and I found out that the event is triggered twice, before on the element container (Canvas) and then the element itself. I read several times the documentation about Capture, Bubbling etc.. but I don't understand how to trigger the events only from the element itself... child.addEventListener(MouseEvent.MOUSE_UP, updateSelectedTags); private function updateSelectedTags(e:MouseEvent):void { Alert.show(e.currentTarget.name); //I have 2 alerts, one for canvas, the other one for the child } } thanks

  • Flex Setting form height dynamically

    - by Daryl
    I'm not sure if this is possible, is there a way to get the <mx:Form> to set its own height based on the position of an element within it? For example something like this: <mx:Form height="{submitBtn.y + submitBtn.height}"> <mx:FormItem>... </mx:FormItem> <mx:FormItem>... </mx:FormItem> <mx:FormItem>... </mx:FormItem> <mx:FormItem> <s:Button id="submitBtn" label="Submit" /> </mx:FormItem> </mx:Form> where the form height is dynamically set based on submitBtn's y position and its height. I tried using Alert.show to show these values and turned out submitBtn.y = 0 and submitBtn.height = 21. height sounds reasonable, but I know the y of submitBtn can't be 0 since it's below several other Is it possible to set the form height dynamically?

  • flex accessing children of a list component

    - by pfunc
    when I try to loop through the children of a List component that has buttons in it, I can't seem to access those children. I try for(var btnNum:Number = 0; btnNum < myList.numChildren; btnNum++) { trace(myList.getChildAt(btnNum); } but it is giving some other instance, not the button instances. and the weeklist <mx:List id="myList" dataProvider="{_data.mappoints.week.@number}" > <mx:itemRenderer > <mx:Component> <mx:Button buttonMode="true" toggle="true" alpha="1" width="116" height="35" label="WEEK {data}" > </mx:Button> </mx:Component> </mx:itemRenderer> </mx:List>

  • Flex - Use Variables for Object Attribute Names

    - by Immanuel
    How do you use variables to access Object attributes? Suppose I have an Object declared as follows, var obj:Object = new Object; obj.Name = "MyName"; obj.Age = "10"; How would i do something like this, var fieldName:String = "Name"; var fieldAge:String = "Age"; var Name_Age:String = obj.fieldName + " ," + obj.fieldAge; The code above treats 'fieldName' and 'fieldAge' as attribute name itself. I want to treat the same as a variable, and map the value associated with the variable as the Object attribute name.
