I'm new to Flash Builder 4 and Actionscript 3 (actually, to programming as a whole beyond some very simplistic stuff). I have watched / read a bunch of tutorials, and started a project but now seem to have hit a wall. The answer is most likely simple, but seems to be alluding me.
How do I (or What approach should I take) to control visual elements, for instance, BorderContainer's, that I created dynamically?
As is, I have an Application containing a BorderContainer and a DataGrid. At runtime, 3 new BorderContainers (which are dragable, and resizeable) are created based on XML data that contains X & Y co-ordinates, and Height and Width values, and then added to the pre-existing BorderContainer. How would I go about getting the properties of these children BorderContainers to be displayed and remain up-to-date in the DataGrid (such as when they are moved/resized)?
I've got a problem with a (seemingly) simple equation that i can't quite figure out.
My problem is as follows:
I've got a pretty basic for loop that creates a 'thumbnail' and puts it next to the previous one (With a little padding) inside a containing movie clip.[code]...
I'm dynamically creating movieclips with dynamically created movieclips inside them and am having trouble with targeting them.Below is a simplified example of what I'm trying to achieve, in the real file there are a lot more movieclips and I'm creating and naming them with a for loop.
This one is just one Sprite created inside another sprite. I can target the top level sprite named "testname". However when i try target the nested MC it throws an error.The bottom couple of traces are just test MCs I've made to make sure i got the syntax right, on targeting nested movieclips.
PHP Code:
var holder:Sprite = new test1();holder.name = "testname";this.addChild(holder);var holder2:Sprite = new test2();holder2.name = "testname2";holder.addChild(holder2);trace(getChildByName("testname").x); //this one traces finetrace(getChildByName("testname").getChildByName("testname2").x);//this throws up an errortrace(testclip1.x);trace(testclip1.testclip2.x);
I am dynamically creating panels based on information i get from an XML file but i'm having a problem with adding buttons to these panels. These buttoms are also created based on information taken from the XML file. The problem seems to be in the way i give the panels an Id name.[code]...
I have some custom components, that derived from UIComponent. I overloaded the updateDisplayList so they have custom look. I've created a layouter that lays out these custom components, but to place them correctly, I have to know the custom componets width, height. They are created dynamically. After all of them created (creationCompleted event fired for every), i try to laying out them, but width/height property is still 0. I am also tried to add them to a canvas, before the layout process.
how to create custom UIComponent that placed dynamically, and get to know the width and height of it.
With the use of the mx_internal namespace I can set width and height (using the internal $width and $height fields), and it looks like it is working. But not so clean/good solution.
xml values are stored in 'arr' array collection. depending on the length of the array stored, the below described components are created and assign those values to relevant components dynamically. For Example:
I have problem with casting custom event currentTarget to component. When I'm trying to removeElement from its parent container i get error. What's the deal?
TypeError: Error #1034: Type Coercion failed: cannot convert mx.events::FlexEvent@8811c41 to com.modultek.pis.itemmachine.search.events.SortEvent. private function sortSelection_removeHandler(event:SortEvent):void { var sortSelection:SortSelection = event.currentTarget as SortSelection; this.removeElement(sortSelection); }
in FlashBuilder I want to dynamically generate approximately 1200 rectangles from a CSV file (these are all different colours) which will perform an action on Click.
What is the best way to go about doing this? I've read that the drawing API on Air and Android is not a good idea, and am thinking about using the Spark Rectangle class, but I can't seem to work out how to apply a colour to it if I'm generating them dynamically using AS?
My app has buttons that users press to insert predefined strings into a textarea. I'm now making it load in the button values dynamically so users can define their own buttons.I'm using a buttons.txt which contains a different label on each line (button1, button2,button3 etc). I loop through the text file and add the buttons to a group. This all works, but now the hard part. How can I assign an eventlistener to these buttons so that they output text to the screen?
protected function view1_viewActivateHandler(event:ViewNavigatorEvent):void { var path:File = File.documentsDirectory.resolvePath("buttons.txt");
I need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change.
I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.
When I create a tab dynamically via ActionScript, the style for the newly created (and selected) tab get applied to the skins, but not the text, unless I click on another tab and then click back to it.
I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob.
i.e.
private function prePrint():void { var printSelection:Box = new Box();
[Code]....
I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go.
I have an ArcGIS map created with Flex. The labels created dynamically are the towns on the map. We have some PDF files that have some information about the towns on the map.
Is there a way to make those town labels clickable so that they can display the PDF information on a new page?
I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
i created dynamically checkbox on data grid how do i find out Which checkbox select/unselect and which checkbox contact is select/unselect ? Because we cant set dynamic id for each checkbox
<fx:Script> <![CDATA[ import mx.controls.*; import mx.controls.TextInput; import mx.events.ListEvent; public function init():void { [Code] .....
I have implemented this one. I am getting 5 textboxes with empty value, if I entered some value in each textbox then, I want to get specific 3rd textbox value wen some event trigger.
I have several nested VBoxes in flex, and I'm aiming for one of them to get scrollbars if the total content is larger than the window height. However, when I grow the container, it doesn't get scrollbars at all (vertical scroll policy is AUTO), and the outer container stretches past the bottom of the screen, causing the entire app to get scrollbars. So it looks something like this:
Essentially, I've got a MC container that's created dynamically based off an XML file (basically for every <title></title> I've got, it makes a new "card"). Now within the context of each <title></title> grouping I've got <imgs></imgs> in which I specify the path to images that are related.All of that works perfectly, save for the external jpg files actually appearing on the stage. The MC I add them to does, but the external image doesn't.My problem is- I can't add the external images until they're completely loaded (or so it appears). The thumbnail BG I use is blank. So I know for a fact that the thumbnail BG isn't occluding the loaded thumbnails.
I have the following scenario: I create an HBox with a width of 1000000px (one million pixels of width). this big HBox is contained inside another small HBox that has a width of 1000 px
[Code]...
Inside this big HBox I create a bitmapFill of a simple image, its just a pattern of lines the problem is that the scrollBar of the small hbox doesnt work well, it just stops halfway, the thumb of the scrollbar keeps going, but the scrolling stops and the end of the big hbox is not beign reached. Here is the part of the code that makes the bitmapfill:
Is mx.containers.HDividedBox deprecated by some spark container in Flex 4.5? I'm new to Flex programming and can't find any spark replacement for it.I want to have 2 Lists separated by movable vertical bar.
[Flex 4] Float left or right in layouts or containers?i have a main container, that is dynamic, 100% width, and in it there are 3 components. one should be floating to left, to right and the other will be centered. how do i do that?
Is it possible to create Accordion with only the headers without adding any containers in it? Is there a way so that I can just create the Accordion with three sections with only labels?
Is there a way to link two Scroller containers in Adobe Flex? As in, when one scroller is modified, the same modifications will be reflected in a second scrolling container?What I am trying to do is have an image and label on different areas of the screen that are swipable, and when they are swiped/changed I want the same change to be reflected in the other Scroller container.
Here is my initial Scroller container with images that the label Scroller container should correspond to:
My problem is pretty simple: Flex containers do layout based on un-transformed children, and so rotated children are positioned as if there were no rotation, but then they're rotated around the top-left of that position. I've attached an image to show what I mean. Can I wrap the components in something? Or do I have to resort to custom components or fixed layouts? The image inlining doesn't look like it's working to me. Link to example image: [URL]
I have a panel and i have set minWidth and width for it. The code looks like this <s:Panel id="adg1" x="199" y="164" width="200" minWidth="300" title="Title"> Here the expected behaviour is width of the panel should be 300 since the minWidth > width,but the panel width is 200.I dont understand where i have went wrong.
i am trying to make a some groups within a predefined group at run time. i can make groups, the code is working fine. Now i have added two buttons in each group which is created in run time. now the problem is one of the button is x . the property of button should be when i click on it it should delete the very specific group in which it is built. please check out the code and tell me what additions should i make.
