I need to load several images as Bitmap or BitmapData objects. The images are hosted outside the Flex project, and they're referenced by an external configuration file, so I can't embed them. Because the images won't be displayed directly to the user (they're being added to a PDF that is generated for download), creating a grouping of Image objects, attaching them to the application, and waiting for their LoadComplete handler to fire seems inefficient.
What is the best way to load these images into an application? Programatically load images in it?
I'm developing an Blackberry Playbock app with ActionScript 3.0. I'm very very new with this. I have the following project structure (I'm using Adobe Flash Builder "Burrito"): project
[Code]...
On image folder I have several PNGs images that I want to load programmatically.
I'm building a slide-show like application in Flex and I'm trying to load images dynamically. The images are in a folder outside the application folder. This is the folder structure:
In my application, I make numerous calls to preload images to brower cache in the background using Loader instances and ignore the complete event. I don't store the results in the application, but rather want to store them in the browser cache. The images have long Expires header dates.
When I want to use a particular image(s), I again use a Loader instance and call the same url and listen for the complete event to load the file to an Image.
The problem is that when I re-request the url for the "cached" image, it is making an http request with response 200 status, which I presume means it is hitting the server. How do I make sure that a request for a cached image never hits the server from Flex? I am finding that any request to a url for a cached image (with a long expires header) is making another request to the server, or at least that is my interpretation of it in Firebug.
i am working in flex and in flash builder 4. Now my requirement was, i want to display images inside datagrid. I found a solution in mxml when searching in net. But i need a solution in actionscript. i am attaching the mxml code along with this.
I'm trying to load a bunch (about 100) of images into memory, so I can display them at various times. Originally I had simply embedded them, but that of course resulted in the swf file being larger than I wanted. So now I'm trying to change it to load them in the background because they aren't needed immediately.There are probably plenty of problems with this. The current on is that I'm getting an error that says 'TypeError: Error #1034: Type Coercion failed: cannot convert "foo.jpg" to Class.'
I've been googling this awhile, assuming loading an external image is a common thing. That's where I got the Loader and URLRequest code, but I'm clearly missing something. Maybe it's due to my goofy looping logic.Here's the class so far
public class CardImages2 { public static var fooImage1:Class;[code]....
So I made a drag and drop app where I can drop in an image, it get's resized and saved automatically on the desktop.
But now I want to do the same when there are multiple images dragged in. This is where I'm stuck...
private function onDrop(e:NativeDragEvent):void { trace("Dropped!"); var dropfiles:Array = e.clipboard.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;
[Code]....
The problem is that I want the completeHandler() to run after every ldr.load() but in my code it only runs once right after the for each loop.
I have a spark skinnable component which contains a datagroup with images. The datagroup is scrolled by hovering the mouse over it. Everything works fine except one thing: after I change the datagroup provider, I need to scroll down automatically. The problem is the images are not loaded immediately after I set the provider so (contentHeight - height) does not yet represent the actual maximum scrolling position. Is there an easy way of telling the datagroup to scroll down as its content loads? Because the workaround seems to be not so straightforward. This is the code for scrolling(thumbnailStrip is my datagroup):
I have a flashbuilder project with a big image. The problem is that the default preloader does not load the images/swf's inside the project. Is there a way to preload them?
I'm using a dateField component (with editable = true) as an itemEditor in a dataGrid. Interestingly, when editing the textInput part of the dateField it doesn't seem to react to an ESC keydown as I would expect, i.e. reload old dateField value and give up focus. This seems to be standard for most other components, but not for as most other components do.
How would you go about implementing such behavior? I can listen to keydown == escape on the TextInput portion, but just realized that I don't know how to tell dateField to give up focus and politely close - in fact I'm not even sure that's the right strategy (maybe I should work at the DataGrid level?
I have I datagrid, on which I want to select multiple rows on a other user interaction than the one intended by the Programm. I'm wondering, whether I can programmatically select some rows depending only on code?
how can I assign the stroke to my LineSeries, programmatically in Actionscript ?<mx:LineSeries stroke="{new Stroke(0xCC33CC, 2)}"/>How is it in Actionscript? LineSeries.stroke doesn't exist
I'm trying to figure out how to in as3 (not mxml) add views to a view stack.For example I have a view component like so[code]I've being trying to add it to a viewstack in the following way.[code]I'm aware I have to assign ID's but for now I just want to get the view in there
I would like to know the correct way to close an AIR application programmatically. In my Spark WindowedApplication I have:this.addEventListener( Event.CLOSING, shutdownApp );and of course an implementation of the shutdownApp method (which basically tidies up temporary files).his works fine for the top-right close button of the window. However I also have functionality which needs to shutdown the application. Within the code I have called:NativeApplication.nativeApplication.exit();However this doesn't trigger the Event.CLOSING method, and so my temporary files are not cleared up. Should I not be calling nativeApplication.exit ? If so, what should I call instead? I'd rather not have to call my shutdownApp method before the NativeApplication.exit() as this doesn't feel quite so elegant.
I have various components that are skinned through a programmatic skin. The skin class references a singleton class that holds various colors to be applied to different aspects of the component. The singleton class has default colors set to variations of black/grey etc. I'm loading in custom colors from an XML file that are then loaded into the singleton. I'm applying the custom skin through a css stylesheet that is included in the main Application mxml.
The problem is that when the swf initially loads, the components that are drawn on screen are black and don't reflect the changes in color loaded from the XML file. I have some dropdown windows that show on button clicks and those dropdowns do reflect the correct colors from the XML file. Therefore, the system is working correctly, but the initial drawing of components obviously happens before the XML is loaded and applied to the singleton.
My question is, is there a way to apply a skin to an element programmatically by calling the constructor?
or something to that effect? This way, I can remove the loading of the skins in the css file and control when they are instantiated to ensure that the correct colors are applied before displaying the various components.
I'm developing an application for the Blackberry Playbook using Flash Burrito 4.5 and Flex. I'd like to create a file browser to allow users to load images from the local system into the application. I followed this example [URL] When I click on the Load Image button in the simulator however, the file browser pops up but tells me that "no file was found with the specified filter", even though I don't specify any filter or even if I specify a . filter.
In Flex you can stream microphone audio to an FMS/Red5 server using NetStream.attachAudio, which requires a Microphone object. Is it possible to stream audio through the NetStream from somewhere other than a Microphone? For example, from a file/embedded resource?
The reason I'm asking is that I'd like to be able to run automated tests that don't require using an actual microphone.
I have a question I came up with 3 days ago about how to do the blue underlining of a datagrid row programmatically. I thought to have found the solution, with just adding the column and row Indexes to the datagrids editedItemPosition Property.It turned out, that this is just practical if you want to be able to edit the grids row right away. But what if I just want to underline it with the blue color?Additionally how to detect that a list based Item got this kind of selection? es there a event to detect that? whats the name of this kind of selection?
I created an application as part of an ASP.NET site. I would like to receive error notifications in my inbox whenever something goes wrong with that flash application.As I do not have control over our mail server (which has a different domain name), I cannot establish a cross domain policy allowing me to send error emails to my inbox.Instead, thought I'd send a request to an ASP.NET handler that sends an email on behalf of the flash app.Now the problem: the error report should include a screenshot of the flash application at the time the error occurred. The FileReference class however only allows file uploads with user interaction (browse dialog) and cannot be used programmatically to send the screenshot to my ASP.NET handler. The plain old POST back only allows files up to ~200K.
How to programmatically enlarge a flex 3 button's hitArea. Is there some function that I can override? There is no function in the button class called hitArea. What I have done is, I have created a programmaticskin for a button. The form of the skin consists out four arrows. In between the arrows there is nothing (meaning transparent). Because of the way the skin is shaped, it's difficult to click on the button. The skin has alter the buttons hitArea. What I'm looking for is a way to enlarge the hitArea and alter the hitArea shape in to an square. (the hit area must ofcourse still be invisible).
I have a chart with 2 line series in it.So, "Jan" (x-axis point) will have 2 Y-axis pointsThe problem :Is there anyway to force flex to show tooltip on both series simultaneously?
I'd like to be able to tell my ADG to set a specific row to be highlighted and update the adg rendering to match such new value. Note: highlight != selected. I thought perhaps setting highlightUID would do the trick, but I can't seem to get the ADG rendering to update.
I am experimenting with e4x. I could programmatically add an attribute to an Xml by doing something like this :
[Code]...
now i have added a name attribute to it programmatically because even though the xml had no attribute called name, after the statement above, it automatically has one now. My difficulty now is how do i , as well, remove the name attribute i have inserted programmatically again?
I would like to programatically fire an event on a spark checkbox. I have a tab bar which has tabs enabled according to various checkboxes. I am loading data into these tabs. Sometimes tabs 1 and 2 will be enabled. Other times tabs 2 and 3. Other times tab 4 by itself (and all the other combinations). I have tried to enable the VBox (in action script) which is in my view stack but it seems to freeze the application. The VBox enables correctly upon user input on the check box. If I set the checkbox to be selected it does not fire the event and so does not enable the tab.
Is it possible to manually fire an event in Flex. I have tried to see if I can take the checkbox and get the event and fire it. Unfortunately I can only see addEventListener, hasEventLister and removeEventListener. There is no way of getting the events that are already on the checkbox
