I want to know if anyone can point me in the right direction for individually loading images (I think thats what is happening) in Flex 4.I saw this site and I like the way each individual picture gets loaded when a new category is opened and thought it would be very useful in our next project.
View 1 RepliesI've gotten as far as getting a listbox with a list of articles to display the articles in a dynamic text box, only i can only get it to work if i use one huge external text file that contains all the articles. what i want is to have each item on the list open up its own external text file, i.e. for each item on the list, there exists a separate text file. I'm about ready to put my fist through the monitor, and that would suck because this is a really nice monitor

But, I need a small twist. A transition image i.e. loading image should be displayed while the the image is being loaded.
I have a map of the UK with around 30 markers on when these are clicked I need the box to appear as shown in my attachment. These all need individual data and a unique link. Could I load the clip from the library and then populate the fields using xml, could this also work for the link?

View 5 Repliesbuild an image gallery on a site i'm building.The way I have built the site use sactionscript to pull the each different page through as an individual swf file. see: http:[url]....The page im putting the image gallery on is 'Virtual Tour'.When I test this specific page in flash it works fine, however when I view the master flash file and click 'Virtual Tour' then it doesnt pull the images through. Im not sure why this is, as if you view the swf directly then you can see the images do work: http:[url]....
View 4 RepliesI am trying to create a picture gallery.. I can arrange the thumbs in the screen and when I click to one of them, it shows the bigger picture. But the problem is, I want the thumb to do something when the mouse is over it.
Code:

import com.greensock.easing.Cubic;
import com.greensock.easing.EaseLookup;
import com.greensock.TweenMax;

When I use that tweenmax.to(this.....) part, all the thumbs act like one. I tried to change this to thumbs but I didn't work. How to convert all the thumbs to an individual image?
I'm dynamically loading images from a JSON feed into individual movie clips and then adding the clips to the stage(both by addChild)--basically creating thumb tiles. I've added a click handler to do something when the MC is clicked. WHAT'S MY PROBLEM: The problem I have is that the MC is clickable, but the content is not. For instance, the clip has a white box in it, and the loaded image is made slightly smaller and centered to give a white border around the pic. An empty clip loaded to the stage works fine, and the white border around the image is clickable, but the image is not.
View 1 RepliesHow much of an impact does import flash.display.* over individual loading make? I'm using FlashDevlop so its auto created but the list is getting huge. Is there a significant savings by not adding all of them. Or better question if its imported but not used will it be added at compile time?
View 1 RepliesI am currently doing a project which involves quite a large swf file at the end. I was wondering if anyone knows a way that i can easily make it so that at the begging, when first loading up the flash, it just loads the menu and a couple of other frames, but when i go onto play the game, it will load each level just before you play it, so that the player doesnt get bored from waiting right at the begging for a while when they can wait 5 seconds before each level.
Im pretty sure ive seen this done before but im not sure whether it is preparing it in that time, or downloading it. I want it so that there will be a 10-20 second wait for the game to load up, then you go to the menu, press play, loads the next frame, or certain number of frames, you play that level, then it keeps on doing this for all the levels.
I have just implemented a dropdownlist of checkboxes taken from this ComboCheck example but made it extend DropDownList instead of ComboBox to provide better functionality that I required. I am attempting to create a DropDownList where some items are bold and non-checkboxes (or can be checkboxes) and others are not.
I have not been able to find anything online about doing this yet and have been trying to figure it out. I am currently using an ArrayCollection as a dataProvider but I think this could possibly be my issue and I should be trying to setup the labels in flex not AS3.[code]...
If I have a button named:
<mx:Button id="backButton">
and another named:<mx:Button id="cancelButton"
How can I style each button seperatly?
Can I give each button a style, then set the style in CSS... E.g.
Button #style { backgroundColor: red;}
I have figured out a way to change the style of tabs at run time with following logic:
var cssStyle:CSSStyleDeclaration = StyleManager.getStyleDeclaration(".MyTabs");
cssStyle.setStyle("borderColor", "red");
But here ".MyTabs" class is applicable to all the tabs between first and last tab. As per getStyleDeclaration javadoc, it only accepts "class selector" and "type selector" not the id selector.
How can I change the individual tab style at run time?
How can I disable a single button in a buttonbar in Flex?
View 2 RepliesI am trying to load an image in Flex (AS3) which already exists:

I have Flex 4 DataGrid, what I would like to do is when an cell has been edited, I would then like to walk through the values of that column and preform math on the values, e.g., I want to total up certain values.
1) How do I reference individual values of a specific column so that I may set them.
2) How do I then set those values or should I create a new column array and pop it in place of that column.
Having read about Container creationPolicy (thanks all the references in StackOverflow)I have a TabNavigator and AS code in the initial Tab needs to reference components of second tab (a Canvas with multiple children).But the components of the second tab are null until that Tab is rendered.
According to the documentation as I read it, I should be able to set creationPolicy on the second tab/Canvas to "all"; the TabNavigator will instantiate all its top-level children, even with its multi-view creationPolicy="auto"; and I was hoping that when creating the child Tab/Canvas, that the creationPolicy="all" of that single-view Container would be honored.
But it appears that this is not the case; if the TabNavigator has creationPolicy="all" then the second Tab is populated (but so are the third, fourth, ...); but with "auto" the second Tab is created, but not populated, even though its creationPolicy="all".Is there a way to get just selected Tabs to pre-instantiate?
I need to write and test xmlStuff.as. I would like to test it on its own without launching the entire application (launched with index.mxml).
Project
Folder: src
Package: Default Package
- index.mxml[c
If I was using java what I would do is I would create a new package: [url].....
And I would put this code in it:
public class xmlStuffTester {
public static void main(String [] args){
XmlStuff xs = new XmlStuff();[code]...
(Alternatly I would write a unit test if I knew exactly what the xml output should be. I don't know that yet so I prefer the above approach.)Question: What is the standard way to do this in Flex builder?
I need to be able to save and load images into an SQLite database using Flex 4.5 for a mobile application. The use case is this:
Inside the view there is a spark Image object with a URL as a source
When user clicks button, the Image is saved to an SQLite db inside a BLOB field.
In a separate Image, the source is set to the ByteArray stored in the db.
The biggest question so far is this: where do I get the ByteArray for a loaded Image? I've tried debugging and inspecting Image, BitmapImage, and BitMapData but there's no sign of the byte array.... perhaps it's inside the ContentLoader? But that's null unless I enable caching.
I've done some research and there are no complete examples for how to handle this. I've written a simple View that anyone can copy and paste into a new project. It will compile without errors and can be used for testing. I will update this code as I get the answers I need so that anyone can have a fully working example of this workflow.The only caveat: I used a synchronous connection to the DB to avoid complicating the code with event handlers, I wanted to keep it as simple as possible.I will only mark this question as answered once it is fully functioning both ways.
UPDATE SEPT. 09 2011: The code below is now fully functioning in both directions (save and load). Here are some of the things I've learned: It turns out that the ByteArray of a spark Image can be found inside the LoaderInfo of the image itself. Like this:
image.loaderInfo.bytes
However, trying to set this ByteArray as the source of another image ( image2.source = image1.loaderInfo.bytes) results in this security error: Error #3226: Cannot import a SWF file when LoaderContext.allowCodeImport is false.Which is too bad because it would save so much time and processing power.the workaround is to encode the ByteArray using either a JPEGEncoder or a PNGEncoder. I used the JPEGEncoder which produces much smaller files. Here's how:
var encoder:JPEGEncoder = new JPEGEncoder(75);
var imageByteArray:ByteArray = encoder.encode(imageToSave.bitmapData);
Now the problem is saving these bytes to the DB. Saving them as they are now will not work once we read them out, I'm not sure why. So the solution is to encode them into a base64 string like this:
var baseEncoder:Base64Encoder = new Base64Encoder();
baseEncoder.encodeBytes(imageByteArray);
var encodedBytes:String = baseEncoder.toString();
So now just save that string into the BLOB field and later read it out. However, you have to decode it from a base64 string to a ByteArray like this:
var encodedBytes:String = result.data[0].imagedata;
var baseDecoder:Base64Decoder = new Base64Decoder();
baseDecoder.decode(encodedBytes);
var byteArray:ByteArray = baseDecoder.toByteArray();
Now assign the bytearray as the source of your image and you're done. Simple right?if you find any optimizations or alternative ways to do this.I will respond and keep this code updated if need be.
I am creating a chart using mxml. The mxml tags only create a chart with a horizontal axis and vertical axis. My result event handler has actionscript code that loops through the xml result set and creates all the series (line series and stacked bar). This part of the code works fine. Now I need to use the functionfill function to set individual colors to each series. All the examples I have found call the functionfill from within an MXML tag, like so:

I have a custom circle component in my application, which is divided into 3 sectors as of now.Can we uniquely identify each segments of this circle? I want to drag and drop text or images from another container to this circle component. But I want to place different images in the different sectors. Is it possible to distinguish the individual sectors of the circle component?[code]Actually I want the circle to be divided into 6 sectors, but for now just divided it into 3 sectors. But is it possible to uniqulely identify the individual sectors of the circle so that I can drag different images or texts into those particular sectors?
View 1 RepliesIs it possible to control the properties of 'advancedgridcolumns' in 'advanceddatagrid' mxml tag. For e.g. suppose the grid data provider has 3 different fields. Out of these 3 fields, one field is 'to_be_decided'. This field should not be displayed initially. Only the remaining 2 columns should be displayed (visible true) and the third column (one with data field as 'to_be_decided', visible flag will be false here ) should be hidden. It will be visible when some event like a button click or something is fired.
We can do this in action script coding by accessing individual columns of grid and taking appropriate actions. But will it be possible to do so in mxml? Is there some default property in grid that can be used here ?In mxml I can not access them individually in the grid (under tag) and hence I can not set the visible attributes individually for each of them. To add them one by one in 'columns' tags I would be required to know the data field in array collection and that I dont know. Only data field known is 'to_be_decided', rest two fields will vary time to time. Therefore even if I addd this one gridcolumn in 'columns' tag what about the other two?
Something like this :
<mx:columns>
<mx:AdvancedDataGridColumns dataField='to_be_decided' visible=false>
<!-- How to add other 2 columns here ? -->
</mx:columns>
I have a Flex DataGrid where one individual cell needs to be rendered in a different way from others. Specifically, for one row of the grid, one of its cells should be hidden.
The DataGridColumn is set out like this in my .mxml file:

but that doesn't work - in fact it messes up the display in a rather entertaining fashion (one of the other cells in the row gets an extra checkbox.. I suspect it may be possible by using a custom ItemRenderer class but that seems like a lot of code overhead for a fairly simple case.
how can I load in flex spark Image control and wait for complete loading? MX:image have method load() and listen COMPLETE event this is not in spark Image...is there only source?? or how can i listen when image is complete loading??
View 1 RepliesI have an arbitrary number of files that I need to load in an AIR app.I want to iterate through an array of File object and create and launch Loaders for each one's File.url.When they are done (event COMPLETED or IOErrorEvent.IO_ERROR), I want to stuff their data somewhere. If they fail, I want to make an exception report. I cannot find any way to reference the File object from the event listener (certainly not the IO_ERROR)The best way would be to create individual event handlers for each Launcher that had the File information "hard-coded" into it. At the very least, I could use the function itself as an index to a Dictionary:
foo(fileToLoad : File) : void
{
var theCompletedHandler : Function =
{
[code]....
Can I use event.currentTaget and use the Loader instance as an index? Will that have any weird dependencies ?
