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.
View 2 RepliesI have a number of thumbnail images (8K ish in length), stored in a sqlite database, encoded as base64 strings.
I would like to retrieve these images and present them into a datagrid (along with some other information from the DB)
The retrieval of information from the database works, but I cannot quite "see" how to connect the decoded result from the database to the datagrid, to display the images.
Below is some code, where I show (to simplify things) a simply DGrid and want to use the dataprovider to point to the select from the DB[code]...
I have a Datagrid that already gets its data from a data provider, there is a column in the grid called priority. What i want to do is if the column priority contains the value high then in an empty column in the datagrid i want to insert and image , the image being inserted depending on the value of the column priority.
View 1 RepliesI've got content coming into my application using a query and an ArrayCollection. I know how to display the content into a DataGrid by using the dataProvider propriety, but I'd like to use TextInput components and drop the DataGrid altogether.
I'm still having a problem all that displays is [object,object]
Here is a bit of my code.

private var acCon:ArrayCollection;

How to load images in as3:Load them all at once, for example like this (pseudo as3 code):
for each (var url:String in images){
loader.load(url);
}
[code].....
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 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:
/Bildvisare-debug/
Bildvisare.html
Bildvisare.swf
/Images/
[Code]....
The problem is that the images never show up, I only get the icon for a missing image.
Edit to add: I've tried this both with and without the use-network flag set to false when compiling.
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'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 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?

View 1 RepliesI am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

import mx.containers.HBox;

How to turn Flex MXML DataGrid into something like Horisontal DataGrid? (may be some how with Flash builder 4?)
Keeping all stuff DataGrid has like eating data from data provider sortind dragging - droping items etc
I have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

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.
View 2 RepliesI am trying to load multiple images into a scene and then cycle through the images one at a time.So, here are the essentials what I've put together in AS3:First I set up a counter and a Loader

Then, after loading a list of images from an XML file, I call a function that I called "createImages". This function then takes the list of images and creates a bunch of loaders:

So far, so good! I now have a bunch of loaders each with a different name "img1","img2","img3" etc.

I am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:

I am using actionscript 3. I can load an image in a class but how do Iload a number of images eg 4 images that animate.?These 4 images are a walking sequnce of a character. I am unclear after googling an loading multi images in as3( just love google).
Loading a single image I load this into a loader Once loaded I load the image into a bitmap and add to a sprite I then add the spite to the stage Q)Now for 4 related images I load 4 loader or 4 sprites or 4 bitmaps or do every thing 4 times?I want to do collisions eventually and I need bitmaps but bitmaps seem useless to use other than collisions.Googling for answers isnt helping me clarify this!

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.
View 2 RepliesI have a rotaing menu that loads in images from an xml file, I would also like it to load in text info from the same xml file to the left side of the images that load in. In my main .fla have created a movieclip and called it 'textInfo' and inside that I have two dynamic text fields called 'headerText' and 'bodyText' where I want to load the text in. this is what I am using to loading in the text in my actionscript, is this correct?

I had the code to load my XML into a Flash Datagrid Component, but I played with it and lost the original working code! Does any one have a way to load:
<?xml version="1.0" encoding="utf-8"?>
<accounts>
<Account>[code].........
It is just a rough, local, XML file, but has the same tags as my main one. I want to have columns of User, Xp, and Rank. I found a whole bunch of tutorials that load an Attribute of a node, but nothing about a plain node. Also, it would be awesome if you could also explain how to select a row and go to a certain frame.
All I want to do is load an .xml file in to a datagrid component and it just won't work.
I don' even get eny errors
I'm able to send and save variables to an .xml file, just not view it in the data grid.
I will post my As3 code below

View 5 Replieshow can i load a image into a datagrid
View 3 RepliesI have successfully dynamically loaded Jpegs into my flash document(using PHP), but then I have another small problem.When I dynamically load the image (example: image_icon_bluesky.jpg) I then need to tell the MC that is holding the loaded image that it needs to do this...
on (release) {
_root.image_bluesky.alpha = 100;
}
SO basically every time a new image is loaded in my sort of "loop" script. I need to tell the image that it needs to put specific code onto the MC using specific "image" details for that specific image.
I hope this is clear. Basically what I'm trying to do.On my flash stage I already have MC's that have their alpha properties set to "0". Lets say there are 3 images. One MC is called Blue, other is called Red and the last one is called Yellow.Now using AS + PHP I have dynamically loaded 3 Jpeg's .

and so on for each image....I have tried to explain this as well as I possibly can. I just wanna know if this is possible or if there is a simple way of doing it
I also have two different simple XML files, each would only be a single column of data, lets say they're called file1.xml & file2.xml I have 2 buttons, and I want to be able to click button 1 and load the data from file1.xml into the datagrid and have its column of data displayed, same for button 2 and file2.xml.
