i'm a very new user to flex (never use flex, nor flashbuilder, nor action script before), but i want to learn this langage because of the beautiful RIA and chart it can do.I watched the video on adobe : 1 hour to build your first program but i'm stuck :
On the video it says that we have to provide a PHP class for accessing data and i used the example that flash builder gave (with zend framework and mysqli). I never used those ones and it makes a lot to learn if i count zen + mysqli.My question is : can i use a PHP class like this one ? What does flash builder except in return ? i hear that was automatic.example it may be wrong, i'm not very familiar with classes when acessing to database :
<?php
class DBConnection {
protected $server = "localhost";[code]..........
I have been pulling my hair out over the past hour into why my code will not work and i really don't see why not but it clearly isn't so i require help on two things:
#1 Flash trace call will not show data i ask for.
My Script
Code: var xmlLoader:URLLoader = new URLLoader(); var xmlData:XML = new XML(); xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
[code]....
#2 How do i add this data (once it works!) to a dynamic text box called tTOTD?
How do I provide values from the dataprovider (which is an array of objects) to these individual numeric steppers. dataField cannot be mentioned in the NumericStepper tag it seems.
in Flex if i have a loader class (i.e., XMLLoader) and a document class (document.as) and in document.as I'm instantiating XMLLoadervar ldr:XMLLoader = new XMLLoader(url);... and on the document.as class I have a text box, which I would like updated with the progress from that XMLLoader is making by using URLLoaders progress event, continously. Meaning, the box would show the load in bytes that it is recievingI'm not sure how to constantly push data out of an event and add it to another class. For example:
myLstnr.addEventListener(ProgressEvent.PROGRESS, getProgress); private function getProgress():void {
I'd like to give someone else the FLA to recompile SWF's, but the libraries I'm using are spread out in many places (Tween libraries, custom libraries, etc), and would be somewhat arduous to package cleanly to include with the FLA. compile the imported libraries into the FLA somehow?
Im a complete beginner in Flex programming. I have an application with a main .mxml file, and a certain class Foo that I call from the .mxml. In Foo, I make a URLRequest and listen for the Complete event. Then I found myself with the returned data in a Foo function, but I have no idea how to communicate it to the .mxml part of the application ! I looked into ArrayCollections but I can't seem to understand how they work. Isn't there a way to modify, from inside the class, a variable with a global scope ?
It is fully finished and before the site was finished we discussed charges for updates. They just requested the source files. We had never discussed this, and I do not want to give away my source files and all of my code. What is standard? Am I wrong to have them go through me for updates since this is what was discussed?
I am developing with Flex + java + hibernate in one project. I am trying to add one more advanceddatagridcolumn in flex AdavanedDataGrid control. Actually it work very well but only except I added columns data. I have no idea what should I do to make it out I am telling work flow. At first call select method in DeliveryService.class through the RemoteObject and then call DeliveryMgr.class for call business work. After get return list type return value it pass to presentation class to setting all of the selected return value. I can print trace log what I added columns data in DeliveryPt.class but it cannot return to flex area.Strange thing is I can check out value of what I want to show data in DeliveryPt.class but it does not show up in AdvanedDataGridColumn of Flex.
We can obviously provide embed code to users such as.[code]which is what every (ok, so not every, but the vast majority) video sharing site does (YouTube, Break, Vimeo etc).However, somebody's pointed out that we could also provide a JavaScript embed link as follows:[code]What's the disadvantage of the JS embed option? The advantage is obvious, it's a nicer URL for the user, less characters to place in their site. I'm worried about security here, as somebody who doesn't know JavaScript; is this an inherently insecure way of doing things? And if the JavaScript URL is fine, how come none of the well-known sites do it?
What are the best practices for providing dynamic content within a flash site? I am trying to get my head around the idea and I am not sure how to think about this. Are there sites that use a graphic frontend for updating flash content? If so, what is the common way of doing this? XML? PHP+XML+SQL? etc. I am relatively new to all of this but I have been messing with Flash and XML. I can update stuff on my site by just modifying the XML but I want to go a step further now and create a frontend on the web where people could do this.
I created a movieclip with a star. Then, I creates a document class and I named it as Main.as.
In that document class I wrote: package { import flash.display.*; public class Main extends MovieClip
[Code]....
Iīm not posting here all the code, but you can easily see that Iīm using x_origin and y_origin variables to keep the original position of the movie clip. I will use them to move the star back to the original position.
The problem is that instead of being 20 and 30 respectively, tracing them I see that they are both ZERO. So when I drop the star, instead of going to x=20,y=30 it moves back to x=0 and y=0. Iīve to get the star position relative to stage, but I canīt find anyway!
When I first downloaded Flash CS3 Professional, I was able to enter an exceedingly useful debug mode by compiling using ctrl+shift+enter instead of ctrl+enter. I could toggle break points, step in, step over and view values stored in variables at a whim.
I must have accidentally toggled some option somewhere, because this interface no longer shows up. Instead, the only extra interface I get is the output menu with the following text "Attemping to launch and connect to Player using URL <file path> [SWF] <file path> - 71984 bytes after decompression" and while the swf does halt if the as3 code reaches a break point, it doesn't tell me which break point nor give me any options to progress the flow (not even through the pull down menu I have to utilize in order to end the so called debug session).
In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?
I have to populate an Advanced Data Grid which have the following fields: Continent->State->Society-->Actual Value-->Estimate Value I want to simulate a financial market so i have to change some of the values by asynchronous request from an HTTPService; If necessary i'll post the .as file, but it is generated automatically by Flex Builder.
Here's the code of the client side Flex/Air application:
I want to separate the data from the PHP call to Different CollectionArrays So that I can use the data for a bar-graph;
I created a static version of the bar-graph and separated the Collection array manually I don't want this done manually I need to do it dynamically. So what I am trying to understand is where to put the event-listener how to add to a collectionArray then once the collection array(s) are built. use that information to build the bar graphs...
I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
I have been goggling a lot to find anything with link-based data visualization in Flex 4. something like below screen shoot (made using Ravis). Where user can drag these nodes, without removing the links and on double click of any node we can set some properties for that particular node. I found this Ravis (Birdeye), but not much of examples and support is available for that.
I have an xml file (externally saved) that is similar to the following:
[root] [main] [title]...[/title]
[Code]....
What I like to do is to get what's in [title] tag using HTTPservice, import it into Flex, and save it as array objects, and do the same thing for [content]. This way I can later refer the array object saying title[0] or content[2].
I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).
I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)
[URL]
The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.
If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.
On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG
My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.
I have a radio button group within a data grid, whenever I attempt to change the selected radio button the web page crashes. Below is how I put together the radio button in the data grid.
My data grid is displaying stale data, rather than the real time data available in it's data provider (array collection). I've tried refeshing the data in the collection, but that has no effect. Below is my code, does anyone see what could be the problem?
If user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.
This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.
