Flex :: Communicating Between Itemrenderes In A Single Row
Mar 21, 2010
I have a datagrid with an XML object as dataprovider. There are 2 columns in the datagrid which have comboboxes as their itemrenderers. The rendereriseditor property is also marked true. These itemrenderers are defined in their own mxml files. What i want is if the user selects a particular item in the combobox, say NA, then the value of the other combobox should also become NA.
Firstly sorry for the really lengthy question. I am trying to implement an Org.Chart using spark DataGrid. The data for the Org.Chart does not change and hence I am hard coding the values. I had to implement this Org.Chart as I need to have floating Nodes and also the connecting lines should be drawn a bit different when compared to using an external component. Please find the following image of which Im trying to achieve: Here is the idea:
Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
Over the past few weeks I have been building a prototype application using a Flex front end connected to a J2EE backend using blazeDS. The prototype is an experiment to learn flex and see what its suitability is for a complex trading application requiring a large number of dynamic updates (i.e > 20 a second) via a pub sub type model. During some lightweight performance tests it's become apparent that I need to use multiple threads to ensure the UI remains stable when receiving a large number of updates from the server. All was going well until I discovered that flex has a single threaded programming model!
From a quick Google it looks as though there are numerous hacks to implement thread like behavior. I am sure many people must have been faced with a similar problem. Can people let me know: Are there any good threading libs that are well maintained etc Do other RIA technologies such as silverlight have the same problems. Why did abobe implement a single thread model? Are there any other tricks I can use to ensure my UI is stable.
I was modifying the layout of a Flex application in Flex Builder. What I didn't realize was that the changes I made, were made for a particular state. There are around 6-7 states in my application. Now, I need those changes to be made to all of those states. How do I do it? As of now there are multiple lines like this in one state :
I have two xml files, defect. xml and employee.xml. But the files havea common field but with different names in each file. I want both the files to be merged in to a single array collection.
The structure of my defect.xml file is:
<defectList> <defect> <revId>123</revId>
[Code]....
Now, if I give datafield as "employeeId" in the datagrid with defectList as dataprovider, I get the employee id of the corresponding Employee Name.
Flex data grid has 1 default row created. When user clicks on the second row, a new row needs to be created and made editable.
Here is what works already - user tabs over the columns and when the user tabs while in the last column, a new row is created with default values.
Here is also what already works - user click a button outside the grid, which adds a new row.
(itemEditBegin and itemEditEnd have been implemented)
Here is what does NOT work: When I "single click" on the second row (no data yet - row is null), how do I detect that the currently clicked row is the second row and make it editable? Can I figure out the rowIndex from MouseEvent and use this to add a new row?
I want to select information in a single cell from my DataGrid in Flex 3.
Specifically, I'm displaying three phone numbers per line and the user needs to be able to select one of those numbers, from any row, but not the whole row.
While similar to this, I am displaying the DataGrid to the user. The answer for that question was to manipulate the dataProvider, how can I know what cell I've selected in order to do that?
Can we use 2 timer events in a single application. I'm trying to use 2 timer events in a single application but the 2nd timer event is not working.... any one have an idea??? how to use 2 timer events in a single application.
I'm working with video in Flex. I'd like to be able to pause the video at a certain point and copy the displayed frame as an image, and save it to a database. how I might copy a single frame from a paused video?
I have an application in flash, I build in ActionScript 3.0 Flash IDE, my application loads some external swfs which mentioned via XML file. Its working fine at the moment. But I need to compile all these external SWFs and xml file into single exe file. How can I compile like this. or how can I code like this?
EDIT: 1 from here : [URL]
You can see an example, the application is build in .net and it import pdf and publish it as flash projector or web based(swf). How is it compiling all the external SWF files.
I want to use single collection object to two different UI components. 1. Datagrid and 2nd is chart component. I dont want to change anything inside the arraycollection object but I want to use it at the same time with two different component with minor changes. I know we can use filter function some how but not sure how to apply filter to arraycollection object so that one component (datagrid) can use the original arraycollection object and second component (chart) used the modified one.
How can I populate multiple datagrids in flex with a single datasource that is filtered differently for each datagrid. I'm assigning the event.result from my remote object call to three different array collections, each with its own filter function. When I assign and refresh the filter functions, they each affect all array collections. So, the results of the last array collection refresh end up in all three datagrids.
I'm using CF to retrieve values from a database that are then being stored in a datagrid in Flex. I then want to selectively take the value from one cell of the datagrid and store it as a string variable. I've searched around, but I haven't been able to come about a solution. The users will not be interacting at all with the datagrid as it will be hidden to them.
I have data model (dataProvider as ArrayCollection) i want to display in few views , each view should show filtered data. As you probably know, filterFunction is property of ArrayCollection,so I can't use this solution (unless creating new instance of ArrayCollection for each view on top original and impementing filterFunction).
I have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.
I have a flat data array that comes form a remoteobject, I want to group whatever is to be grouped, but leave single items (the ones with no common data with anything else) alone and without grouping, it's annoying to open each node only to find there's just one item inside, so there was no need to put it inside that group anyway. I can't find any reference and I don't know if getting the hierarchicaldata out of the groupingcollection and then iterate thru it would be any good, sounds like a lot of duplicate work.
Here is my question:I have a hybrid chart that uses bars and linesI want to add to the right vertical axis a horizontal line that represents a break even
I have created a custom component that I am using, more conveniently, as a SkinnablePopUpContainer and I want to use the same function that calls and receives data from it for several Buttons in the UI. What is the best way to achieve this without having to create a new function for each button?
I want to use a Spark ComboBox with numerous MX Components but the Spark ComboBox does not look the same as the MX Components. Is there a skin I can use to Skin Spark components like MX components?
i am beginner dont know how do display all country time into a single page using action script 3 in flex . do u know any example time code refer me . i will try that code .
How can we customize the background and font color of a single instance of a tooltip for one component? (Without changing all tooltips in the application.)
This is needed for the HALO component set (4.1 SDK), not Spark (css methods preferred).
i need to connect to two different domains from a single flex application. the problem is the domain other than the current hosted domain is unable to login. letz say i hosted the application at LOCAL server. im able to login to the local server . From the existing application i need a login to the MAIN server too. The problem comes up here. flash security is not allowing login to MAIN server. in crossdomain we allow-access-from MAIN server. but i want access to the MAIN server from LOCAL server. is ther nything i need to put extra in [URL]?
i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error.
TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection.
this error occurs as the line of code: myList= e.result.list.name;
Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider?
I have a maven project that produces many artifacts. Of course it is kind of against maven best practice (one pom one artifact), but it is Adobe Flex project that produces many *swf modules and it is really makes no sence to create a separate project for each module.
For me it would be very convinient to handle all swf modules as a single zip archive eg. zip archive would be my artifact.
So I am looking for the way to pack and unpack my zip artifact with maven.
I want to show the second line series underneath the first one, however with this code they are appearing sequentially. Not sure how to make sure they are overlayed! I followed some code I saw for combining charts.. not sure what to do.
I have created a simple mxml file with code as follows: <s:application..........> <s:BorderContainer> <s:SkinnableContainer id="firstRow"/> <s:SkinnableContainer id="secondRow"/> <s:SkinnableContainer id="thirdRow"/> </s:BorderContainer> </s:application>
Now I want to apply different font size, font color and font type and background color on each row i.e each of the three skinnableContainers.Currently I have defined 3 different skin classes for each of row but I think this is a bad programing. I should create a single skin class for outermost container i.e BorderContainer and any how provide different fonts and background color to all the 3 child containers through that skin class. So, is it possible that I can create single skin class that can provide different decorations to each of the child container.
