Flex :: Use Single Collection Object To Two Different UI Components?
Aug 22, 2011
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.
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.
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'm using zend_amf and flex. My problem is i have to populate my advance datagrid using array collection. this array collection have a children.[code]...
LinkeSetFx has its own CollectionEvent, but I don't know how to map the LinkedSetFx event to mx.events.collectionEvent(I want use it in ComboBox). LinkedSetFx is in AS3Commons-collection framework.Here is the url, choose the as3commons-collections-1.0.0.zip, you'll find LinkedSetFx in srcorgas3commonscollectionsfx
When I get a collection back from the service tier, I create an ArrayCollection and apply a sort. When I add an item to the collection later on, the sort is still in place? It seems to be the case. I thought I was only sorting it once, not applying a sort that will stick??Here is the method for adding an item:
private function onAddNewClick():void { var fileTemplate:FileTemplateDetailDTO = new FileTemplateDetailDTO();
I am created a dynamically adding a VBox, that contains two images. Into a Custom Component that is derived from UIComponent. The problem is the Vbox that contains the two image is only a really tiny size. I would like the VBox stretch to the size of the two images. This is how I am creating the Vbox....
Is it bad practice/design to nest components inside components using Flex 4? Should I simply be creating components and inserting them into my main application as below, or doesn't it matter?
In my flex application im using two datagridfirst datgrid is for items collectionssecond is for bank details.if i click one row in first datagrid (which has the items collections)...a unique code is taken from the grid(which is primary key).then, i have to select two or more banks using itemrenderer checkboxes in second datagrid(which has the bank details)ow, have to bind the bank details(one or more banks) with that one primary key in first datagrid. to an single array collection... and have to show it in another new datagrid(thirdone)
I have an application that takes some database info and shoves it into a datagrid, or chart. I've come across this error of having a single row and trying to use it in an array so I can use it in my app. Its come to my attention that its a pretty common problem that people face, but I don't seem to be able to get around it no matter what a try. My actionscript has a fucntion that trots of to the database via ASP, and returns the data in the event - as below (obv i've removed some stuff - load of calls are made to the mssqlQuery function - only the one I have trauma with is below)
ActionScript Code: var clip:Sprite = new Sprite(); clip.name = "clip" addChild(clip); cleanup(clip) function cleanup(mc):void { mc.parent.removeChild(mc); mc = null trace(clip) // clip is removed from stage but traces as [object Sprite]. It still exists! }
How would I pass a MovieClip/Sprite/TextField through this function and remove it entirely?
I'm working on a project which allowing end users to embed a flash in their own HTML pages while we offer different ways so user could choose one that works for their circumstances, for example, most blogs doesn't welcome users to inject JavaScript on their pages, therefore SWFObject wouldn't be possible, we offered two other ways: IFrame and the oldie but goodie Object/Embed pair. Just like old Youtube embedding code:
Does anyone know an Actionscript equivalent of the javascript getElementsByClassName.
What I would like to do is add a custom 'stylename' to various components which I can then use to get a collection of these objects and therefore process their visibility property.
The idea is I want to hide various components based on what roles a logged in user has - I just want to make this flexible by adding an array of rolenames to a custom property or use the stylename property on a Canvas or Panel etc.
In my attached file first user drag dot symbol into the block targets and then user drag the arrow in the same targets.now i want to set both are in single target.( see the screen shot of target.png file )
I have a collection in Flex and I have sorted it by a date field, so the latest elements appear first in my view.
In order to do this I have applied a sort field like so:
var articleSort:Sort = new Sort(); articleSort.fields = [ new SortField('published', false, true), new SortField('id', true, true)]; articles.sort = articleSort; articles.refresh();
Now I want to be able to use a cursor to findFirst() in that collection based on the id. However in order to do that I have to also pass through the published date in the findFirst() method. This is a real pain as I don't have the published date at that time, (or it's expensive to get).
As you can see I am having to get it from the modelLocator in my application, and basically look up the item...
Ideally I would like to pass a wildcard though for the date in the FindFirst() function, as the id is the only thing I care about when searching. However it seems it Flex I can't do that.
The other option that occurred to me is to resort the collection before searching, but that would cause my view to re-render (as it's bound to the collection) on the collections refresh event. Plus it seems rather silly to have to resort in order to search.
For example in Java you can do:List<Person> where Person is the object type.In AS3/FlexArrayCollection which takes any object type. Is there any way to create a list/collection of declared objects in AS3/Flex (or is it impossible due to weakly typed language)?
I am working on simple flash game in which there r 8 small circles out side of one big circle. i want to drag this 8 small circle one by one to the big circle.Basically 1 plate with their food items.Draging their food items to he plate. i hope this would give you a better idea.I have goggled it the same thing but could not get what i want,
Any good argument as to why I shouldn't use a Dictionary over an Object every single time? I can't think of any case an Object can do the job a Dictionary can't, and it doesn't seem as the Dictionary creates that much more overhead.
I have an array, crewPositionsAC that contains a list of position abreviatations - EP, PR, DR, WR, and so on. These positions are read in through an XML file each time my flex application loads. Also being populated from an XML is a project. Within a project, there are positions (a student assigned to a type of position listed within crewPositionsAC). These positions are not necessarily in the correct hierarchy order dictated by crewPositionsAC. I have all the positions within an ArrayCollection (positionsAC) with the following structure:
Then, the user can click a button to add another position. When the "Add Crew Member" button is pressed, the user is presented with a list of possible positions to add. Currently, I simply add another array to positionsAC. This results in the recently added crew member to placed on the bottom of the list. I need to take positionsAC and reorder it based on it's [2] item (role) based on the hierarchy defined in the crewPositionsAC. crewPositionsAC has the following structure:
crewPositionsAC: [0] = EP [1] = PR [2] = DR [3] = WR
* continue until all possible position types are listed
Im trying to populate a tree control with an external xml file brought in via arraycollection but i need to group the xml data to display in the tree Okay my external xml file is called parts.xml and it looks like this:
[Code]...
additionally what i intend is for the user to have huge tree of parts and they select a node at the partnumber level and drag an drop it on to a datagrid where all the other tags of the part gets displayed.
Ive tried and tried many things without any luck. even now im thinking maybe if i looped through the array-collection and created a new array just for the tree to get it to display the way i need it, then when the user dragged and drop a part onto the grid i would have code that would look for that part number in the original arraycollection and add it to a new array just for the datagrid... i still dont know how i would create that new array for the tree!! cause the xml data is grouped by partgroup and then grouped again by parttype before you get the individual part numbers
I have an array collection that I would like to limit to say 100 items. I tried setting up a filter function where the return was:return (myAC.getItemIndex(item) > 100);but the value was always -1. For whatever reason it couldn't find the item, even though the item is definitely there.I'm able to do this with a while loop:while(myAC.length > 100) myAC.removeItemAt(100);
