I am adding data inside a VGroup dynamically using Action Script. Each data is an instance of a custom component. So when the number of item is more, It take time to load, which look bad.
Is there any way, we can load data to it, asynchronously or is there any way, so that more data can be added inside a scroller only when the scroll bar reaches to the end ( as it happens in Android or IPhone).?
I would like to position relatively a scroller in my application like below.When I scale the image, I resize the scroller...
<s:Scroller width="50%" height="50%" >
<s:Group>
<mx:Image

I have a data grid who's data provider is set to an XML object.
Code:
<mx:DataGrid id="streamMonitorGrid" dataProvider="{_data.stream}" height="100%" width="100%">

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.)

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 am currently working on an Adobe AIR application that shows the user some graphical data. As this data is more in height to fit the screen height, I've placed it inside a scroller.
Now I want to take a print of this visual data, mostly some charts and lists but I only see a single page containing only the part of the screen that is currently visible to the user. I want to have the entire content inside the scroller to appear on the page.
I have a datagrid component and each time I update it, The scroller goes to the top, and doesn't stay in the same place it was before the update.
View 2 Repliesi have some code that moves a movieclip container(mC) left to right in an "infinite" fashion. The container is populated with image via xml and i have two categories with different xml files for each.
When i initially load the swf, everything works as though it should, the images scroll left to right infinitely. When i switch categories (go to frame 2, removeChild(mC), return to frame 1 with variable set to other category), loading in a different xml, the scroller no longer works. it registers that i want it to move from side to side, but it seems to be governed by something else. If i try to switch back to the first category again, the same thing occurs where the movement is broken.
Does it have something to do with garbage collection not occuring to clear out the values of mC and its contents?

View 1 RepliesI have a main.mxml application that lays out my application, it contains a "browse and upload" button. And contains an image to view the users uploaded image like so:
<mx:Application
<mx:Script>
<![CDATA[
[Code].....
In my myModel class I have a img_scld_bm that the browseAndUpload() function draws into after scaling it.
My intent is that my mx:Image will display the image. As shown here I'm assigning the image source="mymodel.img_scld_bm", this ends up just showing a broken image icon.
I also tried data binding, where in my myModel class I have [Bindable] var img_scld_bm. And then tried setting my mx:Image source="{myModel.img_scld_bm}" .. that didn't seem to do anything either. All this compiles fine, no warnings. I think in this case, I'm not setting a trigger or propertyChange event to update the binding?
how to correctly bind an mx:Image source to some bitmap?
It might sound like a trivial question but how can I show progress bars, when datagrids and other components that "talk" to web services, update their data providers
View 1 RepliesI think I must be missing a step here; I have different data being pulled from an array created from xml depending on a variable (_currentTrackNum).. and the data changes if I set a different initial value for it; but if I change the variable once the program is initialized, none of the data changes even though I rerun the call with the changed variable.[code]

I have a flex application that repeatedly polls a remote XML file to detect changes, but I've found that once the file hits a certain size, the poll blocks the UI and makes the page unresponsive for a short time.
Is there any way to ensure that the call made to the server or the event from the flash.utils.Timer class runs asynchronously to the main UI thread?
I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.
I have a situation where I need to update a DropDownList's dataProvider and selectedItem in a specific order. See the following code ...
<s:DropDownList id="dropDownList"
dataProvider="{someDataProvider}"
selectedItem="{someSelectedItem}" />
In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.
The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".
what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.
View 2 RepliesI have added a button to Lee's scroller * ; to the 'content' movie clip, inside the scroller. Testing the movie, Flash recognises the mouse click -and doesn't give me any compiler errors- however, the button doesn't function. I am guessing my code isn't well enough written to get the playhead to move within the main timeline, as it is embedded in a movie clip (the content mc) within another movie clip (the scroller mc), perhaps. Using AS3, what additional code do I need to add to what I already have written?
My code for the button:
// handle events for back to menu button ...
btnbacksmilejapan.addEventListener(MouseEvent.CLICK, clickJapanSmiletoMenu);
function clickJapanSmiletoMenu (evtObj:MouseEvent) {
//trace shows what's happening ... in the output window
trace ("The Japan Smile back toMenu button was clicked")
// go to the Menu
gotoAndPlay("scene two jpn");
}
My problem is that my scroller (made by Claudio I think) is working perfectly.. but when I put it inside of a movie clip it just won't show the loaded text. I donno why is it doing.. and I need it to be inside of MC.

I'm using Flex with Cairngorm framework.I have a custom component which I create like this:
<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />
Where the findFriendsPaginationElement is inside the model locator:
public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();
Inside the custom component I have button that uses a property of findFriendsPaginationElement object:
<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>
But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)

I have just successfully displayed the contents of my 'gallery' xml in a grid layout to my stage. My issue is I have a fairly small area to work with and I need to put these inside a custom scroller. The custom scroller I have atm displays only text (via a TextField and URLLoader) from a txt file and I'm confused how to alter it to load my gallery images (from my xml) instead. Can I load images from the XML into the textfield? Is there an easier way of doing it.

I know you can't target movieclips and text inside buttons in AS2, but I'm hoping there's a workaround in AS3. I've been handed a complex world map FLA with about 400 individually stylized buttons (various countries and regions) each with special text boxes in their rollover states. My job is to parse XML and push bits into the respective text area boxes.To simplify as much as possible, I've encapsulated all the buttons in an movieclipcountries_mc) and swapped the individual static text boxes for each country with an 'export for actionscript' classed movieclip (Overlay) containing a text area component (bodyCopy_ta).Kind of like this:-- stage----countries_mc------button (given instance name on stage, listened for MOUSE_OVER event)--------Overlay (shared in library, listened for ENTER_FRAME event)----------bodyCopy_taMy thinking is if I can listen for a button rollover, it seem like I should be able to change the text at Overlay.bodyCopy_ta through an event listener, regardless of where it's been placed on stage.
View 7 RepliesHow can I update the dynamic text content which is inside a button ?
In other words, how can you address a dynamic text inside a button ?
I want to change the text label of a button, on the fly.
Isn't there any other way to achieve this than "making" a button with movie clip instead od a "real" button ? Does that mean Buttons were not expected to have dynamic text in them ?
The answer to my question is possibly easy, yet I haven't found an example of solving it in the web, nor have I found a solution reading ActionScript reference. My problem is the following: I have a big UIComponent derivate element inside a Scroller (spark.components.Scroller) window. The Scroller class is great because when my canvas element, that changes size dynamically, exceeds its boundaries, scrollbars appear automatically and handle scrolling of my UIComponent inside it. However, I'd like not just to be able to Scroll using these automatically appeared scroll bars, but also by using a pan tool that I will myself implement (similar to the hand tool in Adobe software, for example). The thing is that I am not able to modify correctly the element's position inside the Scroller window.
I tried, as a first approach, accessing to my elements' 'x' and 'y' properties, however, when changing them, I dont get the resulkts wanted. The code for it is the following (in which, for symplifying reasons, I used a text label as my 'inside' element, and two buttons as an external scroll controller, instead of a hand tool)
