How can access each item on a HorizontalList component

Hello

I would like to know how I can access each element on a HorizontalList component. What I want to do, it is something like this:

My HorizontalList:

< mx:HorizontalList
low = '0 '.
backgroundAlpha = "0.0".
ID = "catalogoOpciones".
columnCount = '3 '.
Height = "80".
hideEffect = "{esconderse}.
horizontalScrollPolicy = 'on '.
Selectable = "false".
showEffect = "{mostrarse}.
Width = "100%" >
< mx:itemRenderer >
< mx:Component >
< mx:VBox height = "100%" verticalGap = "0" horizontalAlign = "center" >
< mx:Label id = text = "{data.nombre 'title'}" textAlign = "center" styleName = "nombreOpcionDetallePlato" / > "
< mx:ComboBox id = dataProvider = "{data.opciones 'seleccion'}" labelField = 'label' labelFunction = "funcionLabelComboBox" styleName = "comboOpcionDetallePlato" change = "dispatchEvent (new Event ('cambioOpcion', true))" / > "
< mx:Script >
<! [CDATA]
public void funcionLabelComboBox(item:Object):String {}
Return item.label + ", $" + item.precio;
}
[]] >
< / mx:Script >
< / mx:VBox >
< / mx:Component >
< / mx:itemRenderer >
< / mx:HorizontalList >

What I want to do is to show on a screen to alert the index selected in each ComboBox on the horizontallist control:

for (var i: Number = 0; i <. horizontalListt.dataProvider length; i ++) {}
var index: Number = (horizontalListt.dataProvider.getChildAt (i) as ComboBox) SelectedIndex;
Alert.Show (index. ToString());

}

I should add that the horizontalList works fine, the only thing that gives me problems is access to every item in the list.

I thank very you much for your time and your help.

You usually (very close to always) to change the data of dataProvider when list items base change of components. For the ComboBox change manager should do. List based components recycle their converters point, you have to run to the data.

  • How can I select all instances of a component in the timeline at once without manually shift clicking on each instance?

    Title says it all!

    How can I select all instances of a component in the timeline at once without manually shift + click each instance?

    The reason why I want to do this is because I have a video clip with MANY quick cuts. So the clips are cut out and splattered everywhere. I'm color correction now and so I want to be able to select a clip around wherever it exists in the timeline so I can drag the effect on all the at once, without having to search each occurrence of the item in the timeline panel. This lot "select" would make it so I don't miss not all instances of the clip and saving a ton of time going through the timeline and Shift clicking whenever the clip is also up.

    I hope that the PP is smart enough to do this

    Thanks in advance!

    -Tim

    Choose a single instance of the element, perhaps even the first bit... and use the new Master Clip feature... Firstly here is a written explanation and a video tutorial on this operation... This is a great feature.

    How can I save items on a USB key with Vista

    Plug the Flash drive.  Go to start / computer and find your USB drive listed there.  Find what you want to record on the FlashDrive (from other units identified in Explorer) and copy / them (CTRL + C) and then go to your USB key and click it to open it and press Ctrl + V to paste the files.  That's all there is to it.  You can create folders to store files, like flash drives have limits on the number of files can be stored in the root directory (but not folders).

    I hope this helps.

  • How can I delete items from a 2D array?

    Hi all!

    I asked a similar question in the past, but I'm looking at a slightly different scenario now. I have a chart 2D of 8-bit values which form a video image, but I'm trying to remove a number of the highest values in the image. In order to avoid the image of being horribly ejected, I thought that I would like to replace these with NaN values. While I thought it would be simple, I had problems to access the items in the middle of a 2D array. I have attached my code, but I fear it will not be that useful, it was something of a poor attempt (but this is my most complete).

    Thank you for your time ,.

    -Gobble

    First of all, eight bits (U8) have not NaN. Are you using the correct representation?

    You can substitute a zero (for example) instead.

    Here are two simple using tables DBL ways, because that's what you actually have. Modify if needed.

  • How to access each present line attribute in a view using Expression Groovy accessor.

    Hi Experts ADF,

    JDEV version 12.1.3.0

    I have a use case where I have a table based on the ZZVO1() View object. In a table, one of the column there is calculated one and only X column based on the database column.

    I have a view accessor (XYZVO1 ).

    How can I subtract ViewAccessor(first row) - X (first line) column and display it in the column attribute Y.

    Column of Y = XYZVO1("Gross")-ZZVO1("X") - 1st rank

    Column of Y = xyzvo1("gross")-zzvo1("x")---deuxieme row

    -----------                                                             ---------------nth row

    here XYZVO1 is the view

    and ZZVO1 is the orginal VO containing X and Y.

    Please suggest some of your views.

    Thank you

    Roy

    You can follow this blog Andrejus Baranovskis Blog: Groovy with a view link accessor which shows how to use groovy to access an attribute through a link in the view.

  • How can access a button inside the video clip

    I have a button named a_btn. This button is located in a clip name a_mc passage. This button is on the first frame. then when you write the code for that:

    function submit(event:MouseEvent):void

    {

    trace ("hii")

    }

    a_mc.a_btn.addEventListener (MouseEvent.Click, Submit);

    his work. but when I keep this button on 2nd chassis or anywhere not in 1 frame inside that movie clip, then I get error runtime as:
    TypeError: Error #1009: cannot access a property or method of a null object reference.
    to NewFlashDocument_fla::MainTimeline / NewFlashDocument_fla::frame1 ().
    How can I access this button on the second picture...

    You cannot reference an object until there are.  Thus, if a_btn is on the 2nd frame of a_mc, you must wait until this 2nd frame plays before trying to refer to a_mc.a_btn.

    If not, put a_btn on the first image and set its visible property to false in the first frame and true as part of the 2nd.  Then you can use your current code and duplicate the design you are trying to achieve by moving the button on the 2nd frame.
