Flex :: Cannot Access Constant Through ItemRenderer Using ParentDocument?

Jan 18, 2011

I have an itemRenderer inside a dataGrid, and I am able to access variables on the mxml file (in a *.as script file referenced from the mxml) using parentDocument. However, I am unable to access a constant in the same script file. If I change the constant to a regular var, I can access it. I created a getter function for the constant and it works, but why can't the constant be accessed directly?

Flex :: Access ItemRenderer Of A Selected Item?

Feb 3, 2010

I have a TileList with thumbnail images. Under each thumbnail images I display the name of the image. I want to build rename functionality. So under the TileList is a "Rename selected image" button.

When this button is clicked, I would like to change the state of the itemRenderer component. The label underneath the image will change into a TextInput so that the user can type a new name. This is much like the Windows rename file functionality.

How can I access the itemRenderer of the selected image? How can I make it happen that it listens to the click event of the Rename button?[code]...

Flex :: Displaying List Of Flex Progressbar Using Itemrenderer?

Sep 25, 2010

I want to create a list of progress bars and update the list accordingly.I have group data in an Array as

<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....

The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as

<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>

Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").

Flex :: Navigate Within An ItemRenderer?

May 11, 2011

How can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.

Navigation within a View (Easy)

<s:View>
<s:HGroup >
<s:Button label="Questionnaire" click="navigator.pushView(view.QuestionnaireCategory1View)"/>
</s:HGroup>

Navigation within a Item Renderer (Impossible?)

Flex :: Add ItemRenderer On The Fly On Component?

Jun 21, 2011

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.

What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.

And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.

Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".

<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"

Flex :: Datagrid With RadioButtonGroup Itemrenderer

Aug 12, 2009

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?

It is ment for dynamic questionnaires.

Flex :: ColumnOrder With Formatter And ItemRenderer

Mar 25, 2010

I have a advanceddatagrid that has around 15 columns. Some are string, some are numbers. I have shown 4 columns below. The number columns have formatting done for zero precision and 2 digits precision. The itemRenderer is just to show Blue Color if the number is +ve and Red Color if the number is -ve. It looks something like below

<mx:columns>
<mx:AdvancedDataGridColumn dataField="Name" textAlign"left"/>
<mx:AdvancedDataGridColumn dataField="Time" textAlign="right"/>
<mx:AdvancedDataGridColumn dataField="Score" textAlign="right" formatter="{zeroPrecisionFormatter}" sortable="true" itemRenderer="ColorRenderer" />
[Code] ....

How can I save and reload the Formatter and ItemRenderer data. I am having trouble saving the formatter and itemrenderer and reloading it again. How can I reshuffle the columns but can preserve all the properties of it to through sharedobject and recover it again.

Flex Can't Interact With Button In Itemrenderer

May 28, 2010

Flex :: Adobe Combobox As Itemrenderer?

Jun 12, 2010

I have a flex combobox as a datagrid itemEditor. However, after selecting an item in the combobox, its necessary to click out of the combo (i.e. into another cell or elsewhere in the app) for the value to be committed to the combo. Prior to this, the combo sits 'proud' of the datagrid and the value hasnt actually been committed.

Is there a way to force the value to be immediately committed after an item has been selected and for the combo to 'lose focus'?
