Do I need to create all objects which i will possible use with itemRenderer in createChildren function, even if the current item must not show some of them ?
View 2 RepliesI have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">
Image's paths are in the xml file. I make a loop to load images to the Display List.
So if i have a loop:
ActionScript Code:
for(var i:int=0;i<xmlList.length();i++)[code]....
after it is done i would have access only to the last imageLoader instance. How to get access to the rest of images, which were added to the Display List with the same name "imageLoader".I tried to call it with the imageLoader.name property,but surely i do something wrong, as only errors appear in the output panel.
I have a script that randomly pops out circles all over the stage. However, I want them to disappear once I roll my mouse over them (and only the ones I roll over, not all the instances).So if I have code like this in a function:[code]And then I have a mouse_over function in the same class, how do I tell it to removeChild? Since the stars are instances of the object, they are giving instance names like instance67, which makes them hard to remove.

I want to call the parent function called "edit_groups()" from the itemRenderer. The code for my itemRenderer is:
<mx:VBox id="vbx_container" paddingBottom="4" paddingLeft="4" paddingRight="4" paddingTop="4" borderStyle="solid"
dropShadowEnabled="true" width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >

<mx:Image id="image" width="100" height="100" source="{data.thumb}" scaleContent="true" maintainAspectRatio="true"
complete="{image_smoothing_handler(event);}" trustContent="true" doubleClick="{Call The Parent Function"edit_groups()"}"/>
</mx:Canvas></mx:VBox>
And I call my itemRenderer from an application like:
list_groups_modify.itemRenderer=new ClassFactory(groups.list_groups_modify_item_renderer);
<mx:Label text="{data.label}" textAlign="center" maxWidth="60" toolTip="{data.label}"/>
I am having an issue with my ItemRenderer, which I am using for a spark List. My code is the following:
I have this list:
<s:List
id="productSetList"
dataProvider="{ model.productSets }"
[Code]....
The thing is, if I scroll the list, and click on an item, it does not trace 'arthur' ! Why is this so ? I must trace that all the time that someone clicks in the list!
EDIT: If I remove change="model.selectSet( productSetList )" in the list, it works!! but I cannot remove that, some suggestions ? How can I switch that to another function?
I have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

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.
View 1 RepliesI have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
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").
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?)

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".

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?

What is the Difference between ItemRenderer and ItemEditor?And When ItemRenderer is initializing and loading?
View 1 RepliesI've created a custom ItemRenderer extending UIComponent and implementing IListItemRenderer. This renderer contains a Text-Object to display the value.
For editing I'm using the standard ItemEditor (TextInput).
Now, when I want to edit a value, I click on a cell and the editor is created. But instead of displaying the value which was displayed in the renderer, "[object Object]" is displayed.

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" />
