Is it possible to make an item in a List control not selectable? If so, how would this be accomplished?
I've tried one thing so far. What I did was use a custom item renderer that checks for a value in the data property upon a FlexEvent.DATA_CHANGE event. If that value is not set, I tried setting the item renderer's selectable property to false. This, unfortunately, does not seem to work.
Is it possible to have 4 list boxes but only let the user select one item from all four list boxes? If so how?

The following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows. However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this?
<mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" >
<mx:itemRenderer> <mx:Component>
<mx:VBox width="100%" height="150" >
<mx:Text text="{data.commentContent}" />
<mx:Text text="{data.username} ({data.modified})"/>
</mx:VBox> </mx:Component>
</mx:itemRenderer> </mx:List>
To be more clear, I don't want to set the itemRenderer's VBox height to "150" or any other fixed value - but it'll only show one line of the text if I don't do it. So I'm looking for a way out of this. (If the VBox is not inside the itemRenderer, it'll auto adjust height as Text field string length grows - that's what I want.)
I have a list component and I have an item editor for the items in the list. I would like to have a button that the user clicks once they are done with their changes because I am having them edit multiple pieces of data in the editor and I would also like to validate the data before closing the editor as well. I just don't know what to do on the button's click event to make the item editor close and commit it's changes to the data provider.
View 3 RepliesI am trying to make a generic list control that has x buttons in it so that users can remove items from the list by clicking the x button. However, this list control needs to support item renderers while still standardizing the layout of items placed next to x buttons.
So I figure the best approach would be to extend the list control and use a renderer that draws the x button and combines that with what ever renderer the user supplies. Unfortunately I cannot figure out how to do that.
I tried overriding newInstance method from the IFactory interface and used that to create an HBox that contains my button and inserts the newInstance result from a user supplied renderer, however it wasn't complete. It displayed as I expected, but the mouse over effect only worked on the user supplied renderer portion and not the entire HBox that my custom renderer made.

I have an exhibitor list that loads from xml...and I have a booth layout that loads from a separate xml...I have two arrays set up so that the rented booths are stored first, and the exhibitors are stored in a separate array side by side...
if you click on an exhibitor in the list you will see the associated booth highlight in the mainwindow (and minimap too)...however if you notice, there are multiple entries in the list for some exhibitors, this is because they may rent several booths...I want to condense the exhibitor list to have one entry per exhibitor, but have the entry control all their booths, so if you click an exhibitor with 2 booths both of them would light up even though there was only one entry in the list...is this even possible with the list component provided by flash?
i'm in a situation where i need to iterate through each item in the list control and get the data from it.
how would i get a handle to an item at a specific index? I've tried getItemAt() but it throws error 1061.
I'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer {
[Embed(source="/assets/trapezium_alpha.png")]
private static var TrapeziumMask:Class;
private static var trapeziumMaskInstance:BitmapAsset;

Is it possible to make a LinkButton selectable? That is, the text from the LinkButton can be selected and then copied. LinkButton does not have the selectable property.
View 1 RepliesAs part of requirements for a new feature of "locking" a page, it is desired to have all elements on a locked page be non-selectable. This is not to be confused with disabled. All elements should appear as if the page were active, but not be selectable.The current thought is to create a clear canvas and place it over the existing elements. With this thought, I have two questions:if you can think of a better way to make all items non-selectable than applying a clear canvas element over the existing elements could you describe it?if not, what is the best way to retrofit existing implementations to accept the overlayed canvas item? BTW, all .mxml pages inherit from a custom .as file.

When would you want to use removeAll() vs just new ArrayCollection when you want to clear an array collection. Remove all iterates though each item in the list. I can't see a case when I would want to use it.
View 1 RepliesI have a List with textInput as itemrenderer. Initially the list is loaded with data from a data provider. However since the items are rendered in textInputs, I have the ability to change the value of a particular item.
But when trying to access the value of the changed item using the function below, I still get the old value in my trace:
private function addItem(event:Event):void {
trace(myDataProvider.getItemAt(myList.selectedIndex).label);
}
what I need to do for the new value to be available. My itemrenderer is shown below:

I have a List and the item renderer displays an image. Whenever you scroll the list, and the item renderer refreshes, it redownloads the image. Causing there to always be a delay. Is there some way of caching it so it doesn't have to redownload every time causing a delay in showing the image every time you scroll the list?

View 1 RepliesIn Flex 4, I have a Spark List component with item renderers. I would like to select an item in the List by clicking on it, and deselect it also, by clicking on the same selected item. Like an on/off switch.
My item renderer has the following states:
<s:states>
<s:State name="normal"/>
<s:State name="hovered"/>
<s:State name="selected"/>
</s:states>
so I tried to add a click event listener to the item renderer with:
private function selectUnSelect():void {
if (currentState == 'selected') currentState = 'normal';
else currentState = 'selected';
}
with an awkward behaviour... where the item stay selected even after clicking it again in the selected state.
Think of using the List component without the Command (on mac) or the Control button on windows.
I'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).
I'm trying to have multiple item renderers in a list, as I have several different types of objects that I want to display. I tried creating a new class that extends ListBase, and adding override public function createItemRenderer with my code within this function. I then instantiate the new class and give it my array of data as its dataProvider, but createItemRenderer is never called within my new class,
