View 6 Replies3-rd day goes to waste. And soon I'll be mad. I cannot correctly do it despite the Adobe's topics (e.g. [URL]). But I need:
1) the user can enter the word (first sign - the Letter);
2) the entered item is added to the List of CheckBox;
3) that List can be correctly sorted;
4) WHAT I CANNOT MAKE: to be able to correctly remove the selected item. All indices after removing must properly changed:
so, if I removed the item with index '4', the next indices would be descended (5=>4 etc.). How can I achieve it? You may have a quiet laugh over my desperation,

I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.
Have a quick question, have a xml file like that:

I'm using the xml connector to retrieve the results then bound the items array to the dataprovider No problem to access the items but my question is how to access to var1 and var2 in actionscript. Could i bound it to a var?

View 1 RepliesI'm currently working on a project where I have a user defined list of urls which is saved in a local SO. When the movie is loaded the ComboBox is populated with the values from the SO (Stored as array inside SO).I want to give users the option to remove items from this list. So far I have managed to remove the selected item from the combo box, clear out the SO and loop the remaining ComboBox items, but, when I try and load these item into an array to parse back to the SO, the array is created and creates the correct amount of elements, but, each element is populated with only the data from the 0 index item of the ComboBox.My code so far: (This sits inside a button component and is invoked onClick)
_root.ComboBox.removeItemAt(_root.ComboBox.selecte dIndex);
_root.ComboBox.selectedIndex = 0;
_root.local_data.clear(); [code].......

I have tried already with toggling visibility and 'gotoAndStop()' to make items appear over other items when the corresponding button is pressed, for example, when the user tries out different pants/shirts on their character.
I would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.

I'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?
The following for loop removes children from their parent if they're in the display list. It works correctly, but I also want to remove each child from memory with the same loop.
View 1 RepliesBelow is a function set that's used to get info from an XML source(s) and populate a List Component (videoList). Works great. The second function loads data from a separate XML source and populates the SAME List Component. When the second function is called it loads the data in addition to the existing data into the List Component. I want it to REPLACE the data. How would I accomplish this?

I have a Listbox whith a ArrayCollection as datasource. I'm trying to remove the selected items from the ArrayCollection to update the list.Here is how I coded the remove function:
for each (var item:Item in theList.selectedItems)
{
theArrayCollection.removeItemAt(theArrayCollection .getItemIndex(item));
}
This works fine as long as the ArrayCollection is not sorted. When I apply a sort I get a RangeError from ListCollectionView.removeItemAt.
I could pop, shift, splice or slice it out of there (hey, that had a nice ring to it...)

I am trying to create a combobox where the items listed in the combobox are font names and each item will display using the font of the item label. For instance, one item label in the list is "New Times Roman" and I want that particular row in the combobox to have the text AND font of "New Times Roman". For some reason, inside of my custom CellRenderer class, I cannot seem to find a way to get the item label that corresponds to the CellRenderer and the CellRenderer.data item always appears to be null!
This is the code I am currently using:
//From the main class, I am creating an instance of the
CustomizableComboBox and adding in the font names I am interested
in.

I need to add accessibility to a flash program which I have created. I can make the screen reader state all of the different buttons and at the top level of a combobox. However if I traverse the combobox none of the items are mentioned by the screenreader. I've tried various things down to trying to set the accessibility properties of the combobox items as though they were an array
cb[0].accessibilityProperties = accessProps0; but nothing seems to work.
I have a large swf that is embedded in Director as a sprite I now want to put it onto a web page, so file size is critical Is there a way to remove unused library items when publishing so that file size is reduced? Is there another way to compress the swf so it is much smaller?The current size is about 25 Mb.What about streaming the swf?I'm not talking about streaming video or audio, just any Flash content.In Director, there is a way to right-click on a cast member and choose "find in score".If something isn't found it means that it either is not used in the movie or is implemented through code
