ActionScript 3.0 :: Removing Items From List Component?
Oct 27, 2008
Below 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?
public function getXMLdata(event:Event):void {
var campXML:XML = new XML(xmlLoader.data);
var vid:XML;
for each(vid in campXML.vid) {
I am working on an older Flash project created in CS3 ActionScript 2.0 How can I make the pointer cursor change to the hand when hover over a list item?_root.slidePanel.myList'myList' is the list. I have traced out the contents of the List MC and it has a child MC called 'content_mc'. I assumed this was the object containing all of my list items but the only members of this MC I can see (when tracing them out) are 'setRGB' and 'searchKey'.
Why I have to press 2 times the arrow key down to get a navigation through the list items in a list component of Flash?
Theres any workaround for this? I have a listener for keyboard event that checks if keyCode is equal to 40 if it is then I use 'stage.focus = list', but I have to press 2 times key arrow down to start navigating through list items.
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.
HOWEVER: I would like that if - for example i am on item 10 and click to item 4 - all the thumbnails between 4-10 are removed. it it possible to dispatch this click event X number of times dependant on the - count value?? FOR REFERENCE: THIS IS THE CODE THAT REMOVES ALL ITEMS BEYOND THE ONE I HAVE SELECTED:
I created an isntant of a list component on stage called "myList" and added 8 items to it.I need to align the labels in this list to the right or center.It's on the main time line and not in a seperate as file (if it matters...).I tried using setStyle but it failed (not the solution or I used it wrong).
I'm having troubles getting selectedItems from a List Component in Flash CS4. Each time I select multiple selections the object that selectedItems returns seems to be populated with the last selected item in each of its instances. What is strange from the example I provide below is that once you've made your selection and click the label you can update another list with the correct selected values. But the output values are still traced incorrectly.
Code: import fl.data.DataProvider; import fl.controls.List; import fl.controls.Button; var dp:DataProvider = new DataProvider(); dp.addItem({label:"Item 1"}); [Code] .....
This question specifically deals with AS3 and list components and styling a selected item, if that's even possible. I've got an XML/Flash Video player that lists the videos with a thumbnail and description in a list component. I got the source files from an Adobe tutorial:[URL]...I'm able to style everything the way I want it. The problem comes when I try to attribute a specific text style to a selected item. I understand how the information is being taken from the XML and looped into the list component. What I don't get is how you reference a particular item in the list and whether or not you can attribute a different style to that item when the event listener fires.
I set my list to allow multiple selection. But when I load data in my list, I want to set a few items as selected. Normally you can set only one item selected by using list.selectedIndex. It only accepts int. How can I set multiple items as selected?
im having some dificulties in the combobox of Flex 3, after defining the dataProvider and filling the combobox, how can i remove the items in the combobox later (without removing items in the dataprovider)? if i set the provider to "" or null, the items in the combobox are still there
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 ?
how to populate a list box component located within a seperate mc in my swf with an array... the array comes from a response from a webservice call. I am not currently on the computer with my source code available so lets just use the following....
listdata[i] = the array i want to populate the list box with..... (listdata1, listdata2, listdata3, listdata4, etc. etc.) movieclip1 = the MC within my fla containing the list box component mylist = the actual list component
... just not all that familiar with the format of actionscript when working with objects... using CS3 and as2 btw,
I'm using flex 4.1 to write an application. i read in the documents that has the rowCount property to set how many items to display. the does not have that property. how can I limit the list to display 3 items ?
The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.
I have a combobox and list component on the stage. The combobox has 3 selections. How do I get it so that each selection triggers the specific xml file to load into the list component? I can't get them to communicate to each other.
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.
I am adding few items dynamically from the library to the stage by creating instances. If I remove them using removeChildAt() then the item gets removed from the display but exists in the memory. How can I remove this from memory?
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
I want to iterate over an ArrayCollection in Flex while there can be items added and removed.
Since i didn't find a way to use a "classic" Iterator like in Java, which would do the job. I tried the Cursor. But it doesn't really work the way i want it to be ;) So how do I do it nicely ?
var cursor:IViewCursor = workingStack.createCursor(); while (!cursor.afterLast) {
How do I remove an items from a data bound array? My code follows. for(var i = 0; i < listBox.selectedIndices.length; i++) { var toRemove = listFiles.selectedIndices[i]; dataArray.splice(toRemove, 1);
Here is my swf. The Add Photos works except when you remove items. [URL] Add 3 photos different. Remove 2nd photo. Add a different photo. SWF adds the 2nd photo to the end.
Here is my code private function OnSelectFileRefList(e:Event):void { Alert.show('addstart:' + arrayQueue.length); for each (var f:FileReference in fileRefList.fileList) { var lid:ListItemData = new ListItemData(); lid.fileRef = f; arrayQueue[arrayQueue.length]=lid; [Code] .....
