Flex :: Why Does TileList SelectedIndex Not Get Updated
Aug 14, 2009
In the code below, the presentedAlbumIndex is used to control the selectedIndex of the TileList. Item "five" is initially selected. Whenever the button is pressed the first item in the array is deleted, and the presentedAlbumIndex is decremented.
In theory, the selected index should stay with "five" every time the button is clicked (until "five" is itself deleted). It works this way for the first button press. However, on the 2nd button press the highlighting changes to "six" for some reason. Also, the TileList selectedIndex is always one behind.
I tried looking into ListBase and monitoring selectedIndex. It looks like the selectedIndex is updated initially to the correct index, but then it reverts back at some point to the correct index+1. I do not know why it's setting back.
It seems it's due to the fact that I am doing a data provider delete and index change in the same operation.
Is there some function in TileList I could override to keep selectedIndex up to date?
Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
has anyone made a Custom Skin for a TileList component in Flash CS5. I want to change the scrollbar of the TileList, i want the track bar as just a thin white line and the thumb a orange circle, this for a Touch Interface.
Isn't there a better way to accomplish this?[code]...
All I want to do is make sure that when I update the item that the comboBox is pointing to internally, that it's selectedIndex also update so that the label within the ComboBox reflects the new value.
I am drawing a cellular automaton simulation on a Flex Canvas. I alternate computing the state of the automaton with updating the graphics on the Panel. However, the updating of the Panel does not seem to be "keeping up" with the update of the CA state.
I'm wondering whether I am doing something wrong with my handling of the graphics code. The code is below. Sorry it's so lengthy, but I don't think the problem will happen with anything simpler (well, it probably will, but I'm not certain I want to take the time to find it).
In my TileList, I want to select the TileList items on rollover, as opposed to the click event. I already have the TileList setup to allowMultipleSelection = "true".
I have 2 TileList component in my Flex application. 1 tilelist is filled with data much like following xml sample: <person name="Test"> <likes>Flex</likes> <likes>PHP</likes> </person> <person name="test2"> [Code] ..... data shown is the preference.
The user can click the first tilelist and then the items that person "likes" should be selected in the second tilelist (in other words they lit up). Click event on my first tilelist private function highlightPreferences(e:ListEvent):void{ trace(e.currentTarget); //and now I'm stuck }
I have an associative array that I want to display using TileList. However, it doesn't understand what is being fed to it. All I got is [object] in the TileList.
[bindable] public var people as array = new array(); private function loadArray():void{
I am navigating the items of tile list using next and previous button. I need to highlight the first item in the tilelist by default ( like the first item is being selected by default)
problem-1:In php we can easily move one page to another and easily use different type of function from those pages.In flex3 how i can use different type of .mxml pag
I have two tables: Person {pID, pName, deptID} and Departments {deptID,deptName}An SQL statement like this gets me the name of a person and the department name:
SELECT pName, departments.deptName FROM people INNER JOIN people.deptID = departments.deptID;
The above works fine. I have a Flex DropDownList that is populated with deptNames. When I click the submit button, I am able to obtain the ID of the selected department without problem:
protected function button_clickHandler(event:MouseEvent):void { person.pName=pNameTextInput.text; person.deptID=pDepartmentDropDownList.selectedItem.deptID; //ID of selected department obtained correctly. if (person.pID == 0)
[code]....
From the comment above, I see that adding person will indeed add the attributes of the person object to the datagrid, except that one attribute is a foreign ID (deptID) from departments.
Is there a way to have the TileList component to auto-size to its contents? I have tried setting it 100%, but it seems that won't help. I don't want to hard-code the height because the content will be vary, and I don't want scrollbars to show up.
I'm working for the first time with a TileList and an itemRenderer and I'm having a bit of trouble getting the information from my array collection to display Here's what I've got
private function loadData():void{ var stmt:SQLStatement = new SQLStatement(); stmt.sqlConnection = sqlConn;[code].....
how I go about pulling the information from the array and putting it into labels like username, userjob, userbio ect, Inside the TitleList and itemRenderer.
the problem is the creationComplete event is not fired for each PageImageRenderer, and it is fired only for the tiles visible at start so the rectangles drawn in initComponents() is only drawn for those tiles with valid values, and when I scroll to next row using scrollToIndex() function the rectangles are shown with previous values. and no initComponents() is called for these tiles? however the data.name, data.class are correctly displayed but not the rectangles, why it is so? What is the proper event against which I should call initComponents()?
I have prepared a simple test case for a PopUpButton opening a TileList with black and red entries and it mostly works, but has 2 annoyances. I've searched a lot, tried several variants (added [Bindable] members in my renderer; added color member to the bids array; created my public override set data() method; ...) and has been getting some answers too, but they are way too general.
1) Scrolling "tl2" right-left doesn't work well: the entries are displayed in a mix of red and black. I know the TileList reuses itemRenderer, but how do I fix the problem?
2) In debug-mode I get numerous warnings: warning: unable to bind to property 'label' on class 'Object' (class is not an IEventDispatcher)
I'm using the TileList in a Flex 3 website. I need to set the rowCount and columnCount to factors of the total number of items in my array. For example, let's say that there are 15 items in my array. Then, I'd like to set the rowCount to 3 and the columnCount to 5 (3x5=15). Or if I had 16 items in the array, then I'd like to set the rowCount to 4 and the columnCount to 4 (4x4=16). The problem is that the length of the array varies. It's pulled from a database.
I want to create a tilelist in which there would be different canvas or vbox etc, and i want to make them drag able.I wrote a code to do this, but the output does not shows anything in a list.
i am working on an aplication using flex,adobe air...i have a datagrid with a XML as my dataprovider...during the execution of program my XML is updated....after XMl is updated and saved my datagrid should also get update..I have used Dataprovidername.refresh() method but it is not working.
I have a MovieClip which is just a progress bar animation with about 100 frames. Then I load a zip file using a URLStreamLoader and subscribe to the ProgressEvent.PROGRESS event. After loading starts I receive notifications correctly and I set the bar's corresponding frame using gotoAndStop(). Everything seems to work fine except for the animation not being visually updated.
It seems that the scene won't refresh until the zip file is fully loaded.
I setup Cruisecontrol to auto build a flex project every 1 hour using FlexAnt. The build itself works great - I can see when the project build fails/succeeds in the console perfectly well. But the cruisecontrol dashboard is not updated for the flex project.I have the sample connectfour project, and when it fails, I can see the red box for the project in the dashboard. This does not happen for my flex projects.
Is there a way to detect the value change in HSlider (in Flex 4.0) without touching the slider.Basically, what I wanted is to detect if the slider value was changed programmatically.
I have a TileList that's loaded with data from Flickr. The tilelist uses an imageRenderer to make a bunch of thumbnails. I'm trying to create a custom drag and drop function, but I want to get the image source of the tilelist mouseEvent target. Here's what the code looks like for the drag handler:
