Trying to add handling for when the selected item changes in a drop-down. However, the Change/Changing events are fired before the drop down panel closes. This is too soon. I need to do some handling after the drop down is closed with the new selected value.
View 1 Repliesso here is the problem that I have so far. I tried to simplify my code so I can attempt to figure this out, but I have had absolutely no luck. I have a viewstack that contains 1 dropdown per stack. They share the same data provider. What I want to do is to select the item contents from the first one. Once I do that, when I click a button to the next stack I have a function that searches from index 0 to the dataprovider length and if the item from the first stack matches the second one, I want to have the second dropdown pick that item up and display it. I have it matching, and I try to select it, but when I run the application it shows up like nothing is selected. Here is what I have:
edit: I got it to work for a simple example, but when I attempt to use it in my more complicated example, on that button click it for some reason resets the value of selectedIndex to -1. How do I prevent this from happening? This is working code for the simple example

I want to do my stuff on LocationChangeEvent.LOCATION_CHANGE event which is introduced in AIR 2.7 but this event is not getting dispatched.My sample code is below. Please help me know if there is anything wrong that I am doing.

I created a list control at runtime as following:
[Code]....
//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.
If you have a DateChooser control next to a text control and you left click your mouse to select the text then continue holding down the mouse button and letting the mouse button up while over the datechooser control, the selectedDate value changes to the date you are hovering over. I have users that are having issues with this and it happens unintentionally because of the proximity of the two controls. I cannot find a way to stop this effect. Basically I would want the selectedDate to only change if the user actually clicks the calendar control ie. mouseDown or click. Calling functions in those events do not change this behavior. I need a way to disable the control from changing the date on the mouseUpEvent (I think).
View 1 RepliesI have a DataGrid, and what I would like to do, is when a user clicks on a row to select it, check a certain condition, and if it's met prevent the row from getting selected and keep the old selection intact.
View 1 RepliesAnyways, there is a property that changes occasionally to reflect the name of a level in a game (object._I._M.text). It could take a minute to change, or a max of two minutes, depending on how fast all players are able to finish the level.
I want to be able to listen for the change in this property to fire off another function. I have found very few answers to this online, and the examples I have found were very incomplete and poorly written.
I have tried ...
theobject._I._M.addEventListener(Event.CHANGE, myfunction);
I just want to know if there is any TextChange Event or equivalent to that in AS3? I am currently using Adobe Flash CS3 with my AS3 files and I have to detect whether or not my TextTool's value has changed or not. With my data being integers ranging from -4.440 to 3.560, I obviously cannot use the != operator.
View 1 RepliesI'd like to display tool tips, once the user holds his mouse on an item of an opened combobox.Ifyou open the drop down list of a combo box, you'll see a list ofelements/items. Each of them can be accessed e.g. viamyCombo.getItemAt(0) .To me it seems I only get an object with adata and label property. But I think there must be more to it, becausewhen you hold your mouse over a sub-element, it'll be highlighted. Thismeans that there is some event listener on that very single item. Sohow can I do this?[code]
View 3 RepliesI have an XML object like this[code]...
but how to add the id attribute as the 'data' field of the dropdown so when an item is selected, it returns that field?
Why won't this ENTER_FRAME event stop firing when I call view_stats_exit before going to view_start? public function view_start [code]
View 1 RepliesI never realized that fl.getDocumentDOM().selection doesn't retain the selection order... <sniff>. I was hoping to build relationships based on the order. I guess I took if for granted that tools like Maya and Max store the selection buffer in order of what was selected. I'm trying to avoid: Select Object, <Press 'Parent' Button>, Select Parent, <Press 'Parent' Button>
View 2 RepliesI'm having with a menu navigation system. I'm using Flash MX. I have created a menu system for the site I'm building ([URL]) where one of the buttons "Choose photographer" drops down a list of names. All the other buttons just jump to another page. The drop down is currently using tweens also the logo moves to the left as the dropdown appears and returns when the dropdown returns. All working fine apart from its a bit jerky.
It's I just wanted to get away from tweening and use action scripts instead, as I'm a newbie to all things Flash I trawled the net for tutorials and examples so that I could cobble together the exact same effect. I have managed to get the drop down work and return using the action script and it does seem smoother and works slightly better. But can I get the logo to move to the left and back in time with the drop down...no.
I inherited a custom component from TextField. The component needs to know when any of its styles got changed at runtime via setStyle. How would I do that? It's probably obvious but I couldn't find an event or appropriate method to override.
View 2 RepliesI'm implementing some kind of combobox control (by extending spark.components.supportClasses.DropDownListBase)
Now, inside this control; I need to know:
If the dataprovider is changed/assigned. (which I can do... the first approach below works); if any item in the dataprovider collection has changed.
I tried 2 methods that did not do the trick...
1ST APPROACH:
2ND APPROACH:
UPDATE: Edited above.. The first approach lets me know if the dataprovider is changed but not if any item is updated in the dataprovider collection. The second approach does not work at all..
i am attaching a number of _mc (my_mc) with a for loop. Inside each my_mc is an input textfield (my_txt)I want to click on my_mc.my_txt and select the textfield .the following code allow this and i can enter text from the keyboard however I want to add text from a _mc keybooard on screen (here called myBtn_mc).As soon as I click on myBtn_mc of course I lose focus ... i have tried to use a variable (select) to keep scope&focus
View 6 RepliesShort version: ComboBox's dropdown works and renders properly before fullscreen, but not during or after. I'm not totally sure how to ask this, so I've actually made a page demonstrating the error, with a very simple Flex app, and all three directions you need to experience the problem yourself.
For those of you not daring enough to follow my link above, I'll do my best to explain here. I've built a rather extensive Flex application (not the one in the link) that has some graphs and charts and checkboxes and other controls for those charts. At the bottom of app in a few of the application States, there is a ComboBox (like a <select> tag in HTML). Because this is at the very bottom, when you click it to access it's dropdown menu, Flex thoughtfully has it come out of the top.

We are rewriting our multiscreen game from Flex Project to ActionScript Mobile Project (root object is flash.display.Sprite and not spark.components.Application). Aim is to increase performance on tablets and have better overview what exactly is going on, what listeners are added and so. (I just don't trust Flex in this.). Do you know any alternative for DropDownList and/or DataGrid? I can't use MinimalComps, because there are little options to customize.
View 2 RepliesI have a project in which i need to pop up an alert to the user before a combobox value is changed. This feature is to allow the user to stay in current state if modifications were not saved. Meaning that the user will be able to cancel the change. I have sub classed ComboBox and tried to hook on ITEM_CLICK of ComboBox.dropdown but this event is triggered after the value is changed. Also, I've tried MOUSE_CLICK ans MOUSE_DOWN but without success.
In my code, I have added a "preChange" event to my CustomComboBox. This event should be triggered before a change is made. Also, I've introduced a method called commitChange that will be called manually to actually commit the change.
I am developing an AIR application and I want to change my project theme to one of the additional included themes that is packaged with Flash Builder 4. So, I went to the Project Theme and changed it and it looks like it is supposed to in the Design View. When I run the application, the components (eg: a button) themselves look like it is supposed to, but the application's background is just white instead of the displayed color in the design view.
View 2 RepliesI have an editable grid and would like to update values based on the edited cell and I am doing this in the itemEditEndHandler such that when they finish editing a cell I update other cells that are dependent on it. the only problem is in the itemEditEndHandler the new value has not registered yet. If I try and get the value of the cell i find that its still giving me the old value and not the new value that I have entered.
View 2 RepliesI have a weird problem with verticalScrollPosition in Flex.I have a content Canvas and a wrapper Canvas. The content is large (5000px X 5000px), the wrapper is 800px X 800px.
public var wrapper:Canvas = new Canvas();
public var content:Canvas = new Canvas();
wrapper.addChild(content);
application.addChild(wrapper);
I would like to set the wrapper's scrollbar position dynamically anytime. I can do it by calling its properties:
wrapper.verticalScrollPosition = A;
wrapper.horizontalScrollPosition = B;
This is working fine. But! If I set a default scrollbar position when the Canvas is complete:
wrapper.addEventListener(FlexEvent.CREATION_COMPLETE, function(e:FlexEvent):void{
wrapper.verticalScrollPosition = DEFAULT_A;
wrapper.horizontalScrollPosition = DEFAULT_B;
});
I can't set the verticalScrollPosition anymore:
wrapper.verticalScrollPosition = C;
trace(wrapper.verticalScrollPosition); // Outputs: DEFAULT_A
So the problem only exist if I set a default position using 'FlexEvent.CREATION_COMPLETE'.
I have an image which its source depends on a bindable property of another object.I'd like to know when this source changes, for example, by capturing the bind event or another related event of the Image control.
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:
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"

I'm creating a webpage, and I have made some buttons.Image 1 is the homepage, which is frame 1 in Flash.Image 2 shows that when I rollover the button "Portfolio,"I get a dropdown menu.I have this set as frame 3 in Flash.Image 3 shows that I've gone down the dropdown menu and rolled over "Photography." But if I rollout of any of the things from the dropdown menu, it stays at Image 2 (Frame 3)with the dropdown menu visible. Which is a problem...I want to be able to rollout of these buttons to revert back to the homepage, Image 1 (Frame 1).But, for instance, telling "Graphic Design" to go to Frame 1 on rollout means that if I try to go below "Graphic Design" to "Photography," I've rolled out--and so the rest of the menu disappears.So I want to roll be able to select anything from the dropdown menu, and only rollout to Frame 1 if I go outside the entire dropdown menu, not just one button.

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

I have many dropdowns in my flex application. Now I want to set rowCount property so that as many rows as possible so there is less scrolling when see the dropdown items.The flex application was running on a popup window. So I think I have to know the distance from dropdown to bottom border of window, and then calculate what number should be for the rowCount. Like Height/per row height.As I known, the dropdown.y is the relative y coordinate of itself. But my dropdown has many parent UI layout component, and also I have many dropdowns, it is hard to calculate one by one.

I'm trying to change the position of the dropdown list relative to the combobox item.Setting the position using comboBox.dropdown.x = 1337; doesn't work...
View 1 RepliesBackground: I am doing some UI work where I allow the user to programatically add and resize controls on a canvas. Problem: When resizing a combo box through AS the dropdown stays at the same width as the first time it drops down. So user places combo box on the page, clicks the down arrow, sees the options, selects an option or clicks down arrow again to close, resizes the width of the drop down, clicks the down arrow. Now drop down is the same width as original. Have tried simple things like setting the width of the dropdown specifically and invalidating display list but it still doesn't work.
