I created a custom component that is a s:SkinnableContainer. I want the background and other items to fade out when this component is visible. Something similar to what happens when calling Alert.show(..) so the Alert box is in focus and everything else is faded out.
View 2 RepliesI'm currently building a Flex 4.5 mobile project including several views and custom written MXML components that can be incorporated dynamically into those views.How do I determine which component currently has focus, namely has been activated by the user tapping on it? The background for this is a global search function in the main application. Depending on the results of this search, fields in the custom components are set. Given that I don't want all components in a view to listen to the outcome of that search function, I have to check which one is currently active.I'm trying to bind the selected object (the result from the search function) to the active component.
View 1 RepliesI have a custom TextInput that listens for the FocusEvent.FOCUS_IN and FocusEvent.FOCUS_OUT events:
textDisplay.addEventListener(FocusEvent.FOCUS_IN, onFocusInHandler);
textDisplay.addEventListener(FocusEvent.FOCUS_OUT, onFocusOutHandler);
My onFocusInHandler function basically removes a "promptview" that tells the user to type in a value, with the onFocusOutHandler doing the opposite.
For example, if the TextInput text was backspaced to a blank value and the user clicks out of the TextInput box, it would show a "Please enter a value" light-gray prompt in the TextInput.
This works fine until the user clicks our custom "Clear" button. The clear button sets the text to "", and I can tell the FocusEvent.FOCUS_OUT is received because the prompt text is set to visible (its not being set anywhere else). The problem is, the cursor remains in the box as if it still has focus, so if the user immediately starts typing, both the prompt text "Please enter a value" and the user-entered text appears over the gray text, which looks pretty ugly and unreadable.
Why does the TextInput receive the FocusEvent.FOCUS_OUT event if it's not actually losing focus?
I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
package {

my issue here is if you use this component you will see that the text is bunched up into a very small area. It does not fill the entire width of the linkButton.
I need to make an auto complete component in flex that fetches the auto complete results from a remote database using a webservice. I have the webservice and querying part worked out. I've already made custom components in action script by extending VBoxes. However I cannot figure out how to generate the popup window that is supposed to show under the text input in my auto complete text box.

I'm trying to write a custom fadeTo(component, x, y):void method, which takes an arbitrary Flex Component as an argument and moves it to a given location, but smoothly.
The problem I'm running into is the following.
I want to send the component itself as argument, like this: (using Button as an example only)
fadeTo(myButton, 200, 500);
(this should move myButton smoothly from its current position to the position indicated as parameter)
However, I don't really know what type an arbitrary Flex Component is. How should I handle that?
I use this code to create and show a MessageWindow:
var newTitleWindow:MessageWindow = PopUpManager.createPopUp(contextView,MessageWindow, true) as MessageWindow;
newTitleWindow.text = message;
PopUpManager.centerPopUp(newTitleWindow);
[Code]....
There is no nested components displayed when I run my app.
The debugger shows they are created and visible.
To my "amusement" the components are shown when I replace s:TitleWindow with mx:TitleWindow.
I really want to use spark TitleWindow.
This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event

Im creating a microsite, in which the background colour changes depending on which section you are in! I want it so that when i go on one section the current background fades out as the new on faids in!Ive got the fades in's sorted, however is there some sort of script that i can put in that tells the current background to faid out??Also say im in the red section and then want to load a diffrent aspect of the red section! I dont want it to re-load the Red background! Is there some way of achieving that?? My first throught was to use some sort of IF statment, however im not exactly sure how i do this?
View 4 RepliesI am making a web page with about 13 buttons. some are dropdown menu Items.I would like to have a background linked to each of the buttons, such that when I click on a new button the background fades into the new background.
example: I am at my home pag, and the background picture is a tree. you click on my about button, and the background fades into a picture of a book. you click on my contact button and the picture fades to a house. then you click back on the home button and the tree fades back in. If you are at home and you click on the home button the picture should fade into the same picture etc.how to do this without creating each one of the fade transitions manually.

Suppose I have a component and want to change it's focus color at runtime. Here's an example for you (I've excluded any buttons and such to prevent component from losing it's focus, cause in that case it changes it's color perfectly):

What do I want: How to make this focus to be redrawn without magic (I've tried all the methods, starting with "validate", I've tried calling updateDisplayList() on entire application, I've tried to call styleChanged .
I am trying to write the code for making a text input control in flex. As the user enters the value in text input control and then if he removes the typed characters to make the text input blank, then I print error message via StringValidator. But I want the focus to be set on that text input only until the user enters anything. How can I achieve that?
View 2 RepliesI need a few minor changes done to my site such as changing the text on the About page and also changing it so that when you view a picture in any of the galleriess the background is completely black, right now it just fades out the text and thumbnails and is not entirely black.
I have never used Flash before but am pretty good with Photoshop, Illustrator and a little bit of Dreamweaver. Would these changes be difficult for someone who has never used Flash but can pick things up fairly quickly?

The spark panel component for example can be written like this
<Panel title="Skinny">
<child components ... />
<controlBarGroup>
<child control bar components ... />
</controlBarGroup>
[Code]...
The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.
Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?
I created a custom MXML component, TurboContent, that extends the NavigatorContent class:
<s:NavigatorContent xmlns:fx="http://ns.adobe.com/mxml/2009"

In this case, the 'myButton' component never shows up, but all the elements of the base component do (3 buttons and a datagrid).
How can I make the background of the Button component transparent in actionscript (or remove it completely) ?I'd like to show a Button component with only the text label, no background, no border.

View 1 RepliesSo we have a component we have written ourselves that deals with text display and translation between languages, reading translations from a file. Ideally what we would like to do is have this component be compatible with any font we can embed in the main .swf's library. What's the best way to do that?
Currently we are going down the route of having our component have an attribute for the font name, lets say 'Font1'. We drag the component into the .FLA file we want and then add a new font to the library called 'Font1' and set it to the typeface we want. This is proving to be inconsistent and problematic which implies it's not really an ideal way of doing it.
Is there anyway to achieve the feature we want? The key is flexibility, we want to easily support languages (hence the component) but we don't want design to be limited in their font selection. Its not practical to embed a range of fonts in the component for example, as it adds to file size and is restrictive.
The entire box at the top is a Flex application. The box on the left with the list of pinball machines is a VBox. As you can see, if you try to scroll with your mousewheel, it doesnt respond. The reason this is shut off is because I found that if it's turned on, when you scroll up/down, the whole page goes with it. So if you scroll down four or five times, the application goes out of sight.I tried finding a solution to this when I programmed this last year but wasnt able to find any answers.if there's a way to make Flex grab the focus of the mousewheel and not let the browser move as well?

I have a remoteobject within my main.mxml.I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint.When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence.[code]
View 2 RepliesThe project I'm working on requires older libraries that extend mx components (such as TitleWindow and TabNavigator), I can't use what I know about Spark skinning directly. However, since the project is being programmed using the default Spark theme (with my modifications on top) rather than the Halo theme, I apparently don't have access to the styles I need (namely backgroundImage and contentBackgroundImage which apparently require Halo to be active). Simply setting Halo to be the theme will break other things, not the least of which my own theme.
Plans are in the works to replace the older libraries or at least patch them better to Flex 4, but as of right now, I need a way to style/skin these components without modifying them directly. It would be ridiculous to be unable to add a background image to a TitleWindow's content area! I've searched the internet high and low all day and tried countless variations of styles, skins, selectors, and combinations thereof with no luck. How to add a background image to the content of a mx TitleWindow while using the Flex 4.1 sdk?!
In a component 'Group' I drag multiple pictures at one time I need to clean this component, but contains a component BitmapImage and I will not be erased:

I'm making a UI for a component in Flash. I wanted to use Flex and have had no luck getting the onUpdate exernalInterface call to fire properly. I'm referencing the functionality described here: [URL]. First off, I can't embed the SWF in the FLA. It just won't start the Flex SWF. Even using the external swf, it seems that the onUpdate function is either called too early or not at all. Here's what I've tried:
Tying the externalInterfce declaration to the initialize, preinitialize, applicationComplete, and creationComplete events. Sub-classing my application and putting the externalInterface in the constructor. Neither of these options work. When I create a basic AS3 project in Eclipse and put the externalInferface in the constructor, it works as expected.
