I don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE, but it's reporting its own state changes.
View 2 RepliesFor my custom components, when they go from enabled to disabled or disabled to enabled, I want to trigger a custom event. I can't find any related events in the livedocs.
View 2 RepliesI currently use: Flexglobals.toplevelapplication.component1.compnent2.currentState = 'something';is there a better way of doing do? Can I bind the state of a components to variable in my model?

View 1 RepliesI'm trying to create a custom component which is being fed with XML data coming from the server.My problem is that the CollectionEvent listener doesn't get fired and thus labels not updated -Games.mxml (my custom component with listener):[code]
View 2 RepliesI have an event, which I have dispatched in my main.mxml:
var evt:UserEvent = new UserEvent(UserEvent.USERINFORMATION);
evt.userVO = storeObject;
this.dispatchEvent(evt);
I can listen for it while in my navigation.mxml file, by using
this.parentApplication.addEventListener(UserEvent.USERINFORMATION, onInfo);
But in other component, I can not listen for it, even trying the same as I did in navigation.mxml.
tracing it back gives me an undefined.
the second component is in a viewstack in navigation.
In short: I need an event listener in a custom component so all its instances (without editing them) react at the same time, fired by a dispatched event in its parent container. In detail: I have a custom component with Tab navigator. (The tabs are intended to show different preferences for different Languages.) I have a button bar with buttons for all the languages. There are a lot of instances of the custom component.
I want to click in a button of the languages bar and get ALL the instances switched to the same tab (the custom component contains the logic to change the tab). I can do it by adding the event listener for EACH INSTANCE of the custom component, so it calls an internal function that changes the tab. But it seems to be very coupled, isn't it? I wonder if it can be done in the master CLASS of the component, so it listen for events in its parent container, whichever it is. In my mind this code shoud work, but it doesn't (obviously ill'use a custom event to pass the new language value): this.parent.addEventListener("lang_change", this.change_tab); This way I can just drop an instance of the component, and see it working for itself.
I have a piece of software I'm working on that is using a viewstack with 3 canvases. With the change event I need to look for index 2 which is the last canvas when it changes to this canvas I need it to grab data from inputs from the previous two canvases.Within the viewstack events I've assigned the function change() to the event childIndexChange.
Here is the method:

I have flexlib WindowShade component in repeater in my Flex + AIR application.
<mx:XML id="mainMenuXML"><items>
<item value="abc" />
<item value="xyz" />
<item value="lmn" />
</items></mx:XML>
Now in button1 click handler I am appending child in XML(mainMenuXML) resulting adding one more windowshade instance. But the problem is it opens all the windowshade instances. I need to maintain the opened states after adding a new windowshade instance.
For example:
Initially I get 3 windoshades with labels: abc, xyz, lmn all opened.
Now I close the xyz windowshade instance(by clicking on the header)
Now I click on button which appends child in mainMenuXML and also add a windowshade instance with some label "pqr". But now I see all the windowshade instances opened.
But it should be like abc, lmn, pqr should be opened & xyz closed(property opened="false").
How to maintain the opened true/false state of windowshade instances. I tried to add a property in dataprovider Bindable to opened property of windhowshade but didn't worked for me.

I have a button with a click event of "currentState='someState'". Is there a way to tell component to do some function like for example "Function()" when the state changes to "someState"? So execute a function when the state is changed.

You can see my custom InfoWindowTabbedComponent at the end of the post As you can see, right now I have 2 functions that open url`s.
What I`m trying to do is to change this:

I am learning Flex and trying to make a simple RPG to practice. I am using view states to change between screens. right now I have a HomeView.mxml which displays my character information, InventoryView.mxml which shows my inventory items, and EquipmentView.mxml which shows the equipped items. They each have their respective view states.
in my main mxml file, i create a global variable for the character and an ArrayCollection of items in the game. it creates 2 labels in mxml for Inventory and Equipment and when i click on the label it calls a click handler which sets currentState="EquipmentView" or "InventoryView" This works and the state changes and the respective views are shown properly. My problem is in my EquipmentView state. When i enter the state the first time, it has a creationComplete function which displays images for my equipment and sets a click handler. when i click the item, it "unequips" it and removes it from the equipment list and removes the image. this also works fine, but when I go to my inventory view and "equip" an item and return to the EquipmentView, the image does not show. I have a label which counts the length of my equipmentList variable and that is accurate when i switch views, but i cant get the image to display again. Is there a way to call my displayEquippedItems() function (which is originally called on creationComplete) when the view is changed?

I've found a very annoying problem with the itemRenderers in a DataGroup in flex 4, when I mouseout of the itemRenderer is returns to its default state. Here's an example:

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

When the user clicks on the button the VGroup is collapsed as expected, but then if a user moves their mouse out of the item renderer it then collapses, i.e. returns to its default state.
I have three columns and the default visible state of last column is false.My problem is how can I change the visible state of the certain cell while the mouse over any part of the row
------------------------------------------------
| column1 | column2 | column3 (invisible) | row1
| column1 | column2 | column3 (invisible) | row2
------------------------------------------------
how can I show the cell(row1,column3) while the mouse over any column of row1.
I would like the native Flex checkBox to change state only, when the box is clicked. If user clicks the label the state shouldn't change.
The click event cannot be muted as it is utilized in parenting components.
how to obtain such functionality? How to detect, that user has clicked the label?

View 1 RepliesI want to use Adobe mxml to create a swf. However, the mxml gets compiled to swf itself and is not available after creating the swf. I want to add states with UI components without compiling it every-time.
View 1 RepliesI have a component with 2 states and I have added transitions for switching between the states, where 2 Move affects are applied to 2 different objects. This all works fine, however, after the transition from the first state to the second has completed the second state doesn not render correctly. It contains a TextInput control which is not visible, and a Button with a custom skin that is only sometimes visible and vanishes if you click on it. I have tried called invalidateDisplayList() and validateNow() after loading the second state but that has done nothing. I also have a VBox with a cornerRadius property set, strangely this does not seem to apply anymore and the corners are square, where they displayed correctly before I added the transition in.Here is the code for my states and their transitions:
<!-- different states of this component -->
<mx:states>
<s:State name="useForFree"[code].....
where the variables being set as masks are UIComponent instances where I have used their graphics property to draw a rectangle.
It's my understanding that view states can be useful when switching the layout of design elements. Such as, a loading page as one state and the main application design in another state. Is this the correct use of them? Additionally, I have a label in State1 and I cannot figure out how to access that label via actionscript. labelID.text = "New Text"; is not working.

I want to fade all the elements of the next state when transitioning from any state.I tried different things but I can't get it to work. And I don't want to manually add transitions for every state.
Something like:
