I want to add a component into a Viewstack dynamically in flex4. Like code below
[Code]....
But the code in comment doesn't play the effect. How can I implement it? Does the canvas have any hideffect or showeffect to Bind
I have a viewstack with 3 items in it. Now my problem is that I want all these components to be of the same size. Its simply enough to do this manually but is there any other way of setting the size for all the components at once?
View 2 RepliesI have a viewstack with two tabs.In one of them there is a data grid shows a list of notes. The other one is includes a form that can edit notes or crates new note. I want the user to be able to add new note or edit existing note when clicks an item in data grid. I mean when user clicks an item the viewstack must become editor.
View 1 RepliesI'm very sleepy right now, so this is just an example of what I want (obviously this code is wrong):

I have a viewstack in my main application
public var currentStep:int;
<mx:ViewStack id="step" selectedIndex="{currentStep}">
<comp:Choosecar id="choosecar" />
<comp:Configcar id="configcar" />
</mx>
I'm using a drag and drop inside to choosecar component, so I want to change the 'currentstep' - which is a variable of the main application - with +1 so the viewstack changes to the second component 'configcar'. The only solution I found is calling a component from the main application, I need it the other way around but I can't find it.
I'm having a viewstack with a few components. Those components have to execute a function with parameters coming from other components. Therefore the other component may not me loaded directly. Is there any way to load a component via AS3 with a function?
View 2 RepliesI want to dynamically add component in Container like Canvas(TileList constraints each child has the same size, GridList is poor in performance), for example
[Code]...
when I click the button, I hope add a component(whatever the component is, and maybe each component has different size), and if the total width of all added child is greater than myHolder, I hope the new child can begin in new line, and stretch the height of myHolder at the same time.(layout with custom code is better)
I'm trying to display a custom component i made inside a panel but when it renders the content is displayed outside of the panel box and there's no scrollbar.a panelan instance of myComponent inside the panela button that calls a method on myComponent that adds some controls into itWhen i run the application and press the button the following is displayed:See that the controls added dynamically in myComponent get over the panel's bottom line instead of showing only the visible part of the component and a scrollbar.
View 1 RepliesI need a List that resizes to exactly fit its content, unless that height exceeds its (dynamically sized) parent container. My requirements are as follows:
The component extends List, or at least acts similarly. variableRowHeight and wordWrap both equal to true. The height of the list cannot be less than minHeight (roughly 32px for scrollbar arrows). The height of the list cannot be greater than the height of the parent container .
Note that the parent container can be resized dynamically.
The height of the list should be updated as the size of both the contents and parent container changes.
Live updating would be preferable but not necessary.
There should be no scrollbars if the content height is less than the parent container height (sounds obvious, but I've had trouble with this too).
The trouble is that with variableRowHeight and wordWrap, it's very hard to know the size of the content at any given time. If the parent container's width is reduced, a line wrap may occur in the list which will change the height of the content. I know I can measure the height of the list content using measureHeightOfItems() + viewMetrics.top + viewMetrics.bottom, but when should I calculate that? What events should I listen for? And the thing I've had the most trouble with - when should I calculate it to set the size initially (i.e. just as the content has finished populating)?
In a current Flex project, i have an issue where a certain child component must be initialized and ready when the user clicks a button. the button is a mouseClick Event.
//mouseClick Event
protected function tableSearch_searchClickHandler(event:MouseEvent):void
{

I have been stuck on this for far too long. I think it's simple so I must be misunderstanding something. I want these to display across the full width of my flash app. When I shrink the width of the flash player I want a scrollbar to appear. At the moment no scroll bar is appearing.

How can I dynamically change components text size in item renderer? Here is my CustomItemRenderer.mxml:
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="[URL]" xmlns:s="library://ns.adobe.com/flex/spark">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->

I have problem with casting custom event currentTarget to component. When I'm trying to removeElement from its parent container i get error. What's the deal?
TypeError: Error #1034: Type Coercion failed: cannot convert mx.events::FlexEvent@8811c41 to com.modultek.pis.itemmachine.search.events.SortEvent.
private function sortSelection_removeHandler(event:SortEvent):void

this.removeElement(sortSelection);
}
I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob.
i.e.
private function prePrint():void
{
var printSelection:Box = new Box();
[Code]....
I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go.
i.e.
printSelection.includeInLayout = false;
addChild(printSelection);
I have a view component called viewBase where I defined a advanced datagrid with few item renderers for datagrid columns. Now I have a requirement where I need to use the same view viewBase component, but not required to use any item renderers.
how to override the itemrenderers which are declared in a view component?
I have a custom component which contains many promptingTextInput controls. When i click a button, I want the text field of all the promptingTextInputs to become blank.

I realized that if I do addChild, I can't really see the dynamically added component, since flex did not reserve space for my List to display. So I do parentDocument.addChild, and then it appears no problem. My question is since it's being added in the parentDocument, so it is suppose to be a component belong to parentDocument, so is that component still be able to call this handleMouseDown? From my experience, it's still able to, but which doesn't make sense to me. Can someone explain a little about why it can still work, or any better approach other than parentDocument.addChild
I've been searching for the last couple days but can't seem to find a basic example of what I'm looking for. I'm developing a Flex 4.5 app and in it I have a viewstack of 2 components that use some of the same services. Currently the only way I can get the app to correctly use the web services is by defining 2 different web services that use the same PHP web service file. For example: I have an app, and within it I have a viewstack with tab navigation of 2 components: #1) retrieve a list of all Salary Employees, and #2) retrieve a list of all Contractors. Currently to get it working I am defining a UsersTableEmployees webservice within component #1 and a UsersTableContractors webservice within component #2, but they both point to the same PHP class, and only differ in the arugment value I pass to them. Ie, getUsers("employee") and getUsers ("contractors"). Of course this is not best practice.
Searching StackOverflow and Google gives me many results about ColdFusion and MVC (example What's the best way to share data between components in Flex?), but I'm still confused. Can anyone here point me to a basic example (even sample MVC) and source code of an app that uses Zend AMF and allows different components to call common web services?
I have a situation where I am loading an SWF (using URL as source) using the SWFLoader component in Flex 4, and now I need to implement Pause/Play and Stop functionality.
View 1 RepliesI'm using a viewStack which have is property resizeToContent set to true. When I'm selecting a child higher than the viewStack, it's correctly resized, but when I'm selecting another child which is smaller, the viewStack isn't resized! What I want is that my viewStack get the height of the selectedChild each time.
though, the Adobe doc say :
If true, the ViewStack container automatically resizes to the size of its current child.
I've got a Flex 3 project.Does deep linking only work on viewStacks? (My project doesn't have any viewStacks). I'd like to use deeplinking based on what was selected in a comboBox. I'd like the user to be able to bookmark or use the back button based on what was selected in the comboBox.The comboBox selection determines which data is pulled from the database.Is this possible? I set-up deeplinking in another project, but it had viewStacks. And all of the deep linking examples that I've seen use viewStacks.

I have as good as finished a new project I'm working on now for a while, and I have this small problem coming up at the fine tuning.The area of concern is so I believe the ViewStack I'm using, but I'm not sure so here the details.I have several check boxes (4), and only one at all times can be selected to show off associated Radio Buttons as a Group of (6). No RBtn pre selected.With the selection of a check box I also make visible a new Radio Button Group of (4). No RBtn pre selected here either.Now if I select one of the RBtn (6 - each has a different Paper size measurement showing) then I can view through a external Xml data file details as Size, basePrice and the totalPrice which is in this case the same as the basePrice!
This totalPrice is located on the first Canvas/Label in the VStack!Selecting any of the first three (3) of the second RBtn Group (4) No RBtn pre selected either! - it will show me a Paper type description, and by selecting the fourth RBtn it will show me as well a field with the extra costs for a Canvas type, and it should select the second Canvas of the VStack with the totalPrice which is basePrice plus the extrasCost Canvas Price.Now the problem is that my second VStack Canvas/Label = totalPrice (basePrice +extraCost) is not showing up immediately! (It just shows blank canceling the basePrice out), and only if I select another of the six (6) RBtn! then it is showing the second vStack with the totalPrice (basePrice +extraCost). From here on everything works perfectly!I think that I have to mention that my RBtn Group are working in a function If / Else / If /Else configuration where both the Labels on both VStack Canvases are called up at the same time. So therefore both Labels should have data available which than should be viewed when the VStack changes?
