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
{
[code]......
I have three lists and a button. Depending up on the selected items in first two list and after clicking the button I have to display the items in details list.
-In first list I am displaying names of employees
-In second list displaying managers names
-Then if I select one employee name and one managers name then after clicking button corresponding employee and managers details should be displayed in the third list.
The problem is with initializing the details list and dynamically changing it.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
I've never extended a component class in AS2, and I'm having problems with it now.
Here's my class file:
Actionscript Code:
import mx.video.FLVPlayback;import mx.video.*;class AkamaiFLVPlayback extends FLVPlayback{
public function AkamaiFLVPlayback(){
super()}}
Here's how I'm trying to instantiate it from the FLA:
Actionscript Code:
import AkamaiFLVPlaybackvar g = new AkamaiFLVPlayback()this.attachMovie(g,myVid,1)g.contentPath = "[URL]"
Now this does not work at all. I can see that the super class FLVPlayback is creating variables, but it's not loading to the stage or initializing.
I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
I need to access topBox's grandchildren and determine whether they're buttons or not. This function belowgrabs topBox's immediate children which are the HBoxes. How do I go one level lower to topBox's grandchildren? Or is the only way to do this is to run this function on each HBox?
for (var i : int =0; i<topBox.numChildren; i++){
var child : DisplayObject = topBox.getChildAt(i);
var myButton:UIComponent = child as UIComponent;

I 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.

I am injecting two properties (question and answer) to the FaqItem component from an auxiliar file (using BabelFX) that depends on the id of the FaqItem, but it is only working when I choose the second option. If I use the first option, I get a child but with the text in question and answer fields is empty. I need to use the first option.
Are there any way to declare a child component in mxml which is private/protected or even static? Sure we can do this inside a script tag, but are there any other way?
View 2 RepliesHow can I add an MXML component as a child of the main application using ActionScript. It's not possible to instatiate it, is it? Assuming that behind every mxml file stands an actionscrpt3 class, I tried to import it but id didn't show up.
View 1 RepliesI have a public variable set within fx:Script tags in a parent component that I'd like to access directly from a child component. How can I do this? I don't want to pass the variable to the child component (I know how to do this and am currently using this approach). Following is a simplified version of the mxml:
Note: SimpleComp is an HBox with a couple of lists.
<mx:Accordion>
<comp:SimpleComp/>

Here is an example of a custom component. It is just a box with a title label and a close image (X):

When using the component in an MXML document, I would like to have the "(HEADING TEXT)" replaced with a parameter (should be easy) as well as the "(INSTANCE MXML)" with several labels, text inputs, check boxes, etc. (maybe harder). I have found this script-based method, but I would like a cleaner compile-time solution if one exists.
I have many buttons in HBox. Instead of disabling each button, I've disabled HBox. But I am able to click buttons even though the HBox is disabled. Disabling parent component will not make difference on its child? it shows like disabled but mouse events will generate.

View 1 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

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 need a time chooser for a flex app, and as far as I can tell there is no UI component to manipulate Date objects at a resolution finer than per-day (the DateChooser component).What's a good time chooser for Flex? I strongly prefer a Free as in Libre and/or Free as in Beer component.
View 5 RepliesI am having an issue with an actionscript event that I am firing every time a flex component resizes. In the event, I am altering the height of the flash object within its html wrapper via an external javascript function. This in turn causes the component to resize and the event to loop in upon itself and continually add height to the component.

I've a custom component where I do some graphics (e.g draw a line) and dynamically add a subcomponent (e.g a label) to it.
If I base the component off Group (which is recommended as per docs since its a spark component) then when I dynamically add a label the graphics part disappears.
However if I base it off Canvas this doesn't happen.
Why is that the case?
Here is the code.
MyComponent.as
public class MyComponent extends Group
{
public var x1:int;

View 1 RepliesI am creating a flash object that does some heavy image lifting. What I am looking to do is load many flash objects onto the same page to take an image, modify it, and display it within the flash object.The problem I am running into is that when I try to add 100 flex objects to the page, the browser freezes as it tries to re-load/initialize each instance.Once they are all loaded, the processing of the images goes by quick.Does anyone know how to duplicate the flash piece without having to reload everything?
View 2 RepliesI have a repeater that populates a component, called 'project'. The project components are given an ID of 'wholeProject'. In all of my functions up until now, I was able to determine how many project components were made by doing the following:
wholeProject.length;
I used this in for loops, for each loops, and for changing the item settings within a project, i.e. something like this:
wholeProject[i].studentName = "Billy Bob";
However, I'm creating a new function that does not seem to like this wholeProject.length reference. I'm using it within the same level as all the others (i.e. the parent level). So far, my function is simply this:
public function getStudentYears():void
{
Alert.show(String(wholeProject.length));
}
when the application loads, the alert message simply does not appear. If I change the alert to something like this:
Alert.show("This is just a test.");
it works just fine. But for some reason, the wholeProject.length doesn't work in this function whereas it does in all my other ones.
I 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)?
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.
