I want to create a component with a variable/parameter that is a method it calls when (clicked on for example). In "Flash UI Components.fla" the they do this and I studied the code but cant get it to work. The Push Button one has a click handler, but the way it is actually called in the script is like this:
this.handlerObj[this.clickHandler](this);
That bracket/parenthesis thing is not working.
When I define custom propertie in my MXML component, I also want to define a set of possible values of that property to make Flex Builder show then (possible values of the custom property) when I invoke code completion function.
View 2 RepliesFor my AIR based application I am trying to create a custom component based on canvas which has an image (as shown below).
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="100" cornerRadius="5" borderStyle="solid" borderThickness="2" dropShadowEnabled="true" borderColor="#EDEDE8" dropShadowColor="#dddddd" shadowDistance="5" shadowDirection="center">

As a work around, I am trying to add an creationComplete listener to the canvas in my custom component and used to give titleImage.source = this.path . keep changing the image or when the path of the image fetched using some async call.
I have some simple function in Flex in which I would like to send one of my variables to all the components used in my app... The problem is that there is lots of components in my app, and I'm not sure how to reference to my component's id... Basically, is there an easier way to do this;
private function preloadStuff():void{
// populating of bulkLoader var
var preloaderItemsList:XMLListCollection = new XMLListCollection(preloaderItems.children());
var item:XML;

I am created a dynamically adding a VBox, that contains two images. Into a Custom Component that is derived from UIComponent. The problem is the Vbox that contains the two image is only a really tiny size. I would like the VBox stretch to the size of the two images. This is how I am creating the Vbox....

I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2;
customclass1(parameter1);

I have a component I have built in AS3 that takes a parameter which is likely to change with each instance of the component on stage. ie. the parameter will be different on frame2 to what it was on frame1.
The problem I am having is that flash will not recognise the change of parameter and redraw the component unless I do something like giving it a different instance name or putting it on a new layer. I find this very puzzling as I have the exact same component in AS2 and am not required to perform these actions to get it working.
I have a DataGrid bound to an XMLConnector and XMLDataSet. The XML data loads fine into the components. However, I cannot get the value of the selected index using: my_datagrid.selectedIndex
The call works fine if you use addItem to populate the grid.
Is there an issue being that the datagrid.selectedIndex parameter is bound to the XML components?
Am working on a flash component that is supposed to display some dynamic text which might include HTML formatting. This text is displayed in a label component (AS3), and i would want it to render correctly, like create a line break when <br> is inserted, but it doesn't!
So am wondering what the supported HTML tags in the label component, and in general all other flash components?
I want to call a function from another function's parameter but I don't know how and don't know if it is possible.I've considered this as a solution but it didn't worked.
Code:
function myFunc(target_mc:MovieClip, nX:Number, nY:Number, cFunc:Function) {
target_mc._x += nX;
targen_mc._y += nY;
target_mc.onPress = cFunc;
[code]....
If I set my variables as type MovieClip instead of the type of the class for the MovieClip I am calling them as, will this affect my presentation in any way? Say I have a movieClip Walls with a class definition Walls. Will
var newwall:MovieClip = new Walls(); or
var newwall = new Walls();
be any different than
var newwall:Walls = new Walls();
I was wondering if anyone knew how to create custom components, like a Window for exemple. Flash's help doesn't really help on that, and the subject is pretty new so Google return nothing relevant.
View 1 RepliesI have a custom component written in action script (no UI). I am instantiating this component in an mxml file which is present in a library project. The custom component has a constructor which takes one argument. The library project is used in some other web project from where i pass a variable to this mxml file.[I have linked source of the web project to source of library.].
I have a static variable in my library project which holds the reference of the current object of the project. I need this static variable in order to use properties present in the mxml file. I am unable to use the property sent from the web project in the constructor of the custom component, but able to use the same in some other function present in the custom component.
I have a custom component written in ActionScript. It has constructor which is expecting some arguments.
I want to include that custom component in mxml like this,
Main.mxml
...
<custom:CustomActionScriptComponent/> // Error line ..

But, it shows me an error saying
Error 1136: Incorrect number of arguments. Expected 1.
How to pass parameter in MXML file, to that custom ActionScript component?
In class Main I am instantiating a custom class NavLabel that creates a textField. With in NavLabel I dispatch a custom event CustomEventWithParams on a reference to class Main that passes the parameter theLabelWidth along with it. from with in class Main i can trace the theLabelWidth for each of the instantiated NavLabel objects. I want to hold those values in an array labelWidthArray and then use them to position the NavLabel objects. how can I do this?

I have a custom function with parameter. I'm trying to pass the parameter to the gotoAndPlay as follows. This is where the function is called...
Code:
myButton_btn.onPress = function() {
myFunction("Apply");
}
This is the function...
Code:
myFunction = function (fLabel) {
trace(fLabel);
gotoAndPlay(fLabel);
}
Basically "Apply" is a frame label that I'm trying to send the playhead to. The fLabel paramater traces out properly, but the gotoAndPlay doesn't send the playhead to the appropriate frame label. It sends it to 4 frames before the end. It's really weird. Even if I add frames to the timeline, it still sends it to 4 before the end. I can get it to work perfectly in a "new" flash document, but not in my existing document.
After browsing the internet for a while I found everyone shows you how to make a custom preloader with your own graphics which is all fine and good but what about the people who just want to use the components and be done with it? I know I would have to use the UILoader and another

A few days ago I decided I wanted to make my own drag&drop flash components, with inspectable properties. Since the documentation for flash components is so limited, I followed the workflow of some blogs I found around the web (mostly about CS3 components). In the end I managed to create a component that has a Live View, that gets a visual update whenever you change the properties (width, height, color..) ....in CS4 !
The problem in CS5 is that when I drag my component on the stage, the timeline of this movieclip starts playing in a loop. As you may or may not know, Components have 1 "Avatar" frame, and 1 "Assets" frame. So this looks kinda weird when that timeline plays.
There is always the possibility that I made a mistake, but when I download the source files from the blog post on the page http://active.tutsplus.com/tutorials/actionscript/creating-flash-compo nents-for-distribution/comment-page-1/#comment-33865
the same thing happens.
When I then save my CS5 FLA as a CS4 FLA and try to use the downloaded component and my own, both of them work fine in CS4. So I think this might be a bug in CS5.? Which is pretty bad because I wanted to use these components in iphone development using the CS5 packager...I read somewhere that we actually use the UIComponent because it has no timeline, so I don't see how it's possible that it plays.
I uploaded my source files to [URL]
I'm trapping keyboard events on the stage and dispatching custom events through a framework (Mate, though I don't know that this is an important issue), but I'm pretty confused by the scope. The structure is:application (traps keyboard events and dispatches custom event mainPanel (receives dispatched events but mainCalendar (a child element) is null on debugging. Obviously if I try to call a public method on mainCalendar it errors out, even though it's a child of mainPanel. However, mainCalendar is NOT null IF I use FlexGlobals.topLevelApplication.mainPanel.mainCalendar. Outerdocument and parentDocument do not expose mainCalendar either, BTW mainCalendar (a custom component inside mainPanel with public methods. Creation policy is 'all' and it's visible and exists long before I trap any keystrokes at the top level)Could someone take a minute and explain why the mainCalendar is out of scope when mainPanel receives a custom event, even though mainCalendar is a child of mainPanel. Is there a better way to manage the events so I don't have to always address the component via the topLevelApplication?

View 3 RepliesWe are building an interface for a game. The interface has a tabbed menu at the bottom of the screen, with each tab displaying different aspects of an object (called a node). When you click on one of these parts, it becomes the focus, and we download it's details in XML, including all it's sub-nodes and parent nodes and then update the tab display accordingly, or at least that's what we'd like to happen.
What we have:
MainInterface.mxml

public var currentNode:Node = new Node();

We tried adding an event listener for "selectNode" to the dashBoard:SkinnableContainer you see see above, but it didn't seem to want to take. We suspect this is because dashBoard is from a spark component and the dispatcher for "selectNode" is on of our own custom components, but we weren't sure... in any case that's what the code assist seemed to indicate as we had to write it in by hand. We're not sure how to pick up the Events in FlashBuilder 4's debugger, so we're having trouble working out where it's going wrong.
Basically, when someone clicks on the label of a child or parent node (that is displayed by the itemRenderer), we want a URLRequest sent to our website, with the url specific to the node clicked on. We then want a URLLoader listening for the return which will update public variable 'currentNode' when xmlDownloaded is called by the loader. If you could clarify how the click event should be dispatched, what should be listening for it then sending the URLRequest and where the URLLoader that is listening for the xml data to return should be that would solve our problems.

View 1 RepliesI want to develop custom components (that show up in the Components panel) which a Flash designer can drag onto the stage and use the Component Inspector to customize it to their liking (inspectable parameters, I believe they are called). I'd also ideally like to implement a Live Preview so they can see their adjustments live on the design stage.
Does anyone know a good resource for learning the correct way to do this? I've found one that used to work in CS3 but now that I am on CS5 it isn't happening for me: [URL]. There's also the "official" Adobe blog post, I think the previously mentioned article gives it an appropriate shout-out for being "long and cumbersome". It seems that this should be a pretty popular technique.
Is there a way to write a custom event that gets triggered when the user clicks outside of that custom component instance? Basically anywhere else in the main flex app.

Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?
