View 4 RepliesI'm used to building applications using pure AS3. I always pass dependencies into the constructor of classes I make, but this method seems to not work out well for Flex MXML views. It seems like I should define setters on the MXML class, which map to attributes in the tag/class instantiation. But using this method I cannot specify which properties are required and in what order I expect them etc. What is the preferred method to give a Flex view it's dependencies?
View 3 RepliesDoes MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?
View 3 RepliesI am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:
<?xml version="1.0" encoding="utf-8"?>

i have defined some functions in a component mxml file let us say addbutton() now i want to call this function in main mxml file.
View 2 RepliesI currently have a basic application where we have multiple buttons, which have functions activated by "click" event listeners on those buttons. The issue is that each button does more or less the same function; just the data that is loaded for each button is different. How do I make it so I'm able to recycle the same function? In Javascript or AS3 something along these lines would be done...
<s:Button id="btn_1" x="378" y="601" label="Button 1" click="photoSwap(event,"image1.jpg")"/>
<s:Button id="btn_2" x="350" y="601" label="Button 2"

But that's obviously not how it works. I've tried trouble shooting the issue but haven't been able to find anything. It works when I have each button having its own function, but that seems really silly and shouldn't need to be done.

private var _dp:ArrayCollection = new ArrayCollection([

View 2 RepliesI'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?
This is a project I'm working on for a simple demo tutorial application in Flex. I am using mxml pages. You can see to the left that I will have my main application and then other mxml files (In the Examples Package) as the examples that will be loaded into the main application mxml. How can I dynamically pull the value from the object in the list to load the child mxml file into the container that I have further down in the application?

I would like to include an MXML file in my MXML file in the same way you can include an external file in AS3 using the include directive. Using the include directive brings the code from the external file into the original file at compile time placing it in the same scope. For example,
Application.mxml:
<Application>
<source="external.mxml"/>

I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.
