Flex newbie question: can MXML be generated on the fly, like HTML is generated by a server? If yes, is it ok to do so or am I missing an important Flex architectural principle.

How to add Column to Adobe flex mx:DataGrid in mxml and/or actionsctpt?

I am attempting to implement a layout in Adobe Flex 4.5 / MXML where I have multiple controls in an HBox that - in total - consume all available horizontal screen estate. Some use a relative with (percentage), some an absolute width (pixels) and one is supposed to consume whatever space is still left, such as:
+----------------------+-----------------------+------+
| 35% | fill parent | 10px |
+----------------------+-----------------------+------+
How would I achieve this in Flex (is there something comparable to Android's
layout_width="fillparent")?
Due to the fact that there are elements that have an absolute width I cannot easily calculate the width of the filler as a percentage a priori (as it varies with the screen width). Setting the filler's width to 100% also does not work as this will shrink the 35% area below 35%. Applying the updateDisplayList suggestion from www.Flextras.com's answer below yields the error "Call to a possibly undefined method updateDisplayList" at the line marked in the source excerpt below:

I am using progressive streaming with VideoDisplay, the HTTP URL provided gets buffered completely even if I have configured it to start playing the video when the buffering reaches 20%, the trace message shows that the playing started(using mozilla /Flashbug+Firebug), but it doesnot show the video till the buffercounter reaches 100% How can I get the video stream to play at the 20% of stream.Code Segment where the check takes place

Does 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 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,

Does anyone know what criterea Flash uses for discovering the Live Preview class for a Component? Background We are attempting to automate the creation of a SWC that contains a component to be used from Flash. We are able to make it visible to flash by modifying the manifest.xml and wiring up the component definitions. However, the component cannot be dragged onto the stage (or library), presumably because it has no form of LivePreview. To give better clarification of where we are coming from, we've noticed the following in SWCs exported from Flash (using swfdump):
fl.livepreview.LivePreviewParent contains the same mod attribute as the visual component in the manifest.xml file fl.livepreview.LivePreviewParent is exported as a symbol The short-named component (ie. no package, referenced in the components definition in the manifest.xml) is exported as a symbol However, I can see no other differences between that and the SWC from Flex. We can obviously use JSFL to perform the task, but we'd rather not install Flash on the build server.
I have some shared code between an Adobe AIR App and an Adobe Flex App.
On one line of this code, the program must behave differently depending on if it is running within the Air runtime, or the Flex runtime.
How can I programmatically detect the difference?

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.

I have a Flex application which references a separate MXML file as a template for a custom component. I create instances of the component dynamically several times in my program, but I need to get a handle that will allow me to modify that instance of the component as desired. I pass specific information to this component on instantiation using bindable public variables in the component's MXML file. I add it to my main program using addChild().
I want to update the component's progressbar as necessary and I want to remove it from the box to which I addChild'd it. What's the easiest/best way to get a variable that will give me predictable access to each component so I can easily manipulate the components as necessary? Some research suggests creationComplete, but I decided it was faster to just ask than to go through lots of different experiments and come up blank.
