View 1 RepliesActionScript 3.0 :: Flex Components Without MXML?
Nov 1, 2010I'm working on an AIR project in Flash Builder 4. My question has apparently been asked a lot (according to Google), but I haven't found a satisfactory answer so I'll be very detailed in what I'm looking for:Is there any way to create an AIR project in pure ActionScript that:Is truly object-oriented (i.e. the entry point is an ActionScript class with instance variables and methods)?Can instantiate mx and spark controls without MXML?I was able to accomplish #2 in fairly different ways by following these two sets of instructions (with only a tiny bit of initial MXML):
[URL]
However, neither of those allows me to accomplish #1. If I declare a private member variable outside the entry point function, I get an error from the compiler that the keyword 'private' can only be used in a class.If you like MXML, feel free to post your viewpoint as well. My reservations revolve mostly around these perceived notions:The learning curve of MXML seems steep.The time it will take to become good at MXML will not be worth the investment since its main purpose is to ease GUI development (which I'm already good at anyway).Like I said previously, I don't want to be an "XML programmer". I'd like to maintain the power and flexibility of OOP.
Flex :: Sharing Variables Between MXML Components
May 29, 2010I have several mxml components in an app, all of which need the same variable called genericX. I've included that variable in the main mxml and made it public

View 2 RepliesActionscript 3 :: Creating Components By MXML Or By SCRIPT/FLEX?
Mar 9, 2012im trying to figure out what is better for run-time, creating components in MXML or by SCRIPT?. I built an app that recieves data from a server without knowing how much data exactly. In worst case scenerio , ill need 10 LABELS and 2 DATAGROUPS.But i usually need something like 3 LABELS and 1 datagroup. what is better? creating all components in advance and than not include in layout the ones i dont need, or make some checks and then create only the components i need by script? I made some tests , but it wasnt really decisive, run-time was pretty much simillar.Im guessing it must be stated somewhere what is better. Does anyone have an answer for me?

Actionscript :: Flex - Setting ScaleX / Y In Mxml Effect The Components Size
Jan 1, 2010I'm playing around with the scaleX/Y in the canvas tag and have noticed some strange behaviour. When I set scale in in mxml the width and height of the canvas are adjusted accordingly. For example if I have a canvas like this: <mx:Canvas width="1000" height="1000" scaleX="0.1" scaleY="0.1" />
The canvas now appears on screen to have a width and height of 100 and if inside my creationComplete callback I check the width and height property they are indeed 100. But if I do exactly the same thing except I set the scaleX/Y property from actionscript the canvas on screen appears to have a width and height of 100 as expected, but when I check the width and height property of the canvas they are still at the previous values of 1000.

View 1 RepliesFlex :: Create Skinnable Components In MXML Using Spark Component Architecture?
Oct 14, 2010There are lots of examples of how to create skinnable components in AS3 using the new Spark component architecture, however I've yet to find any such examples using MXML.What I'm mainly referring to is defining the skin parts and skin states. It seems as though the SkinPart metadata is supposed to be associated with properties and as such can't be used in MXML, is this correct?

View 3 RepliesFlex :: Variable Accessible For All .mxml Files
Oct 4, 2011Im using Oracle, BlazeDS, Java & Flex. I have an ArrayCollection containing data from a small database table. This table won't be the subject of much change. I want to use this ArrayCollection accross different mxml files to fill e.g. ComboBoxes etc. The reason for asking, is that doing a database call for each time a fill a ComboBox etc is slow and seems unnecessary. I tried doing this once in the "main" .mxml file, but then the variable wasn't accessible where i needed it. What is the best approach for accomplishing this task? What is the best way of making a variable accesible across .mxml files?

Oct 27, 2009I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call.

Flash - Flex Compiler Appears To Misinterpret .as Files As MXML?
Nov 21, 2011After changing the Flex SDK to 3.6 (from 4.5.1) so as to target Flash player 9.0.124, the project no longer compiles, producing spurious errors such as XML does not have matching begin and end tags leading me to believe that the compilation process is 'borked'.
This is a pure AS project, and so should have no dependency on the Flex SDK, howver, it seeems to be inextricably linked to the Flex 4.x SDK and Flash Player 10+. I have tried swf-version and -target-player-version in the compiler arguments, but there is still something I am missing to get this to compile for Flash player 9.
Flex :: Use Flash Builder To Run Multiple Mxml Files In One Project?
Mar 1, 2012I imported an .fxp project into a Flash Builder and then observed there are 5 .mxml files in the src/(default package) directory. Silly question -- how to run each of these five files?
Since I've named the project differently than any of the .mxml files, whenever I try to run something it uses the default (empty) .mxml file named after the project. Deleting that empty mxml file didn't help anything. I also tried to clean the project, but nothing changes (although I see the directories refresh with the same contents). There are no html files in the bin-debug directory.
There must be some simple way to run those .mxml files that I'm missing.
Flex - Compile Multple Independent Mxml Files At One Time?
Jun 11, 2009Our application has over 15 different top-level mxml files to create individual controls that are used in our pages. We are using Ant to do our automated builds, and are calling the mxmlc task for each mxml file separately (See question 78230 similar example). Running the compiler separately for each mxml file, however, is already adding up to a considerable amount of time. Our build time is approaching 10 minutes, 5 minutes for compiling our flex apps, and 5 minutes for compiling hundreads of java classes, building jars, installer etc. Each flex compile run is reasonably quick (15-20 seconds), but they add up.
Is there a way to compile all of them with one call to mxmlc?

Actionscript 3 :: Access Non-visible Flex Components?
Oct 3, 2011I'm building a flex 4.5 app that has a custom component extending SkinnableContainer. This custom component is basically a kind of collapsible panel. When you open it you see all the controls in the contentGroup, when you close they go away and you are left with the title. This is done in the skin by having the contentGroup included only in the open state.
I have a bunch of these containers in the app, some open by default and some closed. So in mxml the structure looks like:
<ui:MyCustomContainer open="false" label="bla">
<s:HGroup>
<s:Button />
<ui:AnotherComponent />
[Code].....
Note that if you hit the click me button before opening the second container we are unable to get the value from the control in the initially collapsed group. Opening the group once allows access to the value. Collapsing the group is still ok. It's the first time that's the problem. I have added creationPolicy to the container and itemCreationPolicy to the content group in the skin but no luck!
