I have been using Flex Builder for a while now, infact since i started coding in AS3 Projects.One of the fundamental issues i have from experience of trying flex, is i dont see how MXML tags and AS3 is related.Can someone try to explain to me from an Actionscript perspective?If i create a PixelBackgroud.as class which extends sprite and draws a random pattern, then how can flex use that class? Does it automatically become <PixelBackground /> ?
How do I relate a variable to an object on the stage? I want to have a mouse over and a mouse out effect on a button yet when I use the code below I get the error:
ReferenceError: Error #1065: Variable button is not defined.
obviously the object on the stage is called 'button' but I didnt think I had to define objects as variables? I thought the below code was correct?[code]....
Like I understand that if you're assigning something within a class it would have to involve what's extended to this class.So if a class extends MovieClip, would you only Set properties that involve the MovieClip object?Adversely, with Getter functions you could be retrieving anything from XML to volume. So that can't have anything to do with what that class is extending towards right?Is that how the extends relationship works with Get (return) and Set (value) functions?
I want to perform keyboard equivalents instead of using my moouse to navigate through my project. I want to use left to go back a frame, right to next frame and up for home and down for exit. I've put here my code for the button instance (NEXT15). How can i capture key presses and relate them to these buttons.
Im trying to get the X, Y of a Movie clip (well call it "target_mc").its inside of a parent MC (well call it...."parent_mc")but im trying to get the X,Y as they relate to the main stage(_root).so far the two methods ive used are
it seemed like the first method(the one in the code block) places it at the starting position of the MC i need the location of, but to further complicate it the parent_mc is a rotating clip(Ive got code to make it follow the mouse).how i can place this in a location that is changing whenever the mouse moves
I'm a bit rusty of my trig, so I'm not sure the best way to do this ... I need to position 2 movie clips on the stage that relate to each other they can't be nested ,the registation points are in the center, assume "clip B" is 50 px to the left of "Clip A" as pictured in the diagram to the left , when "clip A" is rotated, I need clip B to follow ( still 50px ) away but with new _x and _y relative to the rotation of "clip A" as in the diagram right.
I wondered if anyone can provide any information on how flash events relate to the DOM event model.My issue is this:body > div > object.The div has a mousedown event which calls 'preventDefault' on the event object.This shouldn't bear any relation to a click event within the objects swf however in IE9 it prevents the swfs mousedown event from firing..I'm struggling to understand how swf events fit in with DOM (presumably they continue to bubble up from the object element?) and why a click event on a div would affect a childs swf click.
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?
I 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:
I am trying to override a Button class, i have a few properties which i wish directly initialise with the mxml description of the component, like :[code]which function is triggered ( in order to override it ) when all properties with mxml description is fully initialised with their values ?
Alright, so I've been struggling with this one since last night. When I create a new object (a new unit), and draw it to the screen (Flash does all the work there), the point at which it's first placed is considered its origin. That is, getX and getY will return the distance from that point... Why is that? Or how can I stop this?
What I'd like to do: create an MXML component with some children, then extend it via MXML to create a new component with more children, without losing the original set.In other words
create a component bc.mxml <?xml version="1.0" encoding="utf-8"?> <s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009"
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 3 mxml components. In Component 1, I let the users fill in some data. In Component 3 I want to use the data, but I can't find a way to make it work.
suppose i have 3 buttons(for example say, productin, marketing, sales ) on my main.mxml..once i click on one button it should take me to abc.mxml page with production data, once again if i click on second button it should take me to the same abc.mxml but with marketing data. same as for 3rd button also, how can i achieve this ?
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?
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,
A Flex components values are initlized by init methord. In an application flow, How to refresh a mxml component data value ; as init is callled at the start up it self only.
eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )
I have developed a small chat application in flex. I have the mxml and some as (actionscript) files. I have the result returned from a php page in the mxml. I have this value in the script section of mxmlmyName = event.result.login;I have assigned this value to;<mx:Text id="uname" text="descr" valueCommit="myName" visible="false" />Now I need to get the value of this, that is, I need to get the value of "myName" in one f my as files. I could get the name and id of Text, but what do I need to do to get the value of Text in as code...In javascript I could do like getElementById(' ').value...How could I get the value here.
I'm trying to compile gui/flex/songs.mxml in the fourth edition of Bruce Eckel's Thinking in Java book and am getting a compilation error with Flex 3.4.
Here is a simplified version of the example that gives the same error:
I've been having trouble exporting Adobe Flex using Adobe Air. I can't find the runnable application Air, and so when I export something to be opened in air it can't be opened. I'm on a Mac Powerbook G4 running OS 10.5.8.
