Css :: Reference A Nested Component In Flex 3?
Mar 5, 2010Using CSS, how would I reference the Button component? FWIW, I'm using Flex 3.x SDK.
<mx:HBox id="myHBox" styleName="myHBox">
<mx:Button label="Test"/>

I have several nested VBoxes in flex, and I'm aiming for one of them to get scrollbars if the total content is larger than the window height. However, when I grow the container, it doesn't get scrollbars at all (vertical scroll policy is AUTO), and the outer container stretches past the bottom of the screen, causing the entire app to get scrollbars. So it looks something like this:

I have a fairly straightforward Flex layout question. Is there anyway to get FormItem's contained within a nested container to follow the alignment of the FormItem's in in the parent form container?

The IDs for all tags in an MXML component, no matter how deeply nested they are, generate public variables of the component being defined. As a result, all id properties must be unique within a document. This also means that if you specified an ID for a component instance, you can access that component from anywhere in the application: from functions, external class files, imported ActionScript files, or inline scripts.
Which is fine if your application is all contained within one MXML, but I'm having trouble referencing IDs of components within Modules, and then inside ViewStacks/Navigation Containers within a given Module.
If I can reference a module with FlexGlobals.topLevelApplication.myModule, shouldn't I be able to reference a Panel called myModulePanel with the following?

I have a DataGrid with a custom itemRenderer(Canvas) which has a context menu on its right click. I am trying to get the data of the itemRenderer. I tried to find something in event & variables. I also tried with FlexNativeMenu on RIGHT_MOUSE_CLICK. But I didn't find any way out.

This is nested inside another for loop which creates an array of the movieClip rows. Problem I see them drawn and positioned correctly on the stage but I cant reference any other than the top row in order to change the alpha for example.
how is the best way to reference to the Instances.
View 2 RepliesI have a video player that's control bar's x & y are over the top of the video. It is set to alpha 0, and when the user rolls over the video the control bar's alpha goes to 1 and becomes visible. I have a few even listeners and a function that makes this happen. My issue is that the buffer handle and the volume handle do not go to alpha 0, despite the fact that their parents do. The instance of "volumeHandle" is the child of "volumeSlider". "volumeSlider" does go to alpha 0, then to alpha 1 on rollover, but it's child "volumeHandle, is always visible. The same applies to the respective instances of the buffer bar.
I have tried
volumeHandle.volumeSlider.alpha = 0;
But that doesn't work. My guess is that the conflict lies in the linkage of the controls for the buffer and volume handles.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
(Actionscript 2 btw - and actually cs4, not that it really makes any difference?) I have a class that instantiates a movieclip from the library, e.g.:
Code:
debugbar:MovieClip = thing.AttachMovie("debugbar", "debugbar_mc", 999);
So attaching it to the where ever "thing" is - could be movie clip or level0 or whatever, doesn't matter as "debugbar" is a private variable of the class. Now the important part - debugbar in the library is a movieclip that contains some components - buttons and textInputs. The problem comes when trying to access these components.
I would have thought that this would work:
Code:
debugbar.input_txt.text = "hello";
In order to set the text of "input_txt", the instance name of a TextInput component on the timeline of the movie clip (put there in author time). However, this does not work. Infact, I cannot access any specific "component" properties - they come back undefined. I can however set and retrieve MovieClip properties for the "input_txt", such as _x. However there is one added strange thing with this too - setting _visible to false doesn't seem to work (however perhaps a component by default overrides this).
I also appear not to be able to add event handlers to the component - at least for the usual component events. I tried casting it to a component, such as:
Code:
var temp:TextInput = TextInput(debugbar.input_txt);
trace(temp);
which gave "temp" as null.
However if you trace the thing itself without casting to what it is, it gives the path to correctly. It almost seems like the components are somehow broken when trying to access them this way - or that they cannot be accessed this way?
The thing is, I was able to access all of this before, when the code to do it was placed on the timeline (frame 1, the only frame) of the debugbar itself, where the components were child instances. This meant I could just reference them directly too - so input_txt rather than debugbar.input_txt , although that is probably largely irrelevant. I need to have it in a class though, as I need to pass in certain objects that need to be accessed by the mc.
I'm trying to get my own buttons to load FLV movies into the FLVplayback component. I've got it to work in a simple test but making it work on a more complex level. The test is here I've named the FLVplayback instance 'my_video'The simple buttons have this script in the actions:

my_video.load("videonamehere.flv");

How do I reference a fla component from an actionscript project? I use flex builder.
View 1 RepliesIt's me again and I'm running into a problem. So, I have this movie clip that is nested inside multiple movie clips. I want to tell Flash to perform an action when that movie clip hits another movie clip in the main timeline. It's just collision detection for a game using the hitTestObject code. I was thinking of using MovieClip(root), but that won't work since it's nested so much.

I have a component in my library that I want to programmatically place on the stage and manipulate from my external actionscript file. I have a blank FLA and all the movieclips, text, etc that are on the stage have being created in an external ActionScript file and placed on the stage. However I would like to access this one component that is stored in my library without having to place it on the stage - since everything is to be done in ActionScript.

question about file reference: i have a file reference that can browse for media files (*.flv, *.f4v, *.wmv, *.wma, *.mov) i am trying to load the file Reference in to a video component. i do that by:
video.attachNetStream(ns);
ns.play(null);
myByteArray = fr.data;
ns.appendBytes(myByteArray)
flv files are OK and i can see them and hear them & controll them. but when im trying to load any other kind of movie type, the all thing fails.
I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

I am trying to use the scroll pane component and I am having a few teething troubles. I have a scroll pane as a child object of a movie clip which is essentially a 'page', if I display this page it works fine and the scroll pane does too. If I then remove this page from the display list, go to another page and come back by readding it to the display list, I get the following error, even though nothing else has changed:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at fl.containers::ScrollPane/fl.containers:ScrollPane::endDrag()
The scroll pane is still visible and works correctly, but ideally I'd like to stop this error.
