How do you set the default value of skinClass for a custom component in Flex? I've extended the DropDownList with my custom component, but I would like to specify a default skin to go with it instead of always setting the skinClass value for each instance.

I am trying to create a FLV playback component (in Action Script 3) where the skin hides after the mouse is idle for a certain amount of time. I've read a lot of suggestions to set the skin to null (in action script)

TypeError: Error #1009: Cannot access a property or method of a null object reference.
As far as I can tell, there is no way to toggle visibility of the skin. The best I can do is turn the SkinBackgroundAlpha to 0, which does remove the background of the skin, but not any of the buttons or bars.
when extending a flex component and trying to use it, I get a RTE. I.e. I am extending a DataCanvas and am using it like this:
<MyComponent dataProvider="{dataProvider}" width="100%" height="100%" x="0" y="0" id="dc" verticalCenter="0" horizontalCenter="0" />
Has anyone seen this? How can I get around it?

How to set skin to null for button?
button = new Button();
button.useHandCursor=true;
button.buttonMode =true;
i want to set button.skin = null
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?
I attempted to build a Flex 4 skin for a Spark button, typical practice. I adjusted the colors and other styles to my liking, including using dot selectors to specify alternate colors and such during different states. However, these are all ignored when the button is disabled. Regardless of what I do, in the disabled state, my button always has the wrong color and is alpha'd to 0.5 (even if I specifically state that alpha.disabled="1"). All the other skin states work as expected. This is my custom skin. If it were working correctly, it would appear to have no shadow or highlight, and would be a gradient grey color. Instead, it appears as a 50% alpha version of the up state (shiny green).
<?xml version="1.0" encoding="utf-8"?>

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:fb="[URL]"
minWidth="21" minHeight="21" alpha.disabled="1">
[Code] .....
This is the code used to create and then disable the button:
_action1Button = new Action1Button();
view.actionGroup.addElement(_action1Button);
_action1Button.enabled = false;
The error was that _action1Button is not the actual button, rather, it's the container of the button. Doh! Switching it to _action1Button.actionButton.enabled = false; fixed the issue.
I can still create the video and the files and it all works in dreamweaver when I preview in iexplore. When I put the files and the page into the host server it shows the skin and no video. If my paths are wrong I do not know where to check them. I need help MY whole career is on hold until I know how to do this like clockwork/ I need step by step with creating and changing paths and uploading using cpanel or dreamweaver. getting the files made and uploaded is easy part. I have been here before and cheers to the help. I really need an in depth answer about how to do this from start to finish. I have looked at all tutorials and they all make it seem so easy but dont show anything on paths. If my video works in dreamweaver but not online live what is wrong? I am lost and on edge lost many weeks of sleep over this simple process.

I'm trying to skin the Scroller in my application so that it looks like the example mentioned in [URL] This example was done in Flex 3 and images are set in CSS. I tried to create a skin for the component Scroller and saw that it uses VScrollBar and HScrollBar. I tried to put skins for these components. VScrollBar uses separate skins for the track, thumb, decrement/increment buttons. I tried to make some changes in the skin, but they were not reflected at all in the application. I just want to create a customized scroll bar in Flex 4 with custom thumbs.

I have a custom Flex 4+ component that I am trying to make and have the skin be aware of changes to a custom property. This property will determine the graphic on the button (and some other visual changes) but the data will change constantly as it will be updated by a timer.
I've looked at untold examples and still seem unable to get the syntax correct or discover how things should be separated. I've looked at overriding commitProperties and the PropertyChangeEvent without success. So I have two questions.
1) How can I get a skin to be notified of a bound property when it changes?
2) If the data for a bound property of the component is an object, will binding work properly if a property of the object changes (or would it be better to pass each property separately)?

sometimes I remove child and trace it afterwards and it outputs null although I havent yet set it to null, why is that? and do I need to set it to null also in that case?

holderArr[loadedThumbs].removeChild(holderArr[loadedThumbs].getChildByName("photo_bg"));

I have a Android Air application, where I import a png image to the stage on frame two and converted it to a symbol as a movieclip. I am performing a hovering animation using this image as a movieclip and it works great but when I go from frame 2, where the animation is, and I move to frame 3, 4, 5, or 6, and then I move back to frame 2, my application throws a errors when referencing the movieclip again. The error is 1009 cannot access null object reference. So to me it seems that once the timeline moves away from frame 2 it wipes away the reference to the imported image converted to a movieclip....is this correct? Is there a way I can keep the timeline referencing the this image as a movieclip so I can always come back to this frame?
View 1 Repliesi have a sequence of buttons and each button has its own icon. I was wondering if I have to create a Spark skin file for each button in order to assign its icon.
View 1 RepliesI am having trouble wrapping my head around the spark skin class in relation to it's host component. Basically, from what I've seen with most every skin that comes in the Flex 4 framework they don't directly expose the properties that are dynamically being set in the host component. Instead, they define states that get exposed to the skin class to define when a component should look different. This is all fine and dandy when you have a very simple component with a standard set of states, but when you have twenty different properties (hypothetically) to set in your host component that should change how the skin looks it could get very complicated very fast.
The way that I've seen that they have used to get around this is by overriding the commitproperties and invalidate functions in the skin class, grabbing the values for the properties they want from there, and then setting them to a locally instantiated variable inside the skin class. This is fine, but I feel like that is just a patch workaround to it which makes things a lot more complicated than it needs to be.Is there any way to directly expose a bindable property from the host component class so when you define your skin class it is directly ready to be read from? Let's say you have custom button with a boolean property of 'selected'. In the skin class, you want to add in a get and set function for the property 'selected' so you can perform some action upon your skin whenever it's set. How do you tell the skin class that this is an available property for you to work with from the host component?
I have a Flex Tree component in my app. I set the icons for open and close.
BUT I can't find something about changing the default background-color from white to something different.
obviously there is no background-color setable in css...
I have created a simple mxml file with code as follows:
<s:application..........>
<s:BorderContainer>
<s:SkinnableContainer id="firstRow"/>
<s:SkinnableContainer id="secondRow"/>
<s:SkinnableContainer id="thirdRow"/>
</s:BorderContainer>
</s:application>
Now I want to apply different font size, font color and font type and background color on each row i.e each of the three skinnableContainers.Currently I have defined 3 different skin classes for each of row but I think this is a bad programing. I should create a single skin class for outermost container i.e BorderContainer and any how provide different fonts and background color to all the 3 child containers through that skin class. So, is it possible that I can create single skin class that can provide different decorations to each of the child container.
For example the spark ComboBox.Where is the default skin?Is it generated (at compile or runtime)?If it was in fact written by someone how does the compiler/Virtual Machine know where to find the skin class? I didn't see a location specified in the ComboBox source.
View 1 RepliesI am loading a component which makes a HTTPService call to get data that will then be used to set certain variables in the component. I make the HTTPService call in an init() function (for the initialization event) and then set the variables according to the data received in the HTTPService result handler. However, the variables are still null at both the initialize stage and at the creationComplete stage. If I try and read the variables in a creationComp() function (for the creationComplete event), those variables are still null. Is this correct?
I guess I don't understand the flex initialization cycle very well. When are those variables actually set and available to be used? I need to manipulate those variables automatically after the component loads. Is there an event that comes after creationComplete that is appropriate or some other way to approach this? I am using Flex 3.

SkinParts are a great way to add event handlers and logic to an object that is instantiated in the skin, away from any business code. Often, though, I find myself wanting to do the opposite, and define parts that will be used in reusable, skinnable containers in the parent mxml files which will be inserted into the skinned containers.
What's the best practice for when you want to be able to define a control and a skin which can be reused with different controls inserted from outside the skin? Edit: A better way to put this might be that I want to use something that works a little bit like a SkinnableContainer, but that isn't limited to one area where content can be placed.
I have a weird issue (weird because it is specific to one component) with applicationComplete in a fairly simple application. All the UI components are declared in MXML.
