View 1 RepliesIndeed they both (skins and itemRenderers) seem to do drawing using the flash.graphics.* package. I have copy pasted code between skins and itemRenderers before, so I really don't understand the difference. I have had more experience implementing itemRenderers than skins, so that might be part of the problem.

View 1 RepliesI'm binding an array of items to a data grid using ItemRenderer. I use the data variable to control the bindable data. I also have someComponentVariable that need be inserted into every row but its declared at the component scope, so the data grid doesn't seem to reconize it (compile error). How can I use this variable (someComponentVariable) inside the ItemRenderer?

I am writing a custom item renderer to render a column series in my application.
Its a stacked chart and i want to use the same item renderer for both the column series. The color for each series in the stack is different and am setting that in the 'fill' property of the two series. My doubt is how can i get the color specified in the fill property of the column series from the item renderer. if this works then i can very well use the same renderer for both series.
I've wrote a custom itemrenderer for a List component (Flex 3.5) which is a VBox with a Label and a TextArea wrapped inside. All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this?
I've already added an event listener that selects the item at index 0 but the textArea in it should also be focussed at that moment _list.addEventListener(FocusEvent.FOCUS_IN, onListFocusIn);
private function onListFocusIn(e:FocusEvent):void
{
_list.selectedIndex = 0;
}
I'm writing a s:ItemRenderer to render some simple graphical components in my app. Each element can have multiple shapes that can be selected by the user, i.e. a certain element can be a square, or a circle, or a star, or whatever else.The simplest way I could think for doing this was to include all possible shapes in a s:Group and then manage their visible tag depending on what shape the user has selected. Is there a better way to do that? Also, if I encapsulate the group in a separate MXML component, how do I propagate the state of the itemRenderer (say "hovered") down to the MXML component that manages the shapes?Let's say you want to display three types of objects alternatively - the IR below with an AS snippet that turns visible to false for 2 out of the 3 objects definitely does the trick, but seems so ugly to me. In the mean time I found setCurrentState (stateName: String, playTransition:Boolean=true) to propagate the state down, so that's solved.[code]

I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">
I have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.

I 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?
So I was working normally, and accidentally hit the profiling button after that, I later decided to export my current.air.URL...Why would the export button disappear all the sudden? I cannot find it at all. It seems rather interesting not being able to export a .air and provide an installer.
View 1 RepliesI 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 have a list with a itemrenderer. When I put a button in the itemrenderer I can not interact with it. If I rollover the button the list item rollover is triggered but not the button's rollover. I can't click on the button either.

Why is it such a pain to put a button in an itemrenderer?[code]...

View 2 RepliesSkinParts 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.
