RE: [flexcoders] Simple SimpleButton 2nd try
I think you want to add mx.controls.Button which inherits from
UIComponent vs. flash.display.SimpleButton, which does not. You're
kinda confusing the Flex framework with the Flash Player API.

RE: [flexcoders] Simple SimpleButton 2nd try
Hello?! If the code you're prsenting is what you're doing, you're still
doing the same thing. You need to import mx.controls.Button and add
THAT, NOT flash.display.SimpleButton.
new SimpleButton() gives you an instance of SimpleButton not an instance
of Button. Button will work with addChild, but SimpleButton will not.
I think you need to spend a little time studying the inheritance
heirarchy of Flex vs. Flash. You are trying to unsucessfully co-mingle
them.

Re: [flexcoders] Simple SimpleButton 2nd try
1) I don't understand what you mean because the code below says import
mx.controls.Button NOT OT flash.display.SimpleButton
2) I really really wish I could find something to study, I've got half
dozen books and I look at the language ref all the time but ther seems

there is no simple example of a SimpleButton on the SimpleButton page.

RE: [flexcoders] Simple SimpleButton 2nd try
Let's keep it simple. Just importing mx.controls.Button isn't going to
make the statement new SimpleButton() return anything BUT an instance of
SimpleButton.
My advice: skip SimpleButton. Replace SimpleButton with Button. It will
work.
What you're having problems with is basic OO stuff, not Flex/Flash. I'd
spend some time getting more facile with OO concepts like Classes,
Instances, Inheritance and so forth. Then you'll have an easier time.

Re: [flexcoders] Simple SimpleButton 2nd try
From what you have posted it looks like some of the flex framework code
assumes that your child is an IUIComponent even though the API is
addChild(child:DisplayObject)... since SimpleButton IS a DisplayObject
and IS NOT an IUIComponent you are getting hosed. Looks to me like you
have found a framework bug... or at least a lack of documentation. As
others have suggested, using Button will work (because Button is a
UIComponent which implements IUIComponent)

Re: [flexcoders] Simple SimpleButton 2nd try
Yes that helps, thanks. I can accept that maybe it is not working
right, that's not a big deal. Its a big deal if its working right and I
still can't get it to work.

From what you have posted it looks like some of the flex framework

you have found a framework bug... or at least a lack of
documentation. As others have suggested, using Button will work
(because Button is a UIComponent which implements IUIComponent)

What you're having problems with is basic OO stuff, not Flex/Flash. I'd
spend some time getting more facile with OO concepts like Classes,
Instances, Inheritance and so forth. Then you'll have an easier time.

We’ll have to make sure the rules are more clearly documented.
There is no function overloading in AS so we can’t restrict what you
pass into addChild. But frameworks do have rules for performance
reasons so we can assume that all other pieces are all part of the
same framework. Sprite, SImpleButton, Shape and MovieClip are Flash
entities (note the flash package) and mx.* packages are Flex entities.
The rules for Flex are:
Navigator children must be Containers
Container children must be IUIComponents
UIComponent children can be anything including Flash display objects.
I swear I type those three lines once every two weeks. Anyone want to
help me turn it into a haiku?

Re: [flexcoders] Simple SimpleButton 2nd try
I think that you can add a SimpleButton to a UIComponent and then add
that UIComponent to the Application. But you should know that a
SimpleButton has no skin and unless you define it's states it will not
appear on the stage.

Re: [flexcoders] Simple SimpleButton 2nd try
Those layers were a big stumbling block for me, but once I understood it I don't have any problems with it. I also agree that better examples would be useful/helpful and if Adobe were to want to hire an experienced developer to write some Do you know if there are any plans in the future of the language to add overloading? What about meta-data, could there be a tag you could add to those calls that would instruct the compiler to do a type check other than what the function signature says? Alex Harui wrote: Better examples will always be useful. However, I think another stumbling block for you and others is that there are different layers out there. The flash.* packages represent a layer, and the mx.* packages represent a layer on top of that. The flash.* layer doesn’t really know about the mx.* layer and thus does not reference it in its examples. The mx.* layer expects you to use mx.* entities and therefore doesn’t point out that there are rules for mixing in-between layers. And the language doesn’t support overloading so the APIs can’t help you out at compile time. I’m old enough that I’ve seen this layering in Windows file APIs so maybe I’m more willing to roll with it. There are different file API layers in Windows/DOS and you can’t mix those most of the time either. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

Re: [flexcoders] Simple SimpleButton 2nd try
__,Is it because they think its too simple to explain ? I don't think that's the problem either. I personally think 99% of the documentation in Adobe products is horrid, but it's because it's being written by the wrong people. It's written by employees who use this stuff day in and day out and are way overqualified to think like a beginner. So they tend to skip over the basic stuff and just say do this and half the audience is screaming how? I know the documentation is available through the beta process, but how many of us file bugs on suggestions for better explaining it? I have filed a few bugs on docs, but it was for mistakes . .not a critique on the content. At the very least, I think there should be technical editors made up of people like us. Nancy
