Re: [Flashcoders] Some feedback on a coding design question
Thank you for the reply. I will take a look at the state Pattern.
Reading your post, I does look a bit like what I proposed. In the state
pattern, I would probably create the layout and the types of buttonsets
for the panel create in a object. The state of the panel then determines
wich state to load and display using composition.
Did I understand your comment correctly?

Jiri,
Sounds like the state pattern would be helpful here. Define a class for
each state of the application. Each class will contain methods for
actions the user can take in that state, like selectListItem. When the
user takes the given action (ex., selecting a list item), the associated
function in the current state is called, and the correct actions are
performed. Once those actions are performed, move the application to
the new state. Essentially the current state class decides what actions
to take in response to user interaction with the application.
Thanks,

Subject: [Flashcoders] Some feedback on a coding design question
Hello List,
I am currently building an application that uses panels. The Panels
implement a Composite Pattern. The panel holds instances of
panelButtonSets class.
The panel displays certain sets based on a selected item in the client
code.
Now my question is, how do I get around a lot of if statements in the
panel like so:
if(clientcode.selecteditem.type == 1){
panel.addSet(position_panel)
panel.addSet(rotation_panel)
panel.addSet(edit_panel)
}else if(clientcode.selecteditem.type == 2){
//different sets of button sets
}
etc...
One solution I am thinking about is the following, but I would like to
get some feedback on this approach.
BasicButtonSet() {
addSets(new panelButtonSets(position_panel))
addSets(new panelButtonSets(rotation_panel))
}
ColorButtonSet() extends BasicButtonSet {
addSets(new panelButtonSets(color_panel))
addSets(new panelButtonSets(brightness_panel))
}
var basicSet:ButtonSet = new BasicButtonSet();
var colorSet:ButtonSet = new ColorButtonSet();
Then the selected item holds a reference to a certain set that can be
loaded into the panel.
var set = selectItem.GetButtonSet();
Panel.loadSetObject(set )
{
for every set in the parameter set, call its render method and place
it at the right position
};
The thing in this solution is that every set is allready instantiated
and therefore is probably a quit expensive solution?

Re: [Flashcoders] An error I cant iron out...
It's hard to guess at this without seeing the code. Typically, this happens when you're trying to instantiate something that isn't a class or is a circular or conflicting reference. Something like var myJunk:NotAClass = new NotAClass(); or var mc:MovieClip = new MovieClip(); mc = new IsAClass(); These are off the top of my head, and might result in different TypeError or ReferneceError, but it wouldn't hurt to try to look for these examples.

[Flashcoders] Access
Hello,
I'm having some trouble with AS3, basically if I create a movieclip using the
Flash IDE and give it an instance name of mc_one, I'm unsure how to access it
from an external actionscript class.
Currently on the root timeline I have...
var _mainClass:mainClass = new mainClass();
Which instantiates the mainClass and within the class I need to access
mc_one, but obviously _root.mc_one will no longer work.
I have tried this:
/* ... */
public class mainClass {
public var mc_one:MovieClip;
public function mainClass()
{
trace(mc_one); // Outputs null
}
}
The trouble is this solution does not work, it outputs null rather than [Object
MovieClip]

Re: [Flashcoders] Access
have you tried without the line public var mc_one:MovieClip;?
it's my understanding that instantiating it by physically dragging it
out of the library and giving it an instance name is the declaration
- the way you're doing it would give a local variable the name with
no value, hence mc_one = null

Re: [Flashcoders] Access
You may have to wait until your MovieClip is initialised / on the stage
before you do things with child clips.
http://www.senocular.com/pub/kirupa/as3tips_p6.html
There is a tip in there about the DocumentClass and listening for the
ADDED event. There is also an ADDED_TO_STAGE event for later versions
of FP9.
This is similar to the onLoad / onClipEvent(load) from olden days -
there were sometimes problems accessing child clips because they had not
been loaded yet.

Re: [Flashcoders] AS3 MouseEvent target?
which is mouseChildren = false. In my humble opinion I do not think this is what he needs. He should not be referencing target, but instead he should reference currentTarget. If you are adding a listener, the handlers e.currentTarget will point to the object that you added the listener to, e.target is the object that initiated the event (event bubbling). So in a general way, where you in AS2 were using e.target you should now use e.currentTarget. You only use e.target if you want to reference the displayObject that initiated the event. Greetz Erik On 3/31/08, Steven Sacks [EMAIL PROTECTED] wrote: IMO, explaining Event Bubbling as the reason the TextField is the target is complicating the immediate solution he needs, which is mouseChildren = false. Yes, it's Event Bubbling that's causing the target to be the TextField. To understand Event Bubbling, read about it in the docs, or better yet, in a book (like Moock's). But, then you MUST do it yourself to learn how it works. If you don't play with it yourself, you will never get it no matter how much somebody explains it to you. I'm fully convinced of that.

Re: [Flashcoders] AS3 MouseEvent target?
This behaviour can not emulated precisely because there is no way for us to set the target and currentTarget properties. This is done by internal EventDispatcher code. The EventDispatcher code works something like this: - check if the target property of the event has been set, if not set it - set the currentTarget property - check if the event has the bubbles property set to true - check if the class is a DisplayObject - check if the parent property is set - clone the event and dispatch it at the parent and repeat the above steps Greetz Erik On 4/2/08, Meinte van't Kruis [EMAIL PROTECTED] wrote: so how does it work internally for displayObjects?

Re: [Flashcoders] how to check if child exists
From the help files and modified a bit. It is probably more efficient
to keep track of names and the do a getChildByName(string)
function traceDisplayList(container:DisplayObjectContainer,
DispObjToCheck:DisplayObject) : Boolean
{
var child:DisplayObject;
for (var i:uint=0; i container.numChildren; i++)
{
child = container.getChildAt(i);
if(child == DispObjToCheck){
//found it and break out of the loop
return true;
}
if (container.getChildAt(i) is DisplayObjectContainer)
{
traceDisplayList(DisplayObjectContainer(child), DispObjToCheck)
}
}
return false
}

Re: [Flashcoders] how to check if child exists
If the display object is checking itself, all you have to do is check to see if stage == null. Otherwise, you can see if its parent contains it. parentClip.contains(dispObj); that said, i'd still like to know how to determine if a display object is in the current display list? ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] some dying logic ...
granted that the eventListener was added with a weak reference
This seems to be one of the biggest mis-understandings these days. The
listener does *not*add a reference to the object that you are
listening too. For extensive discussion and proof of this issue you
can read the following thread:
http://www.mail-archive.com/flashcoders@chattyfig.figleaf.com/msg38700.html
In short: adding a listener to an object will only create a reference from
the object to the listener, not the other way around. This means that you
can remove the object without removing the listener, the object will then
still be garbage collected.

In the above code I do not see why you would need any more then the
following lines:
*basicNews = null;
removeChild(basicNews);*
All references to basicNews are now removed and it is (along with its
children) marked for garbage collection. Calling the other extra methods
seems a waste of CPU.

And yes, I wont need Interfaces unless I really feel like I HAVE to use them. In my project I have some Panels (screens) in the fla Library and each one of them is linked to a Class (linkage). Each class or Panel extends an abstract Class called APanel that extends MovieClip. The APanel Class contains some features that I need to be shared to all the other Panels. In the Main class, I managed how to switch them, based on the application flow and navigation. I use some navigation buttons that slide them to the right or to the left of the stage. Till here everything worked fine. But at a certain point I found some problematic issues. I also need the panels to slide when a certain button is pressed in one of them. Of course the function I used in the Main Class to slide the Panels away, wouldn't be available to the other classes unless I set them to be static, so I could write: Main.SlideLeft(); Fine. But to make the function static, I'd put in consideration some other things like turning some of the Main Class Properties used in the function to static. And that is a problem because library variables cannot be declared static. So I think that the use of an interface somewhere would solve the problem. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders -- Omar M.

Re: [Flashcoders] books for flash programming
A native English speaker, when learning German, will generally remark Wow! Because of this feature in German, I now understand English a little better. Programming languages are the same way. Learning another object-oriented language will help you identify how features in ActionScript work (or don't work). And learning a language from another paradigm entirely (functional or procedural, probably) will help you identify weaknesses and strengths of object-oriented programming. Not to mention that a programmer who knows AS3, Java, and Lisp is immensely more valuable than one who just knows AS3. It proves you have the capacity to learn, which is a very marketable trait.
