RE: [flexcoders] ComboBox in Component won't open to Saved Value
Here's the code for a BindableComboBox. Save it in a file called
BindableComboBox.mxml (borrowed this code from Adobe, modified slightly):
mx:ComboBox xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=initComponent()
mx:Script

}
public function renderLabelFunction(item:Object):String {
var result:String = ;
if (labelFields.length == 0) {
if (labelField != null) {
return item[labelField];
}
else {
return item.toString();
}
}
else {
for (var i:int=0; i labelFields.length; i++) {
if (i 0) {
result += ;
}
result += item[labelFields[i]];
}
}
return result;
}
override public function set selectedItem(val:Object):void {

/mx:Script
/mx:ComboBox
Use it in your components as follows:
Get the data back from the database (or webservice, or wherever) into an
ArrayCollection that has the fields myID and myName for each item in the
combo box. Then, assign the AC to the dataProvider of the BindableComboBox
and use the component in your mxml code like this:
mycoms:BindableComboBox id=myComboBox valueField=myID
labelFields=[myName]/
I also have a search-as-you-type BindableComboBox that's a combination of
this component with an auto-complete component I found on the web (not
Adobe's) if you're interested.

Subject: RE: [flexcoders] ComboBox in Component won't open to Saved Value
ComboBox.selectedItem will only work if you assign a *reference to an item
in the ComboBox dataProvider*. This is rarely possible and is not in your
case.
What you must do is loop over the items in the CobmoBox.dataProvider and
compare the appropriate property's value to the value you want to match.
When a match is found, use the loop indes to set the ComboBox's
selectedIndex. This is simple enough to do in a one-off situation.
If you need this often, then you might want to use an extended ComboBox.
Making a generic one is a bit tricky, because the Combo Box dataProvider
items can have any properties at all. I have an example on www.cflex.net
http://www.cflex.net/ (it allows you to set the data field you want to
match) and Ben forta has done one and there are others.

You can use an iframe to display html inside a flex app. Check out the IFrame component from here: http://ccgi.arutherford.plus.com/blog/wordpress/?p=133 Also, I'm toying around with using Adobe Captivate to generate flash help files and then display them in flex.

The Flex side needs to know where in the app the user is, and be able to determine the url to display. Using ExternalInterface you can exercise quite a bit of control over that window's behavior. Doing it all in Flex will be more difficult, primarily on the editing side. Dynamic display based on xml content is easy, but building a dynamic layout that looks like a help system might be a bit tricky. Directly editing xml files is not advised for non-developers, so you would need some king of wysiwyg editor... I would really like to see a Flex integration of something like RoboHelp.

I think the problem is with the DisplayList itself, since other
objects are failing to appear, even though everything looks OK and no
errors are being thrown. I believe that the problem with the Alert
is related to whatever has thrown the display list into a tizzy. So
I'm thinking anything else trying to draw to the screen will fail in
the same way. I've figured out how to get the problem to happen
outside the wrapper, so I'm tracking it down that way.

Hey Dudes var a:String=sources/ top2Over. jpg; [Bindable] [Embed(source= a)] or public var top2Over:Class; I want to create object embed adders to be fetched by string .liek the given simple wrong code Sajid
[flexcoders] Re: Interfaces WHY?
You lost me at hello!
It's a lot easier if your class just implements what it needs and
leave the inheritance to the class framework that is implementing the
interfaces.
Can you break this down a little? TIA

WORD!
Especially in UIComponent designs, I would discourage the use of extends
with interfaces.

This is not to say don't, but careful design of User Interface interface
frameworks is needed. Adobe did a pretty good job at this.
If you were around in the Flex 2 betas especially the alpha you saw how
the scrubbed the interfaces and completely refactored out
some inheritance they used in the interface framework.

Except that pseudo sounds disparaging, and I actually like an
object
model which has multiple inheritance of interfaces and single
inheritance of
implementations (same as Java, and maybe C# too?). Multiple
inheritance of
implementation results in ambiguity. Composition/delegation is a
better
approach in my view. Lots of literature about this that the
original poster
can read.
Having said that, I did have one occasion in my career when I
followed an
example from Bertrand Meyer's book and implemented a tree node in
C++ as a
link and a list. But in general I think implementation inheritance is
over-used and multiple inheritance can get you into trouble.

And sometimes you even have interfaces with no methods. In

it's a marker (often a parent of other interfaces) and when
used in method
signatures you get type checking.

Hi,
It's ICommand.
The reason is you can stack interfaces on top of each other
allowing
more decoupling to the implementing concrete classes.
This interface is obvious. Any class that implements it needs
eval() and
only eval. It's like a singleton declaration of implementation.
If you jammed this evel() method into IUIComponent, maybe all
components
don't need eval. Make sense?
Also another good example of this type of interface in the flex
framework is IDataRenderer, it's only declared property is 'data'.

I was wondering if someone can explain why you would need an
interface
so short?
INTERFACE:
package my.package.area
{
/**
* Interface for methods that evaluate an object and return a
result.
*/
public interface IEval
{
/**
* Evaluates the input object
* @o the object to evaluate
* @return the computed result value
*/
function eval(o:Object=null):*;
} // end of interface IEval
}
USAGE OF INTERFACE:
if (value is IEval) { value = IEval(value).eval(o) };
Cairngorm has a short interface like this as well, though I cannot
remember what it is. In Cairngorm they say its for naming or
to make
the code easier to understand? I am just not sure why you would do
this? Help me see the light!
