RE: [flexcoders] Re: Unbelievably embarassing question - making components talk (and modules) amongst
First, bigImage.source={data.piclink}; will not work. You cannot
use binding braces in AS code.
Second, where is the data object you reference in that line?
I suspect you really want something like:
public function thumbChanged(event:Event):void {
var xmlData:xml = XML(event.target.selectedItem);
var sPicLink:String = [EMAIL PROTECTED];
Application.application.galleries_module1.imagetabs.bigImage.source =
sPicLink;
Application.application.galleries_module1.thumbloader.thumbService.send(
);

OK well I'm I guess one or two lines from making the 'simple' version
work. When I hard-code the following in my thumbChanged method, it
works...well if loading the same image no matter what thumb you click
means it works LOL:
Application.application.galleries_module1.imagetabs.bigImage.source=a
ssets/galleries/CD2.jpg;
But when I try to grab the proper {data.piclink} which corelates to
the thumblink after clicking (i.e., the right image in the XML file),
I get, well, nothing, not even an error LOL...but no image
either...it DOES make the broken image link go blip, but it doesn't
load. Here's what I am trying to do, but please keep in mind, with
this sort of thing, I still have absolutely no idea what I'm doing
yet (the source code in the HBox works, but my thumbChanged method is
frying):
mx:Script
![CDATA[
import mx.containers.HBox;//???
import mx.core.Application;
//import mx.core.Application;
[Bindable]
public var selectedThumb:XML;
// Event handler for the Tree control change event.
public function thumbChanged(event:Event):void {
Application.application.galleries_module1.imagetabs.bigImage.s
ource={data.piclink};
Application.application.galleries_module1.thumbloader.thumbSer
vice.send();
//Application.application.galleries_module1.imagetabs.bigImage
.source={data.piclink};
//selectedHBoxItem=HBox(event.target).selectedThumb
as XML;
//Application.application.thumbService.lastResult.galle
ry.piece.piclink.url=selectedThumb.piclink;
// parentDocument.thumbloader.thumbService.send();
//Application.application.thumbService.send();
};
]]
/mx:Script
mx:HBox click=thumbChanged(event);
id=thumbbox width=100% height=100%
verticalAlign=middle verticalGap=0
verticalScrollPolicy=off horizontalAlign=center
backgroundColor=#00 backgroundAlpha=0.0
mx:Image id=img source={data.thumblink}
horizontalAlign=center verticalAlign=middle height=75%/
/mx:HBox
/mx:Canvas
As usual, the source is available if I'm clear as mud...I'd really
appreciate any help here, because I've spent all weekend on it and
I'm just totally lost:

I'm sure it goes deeper than this (if you'll pardon the pun), but
if
you add 'parentDocument' to your parent (i.e.,
parentDocument.thumbloader.etc you get the kind of thing I'm
hoping,
at least for component-to-component-from-within-the-same-module.
I typed the name of the error message into the help screen. Go
figure :S

files. Also offered me a fighting chance in the future to figure
out
model, control, and view separation.
But for me to get (for example) the tree component I made to
communicate with the thumbnail component, both housed in the
galleries module, I had to hardcode the components back into the
module (i.e., they are no longer components), so the module is now
one big-ass file that has no components, they are right in the
file.
I can't go on like this, it's just too ugly. As a designer and a
poet
wannabe, that sucks LOL.
But I can't for the life of me get things to talk amongst
themselves,
say my module has 3 custom components doing their things...how do I
access something in one component from another component?
I became very afraid when I realized there doesn't seem to be any
kind of AS2/Flash dummy-movie approach - loadMovie ('thisthing')
into
dummyclip instance 'whatever' and suddenly you just say
whatever.thisthing.stuff, and you've gained access to everything.
In
other words, you can jump up and down as long as you know the
scope.
I haven't a clue what the equivalent is in Flex 2.
It's very embarassing. I refuse to get through this weekend without
figuring it out. I'm not botching my gallery project by having 5-6
modules (as I DO want) but with thousands of hardcoded chunks
within
them, when each module should by rights have nice piecemealed
(sorry
for the word) custom components doing their thing from their own
file
and from there communicating with each other. I need to use
components in the modules for my own sanity, and even worse, how do
I
get one module to talk to another module's objects, functions, etc.?
In a word, you can't go from:
[EMAIL PROTECTED];
srv.send();
...strip it out into a component and then call the id of the
parent,
i.e.:
[EMAIL PROTECTED];
thumbloader.srv.send();
...you get Access of undefined property thumbloader for your
troubles...
You can't back up a generation like you could with Flash. Or if you
can, I'm missing big bits of the puzzle.
Any suggestions, other than take a chill-pill?
Thanks guys,
Shawn
