[flexcoders] Re: Error 1046 on custom component...

[dougmccune]

Double check the package structure and the package statements at the
top of the custom class. It sounds like maybe you grabbed the class
file from some other package structure, moved it to some other
structure, and forgot to change the package declaration at the top of
the file. When this happens the intellisense will automatically
generate a namespace, but it won't actually find the file.

[flexcoders] Re: Can drag-able content within a container, update it's Scrollbars?

[dougmccune]

If it's really a matter of scrolling a container that has scrollbars
by dragging the contents, I would use a mouselistener (as mike
suggested) that would update the verticalScrollPosition and
horizontalScrollPosition of the parent container. You wouldn't
actually be "moving" the inner stuff at all. You would sort of be
faking the dragging.

Why do it like this? 1. dragging too far one way or the other wouldn't
drag the inner components out of the viewable area, 2. if you actually
wanted to use the scrollbars as well then they would still work (and
they would update correctly as you're dragging)

Just my two cents.

[flexcoders] Re: Returning 'this' from an overridden method?

[dougmccune]

Just from first glance I'd suggest not following the design pattern of
returning the object from the function like you're doing. It seems
like the only reason you're doing it is to make it so you can write a
bunch of statements all on one line. In terms of someone else reading
your code, I think it would make a lot more sense if they saw this:

camera.move(10, 12);
camera.rotateX(45);
camera.rotateY(90);

It turns 1 line into 3 lines, but I think it's far less confusing and
this follows the same design pattern that most other Actionscript
classes follow. Methods like move, rotate, etc are used often in
various classes and usually they do what they're supposed to do and
return void. In my experience I've never really seen an OOP class that
returns itself very much.

So that's not a direct answer to your question, merely a coding
suggestion.

[flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML

[dougmccune]

You can make as many calls to addEventListener as you want. So you can
add 2 or more event listeners that get triggered for the same event.

So something like:
myButton.addEventListener(MouseEvent.CLICK, myFunction1);
myButton.addEventListener(MouseEvent.CLICK, myFunction2);
myButton.addEventListener(MouseEvent.CLICK, myFunction3);

All three of the above functions would get called when the event
triggers. You can remove each of these separately as well by using
removeEventListener and specifying the particular function you want
removed.

[flexcoders] Re: How can I test a UIComponent to see if it is user editable?

[dougmccune]

I don't think there's a good answer to this question. There's no way
to figure out via AS whether a component MIGHT dispatch a given event.

I did a search on livedocs to try to find all classes that dispatch a
change event. This only seems to include base classes, so subclasses
of any of these controls won't show up, so you'd hve to figure those
out. Also note that this doesn't mean that some classes might dispatch
other events that signify change that aren't specifically the same
"change" event. And these change events don't necessarily mean "user
input" either. All it means is that the component dispatches an event
called "change".

Here's the livedocs search:
http://livedocs.macromedia.com/cfusion/search/index.cfm?loc=en_us&term=site%3Alivedocs.macromedia.com%2Fflex%2F201++%22change%3DNo+default%22&action=Search

And here are the classes that come up:
mx.controls.RadioButtonGroup
mx.controls.sliderClasses.Slider (which means HSlider and VSlider as well)
mx.controls.ColorPicker
mx.containers.Accordion
mx.containers.ViewStack
mx.controls.DateChooser
mx.controls.NumericStepper
mx.controls.Button
mx.controls.DateField
mx.controls.PopUpMenuButton
mx.controls.ComboBox
mx.controls.TextInput 
mx.controls.TextArea
mx.controls.Tree
mx.controls.listClasses.ListBase (so that would mean all list controls
like List, TileList, DataGrid, etc)

So your best bet is probably to put together a more complete list of
each component you want to define as having "user input" and then just
check against that list using the "is" test as already mentioned. But
I think the basic answer to your question is no, there's no good way
to do this.

[flexcoders] Re: Time Entry Component

[dougmccune]

Ohh, that's a fun component. Can you make one that ticks up the
seconds (like the bottom example) but also lets you change the time?
That seems the most like the Windows one. If you change the seconds it
just starts ticking from the new value you entered.

My other comment is to ask why setting the selection on am/pm seems to
bump the width a little. Clicking any of the other fields doesn't seem
to change the width of the component, but clicking am/pm bumps it out
a little. I don't know why, something about setting the selection on
the text field, or setting the min/max values on the NumericStepper?

[flexcoders] Re: Convert ByteArray to Bitmap

[dougmccune]

If you're loading an image type supported by Flex (gif, jpeg, png,
swf) then you don't need to know anything about the image. You don't
need to know the width or height.

All you do is use Loader.loadBytes(byteArray). This would load the
image exactly the same as if you loaded from a URL.

Use a URLLoader, which gives you the ByteArray as the data property

[flexcoders] New Component Released - Animated Gif Loader

[dougmccune]

[I apologize if this is a double post, had a timeout when I first
tried posting.]

I just released a new commercial component for Flex that loads and
plays animated GIFs. This has been brought up a few times here on
flexcoders and flexcomponents. Now there's no need to hack together
some weird IFrame solution, or figure out how to do the server-side
conversion of all your GIFs. You can try the demo version for free and
the commercial version is $50. 

Here's the description I posted on Flex Exchange:

The AnimatedGifLoader loads and plays animated GIF files. This
component adds support for animated GIFs, a feature that has been
lacking from Flex.

This works just like the SWFLoader component from the Flex Framework.
Use it inline in your MXML code or by using Actionscript. This
component supports everything the SWFLoader component does, with a few
additions.

New methods: play(), pause()
New properties: autoPlay, playing, currentFrame, delay

Test it out with your own animated GIFs to see how it works by
clicking on the sample URL.

I've written up the full details on my blog. There are some examples
and you can even test out any GIF you want by uploading it and seeing
it loaded by the component instantly:
http://dougmccune.com/blog/2007/01/17/animatedgifloader/

Here's the Flex Exchange posting:
http://www.adobe.com/cfusion/exchange/index.cfm?view=sn610#view=sn611&viewName=Flex%20Extension&loc=en_us&authorid=61303741&page=0&scrollPos=0&subcatid=0&snid=sn611&itemnumber=0&extid=1103970&catid=0

Feedback is always appreciated!

[flexcoders] Casting a variable - Best Practice?

[dougmccune]

Quick question (I know both work, just wondering what people do in
practice):

Option A: var castVar:Type = uncastVar as Type;

OR

Option B: var castVar:Type = Type(uncastVar);

I've been going with using option A (with "as") mainly because calling
Array(uncastVar) or ArrayCollection(uncastVar) does not cast to Array
or ArrayCollection, but instead instantiates new Arrays, which is
confusing. So instead of trying to remember to do most of my casting
using Type(variable) unless I'm trying to cast to Array, I figured it
was easier to just always use "as". 

Also, is there a specific reason for the choice to not allow
Array(var) to simply cast to an array? It seems a little odd that
casting that works for every other datatype doesn't for one or two.

[flexcoders] Re: SEO Compatibility

[dougmccune]

I just wanted to pipe up with my opinion on this matter, because it
comes up a lot and the answers are always similar. And I get a little
frustrated because it seems like Adobe tries to say this isn't a
problem when it really is.

To reiterate this scenario: Someone asks "Why isn't Flex content
searchable by Google? Or how can I make it searchable by Google?" and
then someone invariably responds "Of course you can get your Flex (or
Flash) stuff indexed by Google! Google indexes SWFs and also here's a
bunch of roundabout ways to add textual content into the HTML wrapper,
etc, etc."

While I know Adobe employees don't like to admit this, the answer is
very simple: It is often impossible, and if not impossible then at
least extremely difficult, to get your Flex content indexed by search
engines. That's the straight answer. No more no less.

If I make a dynamic app using ASP, PHP, Coldfusion, or whatever that
outputs HTML, Google will index all the dynamic content because it
follows query-string links (or if you use mod_rewrite or whatever). So
if I have a full message board written like this then Google will
index all the content. The only way to get the same thing to happen
with a Flex app is to develop an alternative, non-Flex interface to
output the message board contents. Basically you have to make a PHP or
ASP version of your app as well as the Flex version.

I find any attempt by Adobe to pretend like this isn't a huge problem
very frustrating. EBay, Amazon, MySpace, YouTube, digg, you name any
large website and you can be guaranteed that they will not be using
Flex for the Web frontend for customers. They might use it for tons of
internal business apps (ebay) or for something that can remain
completely unindexed by Google (Yahoo Maps) or for media content
(YouTube), but they will never use Flex or Flash (as it currently is)
for the real frontend user interfaces. 

Sorry for going on a bit of a rant. But just once I'd like to see an
answer from an Adobe employee saying "Yup, this is a real problem.
What you really want to do, for all practical purposes, is nearly
impossible with Flex. We're trying to work on it but for now you're
SOL." Because that's the real answer.

[flexcoders] Re: not draggable TitleWindow

[dougmccune]

Someone else posted this same question to the list a while ago, I
extended TitleWindow to create an undraggable version. It's a pretty
simple extension, I went with intercepting the mousedown event on the
titleBar. Not sure if I had a reason for doing that instead of
overriding the startDragging method as already suggested.

But anyway, here's my code (or if it's hard to read in the email you
can go here:
http://dougmccune.com/PanelTest/bin/srcview/source/com/dougmccune/containers/UndraggableTitleWindow.as.html)

package com.dougmccune.containers
{
import flash.events.MouseEvent;
import mx.containers.TitleWindow;
import mx.controls.Button;

public class UndraggableTitleWindow extends mx.containers.TitleWindow
{


override protected function createChildren():void
{
super.createChildren();

titleBar.addEventListener(MouseEvent.MOUSE_DOWN,
stopEvent, false, 1);
}

private function stopEvent(event:MouseEvent):void {

if (event.target is Button) {
super.dispatchEvent(event);
return;
}

event.stopImmediatePropagation();
}
}
}

[flexcoders] Re: Creating JarJam button Effect.

[dougmccune]

I think this is what you want:
http://dougmccune.com/PanelTest/bin/JamJarEffect.html

View source to check it out. The key is a simple extension of
TitleWindow. It's called UndraggableTitleWindow and basically catches
the mouse down event on the titlebar and cancels it from propogating
so it never starts dragging.

You still have the problem that clicking on the button keeps making
new instances of the popup over and over, so that should probably be
fixed.

[flexcoders] Re: Uploads Needed Greater than 100 MB

[dougmccune]

I'm going to piggy-back off this post and ask a similar question: 

Why are you limited to only selecting a maximum number of files at
once when the user uses FileReference? I'm referring to when the user
selects multiple files per upload. The max limit is large, but maxes
out at something like 250 files. If the user selects more than that a
fairly unhelpful error message pops up and the file browser window
goes away.

I'd like the user to be able to queue up hundreds (400+) of files for
upload. I know it's a lot (and discussion of whether uploading
hundreds of files is ever good can wait for another day), but is this
a technical problem, or a design choice by the Adobe team?

[flexcoders] Icons formerly included in Flex SDK (Beta)

[dougmccune]

An older version of the Flex SDK had a folder called Icons that
contained a series of various UI icons. I think I read in some readme
that the idea was to provide some basic GUI elements to help
standardize the look and feel of Flex apps. 

So a few questions for someone from Adobe:
1. I have the icons from the beta install, can I still use them?
2. Is an icon set going to be included in future versions of the SDK? 
3. Why was the icon set removed?

[flexcoders] Re: Run ppt file in flex

[dougmccune]

Someone mentioned Breeze already, but I figured I'd throw in that you
can buy a single license of Breeze Presenter for about $1,000 (without
buying the server or other more expensive parts), which lets you do
the PowerPoint to SWF conversion. But you would still have to manually
convert each PPT you wanted and then figure out how to pull that into
Flex.
