[flexcoders] Re: How can I overlay a UIComponent on top of my application?

[bithroop]

Heh, well funny part Tracy is that in looking at my app, I have a
ViewStack that is the child of the app, and it is what is driving the
horizontal layout. The app is set to horizontal, but it is doing
nothing (except for eating cycles laying out its one container).

Anyway, I set the app to absolute, put the overlayed component to
Application.application, and it's all good.

And I was so wanting to have to defile SystemManager. :)

Thanks

 You could put a 100% HBox as the first child of the Application.  Then
 you'd get your horizontal layout, plus have a place to put your
 explicitly positioned elements.

 Hmm.. I might not be understanding what you're suggesting, but...
 
 I have the exact component that I want to overlay... really the
 question is what to addChild it to. Can I access the main
 displayContainer and if so how? My Application.application uses
 horizontal layout so it's not a candidate.

[flexcoders] Styling extended Flex Components... simple misunderstanding?

[bithroop]

I think I'm not understanding something...

My app has a bunch of .mxml classes that extend TitleWindow
(singletons in a UI). I want them all to be styled the same EXCEPT for
I want each one to have a custom background color. Here's how I'm
attempting this...

-begin external css file---

TitleWindow 
{
   borderAlpha: 0.9;
   borderThicknessLeft: 4;
   borderThicknessTop: 0;
   borderThicknessBottom: 16;
   borderThicknessRight: 4;
   roundedBottomCorners: false;
   headerHeight: 20;
   backgroundAlpha: 0.33;
   highlightAlphas: 0.29, 0.02;
   headerColors: #ff, #cc;
   footerColors: #e7e7e7, #c7c7c7;
   dropShadowEnabled: true;
   backgroundColor: #ff;
}

ExtendedTitleWindowA
{
   backgroundColor: #ff;
}


ExtendedTitleWindowB
{
   backgroundColor: #00ff00;
}

-end external css file---

So... this doesn't work. What is happening is that everything that
extends TitleWindow looks the same and the custom backgroundColors are
not taking.

The css is linked via the top level application. 

Can someone set me straight?

addEventListener(testEvent, someHandler, true) //is capture needed?

[flexcoders] Events and Non-Display Objects

[bithroop]

General question here...

I understand Event flow with objects in the display list. They flow
either up (bubbling) or down (capture) between parent and child. Maybe
an oversimplification but my question really is about how to handle
events with objects that are not in the display list. How do you pass
events from them? Like for instance, I've got this situation here...

I have an MXML that is just an mx:Object. It's MXML because I'm
defining some remoteObjects in it and that's just way more fun to do
in MXML than in AS. So anyway, regardless, the methods inside are
static and I don't want to draw the thing. It just needs to hang out
and be available so I can make these remoting calls.

So there's the rub. How can this MXML talk back to where it was called
from? Can I use events for this or do I need to send a callback function?

Any wisdom here would be awesome... this has been befuddling me for a
while.

[flexcoders] Re: Events and Non-Display Objects

[bithroop]

Thanks for the responses so far. I need to clarify what I'm asking I
think. 

I realized after I wrote my post that since I had extended mx:object
with MXML that I wouldn't be able to dispatch events from it. That
really wasn't my issue though. Let's back up and say that I had
extended EventDispatcher, or for that matter, something that _could_
be a display object but isn't in the display list, like mx:Canvas.

What I'm really wondering is who can hear events dispatched from
instances that aren't in the display list (have been instantiated but
not addChild'd). Can any object at all? Can I direct who can hear
them? My impression is that if an instance is not in a display list
then it is effectively deaf and mute as far as events are concerned.
This seems wrong, but I don't know how else it should work.

 You can adopt the following two options to achieve
 your requirements.
 
 1. Your MXML Object should Implement the
 IEventDispatcher interface and internally it creates
 an instance of EventDispathcer class and delegates
 calls to that instance.
 
 2. If you dont want to use built-in event dispatcher
 and you want to define your own function definition,
 then you can defines an interface and all the
 listeners should implement that interface. Moreover,
 you should methods in your MXML Object to register and
 unregister those listeners and call the specific
 method of that interface on some condition.
 
 Gordon, I want to ask you a few questions regarding
 event dispatching mechanism of default
 EventDispatcher.
 
 1. Does EventDispatcher calls the listeners
 synchronously or asynchronously?
 
 2. Does the EventDispatcher make copies of the event
 object provided to EventDispatcher's dispatchEvent
 function when calling the listeners? Let say, I define
 2 listeners for specific event type. The first
 listener modify some properties of the event object.
 Do the second listener get the modified one or the
 copy of the original one?

[flexcoders] htmlText resets formatting... why?

[bithroop]

I'm having an issue that maybe someone has run into before.

I've made a simple rich text editor which edits a model that has an
htmlText property as a string. The model is bound to a textArea and
the editor which sets the properties of a textRange derived from the
selection on the textArea. The editor provides formatting controls but
no typing area, and the textArea is just for typing text. So the
binding looks like this

Editor - Model - TextArea

Anyway, what I'm seeing is that the first time I create some formatted
htmlText, it all sets properly through the chain. The bug is where I
then simply add or remove letters without changing any formatting.
That causes all formatting to reset.

However, if I alter the formatting in any way, it propagates through
alright and all formatting is preserved. Seems like some flag is being
set when formatting is changed, yet that flag is not set when it's
just a text change.

Does this ring a bell for anyone?

[flexcoders] Re: htmlText resets formatting... why?

[bithroop]

So, to follow up with myself...

I ended up fixing this by unhooking bidirectional binding and instead
use a regular Event.CHANGE listener on the textArea. There was some
wack binding that was getting fired off right around where
UITextField's validateNow() method was getting called. Unhooking the
bind and only having the textArea update the model when it is typed in
made it work properly.

[flexcoders] Disappearing content/Platform Differences...

[bithroop]

I have been developing on an XP SP2 box and a Macbook, bouncing back
and forth. Tonight I started having a problem where a remoting call
was throwing an error on the PC but the Mac was fine.

So I decided to grab my wife's laptop and see how the app did on hers.
I was shocked and saddened to see that some functionality that works
fine on the other two machines goes bad on hers. Specifically, content
that I do a startDrag() on seemed to disappear. I have no idea what is
going on, but in order to sleep tonight, I wanted to ask...

a) Is this common in Flash land? I picked this platform because I
thought I'd be able to avoid this.

b) When you run into cases like this, what do you do? First thing that
came to mind was to do a remote debugging session off of her computer.


FWIW, her machine is a Dell Inspiron 640m. I tried updating the Intel
gfx drivers, but no luck.

Any insight would be great.

[flexcoders] When $height != height...

[bithroop]

I've got a component called ItemContainer that extends UIComponent.
Inside it has a TextArea. I want ItemContainer's height and width to
update to match the height and width of the TextArea when the
TextArea's are changed (I've got a resizer class that lets you drag a
widget to change the width/height of the TextArea). 

What's happening is that the .width and .height of the ItemContainer
are being set properly, but when I do a getBounds on that same
ItemContainer the $height and $width from mx_internal are different.
They are the same values as the previous time they were committed. 

I am not well versed in overriding updateDisplayList or
commitProperties, so I'm wondering what order I need to do things in
to make the internal $height and $width the same (ie, valid). This is
also not an intra-frame ordering issue... the difference between
$height and height persists until I manipulate it again which can be
any number of frames later.

Any thoughts on this would be great.

[flexcoders] Component rendering inconsistency once placed...

[bithroop]

Are there any common issues to look for when facing this situation:

I've made a new mxml component that is an arrangement of standard UI
elements inside a Panel container. The panel renders fine on its own,
but once it's placed inside another component or app, the layout goes
bad. I've cleared all explicit widths and heights as far as I can
tell, but I'm having trouble with this one.

Any ideas?

[flexcoders] Re: Where to learn intermediate/advanced Flex?

[bithroop]

I 100% agree with this.
I am very much in the same camp as you, having just started with Flex
and, well, most everything RIA related three months ago. But, I have a
project I'm trying to get done so having goals which derive from that
push my learning every day.

So pick something to make and do it. Even if it sucks, you'll be
better for it and your next project will benefit.

 Subject: [flexcoders] Where to learn intermediate/advanced Flex?
 
 
 
 I feel like I'm coming to a point now where I get the basics of Flex.
 I've got the whole component architecture down, I know the basics of
 Actionscript. I can create my own components by extending UIComponent
 and implementing the proper interfaces.
 
 But I still feel like there's so much I have to learn: and I'm not
 sure where to look anymore. I've tried looking for books: but I
 honestly haven't found one that isn't either a complete beginners
 book, or isn't written for Flex 1/1.5. I've tried looking for online
 communities around Flex, but haven't found anything really at all.
 
 Any advice on where to look next? Or should I just start tackling
 projects and learn as I go?

[flexcoders] Re: Image -shrinking and resizing

[bithroop]

I think you'll want to set the scaleX and scaleY of the image based on
the difference between the VBox's base size and its current size. 

Image has a facility to scale images down to fit, but not up, so this
might be your best bet.
