RE: [flexcoders] Getting a Sprite into a Flex Container?
Thanks a lot Amol (and Maciek)! In between I found that I can go a different
way and use a TileList instead but I'm sure your ideas will be useful a bit
later for what I'm planning to do!
Maybe somebody can give me a hint with a different problem . I'm loading
several small images into a TileList Component. These images are 32x32
pixels in size. I've created my own ItemListRenderer where I'm using a HBox
(but a Canvas would do well too). My problem is that I cannot get rid of the
vertical gap between a row of tiles. I've set verticalGap in the
ItemListRenderer to 0 but there is always a gap of 4 or so pixels. But I'd
like to have no gap between the items. Horizontally there is no gap if I set
horizontalGap to 0 but verticalGap seems not to do it and I've alsdo tried
various different components for it like Canvas, HBox, VBox etc. Any idea?
Thanks Happy new year!
Sascha

Hey Sascha,
I hope this is what you were looking for.
I have a class which extends Sprite as below:
package {
public class myShape extends Sprite {
.
.
.
.
.
}
}
Now I have my owns custom component class file which I have added as
follows:
First in the Application tag of your mxml file, mention a additional
attribute as 'xmlns:greet=com.*'. Here refer to the package where your
custom component class is.
Now use following to add the component to the Flex mxml file:
greet:test id=apiref /
Here 'greet' is the xmlns which we added in the application tag and
'test' is my custom component class. You have to be careful to extend your
custom component class with the UIComponent class like:
package com {
//import myShape class if not in same package.
public class test extends UIComponent {
..
public function test() {
var shapeObj:myShape = new myShape();
addChild(shapeObj);
}
.
}
}
Now in the test class you can add the earlier Sprite extended class by
creating its object as above.
This should solve your purpose. Now the above mentioned test class can
extend any of the Classes like Canvas, or any container class. But
UIComponent happens to be the base class to all the container classes n so
UIComponent could be best opted choice.
Regards,
Amol.

Hi,
I got a class that extends Sprite that I want to put into a Flex
DisplayObject container (Canvas or any similar custom made component). My
question is:
Is implementing the IUIComponent interface the only way to get this working
or
Are there any other ways around it? A SWFLoader is not what can use in this
situation. Any hints would be appreciated.
Thanks in advance,
Sascha

If the data can be in one file then that is the easiest way to do it.
Use HTTPService with resultFormat=e4x to get the data into Flex.
Then use an e4x expression to return an XMLList of the correct nodes for
the first combo box.
When you have that working, post back.

[flexcoders] Closing An Open Item In Flex Tree Control
Anyone have a working example they can point me to that demonstrates how to close an open item in a Flex Tree control? After studying the Tree control in the Flex 2 Language Reference, it seems to indicate that method expandItem will also close an open item if the second argument is set to false. However, I've not gotten that to work. I can open items using method expandItem just fine. Of course, the Flex 2 Developer's Guide only has very limited information on using the Tree control's methods and I've not found anything when doing an Internet search. Bruce
[flexcoders] ViewStates vs ViewStacks in App Control
I am trying to build out a basic framework for my application and I have about 4 different screens that users can view depending on what they are trying to do in the applications: Welcome Graphics Login Screen Overview Screen Detailed View Screen Generate Reports Screen These screens don't share similar menus or components so I am thinking it is best to create a view stack for navigating between the different screens - Application ViewStack Welcome Graphics Login Screen Overview Screen Detailed View Screen Generate Reports Screen Here are my questions: 1) If I do this, can I add a loader to each child of the ViewStack so that the user does not have to wait for the entire app to load in order to start the application? 2) I could also do this using ViewStates, but it seems to me that ViewStates are more useful when there are significant shared assets components between the different states. However, performance-wise would it be better to use one over the other? 3) In the long run (should my application grow larger) would it be better to use a modular approach and load modules for each view? However because I am using Cairngorm would this add an extra layer of difficulty trying to maintain/share a ModelLocator, FrontController, etc between a number of different modules? Thanks for your advice. It always seems the design decisions are much more confusing than the actual coding!! - Kevin

[flexcoders] Flex bug? undefined state
Hi List,
Sorry for the long winded post, but I'm completely baffled by an
exception that my app is throwing involving an allegedly undefined
view state. I have bound the current state of an item renderer
component to an expression that returns one of several possible state
names.
mx:currentState{calcCurrentState(Channel(data).syncing, open)}/
mx:currentState
protected function calcCurrentState (syncing:Boolean,
open:Boolean):String {
return syncing ? 'syncing' : (open ? 'open' : 'closed');
}
Two of the states work without issues, but a third one causes
exceptions. Flex complains that the state is undefined; a claim which
seems to conflict with the evidence:
a. I have stopped the app in the debugger and observed the contents
of the states array (as it should be)
b. Although Flex claims the state is undefined, it then switches to it.
I have tried changing the name of the state, using a different state,
removing the overrides from the state, and several other tests, all
to no avail.
mx:states
!-- These states work fine --
mx:State name=closed
mx:SetProperty target={this} name=height
value=55/
/mx:State
mx:State name=open /
!-- Flex claims this state is undefined --
mx:State name=syncing basedOn=closed
mx:RemoveChild target={syncBtn}/
mx:AddChild relativeTo={syncTools} position=1
mx:ProgressBar/
/mx:AddChild
/mx:State
!-- This test state produces same results --
mx:State name=myState/
/mx:states
A stack trace follows, delineated for clarity. It appears that two
state changes are taking place. I'm not sure why that is or if it is
normal.
Thanks for any insights you can offer.
Cheers,
Lach

[flexcoders] local file access thru HTTPService fails
Hi all this seems like such a simple thing, and yet ... my project currently lives in the directory My Documents/Flex Builder 2/xmlshow and works fine. If I take the entire directory and copy it to my desktop, and then open xmlshow_app.html it no longer works. Specifically it doesn't load my file (voucherXML.xml) thru HTTPService. I repeat, this works fine UNTIL I copy the doirectory elsewhere. Is this a crossdomain issue? I've tried, experimentally, adding a crossdomain.xml file in the dame directory as the swf and it doesn't work.

[flexcoders] Re: ViewStates vs ViewStacks in App Control
This is helpful, thanks.
