RE: [flexcoders] Eliminating scrollbars
The first trick is to get the scrollbars to appear on the VBox and not the app. That's the main reason you got clipped. Try this: ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute height=300 mx:VBox id=vb width=100% height=100% minWidth=0 minHeight=0 mx:Box id=box width=100% minWidth=0 minHeight=0 height=20 backgroundColor=red borderColor=blue borderStyle=solid borderThickness=8 / mx:TextInput id=boxSize width=100 change=box.height=event.currentTarget.text / /mx:VBox /mx:Application From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Paul Andrews Sent: Friday, November 30, 2007 5:19 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Eliminating scrollbars It's my fault - my post wasn't too explicit. I wasn't particularly thinking of vertical scrollbars. Let's say you had a vertical scrollbar and a width of 100%, this now means you also get a horizontal scrollbar because you can't get the 100% for the component (because of the scrollbar), so a horizontal bar will appear. I really don't want a horizontal bar and depending on content and context I might not have a vertical scrollbar either. So really it's more a case of when you have one scrollbar and don't want two of them! This is the scenario I had in mind: ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml http://www.adobe.com/2006/mxml layout=absolute height=300 mx:VBox id=vb width=100% mx:Box id=box width=100% height=20 backgroundColor=red borderColor=blue borderStyle=solid / mx:TextInput id=boxSize width=100 change=box.height=event.currentTarget.text / /mx:VBox /mx:Application If you make the box too high, the vertical scrollbar appears and also a horizontal scrollbar. Of course, when the height is small enough there is no vertical scrollbar. I'd like the box width to track the available space so that no horizontal bar appears. The lazy approach with a magic number less than 100% does do the job, but it would be nice to see how others approach this. If I deliberately suppress the horizontal scroll policy, the vertical scrollbar will be over the box, obscuring part of it.

Re: [flexcoders] How much can AIR and the OS interact?
Ok...so Flex can't interact with DLLs but another thread (new to Flex) suggests that a possible alternative. lternatively, you can write a server application in C++, Java or C#/.NET that interact with those devices.

Re: [flexcoders] How much can AIR and the OS interact?
Yes, flash speaks to sockets and so you can communicate with any net accessible object including localhost.

works (all data is shown, and clicking in the date field opens the

Simply because each release theoretically got better w/o degradation in
other places. I know that's not totally true so a few of you are
relying on older releases, but I often find myself looking at these
examples on to realize they got fixed already.
It would also depend on how close I am to shipping. If I'm just about
ready to publish, I probably wouldn't upgrade either, but otherwise, if
I saw what appeared to be an obvious problem, I would certainly at least
try it on a 'latest' release.

Sorry, but I obviously my question isn't clear.

I want to know what this mechanism in the Flex language is called and where I can learn more about how it? This question is not about Cairngorm.

[flexcoders] RangeError: Error #2006: The supplied index is out of ... With dynamic Repeater
My application creates new tabnavigator tabs using a Repeater driven
by a dynamically updated arrayCollection. I hope there's a simple fix
to this runtime error that's been dogging me for several days.
I'm using this arrayCollection as the data provider:
mx:ArrayCollection id=repeaterAC
mx:Array id=myRepeaterArray
mx:Object label=0 data=0/
/mx:Array
/mx:ArrayCollection
--
Here's the repeater MXML snippet:
mx:Canvas label=Personal Info width=100% height=100%
mx:TabNavigator id=tabnavPersonalInfo
x=0 y=0 width=100% height=100%
mx:Repeater id=rptApplicant
dataProvider={repeaterAC}
recycleChildren=true
mx:Canvas label=New {rptApplicant.currentIndex}
width=100% height=100%
id=personalTab
horizontalScrollPolicy=off verticalScrollPolicy=off
creationComplete=bringApplicantDataForward()
!-- form elements omitted --
/mx:Canvas
/mx:Repeater
--
This function is the click event for a button. It adds an item to the
arrayCollection triggering the 'repeat' and it sets the focus to the
newly created tab:
private function tabnavPersonalInfo_addTab():void
{
var myInt:int = myRepeaterArray.length;
var myVar:String = myInt.toString();
repeaterAC.addItemAt({label:myVar, data:myVar}, myInt);
tabnavPersonalInfo.selectedIndex=myRepeaterArray.length;
}
--
This is the run time error thrown by Flash Player 9 when the 'button'
is clicked to run the above function:
RangeError: Error #2006: The supplied index is out of bounds.

When I click Continue in the error window, all is well (the newly
'repeated' tab is created with all it's visual elements and focus is
set to it). I have tried using a try{} catch(error:*){} structure,
but it did not 'catch' this error. I've also tried changing the array
index to different values, but what you see in this code works.
FWIW, nowhere in my code do I ever removeChild()... only add via the
Repeater.
How do I avoid the error or how can I suppress the modal runtime error
window?
Any ideas would certainly be appreciated!
TIA,

Re: [flexcoders] AS3 classes as MXML to enclose other tags
Of course. It's declaratively extending a class and everything
declaration enclosed is an instance of some (other) class. I totally
forgot that you can also extend classes in mxml.
Thanks Shaun. That's the answer I was look for.

I think(without looking at the generated code) its basically composition.
As you are aware you have extended an existing class(ServiceLocator).
The wrapped tag (a RemoteObject) is an instance variable contained in
your ServiceLocator subclass.
I don't think there is much more to it than that but i'm pretty much
guessing as I havent actually looked at the generated code.
?xml version=1.0 encoding=utf-8?
cairngorm:ServiceLocator
xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:cairngorm=com.adobe.cairngorm.business.*
mx:RemoteObject
id=addcontactService
destination=addcontactService
showBusyCursor=true
result=event.token.resultHandler( event );
fault=event.token.faultHandler( event );
/mx:RemoteObject
/cairngorm:ServiceLocator
Your component is extending ServiceLocator and I image it will have a
reference to a RemoteObject and the reference is called addcontactService.
If it was as3 it might look something like:
class Foo extends cairngorm.ServiceLocator{
protected var addcontactService:RemoteObject;
//etc. etc.
}
I suppose I should actually check this for myself. :)
HTH.

[flexcoders] Re: AS3 classes as MXML to enclose other tags
This really isn't rocket science. Suppose you have an AS3 class defined
like this:
package controls {
import mx.controls.Alert;
public class MyAlerts extends Alert {
[Embed(source=../images/error.gif)]
private static var iconError:Class;
public static function error(msg:String,
closeHandler:Function=null):void {
show(msg, Error, Alert.OK, null, closeHandler, iconError);
}
}
}
This defines a new Alert class called MyAlerts. You name the file
MyAlerts.as and put it in the controls directory. Now you can do this:
?xml version=1.0 encoding=utf-8?
mycontrols:MyAlerts
xmlns:mx=http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml
xmlns:mycontrols=controls.*
mx:Script
![CDATA[
import controls.MyAlerts;
public static function showMsg(msg:String):void {
MyAlerts.error(msg);
}
]]
/mx:Script
/mycontrols:MyAlerts
Save this bit of code in MyErrorMsg.mxml. As far as Flex is concerned
MyErrorMsg is another class that extends your MyAlerts class, so you can
now do this:
?xml version=1.0 encoding=utf-8?
mx:Application
xmlns:mx=http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml
xmlns:myerror=controls.*
layout=absolute
mx:Script
![CDATA[
import controls.MyErrorMsg;
private function showErrorMessage():void {
MyErrorMsg.showMsg(This is bad! Very bad!!);
}
]]
/mx:Script
mx:VBox height=300 width=400
borderStyle=solid
cornerRadius=5
horizontalAlign=center
verticalAlign=middle
backgroundColor=#ff
mx:Button horizontalCenter=0 verticalCenter=0 label=Show
Error click=showErrorMessage()/
/mx:VBox
/mx:Application
Get it now? Flex treats all .mxml files and .as files as separate
classes, so when the base tag in an mxml file is your custom class, the
mxml file is just creating another class by extending your custom class.
You could have done this in actionscript instead of mxml for the
MyErrorMsg class:
package controls {
import controls.MyAlerts;
public function MyErrorMsg extends MyAlerts {
public static function showMsg(msg:String):void {
MyAlerts.error(msg);
}
}
}
In either case, the application mxml file would have been the same.

Randy

RE: [flexcoders] Height Problems of List component using itemrenderer with different row height
Looks like I need to add another chapter to my blog about item renderers.
Several folks have struggled with wordwrapping text in renderers. I strongly
recommend taking the code from ListItemRenderer and working from there because:
1) It is in AS and so will be lighterweight than this nest of containers
2) it makes it easier to control scrollbars
3) It makes it easier to handle explicitWidth
The lifecycle for renderers is different than for components in an MXML file.
The renderer is instantiated and added to the display list (or recycledfrom the
free list), assigned a .data item, given an explicitWidth and measured to
determine its height. % width/height is ignored in the top-level containers
and the measure method needs to respect the explicitWIdth property. It is much
more top-down than for regular components which are measured from the bottom
up. I hacked some values and binding into your example to get it to work. To
generalize, you'd have to call getStyle() on horizontalGap and factor in the
button's size. To me, it is always much cleaner just to write the AS code
instead of having all of these containers.
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:view=*
verticalScrollPolicy=off
horizontalScrollPolicy=off
mx:VBox id=testVBox width={explicitWidth} height=100%
horizontalScrollPolicy=off
mx:HBox width={explicitWidth} id=testHbox
mx:VBox id=nameBox width={explicitWidth - 24}
mx:Text id=testText text={data.label} selectable=false
width={nameBox.explicitWidth}/
mx:Label id=testLabel text={data.data} truncateToFit=true
selectable=false /
/mx:VBox
mx:Button id=testButton width=16 height=16 buttonMode=true/
/mx:HBox
/mx:VBox
/mx:Canvas
However, in poking at this, your example did expose a bug that we'll try to
squeeze into Flex 3 before it ships. The measureHeightOfItems does not factor
in paddingLeft/Right. I had to set it to zero in the main app otherwise
scrollbars popped up.
HTH,

With the default renderer with wordWrap = true and variableRowHeight= true it
works if I´m setting the height of the list after calling
measureHeightOfItems().
But it is not working if you are using more sophisticated ItemRenderers( e.g.

Hi,
My problem is following:

want to know how much space it needs to display all of its items.
This only works with single label renderer or renderer with a fixed
height, but not with renderer with different row height with Text component.

Hi!
Thanks to Alex's help I got the datagrid tab order functionality I

Just one minor issue now, which I *might* be able to just ignore, but
I'm curious about it because it works correctly on Firefox, but not on
IE. Specifically, when I reverse-tab (shift+tab) out of my DataGrid,
the focus seems to be going to the wrong control. But it only happens
in IE.

Re: [flexcoders] unable to hide datagrid column...help please
There is something wrong with datagrid bindind. I have
tried the following two examples to hide the datagrid
column
1. First Example (Without data binding)
mx:DataGrid id=dg editable=true
mx:columns
mx:DataGridColumn dataField=Artist
headerText=Artist editable=false visible=false/
mx:DataGridColumn dataField=Album
headerText=Album/
mx:DataGridColumn dataField=Price
headerText=Price/
/mx:columns
/mx:DataGrid
When I ran the above example, first column was not
visible. Then I add dataprovider to the above example
as shown below.
2. Second Example
[Bindable]
private var dataArray:Array =
[
{Artist:'Carole King', Album:'Tapestry',
Price:11.99},
{Artist:'Paul Simon', Album:'Graceland',
Price:10.99},
{Artist:'Original Cast', Album:'Camelot',
Price:12.99},
{Artist:'The Beatles', Album:'The White Album',
Price:11.99}
];
mx:DataGrid id=dg editable=true
dataProvider={this.dataArray}
mx:columns
mx:DataGridColumn dataField=Artist
headerText=Artist editable=false visible=false/
mx:DataGridColumn dataField=Album
headerText=Album/
mx:DataGridColumn dataField=Price
headerText=Price/
/mx:columns
/mx:DataGrid

[flexcoders] Re: unable to hide datagrid column...help please
The column is not visible in my example when the xmllist is not
populated. When I bind the xmllist the column becomes visible. Is
there a work around?

There is something wrong with datagrid bindind. I have
tried the following two examples to hide the datagrid
column
1. First Example (Without data binding)
mx:DataGrid id=dg editable=true
mx:columns
mx:DataGridColumn dataField=Artist
headerText=Artist editable=false visible=false/
mx:DataGridColumn dataField=Album
headerText=Album/
mx:DataGridColumn dataField=Price
headerText=Price/
/mx:columns
/mx:DataGrid
When I ran the above example, first column was not
visible. Then I add dataprovider to the above example
as shown below.
2. Second Example
[Bindable]
private var dataArray:Array =
[
{Artist:'Carole King', Album:'Tapestry',
Price:11.99},
{Artist:'Paul Simon', Album:'Graceland',
Price:10.99},
{Artist:'Original Cast', Album:'Camelot',
Price:12.99},
{Artist:'The Beatles', Album:'The White Album',
Price:11.99}
];
mx:DataGrid id=dg editable=true
dataProvider={this.dataArray}
mx:columns
mx:DataGridColumn dataField=Artist
headerText=Artist editable=false visible=false/
mx:DataGridColumn dataField=Album
headerText=Album/
mx:DataGridColumn dataField=Price
headerText=Price/
/mx:columns
/mx:DataGrid

visible.
