[flexcoders] RTE when setting spark gridcolumn visible property (f
I get a runtime error when I set the gridcolumn.visible property during a
datagrid initialize event. There is no problem's
if its the first gridcolumn. Looks like a bug?
Can anyone suggest a workaround?
s:DataGrid initialize=makeColumnInvisible()
s:columns
s:ArrayList
s:GridColumn id=gc0 dataField=col0 headerText=col0/
s:GridColumn id=gc1 dataField=col1 headerText=col0/
..
public function makeColumnInvisible():void
{
gc1.visible = false; // causes a RTE
gc0.visible = false; // doesnt give a problem
..
RangeError: Error #1125: The index 1 is out of range 0.

[flexcoders] data visualization with time line
Hello Guys... From last 2 months, I am working on a flex data visualization with time line. I am trying to make data presentation for my application some what like this http://www.humblesoftware.com/finance/index#finance I have spent so many hours but don't get what I wanna. Main points are. Having ArrayCollection with data (-mm-dd, y-value) using plot chart with month-year on x-axis we can change year-month range from hslider and data reflect on plot chart. I failed in hslider chart value synchronization. Any idea? Thank you, Steve Roger.
Re: RV: [flexcoders] combobox problem
Reduce the test case down to about 20 lines and post it and tell us where you
set a breakpoint. Remember that the dataProvider will be null until the
CallResponder returns with data.

Hi,
I don’t know what id is because the dataProvider not has data and the program
not enter to the loop.
I’d like to know why the dataProvider is empty when in the browser the combo
has data.
Thanks.
Rodolfo.

Asunto: Re: [flexcoders] combobox problem
In your function: public function BuscarParametroId(parametroId:int = 0):void
How do you know that the keyword this refers to the combobox?
Could you try exchanging the word this to an ID of the combo box and see what
happens?

Subject: [flexcoders] combobox problem
Hi,
I’m just learning Flash Builder and I have a problem with the combobox.
I have a datagrid and every time I change a cell it load a form with the
details.
It Works fine.
Now, in the form I have defined a combobox that it’s loaded with data using the
flex data wizard. It is loaded OK. The labels are OK. The data contains the
label and the code of the label.
My problema is that I want to pass to the combo the code of any element and
that the combo should locate that value and show the respective label. I
implemented a function that should look up on the dataProvider but when I debug
the program the dataProvider is empty.
This is the event that calls the forma and call the combo’s function:
protected function
grdDatos_selectionChangeHandler(event:GridSelectionEvent):void
{
currentState = sttMantenimiento;
libro_contable1.BuscarParametroId(tipoVoucher.libro_contable.id );
}
In the form:
s:FormItem label=Origen
partes:cbbParametros dominio=32 id=libro_contable1 /
/s:FormItem
This is the combo definition:
?xml version=1.0 encoding=utf-8?
s:ComboBox xmlns:fx=http://ns.adobe.com/mxml/2009;
xmlns:s=library://ns.adobe.com/flex/spark
xmlns:parametrosservice=services.parametrosservice.*
creationComplete=comboBox_creationCompleteHandler(event)
labelField=descripcion xmlns:valueObjects=valueObjects.*
fx:Script
![CDATA[
import mx.collections.ArrayCollection;
import mx.events.FlexEvent;
[Bindable]
public var dominio:int;
protected function
comboBox_creationCompleteHandler(event:FlexEvent):void
{
getParametrosResult.token =
parametrosService.getParametros(dominio);
}
//
http://www.forta.com/blog/index.cfm/2006/11/22/Flex-ComboBox-With-selectedValue-Support
public function BuscarParametroId(parametroId:int = 0):void
{
for (var i:int=0; i this.dataProvider.length - 1; i++)
{
if ( this.dataProvider[i].id == parametroId )
{
this.selectedIndex = i;
// this.dispatchEvent( new ListEvent(
ListEvent.CHANGE ) ) // since we are changing it we need to dispatch it
break;
}
}
}
]]
/fx:Script
fx:Declarations
s:CallResponder id=getParametrosResult/
parametrosservice:ParametrosService id=parametrosService
showBusyCursor=true/
valueObjects:Parametro id=parametroVO/
/fx:Declarations
s:AsyncListView list={getParametrosResult.lastResult}/
/s:ComboBox
FlashBuilder for PHP, versión 4.5
The load of the data in the combo was defined with the wizard.
The VO:
class Parametro
{
public $id;
public $dominio;
public $parametro;
public $descripcion;
public $abreviacion;
public $mascara_valor;
public $orden;
public $estado;
public $valor_equivalente;
public $valor_numerico;
public $usuario_creacion;
public $fecha_creacion;
public $usuario_modificacion;
public $fecha_modificacion;
The label is “descripción”. I’m passing the id to the combo to locate it in
the respective label.
Thanks.
Rodolfo.

[flexcoders] Re: background image with Flex?
There is no direct way to do this, at least in the 3.x SDK (we are still standardized on flex 3). However for a workaround try this: http://alekkus.com/blog/2009/02/flex-tutorial-setting-tile-image-as-background/ I use a modified version of this component for banners to create a repeating background with a movable right image that slides on top as the window is resized. --- In flexcoders@yahoogroups.com, markflex2007 markflex2007@... wrote: Basically a website background image is made to repeat itself seamlessly either horizontally or vertically or both. May I use a small image as background and let it repeat like web page? how to do that? Thanks Mark
[flexcoders] Using the restrict property for a textfield - \u is not working?
I am trying to set a numeric code range (versus entering string characters) for the restrict property of a text field. The documentation states that this can be achieved via the unicode escape sequence, such as \u0030-\u0039. But I cannot get this to work. Even trying single character such as mx:TextInput id=tt width=100% restrict=\u0030/ is failing. As I understand it, this should only allow the number 0 to be entered, but it does not work. Instead, I am able to enter 0, 3, and u, so the \u seems to be ignored. Am I missing something simple?
[flexcoders] Re: RTE when setting spark gridcolumn visible property (f
The column probably hasn't been created yet. Try the creationcomplete event of
the datagrid.
