RE: [flexcoders] createChild and destroyChild
I think that if statement should be
if (counter 0)
{
this.destroyChild(rowArray[counter-1]);
counter--;
}

Subject: [flexcoders] createChild and destroyChild
I am new to FLEX and am working on an app that allows the user to
dynamically create a FormItem w/ various text boxes dynamically from
a click event including a delete button in each form item that will
allow the user to delete that specific instance of the object. I am
able to create the FormItem using createChild, but don't know how to
get destroyChild to work for a specific object. I am guessing you
must reference this when referring to the specific FormItem object,
but not sure of the correct syntax.
Note: In my code my add function calls a component I have created
(Start_New_Event.Components.Entry)
Here is what I have:
***
Main.mxml
**
?xml version=1.0?
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml;
mx:Script
![CDATA[
var rowArray : Object = new Array() ;
var counter : Number = 0 ;
private function addRow():Void
{
rowArray[counter] = Start_New_Event.Components.Entry
(formItem.createChild(Start_New_Event.Components.Entry, undefined,
null ) );
counter++;
}
public function deleteRow():Void{ //-- this function does not work
if(rowArray[counter] != 0){
this.destroyChild(rowArray[counter -1] );
counter--;
}
}
]]
/mx:Script
mx:Form
mx:Button label=Add width=60 click=addRow();/
mx:FormItem textAlign=left id=formItem
mx:HBox
mx:TextInput id=txtRCAParticipants width=150/
mx:TextInput id=txtTitle width=150/
mx:Button label=Delete click=deleteRow(); /
/mx:HBox
/mx:FormItem
/mx:Form
/mx:Application

RE: [flexcoders] createChild with custom components
Hi,
If your component class extends from mx.core.View or any of its
subclasses (container class) like Box, HBox, VBox etc, your component
would have this method automatically.
Following is custom mxml component, which extends form Hbox and you can
call createChild(..) on its intstances. For example, see the code below.
1) ##HBoxEx.mxml##
mx:Hbox xmlns:mx=http://www.macromedia.com/2003/mxml;
//your code
/mx:HBox
2) ##testHBoxEx.mxml##
mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml;
xmlns=*
mx:Script
function onHBoxInit()
{
_hb.createChild(mx.controls.Label, ,
{text:Hello World!});
}
/mx:Script
local:HBoxEx id=_hb /
/mx:Application
Hope that helps..

hi there, a rookie needs some help ;)
My Goal is to create custom Components dynamicly. Its no problem to
generate components with createChild(), but i dont know how to adress
custom components and what has to be imported in actionscript first.
tnx for your help..

Thanks for thatthat makes moving forward with more apps in the future easier to handle. Much appreciated Robert L. Brueckmann Web Developer Merlin Securities,LLC
RE: [flexcoders] createChild
Manish, I implemented the creationPolicy=auto and my tab navigator is still creating all of the children at load time. Like I said, I have an empty Tab navigator in the MXML code itselfwhen the user logs in, I trigger a GetUserApplications event which calls the command class, triggers the delegate class method which returns to the Application component view an array of strings listing all the apps the user has access to which I immediately loop through and create the associated tabs on the navigator and the corresponding components for each tabIm guessing the creation policy setting doesnt apply to children dynamically attached to the navigator component? If I had the components actually listed in the MXML file, this works but Im doing this on the fly because one user may only have access to app #1 and #2 whereas another may have all-accessso I need to do this dynamically and it works and my code I had written before your post about deferred instatiation built into the tab navigator still does the trick in the meantime. Thanks again, Rob Robert L. Brueckmann Web Developer Merlin Securities,LLC
