RE: [flexcoders] Re: broadcasting to a sub-component

Tue, 02 Aug 2005 07:47:40 -0700

The problem that I have is to refresh the values of a component which having many other children components.  I would like to trigger all RemoteObjects inside each component when the zoneID changed.
How to trigger the Child components?
 
Thanks

Why not have the zone id stored in a variable in your Application and then use binding to assign it through to your components?  When the selection changes simply update the value in the Application and everything will propagate through?  Make sure that you cast your application appropriately so everyone knows what's going on:  {NoeveauProject(Application.application).selectedZoneID}

 

You could also look into a concept like a ModelLocator that frameworks like Cairngorm suggest, but if you're really close this kind of technique should get you there.

In our apps, we would like to refresh all the values in all related
forms  based on a selected ID from a list. Each time we select a
zone ID, all the children components must change their values.  I
haven't figured out how to do so. Can you please help me...I feel that
I must use the Dispatching but I don't get it yet on how to trigger
a function in each component.

Here is the structure of the files.


NouveauProjet.mxml (this is the main apps)
<mx:Application......>

      <mx:ViewStack id="vsl">
            <EEfrm:zone_hallPEBC projectID="{projID}"
id="zone_hallPEBC" zoneGenID="{zoneGenID}" target="{this}"/>
            <EEfrm:zone_hallMainPEBC id="zone_hallMainPEBC"/>
      ....


zone_hallPEBC.mxml
<mx:VBox....>

      function accessZone(choixZone:Object){
            _global.tempZone = choixZone;
            target.vsl.selectedIndex = 35;
      }

      <mx:List id="zones" width="100%" height="100%"
dataProvider="{ecranRO.affichage.result}" labelField="Description"
borderStyle="solid"/>
      <mx:Button id="accederButton" label="Accéder à la zone"
click="must go to page and refresh all the values for all the
viewStacks"/>

zone_hallMainPEBC.mxml
<mx:VBox.....>

      function initApp(){
            ecranRO.affichage(_global.tempZone.Building_Zone_ID);
      }


.....
      <mx:RemoteObject id="ecranRO"...>
            <mx:method name="affichage" >
                  <mx:arguments>
                        <zoneID>{choixZone.ZoneID}</zoneID>
                  </mx:arguments>
            </mx:method>     
      </mx:RemoteObject>

<mx:Accordion id="myAccordion" width="100%" height="100%" >
      <mx:TabNavigator label="Enveloppe">
     
            <EEfrm:MursExtPEBCFrm id="MursExtPEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}" />
                <EEfrm:FenestrationPEBCFrm id="FenestrationPEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}"/>
            <EEfrm:ToiturePEBCFrm id="ToiturePEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}"/>

      </mx:TabNavigator>
      <mx:TabNavigator label="Équipements">
            <EEfrm:EclairagePEBCFrm id="EclairagePEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}" />
            <EEfrm:CuissonPEBCFrm id="CuissonPEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}"/>
            <EEfrm:EvacuaPEBCFrm id="EvacuaPEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}"/>
      </mx:TabNavigator>
      <EEfrm:CVCAPEBCFrm id="CVCAPEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}" label="CVCA"/>
      <EEfrm:RegulationPEBCFrm id="RegulationPEBCFrm"
zoneID="{_global.tempZone.Building_Zone_ID}" label="Régulation"/>
</mx:Accordion>

MursExtPEBCFrm & FenestrationPEBCFrm & ToiturePEBCFrm &
EclairagePEBCFrm & CuissonPEBCFrm & EvacuaPEBCFrm & CVCAPEBCFrm &
RegulationPEBCFrm

<VBox....>

      function initApp(){
            ecranRO.affichage(_global.tempZone.Building_Zone_ID);
      }

......      .

      <mx:RemoteObject id="ecranRO"...>
            <mx:method name="affichage" >
                  <mx:arguments>
                        <zoneID>{choixZone.ZoneID}</zoneID>
                  </mx:arguments>
            </mx:method>     
      </mx:RemoteObject>

<mx:TextInput text="{ecranRO.result.input1}">

.......


Thanks for any help.
