capture selected value from mouseover

hi guys

i have a requirment where i have a label . when user puts the cursor on the label
a small window should popup and show the usernames from an ArrayCollection. When a username is clicked the clicked username should be passed to backend.

Here is the mxml

<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"
      xmlns:projectWork="org.view.projectWork.*"
      xmlns:projectNav="org.view.projectNav.*"
      creationComplete="init()"
      styleName="dashBoardPage"
      xmlns:services="services.*">

<mx:Script >
<![CDATA[
import org.entity.project.ProjectSummaryDTO;
[Bindable]
public var users:ArrayCollection; --> this collection has a list of usernames
public var selectedusername:String; -->holds the selected username

<mx:Label styleName="usernames" text="show users"/> --when user puts mouse here, a window should popup and show the usernames from 'users' Arraycollection

<mx:VBOX>

If 5 usernames are displayed in the box , when user clicks on a username i need to capture that username and pass it to the backend.
So i have created a string var 'selectedusername' which will contain the selected username.

Am i in the right direction?
Can anyone please help me with some code

thanks

Why you cannot user component List and show all 5 usernames as dataProvider
when user click on row you will listen itemClick event and set selectedusername - event.target.selectedItem;

by dataprovider do you mean datagrid? I dont want to use a datagrid. My boss wants a pop-up window when the mouse cursor is placed on the label. Is that possible?

thanks

Everything is possible just need to know what you want

<mx:Script>
            <![CDATA[
                  import mx.controls.Alert;
            ]]>
      </mx:Script>
      <mx:Label styleName="usernames" text="show users" mouseOver="Alert.show(event.target.text)"/>

Ok cool.. When I click on a username I need to pass the username to my
java backend. Any idea how I can do that?

Thanks for the help

dgofman

what services are you using? RemoteObject, WebService or HttpService?

using RemoteObject to call java methods. So i am basically passing the selected username
to the backend java method.

cool, thx very much

>><mx:Label text="Current Selected User is '{selectedUser}'" click="selectUser(event)"/>
Instead of click, i should be able to do 'mouseover' ,right ?

dgofman

you can assign any events for Label component. (focus, mouseOver, mouseDown, click etc..)

No user is function argument on the server side.
