Return Row Value when Clicking Outputlink

I have a table and a controller 
<apex:page sidebar="false" controller="DisplayStatus">
          <apex:pageBlock title="Gadget (Gadget__c)">
             <apex:pageBlockTable value="{!gadgetlist}" var="gadget">
                 <apex:column headerValue="Gadget" value="{!gadget.Name}"/>
                 <apex:column headerValue="Action">
                       <apex:outputlink>Edit</apex:outputlink>
                 </apex:column>
             </apex:pageBlockTable>
         </apex:pageBlock> 
</apex>
If I click Edit it will return the value of its corresponding row (gadget.Name) in a System.debug.
ex.

Gadget                     Action

Smartphone               Edit
Watch                       Edit
Camera                     Edit

If I click Edit in the 2nd row, I would return Smartphone in a System.Debug statement.
How could I do this?

Hello Seraph,

Try following code
  
<apex:page sidebar="false" controller="DisplayStatus">
          <apex:pageBlock title="Gadget (Gadget__c)">
             <apex:pageBlockTable value="{!gadgetlist}" var="gadget">
                 <apex:column headerValue="Gadget" value="{!gadget.Name}"/>
                 <apex:column headerValue="Action">
                       <apex:commandLink value="Edit" action="{!showGadget}">
                                    <apex:param name="gadgetName"  value="{!gadget.Name}" />
                       </apex:commandLink>
                 </apex:column>
             </apex:pageBlockTable>
         </apex:pageBlock> 
</apex>

and you can get the Gadget Name at controller using following code:
  
public class DisplayStatus{

       public void showGadget(){
          String strGadgetName = ApexPages.currentPage().getParameters().get('gadgetName');
           System.debug(strGadgetName);
        }
}

If its helps, please mark as best answer so it will help to other who will serve same problem.
