ApexPages.StandardSetController Passing in List Variable?

I'm getting the error "Constructor not defined: [ApexPages.StandardSetController].<Constructor>(List<StoreFront2.DisplayMerchandise). I want to pass in the list of Products I've constructed in the List<DisplayMerchandise> products; variable. How can I accomplish this? Or is there a better way to code this?  Thanks.
  
public class StoreFront2{

List<DisplayMerchandise> products;


public StoreFront2(){
        ct=new Purchase_Line_Items__c();
        ct2=new Contact();
        flag = false;
        flip = false;
        flag2 = true; 
      
         
    }

public ApexPages.StandardSetController samplePagination{
        get{
            if(samplePagination == null){
                samplePagination = new ApexPages.StandardSetController(products);
                samplePagination.setPageSize(5);
            }
            return samplePagination;
        }
        set;
        
    }

    public class DisplayMerchandise {
        public Merchandise__c merchandise{get; set;}
        public Decimal count{get; set;}
        public Decimal tempCount{get;set;}
        public DisplayMerchandise(Merchandise__c item){
            this.merchandise = item;
            
        }
    }

   public List<DisplayMerchandise> getProducts() {
        if (products == null){
            products = new List<DisplayMerchandise>();
    
            for (Merchandise__c item :
            [SELECT id, name, description__c, price__c
            FROM Merchandise__c
            WHERE Total_Inventory__c > 0]) {
           
            products.add(new DisplayMerchandise(item));
            }
        }
        return products;
    }
}

Hi Tyler,

As per per "standardsetcontroller" You can instantiate a StandardSetController in either of the following ways :-
From a list of sObjects 
List<account> accountList = [SELECT Name FROM Account LIMIT 20];
ApexPages.StandardSetController ssc = new ApexPages.StandardSetController(accountList);
From a query locator 
ApexPages.StandardSetController ssc = 
new ApexPages.StandardSetController(Database.getQueryLocator([SELECT Name,CloseDate FROM Opportunity]));

Problem in your code.

You are trying to pass list of wrapper classes not sobject. If you will pass below list it will work 
List<Merchandise__c> ListItem =   [SELECT id, name, description__c, price__c FROM Merchandise__c WHERE Total_Inventory__c > 0] ;
ApexPages.StandardSetController ssc = new ApexPages.StandardSetController(ListItem);
Or please check below post how to perform pagination on Wrapper class

Hi Tyler,

Replace your method code with the below code. 
public List<DisplayMerchandise> getProducts() {
        if (products == null){
            products = (List<DisplayMerchandise>)samplePagination.getRecords();
            }
        }
        return products;
    }

Please let me know if you get the same issue.

Thanks,
Naval

Hi Tyler, 

Replace your method code with the below code.
  
public ApexPages.StandardSetController samplePagination{
        get{
            if(samplePagination == null){
                List<Merchandise__c> Merchandiselist=[SELECT id, name, description__c, price__c 
                                                                            FROM Merchandise__c 
                                                                            WHERE Total_Inventory__c > 0];
                samplePagination = new ApexPages.StandardSetController(Merchandiselist);
                samplePagination.setPageSize(5);
            }
            return samplePagination;
        }
        set;        
    }
  
public List<DisplayMerchandise> getProducts() {
        if (products == null){
            products = new List<DisplayMerchandise>();
            for (Merchandise__c item :(List<Merchandise__c>)samplePagination.getRecords()   ) {           
                products.add(new DisplayMerchandise(item));
            }
        }
        return products;
    }

this is will surely work for you. 
if you want to do some navigation on record set , Example  
  
<apex:commandButton status="" reRender="" value="Next" action="{!next}" disabled="{!!hasNext}" title="Next Page" />

public void next() {
        setCon.next();
            // do you operation here 
 }

so that you can get next record as well you can perform your pration too.
