    public ApexPages.StandardSetController setCon {
        get{
            if(setCon == null){
                size = 5;
                setCon = new ApexPages.StandardSetController(Database.getQueryLocator([SELECT id,LineNumber,PriceBookEntry.Product2Id, PriceBookEntry.Product2.Name,Product2Id,Quantity,unitprice,QuoteId FROM quoteLineItem]));
                setCon.setPageSize(size);
                noOfRecords = setCon.getResultSize();
            }
            return setCon;
        }set;
    }
     
    Public List<SelectedWrapper> getLineitems(){
        categories = new List<SelectedWrapper>();
        for (quoteLineItem category : (List<quoteLineItem>)setCon.getRecords())
            categories.add(new SelectedWrapper(category));

        return categories;
    }    
public PageReference Yourmethod() {        
System.debug('Hi! Welcome');
refresh();

        return null;
    }
     
    public Boolean hasNext {
        get {
            return setCon.getHasNext();
        }
        set;

            quotelineiteobj = olineitem;
            checked = false;
        }
    }
}

Step 2:- Create a Visualforce page with help of below code.

<apex:page controller="ClassWithStandardSetController" sidebar="false">
    <apex:form >

        width: 100%;
        height: 100%;
        z-index: 1004;
        left: 0%;
        top: 0%;
        
        }
   </style>
        
      <apex:actionStatus id="statusProcessing" startStyleClass="Processing"/>
        <apex:outputPanel id="Msg">
            <apex:pagemessages ></apex:pagemessages>
            
        </apex:outputPanel>
       <apex:pageBlock title="{!$ObjectType.quoteLineItem.LabelPlural} Page #{!pageNumber}">

         <apex:pageBlockButtons rendered="{!if(Lineitems.size>0, true, false)}" >
                <apex:commandButton value="Your method" action="{!Yourmethod}" rerender="table,Msg" status="statusProcessing" />
            </apex:pageBlockButtons>
        <apex:pageMessage severity="error"  summary="There is no Quote Line Items." rendered="{!if(Lineitems.size==0, true, false)}"></apex:pageMessage>
        <apex:pageBlockTable value="{!Lineitems}" var="c" title="{!$ObjectType.quoteLineItem.LabelPlural}" id="table" rendered="{!if(Lineitems.size>0, true, false)}">
          <apex:column width="25px">
            <apex:inputCheckbox value="{!c.checked}"/>
          </apex:column>
          <apex:column value="{!c.quotelineiteobj.PriceBookEntry.Product2.Name}" headerValue="Name"/>
          <apex:column headerValue="{!$ObjectType.Product2.LabelPlural}" value="{!c.quotelineiteobj.PriceBookEntry.Product2.Name}"/>
            <apex:column value="{!c.quotelineiteobj.QuoteId }" />            
            <apex:column value="{!c.quotelineiteobj.Quantity}" />
            <apex:column value="{!c.quotelineiteobj.unitprice}" />
        </apex:pageBlockTable>
    </apex:pageBlock>

    <apex:panelGrid columns="4" >
    <apex:commandLink action="{!first}">First</apex:commandlink>
    <apex:commandLink action="{!previous}" rendered="{!hasPrevious}">Previous</apex:commandlink>
    <apex:commandLink action="{!next}" rendered="{!hasNext}">Next</apex:commandlink>
