setData in ListGrid in SmartGWT

Question

Hi i am trying to use SmartGWT.

I have Arraylist

ArrayList<FileDocument> documentsArrayList = new ArrayList<FileDocument>();

// all the value are in the documentsArrayList

and a table

private ListGrid getDocumentTable() {
        if (documentTable == null) {
            documentTable = new ListGrid();
            documentTable.setSize("644px", "379px");
            documentTable.setCanResizeFields(true);

            documentTable.setFields(getStatus(),getIcon(),getName(),getSize(),getModifiedby(),getModifiedDate());
        }
        return documentTable;
    }

fields of the grid are like

public ListGridField getName() {
        if (name == null) {
            name = new ListGridField("name","Name");
        }
        return name;
    }

I want to put values to array list value to table.

documentTable.setData(some list grid record);

How to convert ArrayList in ListGridRecord so that i can set the data.

Answer 1

You need to create a method which will accpet your ArrayList as an input and return an array of ListGridRecord which in turn can be set using listGrid.setData(ListGridRecord[] records);

Kick off Example:

 listGrid.setData(getListridRecords(employees)); // set records here 

 private void getListGridRecords(ArrayList employees) {
      ListGridRecords records[]=null;
      if(employees!=null){
       records = new ListGridRecord[employees.size()];
       for(int cntr=;cntr<employees.size();cntr++){
        ListGridRecord record = new ListGridRecord();   
        Employee emp = employees.get(cntr);
        record.setAttribute("name",emp.getName()); //your ListGridField 's name
        record.setAttribute("status",emp.getStatus()); //your ListGridField 's name
        //.. more goes here
        records[cntr] = record;
      }

   }
   return records;
}

Another way could be this

You can also use the class

A Array list can be converted into a recordList that can be added to the setData method of the ListGridField. Below is the code snippet of the implemention.

`RecordList recordList = new RecordList();
 for(DocumentsArrayList documentsArray: documentsArrayList)
 {
  Record record = new Record();
  record.setAttribute("Name", getName());
  record.setAttribute("size", getSize());
  record.setAttribute("user", getuser());
  recordList.add(record);
 }          
 documentTable.setData(recordList);
 }

` All the attribute name should match the values in the POJO so that the value object can be directly used.
