[groovy-user] how to clear all rows in a jtable ?

[citron]

How can I clear all rows in a jTable with groovy?


This throws a class cast exception
((DefaultTableModel)table.getModel()).setNumRows(0);

Exception in thread "AWT-EventQueue-0"
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast
object 'groovy.model.DefaultTableModel@1bd19f4' with class
'groovy.model.DefaultTableModel' to class

Set num rows is marked as obsolete in the Java documentation (since 1.3)

http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html#setNumRows(int)

Have you tried what it suggests, and use setRowCount instead?

table.model.rowCount = 0

Just install a new, empty, model with JTable's setModel()?

Ian.

[Tim Yates]

Actually, ignore me

The first exception shows it's a groovy.model.DefaultTableModel, not a javax.swing.table.DefaultTableModel

So rowCount doesn't exist

I'd try Ian's suggestion

Tim

[Anders Viklund]

javax.swing.table.DefaultTableModel.getRowCount()                      exists
groovy.model.DefaultTableModel.getRowCount()                           exists

javax.swing.table.DefaultTableModel.setRowCount(int rowCount)     exists
groovy.model.DefaultTableModel.setRowCount(int rowCount)          does NOT exist, why?

Ian,

how would you change this code according your suggestion?

def swing = new SwingBuilder()
def tableData
def jtable

jtable = table(){
                           tableModel( list:tableData){
                                propertyColumn( header:"File", propertyName:"file", cellRenderer: new CustomTableCellRenderer(),editable: false )
                                propertyColumn( header:"Line", propertyName:"line", cellRenderer: new CustomTableCellRenderer(),preferredWidth:1,editable: false )
                                propertyColumn( header:"Date", propertyName:"date", cellRenderer: new CustomTableCellRenderer(),editable: false)
                                propertyColumn( header:"Location", propertyName:"location", cellRenderer: new CustomTableCellRenderer(),preferredWidth:5,editable: false )
                                propertyColumn( header:"Process", propertyName:"process", cellRenderer: new CustomTableCellRenderer(),editable: false)
                                propertyColumn( header:"ConversationId", propertyName:"conversationid", cellRenderer: new CustomTableCellRenderer(),editable: false)
                                propertyColumn( header:"Status", propertyName:"status", cellRenderer: new CustomTableCellRenderer(),editable: false)
                               
                           }  
                     }

...// Add row to table
def rows = jtable.getModel().getRowsModel().getValue()
def rowsModel = jtable.getModel().getRowsModel()
rows.add( [ file: file_, line:line_,date: date_,location:location_,process: process_,conversationid: conversationid_,status:status_ ] )
jtable.getModel().getRowsModel().setValue( rows )
jtable.getModel().fireTableDataChanged()
..

// Delete rows from table ??
...

Problem solved!

As usual, the solution is very simple with Groovy.


jtable.model.getRows().clear()
jtable.getModel().fireTableDataChanged()
