local FileTableModel
Hey i have a "problem" with mine FileTableModel. I get al the values in my JTable but there isn't a ".." directory in the JTable. So i want to create a row with the option to go 1 directory up. How do i do that?
dir =new File("C:\\java");
FileTableModel model =new FileTableModel(dir);
TableSorter sorter1 =new TableSorter(model);
table =new JTable(sorter1);
sorter1.setTableHeader(table.getTableHeader());
sorter1.setSortingStatus(0, -1);
TableColumn column =null;
for (int i = 0; i < 3; i++){
column = table.getColumnModel().getColumn(i);
if (i == 0){
column.setPreferredWidth(20);
}else{
if (i == 1){
column.setPreferredWidth(160);
}
else
{
column.setPreferredWidth(80);
}
}
}
ListSelectionModel listMod1 = table.getSelectionModel();
listMod1.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
listMod1.addListSelectionListener(this);
table.addMouseListener(this);
tLocal.setText(dir.getPath());
table.getTableHeader().setReorderingAllowed(false);
table.setRowHeight(20);
scrClient =new JScrollPane(table);
The filetable is created with this code:
class FileTableModelextends AbstractTableModel{
protected File dir;
protected String[] filenames;
protected String[] columnNames =new String[]{
"","name","size","last modified","directory?","readable?","writable?"
};
protected Class[] columnClasses =new Class[]{
Icon.class,String.class, Long.class, Date.class,
Boolean.class, Boolean.class, Boolean.class
};
// This table model works for any one given directory
public FileTableModel(File dir){
this.dir = dir;
this.filenames = dir.list();// Store a list of files in the directory
}
// These are easy methods
publicint getColumnCount(){return 3;}// A constant for this model
publicint getRowCount(){return filenames.length;}// # of files in dir
// Information about each column
public String getColumnName(int col){return columnNames[col];}
public Class getColumnClass(int col){return columnClasses[col];}
// The method that must actually return the value of each cell
public Object getValueAt(int row,int col){
File f =new File(dir, filenames[row]);
switch(col){
case 0:return f.isDirectory() ? folder : files;
case 1:return filenames[row];
case 2:if (f.isDirectory()==true){
returnnull;
}else{
returnnew Long(f.length());
}
case 3:return f.isDirectory() ? Boolean.TRUE : Boolean.FALSE;
case 4:return f.canRead() ? Boolean.TRUE : Boolean.FALSE;
case 5:return f.canWrite() ? Boolean.TRUE : Boolean.FALSE;
default:returnnull;
}
}
}
