Hi.
Anybody can tell me the way to load all the files from a directory and show
them into a JTable. Which is the technique to do this?.
Thanks

Follow the trail to the TableModel

You can use QuickTable to implement the same feature in just three
statements

DBTable myFileTable = new DBTable();
File f = new File("C:\\temp\\");
myFileTable.refreshDataObjects(f.listFiles(), null);

You don't need to write any model.

QuickTable is a free java component (http://quicktable.org) which is an
implementation on top of JTable , but hides all the complexities and
allows to use the JTable methods. So you can just replace Jtable with
QuickTable.

Yes, but the problem is the same because "C:\\temp\\" must be variable, is
not constant, so when I select the directory from the JFileChooser it give
in this way "C:\temp\", at least using my code.

Thanks

Please refrain from top-posting, I find it most confusing

Well ..duhh. (We are all programmers here!)

Try this..

String s = "c:\temp";
System.out.println(s);
s = "c:\\temp";
System.out.println(s);

oK, RIGHT
THEN, why this doesn't work??

(dirLocal is a JLabel)
void btnSeleccionaDirectorio_actionPerformed(ActionEvent e) {
int retval;
JFileChooser chooser = new JFileChooser();
//chooser.DIRECTORIES_ONLY;
chooser.setDialogType(JFileChooser.OPEN_DIALOG);
chooser.setDialogTitle("Select directory??");
chooser.setMultiSelectionEnabled(false);
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
if (chooser.showDialog(this, "Select") !=
JFileChooser.APPROVE_OPTION) {
System.exit(1);
}
dirLocal.setText("Local Directory: " +
chooser.getSelectedFile().getAbsolutePath());

model.setColumnCount(0);
model.setRowCount(0);

int columns = 2;
model.addColumn("Fichero");
model.addColumn("Estado");

loadTable(dirLocal.getText());

}
void loadTable(String dirLocal) {
File myFile = new File(dirLocal);
File[] allFiles = myFile.listFiles();
int i, j, k;
System.out.println("Directory: " + dirLocal);
k = 0;
for (i = 0; i < allFiles.length; i++) {
if (allFiles[i].isFile()) {
j = (new Long(allFiles[i].length())).intValue();
if (j <= MAX_TAM) {
Vector row = new Vector(2);
row.addElement(allFiles[i]);
row.addElement(new Integer(3));
model.insertRow(k++, row);
}
}
}

Greetings

(shrugs) Maybe it is just lazy.

What Andrew was trying to tell you is:
"Look at some of the error messages given by your compiler and figure it
out from there."
The compiler is even kind enough to tell you what type of error[s] you
made and approximately where on which line they are.
HTH.

Hi.
There is only one error because my var is "c:\temp" and the vector
created is null son allFiles.length give me an exception, BUT if I put
"C:\\temp" it create the vector with the files correctly.

So. Only I want the way to obtain an absolute path in the form "C:\\temp".

anyway, thanks for your reply
