I have used SWT for a long time now.
Today, we encountered a problem we have never seen before.
We are using a simple SQL statement to build a table. The problem is
that only the first column is actually filled with data.
Does anybody know why? I am using Eclipse 3.0.0.
Here is the code:
Table table;
table = new Table(shell, SWT.BORDER);
table.setBounds(10, 15, 845, 370);
table.setLinesVisible(true);
table.setHeaderVisible(true);
fillBaseTable();
final TableColumn v_nr = new TableColumn(table, SWT.NONE);
v_nr.setWidth(39);
v_nr.setText("Nr.");
final TableColumn v_datum = new TableColumn(table, SWT.NONE);
v_datum.setWidth(91);
v_datum.setText("Datum");
final TableColumn v_beleg = new TableColumn(table, SWT.NONE);
v_beleg.setWidth(77);
v_beleg.setText("BelegNr");
final TableColumn v_soll = new TableColumn(table, SWT.NONE);
v_soll.setWidth(70);
v_soll.setText("Soll");
final TableColumn v_haben = new TableColumn(table, SWT.NONE);
v_haben.setWidth(70);
v_haben.setText("Haben");
final TableColumn v_betrag = new TableColumn(table, SWT.NONE);
v_betrag.setWidth(80);
v_betrag.setText("Betrag");
final TableColumn v_ust = new TableColumn(table, SWT.NONE);
v_ust.setWidth(137);
v_ust.setText("Ust.");
final TableColumn v_text = new TableColumn(table, SWT.NONE);
v_text.setWidth(100);
v_text.setText("Text");
public void fillBaseTable()
{
String sql = "SELECT id, tstamp::text, belegnt, sollbuch,
habenbuch, betrag, beschreibung "
+ " FROM t_buchung "
+ " ORDER BY id, tstamp, sollbuch, habenbuch ";
try
{
table.removeAll();
Statement stmt = Config.conn.createStatement();
ResultSet res = stmt.executeQuery(sql);
while (res.next())
{
TableItem it = new TableItem(table, SWT.NONE);
it.setText(0, "" + res.getString(1));
it.setText(1, "" + res.getString(2));
it.setText(2, "" + res.getString(3));
it.setText(3, "" + res.getString(4));
it.setText(4, "" + res.getString(5));
it.setText(5, "");
it.setText(6, "" + res.getString(6));
it.setText(7, "" + res.getString(7));
}
}
catch (Exception e)
{
MessageBox box = new MessageBox(new Shell());
box.setMessage("kann buchungen nicht abfragen: "
+ e.getMessage());
box.open();
}
}
My SQL statement returns the right data. Also, res.getString(*) contains
the right data (I have checked that with temporary data). Still, only
the first column will contain data - all other columns are blank.
There is no exception thrown.
Is it a bug?
By the way: I have just a small application so people can see the entire
code.

I'm not an expert but with some quick code I whipped up it appears that
when adding TableItems before adding the TableColumns it displays this
behavior on windows. Move your fillBaseTable() call after the creation
of the TableColumns and see if it works.

You need to create the TableColumn objects before calling fillBaseTable().
If you set text into a table item for a column that does not exist, it is
ignored.

If there really is a platform difference between Windows and where ever else
you are running, please enter a bug report.
