Hello everybody,
I have just started working with Tables. I've started
with the snippets available at eclipse.org and
everything was ok.
In my application I want to put a Table inside a
Composite and it just doesn't work. I'm using Windows
XP and eclipse 3.0.2. Here is the code that I've
changed from Snippet103:
Thank you
import org.eclipse.swt.*;
public class TableTest {
static char content = 'a';
public static void main(String[] args) {
final Display display = new Display();
Shell shell = new Shell(display);
shell.setBounds(10, 10, 200, 240);
/* This is what I've added */
Composite c = new Composite(shell, SWT.NONE);
FillLayout f = new FillLayout();
c.setLayout(f);
/* Now I create the table with a composite instead
of using a Shell */
Table table = new Table(c, SWT.BORDER);
table.setBounds(10, 10, 160, 160);
final TableItem[] items = new TableItem[4];
for (int i = 0; i < 4; i++) {
new TableColumn(table, SWT.NONE).setWidth(40);
}
for (int i = 0; i < 4; i++) {
items[i] = new TableItem(table, SWT.NONE);
populateItem(items[i]);
}
Button button = new Button(shell, SWT.PUSH);
button.setBounds(10, 180, 50, 30);
button.setText("Change");
button.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
for (int i = 0; i < 4; i++) {
populateItem(items[i]);
}
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
static void populateItem(TableItem item) {
String stringContent = String.valueOf(content);
item.setText(new String[] { stringContent,
stringContent, stringContent, stringContent });
content++;
if (content > 'z')
content = 'a';
}
}

Hi,
Try to set a layout on your shell.

Thanks a million.
That was it. Somehow, if the Shell doesn't have a layout and if you put a
Table inside a composite in a Shell, the Table does not show, even if the
Composite has a Layout.
