Hi
of course: here you have:
--------// JTableViewer.java //---------------
package sample.jtable;
import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.Panel;
import java.util.List;
import javax.swing.JComponent;
import javax.swing.JRootPane;
import org.eclipse.jface.viewers.StructuredViewer;
import org.eclipse.swt.SWT;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Widget;
public class JTableViewer extends StructuredViewer {
private Control control;
public JTableViewer(Composite parent, int style, JComponent component) {
super();
Control composite = new Composite(parent, SWT.NO_BACKGROUND
| SWT.EMBEDDED);
Frame frame = SWT_AWT.new_Frame((Composite) composite);
Panel panel = new Panel(new BorderLayout()) {
private static final long serialVersionUID = -5327043823430217452L;
public void update(java.awt.Graphics g) {
paint(g);
}
};
frame.add(panel);
JRootPane root = new JRootPane();
panel.add(root);
java.awt.Container contentPane = root.getContentPane();
contentPane.add(component);
control = composite;
}
public Control getControl() {
return control;
}
protected Widget doFindInputItem(Object element) {
return null;
}
protected Widget doFindItem(Object element) {
return null;
}
protected void doUpdateItem(Widget item, Object element, boolean fullMap)
{
}
protected List getSelectionFromWidget() {
return null;
}
protected void internalRefresh(Object element) {
}
public void reveal(Object element) {
}
protected void setSelectionToWidget(List l, boolean reveal) {
}
}
----------------// JTableViewPart.java //-------
package sample.jtable;
import ilog.views.util.swt.IlvEventThreadUtil;
import javax.swing.JTable;
import org.eclipse.jface.util.LocalSelectionTransfer;
import org.eclipse.swt.SWT;

public class JTableViewPart extends ViewPart {
public static final String ID = JTableViewPart.class.getName();
private JTableViewer viewer;
static {
IlvEventThreadUtil.enableAWTThreadRedirect();
}
public void createPartControl(Composite parent) {
String[] columnNames = { "First Name", "Last Name", "Sport",
"# of Years", "Vegetarian" };
Object[][] data = {
{ "Mary", "Campione", "Snowboarding", new Integer(5),
new Boolean(false) },
{ "Alison", "Huml", "Rowing", new Integer(3), new Boolean(true) },
{ "Kathy", "Walrath", "Knitting", new Integer(2),
new Boolean(false) },
{ "Sharon", "Zakhour", "Speed reading", new Integer(20),
new Boolean(true) },
{ "Philip", "Milne", "Pool", new Integer(10),
new Boolean(false) } };
JTable table = new JTable(data, columnNames);
viewer = new JTableViewer(parent, SWT.NONE, table);
int ops = DND.DROP_COPY | DND.DROP_MOVE;
Transfer[] transfers = new Transfer[] { LocalSelectionTransfer
.getTransfer() };
viewer.addDropSupport(ops, transfers, new JTableDropAdapater(viewer));
}
public void setFocus() {
viewer.getControl().setFocus();
}
}
--------------// JTableDropAdapter.java //-----------
package sample.jtable;
import org.eclipse.jface.viewers.Viewer;
import org.eclipse.jface.viewers.ViewerDropAdapter;
import org.eclipse.swt.dnd.DropTargetEvent;
import org.eclipse.swt.dnd.TransferData;
public class JTableDropAdapater extends ViewerDropAdapter {
protected JTableDropAdapater(Viewer viewer) {
super(viewer);
}
public boolean performDrop(Object data) {
return true;
}
public boolean validateDrop(Object target, int operation,
TransferData transferType) {
return true;
}
public void dragEnter(DropTargetEvent event) {
super.dragEnter(event);
System.out.println("ScheduleDropAdapater.dragEnter called");
}
public void dragLeave(DropTargetEvent event) {
super.dragLeave(event);
System.out.println("ScheduleDropAdapater.dragLeave called");
}
public void dragOver(DropTargetEvent event) {
super.dragOver(event);
System.out.println("ScheduleDropAdapater.dragOver called");
}
}
I hope this clarifies a bit my request.
Thanks for your efforts.

Hi,
I hope I can wrap my head around this problem on the weekend but I don't
think that I can be of big help the times I did Swing programming are a
long time ago. The only thing I can suggest to you is to use real
SWT-Controls and not Swing components.
I'm sure there's a reason that you are using Swing inside SWT but maybe
you should reajust your decision and use JFace-TableViewer which build
upon a real SWT-Table or if this widget set is not rich enough checkout
the controls from Nebula which will get JFace-Viewer support after M5 is
out.
Why are you using Swing?

Hi,
You can also try to ask at the SWT-Newsgroup because this all sounds
like a bug in SWT and it's SWT_AWT-Bridge.
Fileing bugs isn't really a problem. Go to
https://bugs.eclipse.org/bugs/ and register an account, then file the
bug against Component SWT on
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform
One more thing I'm not sure I understand is why you wrap up your JTable
with a StructuredViewer what's the purpose of this, don't get me wrong
you can easily do all this but what's the profit of it. Swing-Components
are already MVC based and there's no need to but one more MVC-layer
above it.
