Hi Craig,
I think the following does what you want. It's based on
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet88.java?rev=HEAD&a mp;content-type=text/vnd.viewcvs-markup .
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
final Table table = new Table(shell, SWT.FULL_SELECTION |
SWT.HIDE_SELECTION);
table.setLinesVisible(true);
TableColumn column = new TableColumn(table, SWT.NONE);
for (int i = 0; i < 10; i++) {
TableItem item = new TableItem(table, SWT.NONE);
item.setText("item " + i);
}
final TableEditor editor = new TableEditor(table);
editor.horizontalAlignment = SWT.LEFT;
editor.grabHorizontal = true;
editor.minimumWidth = 50;
final int EDITABLECOLUMN = 0;
table.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
Control oldEditor = editor.getEditor();
if (oldEditor != null) oldEditor.dispose();
TableItem item = (TableItem)e.item;
if (item == null) return;
Text newEditor = new Text(table, SWT.NONE);
newEditor.setText(item.getText(EDITABLECOLUMN));
newEditor.addModifyListener(new ModifyListener() {
public void modifyText(ModifyEvent e) {
Text text = (Text)editor.getEditor();
editor.getItem().setText(EDITABLECOLUMN,
text.getText());
}
});
newEditor.selectAll();
newEditor.setFocus();
editor.setEditor(newEditor, item, EDITABLECOLUMN);
}
});
shell.setSize(300, 300);
table.setBounds(10,10,200,200);
column.setWidth(table.getSize().x); // <--
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}

I was able to apply the concept to my code and it works perfectly. Thanks.

I was experimenting with different values for those two, and
nothing made any difference, even commenting them out.
I think I've figured it out: (at least for win32) you only
get an editor wider than the column if there is extra table
width to the right of the column. Craig wants a virtual
editable List, where the table appears to have exactly one
column, so this will never happen, and setting minimumWidth
is pointless. Without this, grabHorizontal = true fits the
editor to the column, and setting horizontalAlignment is
also pointless.
If you leave these fields alone and add
table.addControlListener(new ControlAdapter() {
public void controlResized(ControlEvent e) {
column.setWidth(table.getClientArea().width);
}
});
the gizmo is resizable in x and y, and looks like an editable
list whatever:
public static void main(String[] args) {
Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout( new FillLayout());
final Table table = new Table(shell, SWT.FULL_SELECTION | SWT.HIDE_SELECTION);
table.setLinesVisible(true);
final TableColumn column = new TableColumn(table, SWT.NONE);
for (int i = 0; i < 10; i++) {
TableItem item = new TableItem(table, SWT.NONE);
item.setText("item " + i);
}
final TableEditor editor = new TableEditor(table);
editor.grabHorizontal = true;
final int EDITABLECOLUMN = 0;
table.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
Control oldEditor = editor.getEditor();
if (oldEditor != null)
oldEditor.dispose();
TableItem item = (TableItem) e.item;
if (item == null)
return;
Text newEditor = new Text(table, SWT.NONE);
newEditor.setText(item.getText(EDITABLECOLUMN));
newEditor.addModifyListener(new ModifyListener() {
public void modifyText(ModifyEvent e) {
Text text = (Text) editor.getEditor();
editor.getItem().setText(EDITABLECOLUMN, text.getText());
}
});
newEditor.selectAll();
newEditor.setFocus();
editor.setEditor(newEditor, item, EDITABLECOLUMN);
}
});
table.addControlListener(new ControlAdapter() {
public void controlResized(ControlEvent e) {
column.setWidth(table.getClientArea().width);
}
});
shell.setSize(300, 300);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}

Paul hit on exactly the implementation I came up with. The "concept"
that I pulled from Grant's example was setting the width of the column
directly rather than using TableLayout. It seemed that even if I told
the TableLayout to use all of the space, it never really did. I hadn't
realized that I wasn't seeing an extra column, but I was seeing the
extra space the single column wasn't filling.
What is the difference between getClientArea() and getSize()? I used
getSize() in my case and it seemed to work correctly.

Calling getClientArea does not include scrollbars or borders. Calling
getSize gives the outside size of the table.
