The following code works with a single click. How do I modify it so my
listener only executes when a single table cell has been double clicked?
I tried adding a MouseListener but that will only give me coordinates and
not the contents of the table cell. If I have coordinates, how do I get the
table cell contents?
Thanks,
Siegfried
table = new Table(this, SWT.SINGLE | SWT.BORDER | SWT.FULL_SELECTION);
data = new FormData();
data.top = new FormAttachment(0, 0);
data.bottom = new FormAttachment(100, 0);
data.left = new FormAttachment(sash, 0);
data.right = new FormAttachment(100, 0);
table.setLayoutData(data);
table.setHeaderVisible(true);
table.setLinesVisible(true);
table.addSelectionListener(new SelectionAdapter(){
public void widgetSelected(SelectionEvent event){
if(table.getSelectionCount()==1){
TableItem item =table.getSelection()[0];
String urlTarget = item.getText();
}
}
});
new TableColumn(table, 0).setText("Name");
new TableColumn(table, 1).setText("Value");
new TableColumn(table, 2).setText("Text");

Ricky,
That worked! Now, why is it that getSelection returns me an array of 1? I
can only get the contents of the first column! How do I get the second
column?
Thanks,
Siegfried
