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");

The TableItem you receive from getSelection contains every column and you
get the contents of each one with getText(int).
This is only a guess as I havent done this myself and I dont know why you
want the column contents anyway. The SWT table is remarkable low level and
your data should be stored in a model. Then you need a class which can
convert your model object to a string suitable for a table column and a
class to put these strings into the table. When a row is selected get the
index of the row and resolve it back to your domain object in your model.
I will abandon the Table in favor of TableViewer and hope it is easier to
manage.
