Hello,

I wanted to sort my table column through a double click on it. I don't
have a good idea how I can do it. I can set a viewer sorter on my table
viewer. It is the right way?

Thanks,
kristin

the SWT snippets [1] contain examples on how to sort a Table. See for
instance "sort a table by column".

Hope this helps,
Ralf

Hi Ralf,

Thanks, it was helpfully. But I have yet another problem. I can select a
line in my table viewer (tableViewer view) and see the information of the
selected line in another view (detail view) and in a new structure. If I
sort my table up and down, I can select a line in my table viewer but the
selection don't identify of my detail view.
I have a selectionProvider in my tableViewer view and a selectionListener
in my detail view. The tableColumns have a listener for the sort.
Can I don't have multiple listener? Do you have a idea what the problem
is?

Thanks,
kristin

I'm afraid I don't understand this. What do you mean by "the selection
don't identify of my detail view"?

Do you use the Workbench selection service? If so, maybe this article
could help:

Hello,

The selection listener of my detail view have no selection in my table
view when I have a selected line after the sort in my table view. The
listener don't reacts of the selection.

Hello,

It is possible to have a SelectionProvider and a SelectionListener in the
same view? I have some problems with my listeners.

Thanks,
kristin

Yes, this is possible.

I have some problems with my listeners.

Did you check the article on the selection service mentioned before?
This should really explain everything. You could also take a look at the
RAP demo, which also uses the selection service, e.g. DemoTableViewPart,
DemoSelectionViewPart, etc.

Hello,

Yes I read the article "Using the Selection Service". But I didn't find a
solution for my problem.
I have 2 views in my application. A table view and a detail view. In the
table view, there is a SelectionProvider and a SelectionListener in the
detail view. If I select a line in the table view, I see the infos of the
selected line in my detail view. So, it works fine for this task.
If I sort my table view with a click on the table column, I want to select
again a line in my table view but I see no infos of this line in my detail
view. That is the selection listener in the detail view see the changing
selection but the ISelection is empty.

It is not simple to explain, but I hope you understand my problem.

Thanks, kristin

I forget a detail. I sort my table column with a listener.
This listener is registered on the table columns of the table in the table
view.
So, I have a listener and a SelectionProvider in my table view.
