Hi,
I have a tableviewer in my program. I selected one row in the
tableviewer, then I tried to add this row into the next position like this:
IStructuredSelection selection =
(IStructuredSelection)viewer.getSelection();
if (selection.isEmpty()) return;
for(Object o:selection.toList()){
viewer.insert(o, viewer.getTable().getSelectionIndex() + 1);
}
As result I got it, but the next row is missing. However, I got a prolem
when I sort this tableviewer. Exactly for that, the rows in the
tableviewer can be sorted in order, but the tableviewer displays just
the old information instead of the updated information.
Many thanks.
Greetings
Wen

Hi,
thanks for your infos. But I still face to the problem, how can I add
something new in my table model or delete a row from it. I know two
methods in the ContentProvider are very important for that: getElements
and inputChanged. I'm still testing this and I can't find some examples
exactly for this thema from the google. Can anyone help?

Hi,
If Viewer#insert() / Viewer#remove() doesn't work you can do it brute
force by removing/adding the Model-Element from/to your content-model
and calling Viewer#refresh().
The best you can do to get help is to provide a standalone snippet which
we can run to see the problem. To make sure your code can work at all
I'd first test against Standard-JFace libs who are using SWT because if
it doesn't work there it won't either in RAP (I assume that JFace/SWT is
much more tested than RAP's widget libs :-).

Hi,
the problem was resolved. I have defined the table data inside the
method getElements() in the ContentProvider before. Then I change this
and put the data with viewer.setInput(getInputData()). If I delete or
add rows into the table view, just generate a new input data(or change
this data), and use the method setInput(newInputData) again. It works fine.
Thanks for all the helps :-)
