How to obtain the TableViewer from a Table

Question

I created a TableViewer in JFace.
Later on I iterate through the UI-Tree and have only access to the SWT-API-Level objects.
In the case of the TableViewer it is the Table.
From the table, I need then a link to the TableViewer.

Does any one know how to do this?

Answer 1

Not possible. Keeping a reference to created viewer is the only way.

Answer 2

@Martti is right. Not possible directly via the viewer API.

For cases, where I need to get to the viewer from the control, I usually add viewer.getControl().setData(Viewer.class.getName(), viewer); - I can then later retrieve the viewer again with viewer.getControl().getData(Viewer.class.getName();

I prefer this method to keeping a separate Map<Control, Viewer>, as this is automatically cleaned up :-)
