Is there a standard TableViewSorter? [message #461410]

I want to allow the user to sort a table by clicking on the column header.
Is there a standard way in JFace/RCP to implement this? Or do I have to
roll my own ViewerSorter which responds to mouse clicks?

Thanks

Mark

Hi,

No there isn't but I once dicussed this privately with JFace leads.
Please file a bug report agains Platform>UI and prefix your Summary with
the word [Viewers]. Still I don't think if anybody else volunteers to
implement it it won't go in 3.3 because API freeze is in about 4 weeks.

There is a ViewerSorter class that you need to extend and implement a
compare and doSort methods. Then you just tableviewer.setSorter(your
sorter).

Hi,

Well I guess he knows that but what he requests is that JFace wraps this
for him.

Something like (the code below uses the new Viewer-API):

------------------8<------------------
TableViewerColumn vcolumn = new TableViewerColumn(tableViewer,SWT.NONE);
vColumn.setComparator(new CustomViewerComparator());
// this automatically sets up all listeners in the background
// no other custom code needed
....
------------------8<------------------
