Tableeditor [message #121299]

Hi all

i just downloaded RAP 1.2 M5 and the problems i have with TableEditor in an
TableViewer Cell persist.

When scrolling TableViewer the TableEditor does not scroll (vertically),
When resizing columns the TableEditor does not scroll (horizontally),

I finally found a workaround i will describe here just in case other people
have the same problem:

The solution bases on the observation that a manual layout() on the
tableeditor does move the tableeditor to the correct cell.
Said that, i did the following:
1. added a MouseListener to the TableViewer
2. added a ControlListener for every TableViewer Column
3. added a SelectionListener for every TableViewer Column

now i just called layout() for every TableEditor in use (see example code
below)
public void tableEditorRefreshBug()
{
for (int i=0; i<artikelList.size(); i++)
{
Artikel bugArtikel = (Artikel) artikelList.get(i);
for (int ii=0; ii<bugArtikel.tableEditor.length; ii++)
{
if (bugArtikel.tableEditor[ii]!=null)
bugArtikel.tableEditor[ii].layout();
}
}
}

I used the MouseUp, controlResized und widgetSelected to call the code
above.

Question to the RAP-Team:
Is org.eclipse.swt.custom.TableEditor not (yet) supported?
Maybe only org.eclipse.jface.viewers.CellEditor is supported?

Thanks
Andrej

Hi all

it looks as i'am not going to get an answer/reply to the problem
described, my first posting was on Feb, 8th. As i can see all other
postings are being answered.

Am i doing something wrong, maybe my description is not clear enough?

do i have to open a bug and write a snippet to clarify?

Thanks
Andrej

Hi Andrej,

sorry for the late response. Your assumption is right. The
TableEditor code was only activated to support JFace CellEditors and
isn't intended to be used outside CellEditors.

Hi Rüdiger

thank you very much for your reply.

do you intend to support TableEditor in a future release of RAP or will
"only" CellEditor be supported?

I do ask because i have to decide wether to leave my code as it is and
wait for a future release of RAP that supports TableEditor (this would be
ok for the moment as i managed to relayout TableEditor manually).

But if you say TableEditor will never be supported i'd better throw away
the TableEditor-Code and subclass Celleditor to write my own Editor (in
fact i need only a Button in a Cell so that should not be terribly
difficult).

Thanks
Andrej

No, we do not intend to support TableEditor "outside" CellEditors.
