Re: Why ColumnViewerEditorActivationListener isn't called
I'm going to explain more in depth my problem.In my TableViewer, when the user changes the current row, its contents are
validated, and saved. If they aren't correct, the selection is set back
to the edited row.
I do this thru a selection listener:
viewer.addSelectionChangedListener(selChanged = new
ISelectionChangedListener() {
public void selectionChanged(final SelectionChangedEvent event) {
selectionChanged();
}
});
int lastIndex;
Object lastSel;
protected void selectionChanged() {
if (ignoreSel > 0) {
return;
}
ignoreSel++;
try {
IStructuredSelection sel =
(IStructuredSelection)viewer.getSelection();
Object sel1 = sel.getFirstElement();
if (sel1 == lastSel || saveCurrentRow()) {
lastSel = sel1;
lastIndex = viewer.getTable().getSelectionIndex();
} else {
viewer.cancelEditing();
// If we cannot save current row, then come back
viewer.getTable().setSelection(lastIndex);
}
} finally {
ignoreSel--;
}
}
The problem:
One the user double clicks a cell in another row, that cell is activated,
even though I set the selection back to the old row.
How can I stop the activation going to that cell?
Any help will be grealty appreciated.

Re: Why ColumnViewerEditorActivationListener isn't called
Have you created TableViewerColumn objects and called setEditingSupport onthem?

Re: Why ColumnViewerEditorActivationListener isn't called
Thanks Boris.Yes, I've done so. Otherwise, editing a cell wouldn't work at all.
