[platform-swt-dev] setting focus to cell-editor

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

I know that this is the SWT-Maillinglist but I tried more than once at 
the newsgroups but nobody is willing to answer this question there :-).

I've just started to implement a key-listener who has the following purpose:
When the TAB-key is pressed I want to go to the next column in the 
TableViewer and start editing it. I'm already catching the TAB event but
I somehow couldn't open the editor in the next column what am I doing 
wrong here. It must have missed something very basically or the whole 
approach I'm taking is completely wrong?

Although in my understanding when using SWT/JFace as an input-gui e.g. 
to a database this feature is mandatory its not part of it until now.

        this.columnIdx = columnIdx;
        this.viewer = viewer;
    }

                if( viewer != null ) {
                    CellEditor[] editors = viewer.getCellEditors();
                    e.doit = false;

                        // editors[columnIdx+1].getControl().forceFocus();
                    } else {
                        System.out.println("We reached start or end of 
row");
                    }
                } else {
                    System.out.println("I have no viewer");
                }
            } else {
                System.out.println("No need to cancle its not a 
tab-event");
            }
    }
}

Why isn't there a mailling list for JFace like there is this list for 
swt implementation details?
