Editable GridTableViewer cell on the spot [message #759327]

Hey

I'm using a GridTableViewer (org.eclipse.nebula.jface.gridviewer.GridTableViewer) to display rows of data (Strings, single column per row). I want to add one row/cell programmaticaly, and it must become editable on the spot, with the cursor set in edit mode (blinking, ready to type) so I can input data and then save it. So, it's
about adding a new row and filling it on the spot, so I want the last row to editable and the cursor set on it when I click the "add new row button).

Can anyone please help me, how can this be done ? I need an answer fast Smile

Thx,
Flavian

Ty,

I'm getting a cast error from "java.util.ArrayList cannot be cast to MyClass".

This is my code. Can you please give me more details on how this should be implemented. Or is this cast exteption a bug ?

// declaration
private GridTableViewer headerTableViewer;

// for the first element
headerTableViewer.editElement(headerTableViewer.getElementAt(0), 0);

So where is the exception happening?

Can we please see a stacktrace? Please also note that the method you are
using is meant to be internal to the framework as stated by the javadoc.
