This is similar to the purpose for which I created the modal window cell
editor concept. If your cell editor factory returns an object that is an
instance of qx.ui.window.Window, it will be automagically made modal and the
function that you've registered with
table.setModalCellEditorPreOpenFunction() will be called with the cell
editor object and cellInfo as parameters. Upon return from that function,
(or immediately if no function has been registered), the window will then be
opened. When the window is closed, typically by th user pressing a Save
button of some sort, the value for the particular cell which was clicked
will be retrieved in the normal fashion, by calling the cell editor
factory's getCellEditorValue() method with the cell editor as its parameter.
You can look at table/pane/Scroller.js, methods startEditing(),
stopEditing(), flushEditor(), and cancelEditing() for additional hints. I
suspect that upon Save, you'll want to add the row to the data model, rather
than expecting the closing of the modal window to save everything, since you
want to add multiple rows.
Alternatively, you could simply have an Add button that adds a new row to
the model, using a modal window in a similar fashion to what the modal cell
editor would do.
