Hi, if I would be in you I would not continue to create and destroy the widgets on the notebook pages. For simplicity (and processing speed) I would draw in glade all possible widgets and then from the code just show/hide what you need according to the selected row, possibly grouping the widgets that are together to be shown in containers so that you just hide/show the father of all of them. HTH, cheers, Giuseppe.
