First of all in my opinion the scrollbar is not part of the gridlayout
but from the plotWidgets.

My imagination tells me that you do not want a gridlayout but a
QListView or QTableView that have QTextEdits as custom ItemDelegates.
The view than manages it's scrollbar accordung to the number of rows and
the sizeHint()s from the ItemDelegates


When you subclass from QStyledItemDelegate it is rather easy to
calculate the height and return it in the reimplemented sizeHint method.
