Leave the window blank for the default size, otherwise enter a tuple of (width, height) pixels. Use the Grid Position (row, column, row span, column span) to position the graphical element in the window. Use the Notebook Param (notebook-id, page-index) to place the graphical element inside of a notebook page.
