Tree Components
The optional row/column footer is available if both row headers and column footers are available. Row headers are made visible using SetShowRowHeader. ShowFooter is used to make column footers visible.
The row/column footer can be shown as a labeled button or just a title. The SetShowRowColFooterButton function defines the row/column footer's display style. The row/column footer or button label may be left or right justified or centered within the row/column footer area boundaries. The SetRowColFooterStyle function defines the position of the text displayed in the row/column footer.
The row/column footer can contain a single or multiple lines of text and a picture (see SetRowColFooterText and SetRowColFooterPicture).
