[JavaFX] TreeTableView no renderer for non-leaf nodes

TPD-OpitzFeb 15 2016 — edited Feb 15 2016

Hello,

I'd like to implement a TreeTableWiew with special Renderers (CheckBoxTreeTableCell in the SSCCE)

But in rows the of non leaf nodes I don't want the specialized renderers to be shown.

Can someone please change my example so that the CheckBox is not shown in the first row?
