A Tree consists of TreeRows and cell renderers. The TreeRow places the open/close icon and the icon for the row and then its cellRenderer. If a Checkbox is the cell renderer then you'll get see the open/close then the folder/leaf icon then the checkbox then the checkbox label.
Have you considered just replacing the folder/leaf icon with a checkbox icon and writing code to handle it being clicked? When a checkbox is clicked you are responsible for setting properties on all the child nodes so they know whether to display the checked or unchecked version. Use an iconFunction to calculate which icon to use. --- In [email protected], "Tom Jeffery" <[EMAIL PROTECTED]> wrote: > I just started looking at doing something similar.
