RE: [Java-gnome-developer] problem with GtkTree

[Jeffrey M. <Jef...@Br...>]

You are correct in that there are no methods to set
the plus or minus pixmaps.  There are members of
the GtkTreeItem structure that represent these
widgets and that a C programmer would set directly.
The methods I added to the bindings are there to allow
a Java developer to access the structure elements.

Drag and Drop is not supported at this time.
