Re: [Java-gnome-developer] Question: TreeView & TreeStore and Listeners

[Mark H. <mh...@ca...>]

Have you looked at selection for each function? It will execute a method
for each selected row of a tree.

Iterating over all rows is likely to be quite slow since it uses many
jni calls. The selection for each method does not.

Gtk 2.3 and hence java-gnome 2.5 will have a much nicer api for doing
this - there is a TreeIter[] getSelectedRows() method.
