[java-gnome-hackers] Trees

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

While waiting for my uni project to compile each time this evening, I've
been going through the tree API to see what needs doing. I've updated
the TODO (all based on gtk 2.3.1 - latest I have). There's a lot more to
do than I expected and a few things you might want to comment on:

- I'm not bothering supporting custom treemodels or cellrenderers.
  They're too advanced for the current state of java-gnome

There are many things which could cause performance problems.
These are setting interfaces so that a method will be called for a
number of items in the treeview.
e.g. selectionfunc - determine if a row may be selected
GtkTreeViewColumnDropFunc
gtk_tree_view_column_set_cell_data_func
TreeModelFilter functions
The last two are the biggies - I'm not sure if these will ever be
feasible in java. I think I should add the API with a comment saying
this is not public API - just for testing, then we can remove it later
if needed.

gtk_tree_view_map_expanded_rows - is this useful in any way?

treeview drag methods - I'm not sure what they do. Have to go through
them all again.

treeview signals - are these needed?

TreeModel sort - I won't bother with this. Everyone will use one of the
existing stores with java-gnome.

CellLayout - what is this? I don't think we need it... 

Does anyone know what GtkSelectionData is? it's a parameter in
GtkTreeDragDestIface but I can't find docs for it.
