Hello,

I am currently playing on win32 and linux with lablgtk2 (snapshot 20040319 from CVS) and I encountered few problems.

1/ Rsvg
It is not possible to load rsvg files on win32 platform with the render_from_file function. Changing opening files with open_in_bin instead of open_in should fix it in rsvg.ml

2/ GTree
When I was trying to know in which column of the tree view was the cursor, I could not use the method get_cursor of the view class. I think there is an error in the type declaration of this method. If you check the gtk doc a GtkTreeViewColumn should be returned by the function gtk_tree_view_get_cursor (). So the type of the method should be changed like this (tree_path option * tree_view_column obj option) instead of (tree_path option * tree_view_column option). The "obj " is important if you look at the type tree_view_column in gtk.ml (note that the module TreeView in gtkTree.ml should be changed accordingly).

Then the last point, I cannot succeed having the method set_visible_func (model_filter class) to work. I have always a segfault. There is a simple test to do changing the tree_model.ml example as follows :
replace (in let make_model data) :
f#set_visible_column vis_col 
by :
f#set_visible_func (fun m row ->
   let b = m#get ~row ~column:vis_col in
   b)

I do not know what I am doing wrong here, but I am stuck.
Any help would be appreciated.

regards
