You've created the tree/treev correctly.  You've created the nodes
correctly.  Then you must link the treev into the viewTree.  Use
LinkTree to attach it to its parent view:

	treev_LinkTree(self->treeView,	 self /*?*/);

This version of the code should work:

draw_tree(self)
  struct infuse *self;
{	
	struct tree_node *node;

	self->tree = tree_New();
	self->treeView = treev_New();
	treev_SetDataObject(self->treeView, self->tree);
	node = tree_CreateRootNode(self->tree, "Root Node", 0);
	tree_CreateChildNode(self->tree, "Child 1", 1, node);
	tree_CreateChildNode(self->tree, "Child 2", 2, node);
	treev_LinkTree(self->treeView,self ) ;
}
