Function Documentation

void create_universe_browser (  void   ) 
 

Create the Universe browser window.

The window data structure is the global wnd_univ_browser.

struct o* o_get_gui_ancestor (  struct o *  o  ) 
 

For an obj, returns his father obj.

For a go in a top level group, returns the page. For other gos, returns their father group.

gboolean vrr_kernel_store_iter_parent (  GtkTreeModel *  tree_model,
GtkTreeIter *  iter,
GtkTreeIter *  child
)  [static]
 

Fills the iter data with the pointer to the parent object.

If the parent object is a top level group, sets the pointer to point to parent page instead.

Initial value:

 { G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING,
        G_TYPE_BOOLEAN, G_TYPE_BOOLEAN, G_TYPE_STRING }
