This is for use by the FE in * implementing the nav center. * * The RDF structure could be a gnarly graph whose nodes are RDF_Resource. * There can be multiple tree views (HT_View) into this graph. Corresponding * to each view, there is a hyper tree whose nodes are HT_Resource. * Each HT_Resource belongs to exactly one HT_View. * The FE iterate over the hypertree to draw it. It can start the iteration * either at the top or at some interior node. When some state change occurs * in the hypertree, the FE will get notified about the node on which the * change took place. At that point, it can either redraw the whole thing * or do a partial redraw. The FE does this by iterating over the relevant * portions of the hypertree. Since the hypertree is a strict tree, the FE * can also iterate upwards. * * * Possible state changes to the hypertree of an HT_View include : * (i) addition/deletion of nodes * (ii) containers closing/opening * (iii) selection changes * These changes could occur either because of * (i) User clicking around the tree * (ii) Network activity * (iii) scripts running * The FE can recieve notifications about these activities. * If the FE does not want to be notified about something, it can set * the notification mask to block certain notifications. */ NSPR_BEGIN_EXTERN_C /* Opaque data structures */ typedef struct _HT_ViewStruct* HT_View; typedef struct _HT_PaneStruct* HT_Pane; typedef struct _HT_CursorStruct* HT_Cursor; typedef struct _HT_ResourceStruct* HT_Resource; /* for use with HT_GetTemplate */ enum TemplateType { ht_template_chrome, ht_template_management, ht_template_navigation }; /* * This is the Notification structure that gets passed to the HT layer on * creation of the view.
