Inkscape::GC::Anchored

List of all members.


Detailed Description

Note:
NB! Unless explicitly stated all methods are noref/nostrcpy
Todo:
Though Inkscape::XML::Node provides "signals" for notification when individual nodes change, there is no mechanism to receive notification for overall document changes. However, with the addition of the transactions code, it would not be very hard to implement if you wanted it.
Note:
Inkscape::XML::Node itself doesn't use GObject signals at present -- Inkscape::XML::Nodes maintain lists of Inkscape::XML::NodeEventVectors (added via sp_repr_add_listener), which are used to specify callbacks when something changes.
Here are the current callbacks in an event vector (they may be NULL):

void (* child_added)(Inkscape::XML::Node *repr, Inkscape::XML::Node *child, Inkscape::XML::Node *ref, void *data); Called once a child has been added.

void (* child_removed)(Inkscape::XML::Node *repr, Inkscape::XML::Node *child, Inkscape::XML::Node *ref, void *data); Called after a child is removed; ref is the child that used to precede the removed child.

void (* attr_changed)(Inkscape::XML::Node *repr, gchar const *key, gchar const *oldval, gchar const *newval, void *data); Called after an attribute has been changed.

void (* content_changed)(Inkscape::XML::Node *repr, gchar const *oldcontent, gchar const *newcontent, void *data); Called after an element's content has been changed.

void (* order_changed)(Inkscape::XML::Node *repr, Inkscape::XML::Node *child, Inkscape::XML::Node *oldref, Inkscape::XML::Node *newref, void *data); Called once the child has been moved to its new position in the child order.

Inkscape::XML::Node mini-FAQ

Since I'm not very familiar with this section of code but I need to use it heavily for the RDF work, I'm going to answer various questions I run into with my best-guess answers so others can follow along too.

 SP_ACTIVE_DOCUMENT->rroot       

(but it's better to arrange for your caller to pass in the relevent document rather than assuming it's necessarily the active one and using SP_ACTIVE_DOCUMENT)
