Hi, I added a map object by the name 'nodes' to RecolorWheelPrivate:

std::mapstd::string,RecolorWheelNode nodes;

I then added this snippet for painting recolor nodes from the map:

for (std::mapstd::string,RecolorWheelNode::iterator iter = priv->nodes.begin(); iter != priv->nodes.end(); ++iter) {

dist = (*iter).second._color[1] * outer ;

xx = center_x + cos ((*iter).second._color[0] * 2.0 * G_PI) * dist; yy = center_y - sin ((*iter).second._color[0] * 2.0 * G_PI) * dist;

(*iter).second.x = (gfloat)xx; (*iter).second.y = (gfloat)yy;

r = (*iter).second._color[0]; g = (*iter).second._color[1]; b = (*iter).second._color[2]; hsv_to_rgb (&r, &g, &b); }

I added this snippet to performUpdate() in the recolor-artwork-widget.cpp :

void RecolorArtworkWidget::performUpdate() { if ( update || !desktop ) { return; }

if ( dragId ) { // local change; do nothing, but reset the flag g_source_remove(dragId); dragId = 0; return; }

update = true;

Inkscape::Selection *selection = sp_desktop_selection(desktop); GSList const *items = NULL; //int selObj = 0;

if ( selection ) { items = selection->itemList(); //selObj = g_slist_length (const_cast<GSList*>(items));

RecolorWheel* wheel = (RecolorWheel*) (((RecolorWheelSelector*)(rsel))->getWheel()) ; RecolorWheelNode temp;

for (GSList const *i = items; i != NULL; i = i->next) { SPObject *obj=reinterpret_cast<SPObject *>(i->data); Inkscape::XML::Node* obj_repr = obj->getRepr(); SPCSSAttr* obj_css = sp_repr_css_attr( obj_repr , "style" );

guint32 rgb32 = sp_svg_read_color( sp_repr_css_property( obj_css, "fill", "#ababab") , 0xF0F8FF ); SPColor color = SPColor (rgb32);

float rgb[3] , hsv[3]; sp_color_get_rgb_floatv (&color, rgb); sp_color_rgb_to_hsv_floatv (hsv , temp._color[0] , temp._color[1] , temp._color[2] );

add_node_to_recolor_wheel (wheel, obj->getId() , temp );

}

} update = false; }

There seems to be some runtime error. Opening the RecolorArtwork Dialogbox crashes inkscape. Running gdb shows the warning that "HEAP: Free heap block a90b8f6 modified at a90b8f6 after it was freed" .

Can't figure out whats making the application to crash.

I have uploaded this branch too. It is the latest revision.
