Hi Jabiertxo,
You should use sp_item_list_to_curves (path-chemistry.h). This avoids duplicating code. Your item does not have to be selected to use sp_item_list_to_curves. You should modify path-chemistry.cpp, so that it handles the two arguments GSList **selected = nullptr and GSList **to_select = nullptr correctly.
regards, Johan

Hi to all, first sorry for this big mail.
I want to convert a SP_RECT to path. This rect isnt selected and dont want to select it.
The svg is a document with only a group and inside the SP_RECT. I test it whith two object inside and the same error.
The code i use is:
if ( SP_IS_RECT(subitem) ) { SPDocument *doc = subitem->document; Inkscape::XML::Document* xml_doc = doc->getReprDoc(); Inkscape::XML::Node *repr = xml_doc->createElement("svg:path"); /* Transformation */ repr->setAttribute("transform", subitem->getRepr()->attribute("transform")); /* Style */ gchar *style_str = (gchar *) sp_style_write_string(subitem->style); repr->setAttribute("style", style_str); g_free(style_str); /* Mask */ gchar *mask_str = (gchar *) subitem->getRepr()->attribute("mask"); if ( mask_str ) repr->setAttribute("mask", mask_str); /* Clip path */ gchar *clip_path_str = (gchar *) subitem->getRepr()->attribute("clip-path"); if ( clip_path_str ) repr->setAttribute("clip-path", clip_path_str); /* Rotation center */ repr->setAttribute("inkscape:transform-center-x", subitem->getRepr()->attribute("inkscape:transform-center-x"), false); repr->setAttribute("inkscape:transform-center-y", subitem->getRepr()->attribute("inkscape:transform-center-y"), false); /* Definition */ gchar *def_str = sp_svg_write_path(SP_RECT(subitem)->getCurve()->get_pathvector()); repr->setAttribute("d", def_str); g_free(def_str); Inkscape::XML::Node *parent = subitem->getRepr()->parent(); gint pos = 0; char const *id = subitem->getRepr()->attribute("id"); pos = subitem->getRepr()->position(); // remember id gchar *title = subitem->title(); gchar *desc = subitem->desc(); subitem->deleteObject(false); // add the new repr to the parent parent->appendChild(repr); repr->setPosition(pos > 0 ? pos : 0); repr->setAttribute("id", id); SPObject *subitem = doc->getObjectByRepr(repr); if (title && subitem) { subitem->setTitle(title); g_free(title); } if (desc && subitem) { subitem->setDesc(desc); g_free(desc); } if (repr) { Inkscape::GC::release(repr); repr = NULL; } //item_list = g_slist_append(item_list,subitem); //continue; }
And the backtrace error is:
** Message: need to add dynamic switch ** Message: need to add dynamic switch ** Message: need to add dynamic switch
** (inkscape:3452): CRITICAL **: virtual unsigned int Inkscape::XML::SimpleNode::position() const: assertion `_parent != NULL' failed
