ClipboardManagerImpl::getFirstObjectID restricted to very few object types
Dear Inkscape Team,
I try to make my bool LPE work with any objects, not just paths. I got around most issues (like getting a PathVector from an SPItem), but I am lost with ClipboardManagerImpl::getFirstObjectID which is used by OriginalItemParam. It is restricted to very few object types (g,path,use,text,image,rect). Since the clipboard is used to set the operand path of the LPE, it is restricted to these types.
Is there a good reason for this restriction or is this a bug / non feature? What would be an appropriate SVG tag list?
This function seems to be used only in very few places, so I guess it wouldn't do a lot of harm to fix it? Would there be a better implementation than checking for a list of literal SVG types?
Btw.: Is the LPE parameter type OriginalItemParam / ItemParam operational or is this beta code I shouldn't use?
Best regards,
Michael
Dear Inkscape Team,
I solved the issue with getFirstObjectID by replacing it with getShapeOrTextObjectId in ItemParam::on_link_button_click(). This works as expected. I think ClipboardManagerImpl::getFirstObjectID should be removed. It is only used in one other place (ObjectSet::relink()) and likely doesn't do much good there either.
Best regards,
Michael

SPCurve *c = NULL; c = shape_origin->getCurve(); if (c) { Geom::PathVector c_pv = c->get_pathvector(); }
Also you can get the "d" attribute from repr and parse it

Not sure if I undertand but getFirstObjectID need to get from any type item you have on clipboard not a reduced list

I think is better retain first function and add a item switch for text

Is not constrained by the type of element.

What would be the advantage of using ClipboardManagerImpl::getFirstObjectID?
Best regards,
