odgiconveyorcontext::currentdrawable always returns 0
odgiconveyorcontext::currentdrawable always returns 0
hi,
in odgsbasevectorizeview::dodraw - overrided method and all methods called from it, odgiconveyorcontext::currentdrawable always returns 0, though pdrawable prarametrer of dodraw is not 0.
regard,
michal sliwka

currentdrawable is set to odgibasevectorizer (odgibasevectorizer is implementor of odgiconveyorcontext interface) in odgibasevectorizer::dodraw().
if you insert this code to your overriden dodraw() method, your problem will most probably be solved. m_pdrawabledesc is protected member of odgibasevectorizer.
code:
odgilocaldrawabledesc desc(m_pdrawabledesc);
desc.ndrawableflags = ndrawableflags;
desc.persistid = pdrawable->id();
if(!desc.persistid)
desc.ptransientdrawable = pdrawable;
sincerely yours,

unfortunately, it does not work. currentdrawable() always returns 0.

could you please set breakpoint in the end of this code and post results:
- which value has desc.persistid ?
- which value has desc.ptransientdrawable ?

desc.persistid == 0x03089a58
desc.ptransientdrawable == 0
after subsequent call of this code during drawing, desc.persistid changes and desc.ptransientdrawable is always 0.

it's mistaken change in dd 1.13.
we'll fix it in the next release/update.
you can open drawable by its id (desc.persistid) via call odgicontext:pendrawable().
