API bug - DcmTag::getTagName ()

#1 Post by mlfarrell » Wed, 2009-12-09, 01:33

API bug - DcmTag::getTagName () needs to have a constant qualifier

Otherwise, I'm stuck.

ie:

Code: Select all

      for(int i = 0; ; i++)  
      {
        cout << i << endl;
        DcmElement *el = dfile->getDataset()->getElement(i);
        if(el->getOFStringArray(vstr).bad())
          break;
        dstr = el->getTag().getTagName();
        
        cout << vstr << endl;
        
        gtk_list_store_append(store, &iter);
        gtk_list_store_set(store, &iter,
                            COL_DESCR, dstr.c_str(),
                            COL_VALUE, vstr.c_str(),
                            -1);        
      }
kicks out with
../../src/data_window.cpp:66:0 ../../src/data_window.cpp:66: error: passing 'const DcmTag' as 'this' argument of 'const char* DcmTag::getTagName()' discards qualifiers

Also, is there a workaround so I don't have to recompile the lib for all three OS's that I'm using?

I don't think that this is a bug. The method is not "const" since a lookup in the data dictionary might be performed (if not already done). Btw, why don't you use the method getTagName() on the DcmElement instance?

Jörg, the method getTagName() of DcmElement is protected.

Sorry, you are right. So, please forget the last sentence of my above posting :-)
