C++ (Cpp) VMDApp::molecule_numframes Examples

Example #1

File: MainFltkMenu.C Project: VictorMion/vmd-cvs-github

static void curframe_cb(Fl_Widget *w, void *v) {
  Fl_Input *inp = (Fl_Input *)w;
  VMDApp *app = (VMDApp *)v;
  int val = atoi(inp->value());
  int max = app->molecule_numframes(app->molecule_top());
  if (val < 0) val = 0;
  if (val >= max) val = max-1;
  app->animation_set_frame(val);
}

Example #2

      break;
    }
  if (molid < 0) return;
  
  // this code snippet is replicated in MolBrowser.C:
