Bulk setChemObj in composer

[robertf224]

I can't figure out how to add multiple molecules. Using setChemObj as described here in sequence doesn't work because each call overrides the previous. Is there some way I can add multiple molecules using the current APIs?

The root object in an composer is actually an instance of Kekule.ChemDocument (when calling composer.setChemObj(molecule), the molecule is actually inserted into this document), so the following code may be used to add multiple molecules to composer:

var molecules = [mol1, mol2, mol3];
var chemDoc = composer.getChemObj();
molecules.forEach(function(mol){
  chemDoc.appendChild(mol);
});
