Hello,

After adding a text box, the text box object (MTextBox) is
available from the object list of the MDocument attached to the reaction
molecule:

MDocument
doc = rx.getDocument();

for (int i = 0; i <
doc.getObjectCount(); i++) {

if
(doc.getObject(i) instanceof MTextBox) {

. .
.

}

}

Best Regards,
