<!-- Proof of concept of running loleaflet.html in an iframe. Also
shows how to, from outside the iframe, invoke Python scripting in
the underlying LibreOffice instance that manipulates the document
being edited.
This demonstrates using the Python InsertText.py and Capitalise.py
scripts from javascript across iframes.
To test this, do 'make run', and then in your browser open the
equivalent of
2019-06-16 12:28:58 -05:00
http://snorken.local:9980/loleaflet/3304e9093/framed.doc.html if the
2018-07-26 23:16:50 -05:00
browser is running on a different machine, or
2019-06-16 12:28:58 -05:00
http://localhost:9980/loleaflet/3304e9093/framed.doc.html if running
2018-07-26 23:16:50 -05:00
