<!-- 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
|
|
http://snorken.local:9980/loleaflet/3304e9093/framed.html if the
|
|
browser is running on a different machine, or
|
|
http://localhost:9980/loleaflet/3304e9093/framed.html if running
|
|
on the same machine.
