[Libreoffice] How to catch the following events: OnAlphaCharInput, OnInsertStart, OnInsertDone, OnNonAlphaCharInput

[John Gillanders]

Hello all,

I found out that the OnAlphaCharInput and OnNonAlphaCharInput events are only relevant to Frame objects, so do not do what I was hoping for, and OnInsertStart and OnInsertDone are related to AutoText objects, so these also do not do what I was hoping for.

What I am actually trying to achieve is a way to hook into events in OpenOffice so that I am able to catch all edits that a user does to a Writer document and do something with the related information (I need to receive the full information of what changed). I know there is a new undo/redo API in the 3.4 version of OpenOffice, but Frank Schönheit advised that this API will only provide the localised name of the action that has just happened, whereas I really need access to the full details of the action. Frank suggested that there might be events for all different kinds of edits that I can catch, which is what led me to where I am now.

Do anyone know of anything that may help me with this (catching all edits to a document and inspecting details of each edit)?

Regards,
John Gillanders
