Handling UNO objects, images, lists (in Python)

[_savage]

These questions are somewhat Python related, but I'd think they can be answered for different languages as well.

• Is there a way, given an UNO object like a paragraph or text portion (each of which implements different interfaces), to read certain attributes from it using a generic method? For example, I can say par.CharHeight but is there something like read_attr(par, "CharHeight") or some such?
• When iterating over the paragraphs and text portions of a document, how do I recognize numbered/unordered lists?
• Same as above, how to I recognize images?

I feel like these questions I could answer myself by reading the API but I found it difficult to browse it (very complex). There's a Wiki which has an occasional answer but in general I find it difficult to dig through UNO. Where is a good and comprehensive document, if there is one?

Of course, you should be fluent in Python.

The document seems a little outdated, but it's an interesting introduction. Thanks!

It didn't really answer my questions though: how to I recognize images and numbered lists when I iterate over the paragraphs of a document? I also tried different ways of reading attributes (as described in the above document) but that's didn't really work either.

So I'm not any farther than before

Well, it seems like lists (enumerations) are implemented by paragraph style "NumberingStyleName" different than an empty string, for example

Code: Select all

> par.NumberingStyleName
'WW8Num2'

indicates an element of a numbered list. Other properties like "ParaIsNumberingRestart" and "NumberingStartValue" and "NumberingLevel" give more information on the context of this paragraph list. So it seems, at least.

As for images, I am still unsure.

As for how to query random properties of a UNO object, I am still unsure.

I also assume that footnotes are handled as paragraph styles also?

This is how it seems to work, although some more checks to make sure a particular interface is implemented by a UNO object would help:

Code: Select all

>>> type(par)
<class 'pyuno'>
>>> getattr(par, "ParaStyleName")
'Free Form'
>>> getattr(par, "CharFontName")
'Comic Sans MS'
