[Libreoffice] [EasyHack][Print current page] How to get the last active page number?

[Peter Jentsch]

Hi Skyler,

if you want to access the page number at the currently selected position
in the document, you'll have to first get the current selection
(http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/OfficeDev/Component/Controllers#XSelectionSupplier),
figure
if there's actually a *point* in the document selected (otherwise the
selection might span multiple pages), the create a
com.sun.star.text.TextLayoutCursor, which provides an XPageCursor
interface, which in turns provides a method to tell which page you're
currently on.

It might well be possible that the current page number is also exposed
as a property of an TextRange service that might be returned by
XSelectionSupplier.getSelection (if a textrange and not something else,
a frame object for example, is currently selected).

Getting this right for every possible type of selection aint trivial, by
the way.

Good luck,

Peter

The interesting thing's IMHO the
