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

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
