[Libreoffice] [EasyHack][#34697][MHST] How to get the current page number in Calc, Impress, Draw

[Markus Mohrhard]

Hi,

ScPrintFunc is the correct place but not nPageNo. So
http://opengrok.libreoffice.org/xref/core/sc/source/ui/view/printfun.cxx#2670is
responsible for printing and you should have a closer look at it. I
think
that with the context of lines 2719 to 2778 the main idea should be clear:
-Get the range we need to print to one page
-call ScPrintFunc::Print with this range

Maybe the best idea is to set a breakpoint in ScPrintFunc::Print and look
where it is called and what are the parameters.

I'll translate the german comments in this section for you. If you still
have any questions feel free to write a mail or ask on #libreoffice-dev.

Regards,
Markus
