Let's say we want to start at slide 54 right from the command line. Well all there is is $ loimpress -show #which starts at slide 1. Therefore please add $ loimpress -show 54 file.ppt capability etc. Operating System: Debian Version: 4.1.1.2 rc
would be a good idea to implement
Would be really useful in QA.
It certainly will not be straightforward to do this. The command line can fairly easily be parsed to get the result in desktop/source/app/cmdlineargs.cxx Then in desktop/source/app/dispatchwatcher.cxx it will need to be turned into something like a SID_PAGE_NUMBER. (Unfortunately, the current implementation of SlideshowImpl::createSlideList is expecting an exact match on the slide name, like "Slide 3", and not just a number.) At DrawDocShell::Load, the SID_DOC_STARTPRESENTATION causes mpDoc->SetStartWithPresentation( true ), so likely SdDrawDocument will need to be extended to also SetStartingPage(). This is the turning point, when we get to ViewShellBase::Notify which only has a SfxEventHintId::OpenDoc hint that only can check if IsStartWithPresentation and thus calls an option-less SID_PRESENTATION ShowSlideShow sees the SID_PRESENTATION and does a xPresentation->startWithArguments with a hard-coded FirstPage = 0 (which doesn't actually work like you would think, but only works because "0" is never found and thus it falls back to the first slide). So then, SID_PRESENTATION must be extended to accept a starting page, because otherwise every time ShowSlideShow is called it would start at the command-line-provided start page (if we made a GetDocument().GetStartingPage()).
