Hi Thomas,
Thanks for your critique...
I see my concept is still quite confusing...I will try to explain
Triggering the slideshow would reveal a special view mode consisting of either of a tiddlylifemap or another fullscreen background and a set of buttons to trigger slides in a special wrapper. These buttons could either be decent in the corner of the screen or on special panel if you have the luxury of a moderator screen. The buttons to display slices would indeed be produced in the moment a tiddler gets into the focus. A list filter could be used to decide wheter the tiddler contains slices or not a thus display different buttons. To build the buttons to trigger the slices it would be necessary to wrap the slice in some code...this is why I would have loved to use the extract widget like the list widget because it makes procedures like this so comfortable...but it could be sufficient to add a prefix and a suffix to perform this. We could also think of generating temporary Tiddlers out of the slices which are deleted when navigating to the next tiddler...but I think for the use of tiddlymap to visualize the slideshow this is not as neat. Being able to reorder the slices by numbers would give users more freedom to sort the slices in the tiddlers...I thought this would not be easy and we can well live without that. When the last slice is displayed the next button should navigate to the next tiddler in the list and thus display the buttons for the next slides, if no tiddler is left it would unreveal the slideshow mode.

I hope all this does not sound totally crazy to you.

So good night
Yours Jan

Hi Jan

    I have two things in mind which in
    combination will make it a little compicated.

I think you are absolutely right here ;–)

    -  The possibility to create slideshows on-the-fly by creating a
    list o
    tiddlers... which means there could be a combination of short
    Tiddlers
    without slices and long Tiddlers with slices

Until here, this sounds like the first concept:
– slides = tiddlers

    I think your second concept will be the clue:
    -In slideshow Mode...

How would this mode be activated?

the Tiddler in focus should generate the slides as a list
This indeed sounds like the second concept
– one tiddler contains all the slides in the form of a list
– is this a special kind of tiddler?
– I guess it would /contain/ the list permanently (as opposed to generate /in the moment it gets the focus/)?

    (if no slice is marked the tiddler Text should be used as one slide)

– this is the opposite of what extract does: the macro collects marked slices. No marks => no output.
But of course you could mark the whole text as one slice.

     --It would be great if the slides were ordered by the numbers of
    the slicemacro but that is a secondary question.

Standard of order of extraction would be
– order of tiddlers in the list (story river in your case)
–– order of slices within tiddlers

    -After the last slide is displayed of the current Tiddler is
    displayed,
    the next-button should navigate to the next tiddler in the list.

– and what would happen there?

    I hope this does not sound too complex.

Bluntly: Yes it does. But maybe it is just me … or the fact that I am not familiar with tiddlymap? I am afraid you want to put a slideshow (all slices from one tiddler) into a slideshow (all tiddlers in the story river)? Wouldn’t it be easier to collect all slices from all tiddlers in one list (concept two) istead of mixing the two concepts?

Excuse me if I am not able to see the advantage of your strategy (yet) or if I missunderstood someting!

    If you get the extract macro to
    work like the list-widget

I would recommend to use the extract macro inside the existing list widget as the footnote demo <http://tid.li/tw5/numbers.html#Footnotes:About%20%5B%5BChapter%203%5D%5D%20%5B%5BChapter%201%5D%5D%20%5B%5BChapter%202%5D%5D%20Footnotes> does.

Have a nice evening,
Thomas
