vertical alignment in simpleslides

vertical alignment in simpleslides

[Curiouslearn]

Hi

Today I started making lecture slides for one of my classes and
decided to try out simpleslides. First of all, thanks to Thomas and
Aditya for writing the module.

I had a question regarding vertical alignment. Consider the following
minimal example:

               \usemodule[simpleslides][style=Swoosh]
               \starttext
               \SlideTitle{Context can be used for \dots}

              \startitemize[n]
               \item
                   Writing your articles
               \item
                   Making slides for presentations
              \stopitemize

              \stoptext

The two items appear at the top of the slide. Is there a command or a
setting such that items will be aligned around the center of the
screen?

Thank you for your help.

Bharat

\setupitemize[before=\vfill,after=\vfill]

You can also add

\setupitemize[1][inbetween=\vfill]

Another option is:

\def\StartSlide#1%
   {\SlideTitle{#1}
    \vfill}

\def\StopSlide
   {\vfill}

and then

\StartSlide{...}
...
\StopSlide

Thanks for the response, Aditya.

However, the first method

    \setupitemize[before=\vfill,after=\vfill]

does not change anything for me. The items are still at the top.

The second one (\setupitemize[1][inbetween=\vfill]) changes things.
However, the first item is at the top of the screen and the second is
at the bottom. I would like them to be near the center. Something like
what 'middle' does for horizontal alignment with two words, I want to
do for vertical alignment.

Thanks.

Didn't realize that you were using the Swoosh style, that sets its title 
using a layer. Therefore you need to use

\setupitemize[before=\null\vfill, after=\vfill]

This is useful only if the previous command works. You can play around 
with the amount of fill at the start and end to create symmetric looking 
layouts. For example:

\setupitemize[1][before={\null\vskip 1ex plus 2fill},
                  after={\vskip 1ex plus 3fill}]
\setupitemize[1][inbetween=\vfill]

(Actually, rather than using the low-level \vskip, it is better to use 
ConTeXt high level interface using \blank. But I do not remember how 
create \blank with vertical glue).

Awesome!! This worked great. I need to understand what 2fill and 3fill
does. I will try looking at Victor Eijkhout's book. But if you know of
any other easy reference, please let me know.

Thanks for your help.

Think of fill as a "spring" that pushes both sides. 2fill is a spring that 
pushes twice as hard. With a \vskip 1ex plus 2fill at top and \vskip 1ex 
plus 3fill at bottom, 2/5 th of the total blank space is on the top, and 
3/5 th is at the bottom.

With inbetween=\vfill, and two items, the equation changes to

2/6th of the empty space on top
1/6th of the empty space inbetween the two items
3/6th of the empty at the bottom
