We selected a style: let us assume it is the default style (you do not have to do anything to get that one). Within a style, you can select a style-element implementation. The default selected style-elements of the default style are:

• Solid backgrounds as decoration,
• Tk fonts as fontset,
• the Default screen templates (with as default template 'tm'),
• a Markup text formatter, and
• the Default dynamic specifications.

When you create a slide, you specify a number of options, which overrule the defaults as are set by the style-elements. There is a huge amount of options (all options). If you try to use an option which is not part of any selected style-element you will be warned.

Adding a slide:

   #!/usr/local/bin/perl -w
   use strict;

   my $show = PPresenter->new;

   $show->addSlide
       ( -title    => 'first slide'
       , -main     => '<HUGE>Hi there</HUGE>'
       );

   $show->run;

• The default for a solid decoration is yellow characters on a solid blue background (if the screen's device is a lcd-projector).
• The default fontset is Tk-fonts: not too nice, but they will always work.
• The default template is 'tm' which divides the screen (for this slide) in a title and a main-part; yes, tm is the abbreviation of 'title main'. The options -title and -main tell PPresenter what to show in those regions.
• The text specified with the two options is interpreted by the selected formatter, the Markup formatter. The title does not contain any markup tags, but PPresenter puts <TITLE> around it automatically. The main part is put in a (much) larger than normal font.
• We do not use any dynamics in this example.

You also have to understand the markup formatter.
