Portable Presenter is a package designed to give
presentations.
Presentations are written in options to style-elements grouped into
styles. Well, sometimes you like to
find style-elements in the large number of list kept around.
The following searches are available:
my $o = $object->find('objtype', name); my $o = $object->find(objtype => name); my $o = $object->find('objtype'); my $o = $object->find(objtype => 'SELECTED'); my @o = $object->find(objtype => 'ALL');Where the name is:
SELECTED .
A strange case is with Find on a ShowHandled by show itself:my $style = $show->find(style => 'default'); my $viewport = $show->find(viewport => 'control'); my $slide = $show->find(slide => 'FIRST');All other finds on a show are passed to the selected style. The following two lines are equivalent: $show->find(formatter => 'plain'); $show->find('style')->find(formatter => 'plain'); Finds on a StyleA style is a combination of lists of style-elements. You can search in those lists with find.A few ways you can use this select function: $show->addStyle(...options...) ->find(formatter => 'plain'); my $style = $show->find(style => 'slidenotes') ->find(formatter => 'simple'); $style->find(formatter => 'markup'); $style->find('decoration'); Selections on a ViewportA viewport has a selected style, which determines how a slide for that viewport should be displayed. A find on a viewport will result in a find on the selected style.
$show->find(viewport => 'control') ->find(style => 'slidenotes'); $show->addViewport(...options...) ->find(dynamic => 'default'); $show->find(viewport) ->find(template => 'tm'); |
