Slide Show Plugin
Create web based presentations based on topics with headings.
Introduction
There is already a defacto standard for presentations, why this plugin? This plugin makes sense for organizations that do already have lots of content in TWiki: It is easy to create a web based presentation that contains many links to related content. The plugin does not try to compete with the bells and whistles of the other presentation program, but compelling interactive presentations can be made using the TML (TWiki Markup Language) and plugins, such as
TWiki:Plugins.ChartPlugin,
TWiki:Plugins.GaugePlugin,
TWiki:Plugins.SpreadSheetPlugin,
TWiki:Plugins.TWikiDrawPlugin.
Any topic with headings can be converted into a slideshow. Each slide starts with a
"---++"
heading. There are two modes to view a topic:
- Normal topic view mode: Headings and text is shown in the usual TWiki rendering, representing the outline of the slideshow. This mode is useful to print handouts.
- Presentation mode: Each heading with text is shown as a slide; the format is based on a slide template.
You can start the presentation by clicking on the "Start presentation" button.
Navigation
While in presentation mode you can move around slides using navigation buttons and keys:
Button |
Key |
Action |
|
Home |
Go to first slide |
|
Left-arrow, Page-up |
Go to previous slide |
|
Right-arrow, Page-down |
Go to next slide |
|
End |
Go to last slide |
|
Esc |
End presentation |
Slide navigation is quick because it is done using anchor jumps within the same page. Key-based navigation requires JavaScript enabled.
Syntax Rules
How to Create a Slideshow
- Start with
%SLIDESHOWSTART%
- Use the optional
template
parameter to specify your own slide template topic, e.g. %SLIDESHOWSTART{ template="MyOwnSlideTemplate" }%
- Create the slides. Start each slide with a
"---++"
heading and add text like paragraphs, bullets, tables and images.
- Hint: Make sure to keep each slide short enough so that you do not need to scroll to see all text of a slide during the presentation.
- Note: You can use any heading level you like, but use the same for all slides.
- End your slideshow with
%SLIDESHOWEND%
How to Create Your own Slide Template
To create your own template topic, copy the "Default Slide Template" section below into your own slide template topic and customize it to your needs. It can be activated as the default template in the plugin's
TEMPLATE
setting, or per slideshow with the
%SLIDESHOWSTART{ template="MyOwnSlideTemplate" }%
setting.
- Use an HTML table that defines a slide. For example, create one row for the slide title, another one for the slide text.
- These keywords can be used:
Keyword | What it means |
%SLIDECOMMENT% | The comment of the slide (optional; appended to slide of missing) |
%SLIDENUM% | The current slide number |
%SLIDETITLE% | The heading of the slide |
%SLIDEMAX% | The last slide number |
%SLIDENAVFIRST% | The navigation button for "First slide" |
%SLIDENAVLAST% | The navigation button for "Last slide" |
%SLIDENAVNEXT% | The navigation button for "Next slide" |
%SLIDENAVPREV% | The navigation button for "Previous slide" |
%SLIDENAV% | The navigation buttons for "First", "Previous", "Next" slide |
%SLIDENAVALL% | The navigation buttons for "First", "Previous", "Next", "Last" slide |
%SLIDETEXT% | The text of the slide |
- Only text between
%STARTINCLUDE%
and %STOPINCLUDE%
is used for the template.
