+-- presentation goodies for Ipe
+
+--[[
+
+SUMMARY
+
+ This ipelet adds a few goodies for presentation, including
+ 1. Ability to create beamer-like boxes with/without header
+ 2. Add a framed box for the selected objects (including text)
+ 3. A function to deselect all selected on all pages
+ 4. The boxes can be edited as text/path objects (press E)
+ 5. A few items can be added to the style sheet to add preferred
+ symbolics for box colors etc. This has the benefit that this
+ preferences can be changed to affect all boxes (see below).
+
+ The design of these boxes is from Martin Nöllenburg's presentation
+ example posted on the Ipe7 wiki page.
+
+STYLESHEET (CHANGING PREFERRED SETTINGS)
+
+ Example style sheet to cascade with presentation.isy is as follows.
+
+---- content of example.isy ---
+example removed, not possible to upload this file to the ipe-wiki otherwise
+---- end content of example.isy ---
+
+ where:
+ tab_header= color of the tab header in a tabbed box
+ tab_body = color of the tab body in a tabbed box
+ box_fill = fill color a box
+ box_border= color of the box border
+ boxborder = linewidth of the box border
+
+ The preferred box mode (stroked/filled/strokedfilled) can be changed by
+ changing the hard-wired value (no stylesheet option) PREFERRED_BOX_MODE below
+
+ With the above style sheet, one can start an empty presentation using
+ ipe -sheet presentation -sheet /path/to/example.isy
+
+SHORTCUT
+
+ Shortcuts to these functions can be changed as for other ipelets:
+ shortcuts.ipelet_x_presentation = "Key"
+ where x is the index (starting 1) of the sub-menu for the function
