Detailed Description

Static copy of the Lua Debugger script editor for the Theme Designer.

Shows the udprtt.lua example of the Lua debugger chapter of the Developer's Guide, highlighted by the debugger's own LuaSyntaxHighlighter, with a breakpoint, the line the debugger is paused on and a selection, so every color of the theme's code section is on screen. Colors come only from setPreviewColors(), so a draft can be shown without touching the application. Built only with Lua, like the debugger.

With picking enabled (picker()) a click names the theme color that paints the spot, found with ThemePreviewPick's key render of a hidden copy of this widget.
