I don't know about "Flex", seems to be a new name. In LyX 1.6 the
definition in a layout file can be done by e.g.::
InsetLayout LandscapeSlide
LyXType custom
LatexType Environment
LatexName slide
Decoration classic
LabelFont
Size Small
EndFont
MultiPar true
LabelString "Landscape Slide"
End
instead of (or in addition to)::
Style LandscapeSlide
CopyStyle --Separator--
LatexType Environment
LatexName slide
NextNoIndent 1
Margin Static
LeftMargin N
ParIndent ""
TopSep 0.4
LabelType Top_Environment
LabelString "Landscape Slide:"
End
(There are 134 "InsetLayout" definitions in <LYXDIR>/layouts/ in LyX 2 (svn)
130 of them have "Flex:" in the name.)
