47 // With this inset it will be possible to support the latex package
48 // float.sty, and I am sure that with this and some additional support
49 // classes we can support similar functionality in other formats
51 // By using float.sty we will have the same handling for all floats, both
52 // for those already in existance (table and figure) and all user created
53 // ones¹. So suddenly we give the users the possibility of creating new
54 // kinds of floats on the fly. (and with a uniform look)
57 // \newfloat{type}{placement}{ext}[within]
58 // type - The "type" of the new class of floats, like program or
59 // algorithm. After the appropriate \newfloat, commands
60 // such as \begin{program} or \end{algorithm*} will be
62 // placement - The default placement for the given class of floats.
63 // They are like in standard LaTeX: t, b, p and h for top,
64 // bottom, page, and here, respectively. On top of that
65 // there is a new type, H, which does not really correspond
66 // to a float, since it means: put it "here" and nowhere else.
67 // Note, however that the H specifier is special and, because
68 // of implementation details cannot be used in the second
69 // argument of \newfloat.
70 // ext - The file name extension of an auxiliary file for the list
71 // of figures (or whatever). LaTeX writes the captions to
73 // within - This (optional) argument determines whether floats of this
74 // class will be numbered within some sectional unit of the
75 // document. For example, if within is equal to chapter, the
76 // floats will be numbered within chapters.
78 // style - plain, boxed, ruled
79 // \floatname{float}{floatname}
82 // \floatplacement{float}{placement}
85 // \restylefloat{float}
87 // \listof{type}{title}
90 // ¹ the algorithm float is defined using the float.sty package. Like this
92 // \newfloat{algorithm}{htbp}{loa}[<sect>]
93 // \floatname{algorithm}{Algorithm}
95 // The intention is that floats should be definable from two places:
97 // - the "gui" (i.e. by the user)
100 // This should only be done for floats defined in a documentclass and that
101 // does not need any additional packages. The two most known floats in this
102 // category is "table" and "figure". Floats defined in layout files are only
103 // stored in lyx files if the user modifies them.
106 // There should be a gui dialog (and also a collection of lyxfuncs) where
107 // the user can modify existing floats and/or create new ones.
109 // The individual floats will also have some settable
110 // variables: wide and placement.
116 // this should not be hardcoded, but be part of the definition
117 // of the float (JMarc)
