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