38 // Some information about Minipages in LaTeX:
39 // A minipage is a complete miniversion of a page and can contain
40 // its own footnotes, paragraphs, and array, tabular, and multicols
41 // environments. However it cannot contain floats or \marginpar's,
42 // but it can appear inside floats.
44 // The minipage environment is defined like this:
46 // \begin{minipage}[pos][height][inner-pos]{width} <text> \end{minipage}
49 // pos [opt] = is the vertical placement of the box with respect
50 // to the text baseline, [c], [t] and [b].
51 // height [opt] = the height of the box
52 // inner-pos [opt] = the position of the text within the box.
53 // It can be t, c, b or s, if unspecified the value
55 // width = the width of the box
57 // In LyX we should try to support all these parameters, settable in a
59 // In this pop-up diallog it should also be possible to set all margin
60 // values that is usable in the minipage.
61 // With regard to different formats (like DocBook) I guess a minipage
62 // can be used there also. Perhaps not in the latex way, but we do not
63 // have to output "" for minipages.
