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