Most of the user interface to <TeXmacs> is dynamically created from within
|
2012-08-11 05:29:34 +08:00
|
|
|
the interpreted <scheme> code. New menus and buttons can be added, or the
|
2012-04-07 20:02:10 +08:00
|
|
|
existing ones reused and rearranged, even the main editor can be embedded
|
|
|
|
|
anywhere.
|
|
|
|
|
|
|
|
|
|
Imagine you want to implement some feature which requires interaction with
|
|
|
|
|
the user. One possible approach is to use the facility <scm|interactive>,
|
|
|
|
|
which according to the user's preferences will either popoup a dialog or
|
|
|
|
|
ask in the footer bar, based in metadata you provide inside your
|
2012-08-11 05:29:34 +08:00
|
|
|
<scm|tm-define>'d function. See ``<hlink|Meta information and logical
|
|
|
|
|
programming|../overview/overview-meta.en.tm>'' for more on this topic.
|
|
|
|
|
However, automatically generated content is not always the best approach,
|
|
|
|
|
so you might want to explicitly design your interface placing it inside a
|
|
|
|
|
complicated dialog. The following sections should help you with this.
