/**
The Fl_Browser widget displays a scrolling list of text
lines, and manages all the storage for the text. This is not a text
editor or spreadsheet! But it is useful for showing a vertical list of
named objects to the user.
<P>Each line in the browser is identified by number. <I>The numbers
start at one</I> (this is so that zero can be reserved for &quot;no line&quot; in
the selective browsers). <I>Unless otherwise noted, the methods do not
check to see if the passed line number is in range and legal. It must
always be greater than zero and &lt;= size().</I></P>
<P>Each line contains a null-terminated string of text and a void *
data pointer. The text string is displayed, the void *
pointer can be used by the callbacks to reference the object the text
describes. </P>
<P>The base does nothing when the user clicks on it. The
subclasses
Fl_Select_Browser,
Fl_Hold_Browser, and
Fl_Multi_Browser react to user clicks to select lines in
the browser and do callbacks. </P>
<P>The base called
Fl_Browser_ provides the scrolling and selection mechanisms of
this and all the subclasses, but the dimensions and appearance of each
item are determined by the subclass. You can use Fl_Browser_
to display information other than text, or text that is dynamically
produced from your own data structures. If you find that loading the
browser is a lot of work or is inefficient, you may want to make a
subof Fl_Browser_.

/** \fn Fl_File_Chooser::Fl_File_Chooser(const char *pathname, const char *pattern, int type, const char *title)
The constructor creates the Fl_File_Chooser dialog pictured
above. The pathname argument can be a directory name or a
complete file name (in which case the corresponding file is highlighted
in the list and in the filename input field.)
<P>The pattern argument can be a NULL
string or "*" to list all files, or it can be a
series of descriptions and filter strings separated by tab
characters (\t). The format of filters is either
"Description text (patterns)" or just "patterns". A file chooser
that provides filters for HTML and image files might look like:
<UL><PRE>
"HTML Files (*.html)\tImage Files (*.{bmp,gif,jpg,png})"
</PRE></UL>
<P>The file chooser will automatically add the "All Files (*)"
pattern to the end of the string you pass if you do not provide
one. The first filter in the string is the default filter.
<P>See the FLTK documentation on fl_filename_match()
for the kinds of pattern strings that are supported.
<P>The type argument can be one of the following:
<UL>
<LI>SINGLE - allows the user to select a
single, existing file.
<LI>MULTI - allows the user to select one
or more existing files.
<LI>CREATE - allows the user to select a
single, existing file or specify a new filename.
<LI>DIRECTORY - allows the user to select a
single, existing directory.
</UL>
<P>The title argument is used to set the title bar text for the
Fl_File_Chooser window.
