if (and only if) the length of the item being added is 0 (so that it has
no data backing it).
This means the data stream name pointer for the item in question is
null; make sure we handle that.
Use that for some "uses the value from the matching request" fields in
the SMB Pipe protocol.

a "Match Selected" on it - we can't do a "Match Selected" if the field
has no value (e.g., FT_NULL) and has a length of 0.
If we unselect the current packet, we don't have a protocol tree, so we
don't have a currently selected field - clear the "Match Selected" menu
item and the display in the status line of information about the
currently selected field.
Move the low-level statusbar manipulation into "gtk/main.c", in routines
whose API doesn't expose anything GTK+-ish.
"close_cap_file()" calls one of those routines to clear out the status
bar, so it doesn't need to take a pointer to the statusbar widget as an
argument.
"clear_tree_and_hex_views()" is purely a display-manipulating routine;
move it to "gtk/proto_draw.c".
Extract from "tree_view_unselect_row_cb()" an "unselect_field()" routine
to do all the work that needs to be done if the currently selected
protocol tree row is unselected, and call it if the currently selected
packet list row is unselected (if it's unselected, there *is* no
protocol tree, so no row can be selected), as well as from
"tree_view_unselect_row_cb()".
Before pushing a new field-description message onto the statusbar, pop
the old one off.
Get rid of an unused variable (set, but not used).

1. Fix an off-by-one error when finding the field. This only showed up
if the selected byte had no field of its own and was only designated
as part of the parent protocol (like the 00-padding at the beginning of
TCP options).
2. Fix an off-by-one error when clicking on a character in the second
half of the "text dump" portion of the hex dump. I forgot about the
extra space between the first 8 characters and the second 8 characters.

routines need it.
When a user clicks on a hex digit or on the corresponding character
(the "text dump" portion) in the hex dump, find the field in the
proto_tree that the byte corresponds to, expand the GtkCTree so that
the field is viewable, select the field, and center it vertically.
LanAlyzer has this feature, and I've missed it in Ethereal.

that automatic scrolling of the hex pane continues to work, but without

the user may edit it afterwards, or may use the aforementioned dialog
box to construct a filter not in the list).

may be redrawing a packet window that displays a frame other than the
current frame; give it arguments to specify the raw frame data and
"frame_data" structure for the frame.
This requires that each packet window have, associated with it, a
pointer to the "frame_data" structure; that replaces the "cap_len" and
"encoding" fields in a "PacketWinData" structure, as those are just
copies of fields from the frame's "frame_data" structure.
"packet_hex_print()" needn't be passed both the start and length values
from a "field_info" structure - just pass it a pointer to that
structure, or NULL for "no field is selected in the packet". It also
needn't, any longer, be passed the "cap_len" and "flags.encoding" fields
of a "frame_data" structure - just pass it a pointer to that structure.
In "redraw_hex_dump_all()", don't redraw the hex dump pane of the main
window if there is no current frame.

"cancel", and "delete" methods, give them:
"fetch" - fetch from the notebook tab any values not already
stored in "prefs", and store them there, but doesn't apply them;
"apply" - apply the settings in "prefs";
"destroy" - clean up any windows created from the tab.
As we no longer have "cancel" methods, we don't have per-preference code
to revert preference values; instead, we have the common preference
dialog box code make a copy of all the current preferences, and, when
the "Cancel" button is clicked, free the current preferences and copy
the saved preferences to it, and apply the preferences.
Add an "Apply" button to the preference dialog box, which applies the
current preferences without closing the dialog box.
Treat a request to delete the preferences dialog box as equivalent to
clicking "Cancel".
Have a "remember_ptree_widget()" routine to remember all protocol tree
widgets, and use the list of those widgets when we set GUI preferences
for the protocol tree widgets, rather than setting the main protocol
tree widget and then using the list of packet windows. Move that code
out of "main.c" to "proto_draw.c", as it's not used by anything in
"main.c", but is used by stuff in "proto_draw.c".
Make the font one of the preferences we can set on the fly for protocol
tree widgets. Also make it something we can set on the fly for the
packet list widget.

speaking, "isgraph()", which came later, is defined to be "isprint()

the "Follow TCP Stream" displays; that means we can use the same GTK+
calls to set the scrollbar placement on them that is used to set it on
other widgets.
Keep a list of all the GtkScrolledWindows whose scrollbar placement we
control with the GUI preference item for that, and change them all when
the GUI preference item is changed (which means that the GUI preference
item now applies to the "Follow TCP Stream" window as well as to the
hex/ASCII panes).

I did this:
First, Havoc Pennington, in "GTK+/Gnome Application Development", in
Appendix seciton A.3.88, recommends using GtkCTree instead of GtkTree
because GtkCtree is faster, and GtkTree has limitation on its total row
height: since it must fit inside a GdkWindow, it is limited to 32,768
pixels of height. GtkTree is more flexible with regards to the types of
widgets that can be placed in the tree, but since we deal only with text,
that doesn't matter, at least for now.
Secondly, a GtkTree doesn't allow arrow-key navigation (at least as far
as I could tell). It always bothered me that the up and down arrow keys
worked in the packet list and in the hex dump, but no in the protocol tree.
GtkCTree does allow arrow-key navigation. In fact, GtkCTree is a subclass
of GtkCList (the packet list widget), so they behave a lot alike.
I went ahead and fixed the selection bar which has been bothering Richard
for a long time now. :) In the GUI preferences dialogue, you can now set
both the packet list selection bar and the protocol tree selection bar
to either "browse" or "select" mode. "browse" mode is what you're used to:
the arrow keys move an outline of the selection bar, but do not change
the selection. "select" mode does change the selection when the arrow keys
are pressed. The default behavior is set to "select", which seems more
natural for a first-time user.

dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:
obviates the need to update "packet.h" whenever you add a new
subtree type - you only have to add a call to
"proto_register_subtree_array()" to a "register" routine and an
array of pointers to "ett_", if they're not already there, and
add a pointer to the new "ett_" variable to the array, if they
are there;
would allow run-time-loaded dissectors to allocate subtree types
when they're loaded.
