A couple of things I’ve noted.  Microsoft Message Analyzer uses tabs in the 
main window but I confess I don’t think I’ve used them to look at multiple 
traces.

Second point, maybe dockable windows would be better.  We use Telerik for 
Workbench and it provides a typical dockable window mechanism.  This meets both 
needs.  If you dock one window on top of another you get tabs.  Or you can 
undock a window and move it to another monitor.  By the way, I’m not promoting 
Telerik here, just using it for illustration.

Best regards…Paul

I think before we submit this patch, we should agree on a general UI concept 
going forward.

TL;DR: I think tabs for the main window is the wrong approach and will alienate 
a lot of users


There are basically three main uses for tabs in an application (besides from 
preference dialogs).

The first approach is your basic webbrowser, who displays multiple webpages in 
each individual tab. This actually is something Apple tries to enforce anyway 
and others do as well, but always the content of the tabs are similar. It is 
always a webcontent or a textdocument, .... They can be opened and closed 
individually and do not care about or influence each other. The Wireshark 
equivalent would be a capture file. IO Graph and the packet list do influence 
each other deeply, as does the packet list and every other dialog.

Now in the second approach (e.g. iTunes or music player application), you may 
have tabs which present you the same data in a different method  (Album, 
Artists, Playlist, ...). In these cases the tabs are always present, their view 
can be toggled, but in reality they are always there. Equivalent in Wireshark 
would be, that all dialogs are generated on capture file load and be always 
there, but hidden.

If tabs are not used for the main window, the usually are being used as utility 
tabs (see your favorite IDE e.g. QtCreator, Visual Studio, Eclipse, ...). This 
would be the third approach. They present additional information to the main 
document, a search possibility, graphical representation, ....

Wireshark's dialogs do not present different, independant data (first 
approach), but in the most cases an aggregated view (third approach) and 
sometimes an alternative view (second approach). Therefore, making them tabs to 
the main window is contradictory (as stated above). Users would have a program 
which operates very different to other programs they use daily. Making dialogs 
tabs to a utility window (byte view, packet detail) seems more to be the 
natural method. And then they can be dockable as well.

One last (but important) argument is screen size. A lot of people have big 
screens now. The tabbed approach for the main window really only makes sense on 
smaller screens. On a big screen tabs do not lead to a better utilisation of 
the space, making the work with a lot of tabs more cumbersome.

They do.  One instance in RAM mapped into the virtual address space of any 
process referencing the DLL.

On most if not all UN*Xes, the executable image's code and read-only data, and 
libwireshark's/libwiretap's/libwsutil's code and read-only data, should be 
shared between all of the processes.

You won't, however, share the results of reading in configuration files, e.g. 
the new fields added by reading in the RADIUS and DIAMETER dictionaries...

...unless they're read in by the UI process, and handed to the dissector 
processes as (read-only) shared memory.

I *think* Windows DLLs may also function as shared libraries.
