Wireshark · Ethereal-dev: Re: [Ethereal-dev] Saving all packets between the first and the last marked packet

[Dick Gooris <gooris@xxxxxxxxxx>]

Ulf,

Thanks again for this. I have seen the loop in the print_dlg.c and i am 
using the same now in the file_dlg.c, indeed *very* fast. I honestly did 
not expect that. I added the marker stuff in there to calculate the 
range between the lowest and highest value.

I took the suggestions in the current code, but made a minor change in 
the 'Selected packet only' widget. I am writing : 'Selected packet #6 
only'   where 6 is the current selected packet - of course :-)    Just 
tell me if this is nicer or should we stick to the moreless hardcoded '1 
packet'.

I added again the screen shot of the current result, given that I marked 
4 packets. I took the screen shot when having my mouse pointer in the 
entry of the range. Therefore, the balloon help is taken with the shot 
as well.

I checked all the functionality, and it seem to work ok. I already 
spotted some opportunities for optimalizations, but this can be done later.

Indeed, the last thing to do is to change the counter values in case the 
'Apply display filter' is being set. Referring to the attached example, 
right now the value of 'All captured packets, 15 packets', remains the 
same when toggling the 'Apply display filter' check button.  I have been 
looking into the GTK world of functions, and found 
gtk_widget_modify_text(), but this is not known to my gtk library. I 
also do not know if this can be used for radio buttons anyway. So when 
toggeling the check button a function would then update the associated 
couters.

If you have some suggestion to alter the text info, this would be great.

I am going to send you the code separately, then you can also see/use 
the parser.

Best regards,

   - Dick Gooris
