Improve the alert boxes put up for file open/read/write errors. (Some
influence came from
http://developer.apple.com/techpubs/mac/HIGuidelines/HIGuidelines-232.html
which has a section on dialog box and alert box messages. However,
we're largely dealing with technoids, not with The Rest Of Us, so I
didn't go as far as one perhaps should.)
Unfortunately, it looks like it's a bit more work to arrange that, if
you give a bad file name to the "-r" flag, the dialog box pop up only
*after* the main window pops up - it has the annoying habit of popping
up *before* the main window pops up, and sometimes getting *obscured* by
it, when I do that. The removal of the dialog box stuff from
"load_cap_file()" was intended to facilitate that work. (It might also
be nice if, when an open from the "File/Open" menu item fails, we keep
the file selection box open, and give the user a chance to correct
typos, choose another file name, etc.)

Have "close_cap_file()" disable all menu items that make sense only if
you have a capture.
Leave the job of enabling and disabling menu items that make sense only
if you have a capture (except for "File/Save" and "File/Save As...", for
now) up to "load_cap_file()", "close_cap_file()", and the like - don't
scatter that stuff throughout the code.
Disable "File/Print Packet" if no packet is selected; enable it only if
a packet is selected.
If there's a selected packet, and a display filter is run:
if the selected packet passed the filter, re-select it;
if the selected packet didn't pass the filter, un-select it.
If we've opened a live "pcap" capture, but can't do the capture because
we can't get the netmask info, or can't parse the capture filter string,
or can't install the filter, close the live capture and the dump and
delete the dump file.
If we failed to open a live "pcap" capture, don't try to read the
capture file - it doesn't exist.

Have "close_cap_file()" disable all menu items that make sense only if
you have a capture.
Leave the job of enabling and disabling menu items that make sense only
if you have a capture (except for "File/Save" and "File/Save As...", for
now) up to "load_cap_file()", "close_cap_file()", and the like - don't
scatter that stuff throughout the code.
Disable "File/Print Packet" if no packet is selected; enable it only if
a packet is selected.
If there's a selected packet, and a display filter is run:
if the selected packet passed the filter, re-select it;
if the selected packet didn't pass the filter, un-select it.
If we've opened a live "pcap" capture, but can't do the capture because
we can't get the netmask info, or can't parse the capture filter string,
or can't install the filter, close the live capture and the dump and
delete the dump file.
If we failed to open a live "pcap" capture, don't try to read the
capture file - it doesn't exist.

Improve the alert boxes put up for file open/read/write errors. (Some
influence came from
http://developer.apple.com/techpubs/mac/HIGuidelines/HIGuidelines-232.html
which has a section on dialog box and alert box messages. However,
we're largely dealing with technoids, not with The Rest Of Us, so I
didn't go as far as one perhaps should.)
Unfortunately, it looks like it's a bit more work to arrange that, if
you give a bad file name to the "-r" flag, the dialog box pop up only
*after* the main window pops up - it has the annoying habit of popping
up *before* the main window pops up, and sometimes getting *obscured* by
it, when I do that. The removal of the dialog box stuff from
"load_cap_file()" was intended to facilitate that work. (It might also
be nice if, when an open from the "File/Open" menu item fails, we keep
the file selection box open, and give the user a chance to correct
typos, choose another file name, etc.)

Have "close_cap_file()" disable all menu items that make sense only if
you have a capture.
Leave the job of enabling and disabling menu items that make sense only
if you have a capture (except for "File/Save" and "File/Save As...", for
now) up to "load_cap_file()", "close_cap_file()", and the like - don't
scatter that stuff throughout the code.
Disable "File/Print Packet" if no packet is selected; enable it only if
a packet is selected.
If there's a selected packet, and a display filter is run:
if the selected packet passed the filter, re-select it;
if the selected packet didn't pass the filter, un-select it.
If we've opened a live "pcap" capture, but can't do the capture because
we can't get the netmask info, or can't parse the capture filter string,
or can't install the filter, close the live capture and the dump and
delete the dump file.
If we failed to open a live "pcap" capture, don't try to read the
capture file - it doesn't exist.

Improve the alert boxes put up for file open/read/write errors. (Some
influence came from
http://developer.apple.com/techpubs/mac/HIGuidelines/HIGuidelines-232.html
which has a section on dialog box and alert box messages. However,
we're largely dealing with technoids, not with The Rest Of Us, so I
didn't go as far as one perhaps should.)
Unfortunately, it looks like it's a bit more work to arrange that, if
you give a bad file name to the "-r" flag, the dialog box pop up only
*after* the main window pops up - it has the annoying habit of popping
up *before* the main window pops up, and sometimes getting *obscured* by
it, when I do that. The removal of the dialog box stuff from
"load_cap_file()" was intended to facilitate that work. (It might also
be nice if, when an open from the "File/Open" menu item fails, we keep
the file selection box open, and give the user a chance to correct
typos, choose another file name, etc.)
