The default behaviour was to select the tab to the right of the
closed tab which is not very useful for us since the right tab
will be the Logs tab.
Fixes#331
This is done for all top level windows - ports, stats, logs
At startup, the local portgroup would automatically become current with
the result that the welcome page would not be visible. Not sure why but
an explicit setFocus of ports window seems to avoid it.
* All 3 icons are combined into a single row instead of 3 separate rows
* Tooltip to clarify meaning of icons
* Qt Model-View displays icon left-aligned, so use a custom delegate to
center-align it
* Add a icon for "Transmit On"
* Edit icons for "Start/Stop Capture"
This makes it more readable. Unfortunately, the alternate row colors
don't apply to the row headers. QHeaderView is supposed to support
QBackgroundRole but there's a long pending bug on the Qt side for the
same - https://bugreports.qt.io/browse/QTBUG-31804
* Enable button only when one or more port is selected
* Reorder the button to make it first in the stats group
* Show some helpful text instead of a blank window when no stream stats
are available
- Automatic full column selection
- Enable/Disable toolbar buttons based on selection
- Code refactoring to avoid unncessary selectedColumns computation
PortStats and StreamStats Windows are presented as a tabbed widget.
Multiple StreamStats windows are titled to include an id to hint at the
sequence in which they were opened
