Building with enhanced clang warnings indicated a large number of
instances with the warning:
`warning: zero as null pointer constant`
Recommended practice in C++11 is to use `nullptr` as value for
a NULL or empty pointer value. All instances where this warning
was encountered were corrected in this commit.
Where warning was encountered in dependency code (i.e. external library)
no chnages were made. Patching will be offered upstream.
Building on #1874, commit adds user controls to choose
or edit style in cppcheck-gui ONLY. Commit does not
address CodeEditor style usage in triage app at this time.
Code Editor style can be altered from the added "Code Editor"
tab in the user preferences. The user has the option to select
default light, default dark, or to customize.
If user leaves the style set to light or dark defaults, this
will be reflected in the choices shown in the preferences
dialog.
User choice for Code Editor Style is saved in the cppcheck-gui
preferences under the heading "EditorStyle".
*Add context menu entry for copying selected log entry
*Add context menu entry for copying the complete log
*Do not show context menu if analysis log is empty
*Renamed function log_clear to logClear so it matches the coding style
in the GUI
- Moved setting from "Advanced" to "General" tab
-> Moved remaining single item, too, as it does not make sense to keep a tab for a single option. This option is now shown at the bottom of the dialog
- Replaced [inconclusive] string in "Summary" Column by extra column "Inconclusive", which is only visible if inconclusive checking is enabled
Added Print... and Print Preview... actions to main window
Added PrintableReport responsible for formatting of ErrorItems and
exposing of a QTextDocument that can be used for printing
If user tried to save results after re-checking files and not
getting new results by the re-check, the save was failed since
Cppcheck thought there were no results. This was caused by wrong
clearing of "has results" flag when removing single items from
the results.
Ticket: #4121 (Bogus error message when saving the report)
