Re-enabling the WSJT-X i18n facilities. This allows translation files
to be created for languages that are automatically used to lookup
translatable strings. To enable a new language the language name must
be added to the CMakeLists.txt LANGUAGES list variable in BCP47 format
(i.e. en_US, en_GB, pt_PT, ...). Do one build with the CMake option
UPDATE_TRANSLATIONS enabled (do not leave it enabled as there is a
danger of loosing existing translated texts), that will create a fresh
translations/wsjtx_<lang>.ts file which should be immediately checked
in with the CMakeLists.txt change. The .ts should then be updated by
the translator using the Qt Linguist tool to add translations. Check
in the updated .ts file to complete the initial translation process
for that language.
To aid translators their WIP .ts file may be tested by releasing
(using the lrelease tool or from the Linguist menu) a .qm file and
placing that .qm file in the current directory before starting
WSJT-X. The translations will be used if the system locale matches the
file name. If the system locale does not match the file name; the
language may be overridden by setting the LANG environment variable.
For example if a wsjtx_pt_PT.qm file is in the current directory
WSJT-X will use it for translation lookups, regardless of the current
system locale setting, if the LANG variable is set to pt_PT or pt-PT.
On MS Windows from a command prompt:
set LANG=pt_PT
C:\WSJT\wsjtx\bin\wsjtx
elsewhere:
LANG=pt_PT wsjtx
changes on the C++ side. Basically works except that Tx audio has
incorrect DT and audio is truncated at the end. Also, command line
decoding using JT9 is not as sensitive as decoding from within WSJT-X.
Where tool tips are defined in rich text, equivalent pain test
accessible descriptions have been added so that screen readers do not
announce HTML tags.
Refactored date time delegates to use a simpler default editor via a
default item editor factory for QDateTime values, the editor is a
standard QDateTimeEdit with a format that includes seconds and renders
assuming the time is UTC.
Modified the Cabrillo log and Fox log database table models to provide
QDateTime items for the edit role of date time fields, and formated
date time strings including seconds and assumed as UTC for the display
role.
When RR73 is received we log the QSO, turn "Call 1st" OFF, and call CQ again.
Also, allow Alt+C and F6 (the latter only if altenrate F1-F6 bindings
are active) to toggle "Call 1st" ON/OFF.
