I am working on a patch that (finally) makes the default-qt-settings file obsolete. This initial template for the gui settings file is no longer needed after all default values are defined as constants or are dynamically determined at first startup or when using a QScintilla lexer for the first time.
I realized that the environment variable
OCTAVE_DEFAULT_QT_SETTINGS is tested at startup and if set, its value is taken as the location of the initial settings file. Is this variable used also outside of
run-octave or can it be safely removed?
