Follow-up Comment #76, bug #53276 (project octave):
@Torsten, @Rik: Attached is a new changeset version that should fix the
terminal color background. It's actually a simple fix once I realized what
was happening, but it isn't a general fix which I'm not sure is possible. I
added a portion of the cascading style sheet in
diff --git a/libgui/qterminal/libqterminal/unix/QUnixTerminalImpl.cpp

void QUnixTerminalImpl::setForegroundColor (const QColor& color)

Perhaps that negates the widget's QPalette::Window role, I don't know or if it
even matters. There is a FIXME comment just above the function I altered, so
Torsten may want to review that hunk.
I suppose this is what "cascading" is about, but the reason one can't do
something general at the octave_dock_widget level (which is what
autoFillBackground
http://doc.qt.io/archives/qt-4.8/qwidget.html#autoFillBackground-prop
is doing) is that one sort of needs to know the object class type. If I just
grab the background color from QDockWidget's perspective:
QPalette widgypal = widget()->palette();
QColor widgycol = widgypal.color(QPalette::Window);
I don't know if that QDockWidget is holding a TerminalView object, so one
would be setting the TerminalView background in a CSS description that is the
wrong color. In some sense, the cascading style sheet is like virtual
functions (the compiler/Qt resolves them) except that in the CSS case all
levels are applied as opposed to over-riding. We could attempt a generalized
approach by somehow grabbing the widget() class type and injecting that class
name in the octave_dock_widget level. However, I think that is a rather
sophisticated algorithm along the lines of Qt's autoFillBackground algorithm.
