I recommend you simply start working, on your own branch.
Either you clone the qtbase.git repository (Qt 5) and make your own
modifications, make the class work integrated into QtCore 5.0, or you work
separately, on top of QtCore 5.0. Whichever is easiest for you.

TECTED_SIGNAL would be very beneficial.
Signals are always protected in Qt 4. In Qt 5, this may change.
What's a Q_PROTECTED_SLOT for you? And how is this different from "protected
slots:" ?

No problem. My KMail is configured to display the text portions of emails for

And note that the problem here isn't loading the right plugin with dlopen.
It's that the plugin has dependencies and those are loaded automatically.

If the constructor parses as URL-or-path, then on Windows it's definitely the
file path.
The question would be what to do on other systems if we parse as url-or-path.

KDE has a module in kded. That's unacceptable for Qt.

even worse than on ARM11. Only on the A9 is the performance acceptable.

itself.
The difficulty lies in writing single-precision code, as C and C++ have an
automatic promotion to double. More difficult than that is to write code that
operates on shorts, since promotion to int happens even more easily.

I think I could
the same ABI, experience has
shown that HP's aCC compiler is not entirely compatible with GCC. And GCC on
HP-UXi has never been tested by the Qt team, it was contributed by a user. But
HP-UXi would probably have the same solution as Solaris.

Qt Creator has a "pluginspec" XML file accompanying the plugins that describes
what the plugin is and does. KDE does the same with .desktop files and its own
binary cache of them (system configurarion cache, a.k.a. sycoca).

The System Information backend plugins should then be folded into the platform
plugin and the Lighthouse plugin, as appropriate.
The only problem with this is that this is an "I propose", not an "I will do".

is exactly the point that Stephen was trying to make: we need a way to
detect which plugins exist and what they do, plus this should be cached
somehow.
