I hope asking this question here is okay.

Is there any way to access the instances of plugin-specific
classes like NCurses? It's in the public headers and everything
so I suppose it must be part of the public API, I just can't
get a pointer to the instance used in my application from the
YUI class or anywhere else. I already saw YUIPlugin has a

don't know how to access the YUIPlugin instance of my

Thank you very much in advance

Could you please explain better what you need? if you need to run
an application using ncurses just pass "--ncurses" to the command
line. You can also use into the application runInTerminal and
check the return value

Thanks for your reply and sorry for being imprecise.

What I *actually* want to do is change the NCurses color scheme
from inside my application because I don't like the predefined

So I had a look at /usr/include/yui/ncurses/NCurses.h and thought
I might do something like this to access the global style
attributes (after I've assured myself that the application is
running on NCurses somehow):

````` NCstyle st = NCurses::style(); `````

But of course, this doesn't compile ("undefined reference"),
because the plugin is not meant to be statically linked and only
becomes available at runtime.

That's why I figured I'd need access to YUIPlugin::locateSymbol or
something, but for that I need the instance of YUIPlugin that
actually refers to the loaded NCurses plugin (if it has been

And that's where I'm stuck.

Maybe (probably) your library isn't intended to be used this

Anyway, hope my intention is clearer now.


there is an article about changing the color scheme for ncurses YaST
which should provide needed info, see
