Latest trunk allows you this if you include new syshelpers unit:
True.ToString; // True
True.ToTrueFalseString(scfUpperCase); // TRUE
True.ToString('OnState', 'OffState'); // OnState
True.ToString('Running', 'Stopped', scfUpperCase); // RUNNING
It also allows you to populate TBitFormatSettings with your strings for TRUE
and FALSE and gives you method CopyToDefaultBoolStrings. This changes boolean
to string text outputs in syshelpers and some other places. Maybe that could
fit your bill.

This looks like postgresql error msg (is it pgsql db ? ). It happens when
pgsql server db encoding != utf8 (unicode) and you're trying to insert
character which is untransatable by internal encoding funcions eg.
win1250toUTF8('something') (eg. double minus (or whatever name it have) sign
which can be found in ms word (it looks like double minus -- but in one
line)).

I've successfully built bindings and qtlcl apps for n9 (I guess that Joost also was succesfull). It works, but normal qtlcl app cannot change orientation so it's always horizontal. If you want to create really fancy n9 apps you need QtCreator (Nokia SDK). Besides that, N9 is normal linux machine (eg. X11) with arm processor (no need for QTOPIA defines in bindings like N900 needs). P.S: There's guy on #lazarus-ide irc channel nick = trx. He created complete api to work with nokia ui's,so you can create same app like with QtCreator (under Lazarus) ask him for more details. zeljko ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Wow, that's "something" ! :) Few years ago in age of Kylix 3 Andreas Hausladen builded C bindings for Qt3 via doxygen which created xml files and then small app builded bindings from that xml files - even virtual methods overriding was supported. So if someone have enough doxygen knowledge it is possible to create automatic C bindings with some efforts. zeljko ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Probably same way as our libQt4Pas.

This will be great Maybe it is possible (or will be possible) to use C++ class, but I don't see light at the end of tunnel for eg override virtual routine from such C++ class which is possible by C interface or howto attach callback (event) from pascal to C++.
