[Kmymoney-devel] Re: kMyMoneyAccountSelector - Q_PROPERTY

[Petr Bravenec]

Thanks. It works now. I do not want to touch KMyMoney sources so I extended 
kMyMoneyAccountSelector to my own class. Later the same I will do the same for 
kMyMoneyDateInput - now I use KDateWidget class where the Q_PROPERTY works. 

There is now only one disadvantage. The kMyMoneyAccountSelector is stored in 
libwidgets.a library so the object is staticaly linked in kmymoney and in my 
plugin, too. The kcm plugin is then more then five times bigger then kmm plugin 
itself. It would be better to have the kMyMoneyAccountSelector in shared 
library libkmm_widget.so.
