c++ - Providing Q_PROPERTY in subclass of Q_OBJECT result in Error 1 -

-

i need solving following problem:

i have base class, derives qobject , has q_object macro. in class want subclass base class , provide properties use in qml (q_property).

but seems missing basic piece of information, because cannot going

baseclass:

#ifndef a_h #define a_h #include <qobject>  class a: public qobject {     q_object         q_property(qstring name read getname constant) ...

subclass:

#ifndef b_h #define b_h #include "classpath/a.h" class b: public {     q_object     q_property(qstring type read gettype write settype notify typechanged) ...

furthermore have registered type qml qmlregistertype<b>("customclasses",1,0,"b");

in qml file creating b item b{ type: "b" }

the error following: [debug/moc_b.cpp] error 1

not informative me , qt knowings

if remove q_object macro geht cannot assign non-existent property type

i hope 1 of can explain im doing wrong!

thanks in advance!

thanks hints! figured out forgot putvoid typechanged() under signals: pretty trivial in retrospect

thanks @ manni66! had no idea there more detailed compiler output in ide. led me correct solution.
