错误请教 [复制链接]

.我做程序编译时出现错误
..\tmp\dialogbilling.o(.text+0x6c):dialogbilling.cpp: undefined reference to `vtable for PK_DialogBilling'
..\tmp\dialogbilling.o(.text+0x73):dialogbilling.cpp: undefined reference to `vtable for PK_DialogBilling'

请问是怎么回事？主要我发现在dialogbilling.h文件中去掉Q_OBJECT就可以编译通过，但该文件中定义的槽却不起作用

是不是要手动moc一下?然后把moc好的文件在源程序尾include一下。具体怎么做baidu吧。
