我在使用PushButton3.hide(); 或TTextLabel1.hide(); 语句的时候总是出现错误:../test/test.ui.h:12: request for member `hide' in `this->test:ushButton3',
which is of non-aggregate type `QPushButton*'
或
../test/test.ui.h:12: request for member `hide' in `this->test::TextLabel1',
which is of non-aggregate type `QLabel*'
请问是为什么?[PushButton3.show();也一样.]
