QT 如何在其他cpp文件中调用Mainwindow中的单文本框

MainWindow w2;

QString Starttime = w2.starttime->text();
QString Endtime= w2.endtime->text();
报错信息如下:
src/plot.cpp: In member function 'void Plot::saveToFile()':
src/plot.cpp:222: error: invalid use of incomplete type 'struct QLineEdit'
src/plot.h:17: error: forward declaration of 'struct QLineEdit'
src/plot.cpp:223: error: invalid use of incomplete type 'struct QLineEdit'
src/plot.h:17: error: forward declaration of 'struct QLineEdit'
