现象:

D:\qtworkspace\build-atiqtc9-deskc9-Debug\debug\moc_mainwindow.cpp:117: error: undefined reference to `MainWindow::ShowMainWindow()'


case 6: _t->on_pushButton_testlib_clicked(); break;
case 7: _t->on_pushButton_4_clicked(); break;
case 8: _t->on_btn_exeNetDll_clicked(); break;
case 9: _t->ShowMainWindow(); break;

default: ;


原因: cpp 方法没有加上类::在前面.
----------------------------------------------


//MainWindow
void ShowMainWindow()




解决:
-------------


void MainWindow::ShowMainWindow()
