Qt 프로젝트의 다중 Ui

Question

Qt Creator에서 여러 Ui 폼을 만들고 링크하려면 어떻게해야합니까? 내 메인 윈도우에 버튼이 있고 싶습니다.이 버튼이 트리거되면 다른 버튼이 표시되기를 원합니다. 어떻게 할 수 있습니까?

1. MainWindow를

mainwindow2

내가 MAIN.CPP에서이 코드를 시도 :

나는 두 Qt는 양식 클래스가

#include "mainwindow.h" 
#include "mainwindow2.h" 
#include <QApplication> 

int main(int argc, char *argv[]) 
{ 
QApplication a(argc, argv); 
MainWindow w; 
w.show(); 
MainWindow2 w2; 
w2.show(); 

return a.exec(); 
} 

을하지만,이 오류가 발생합니다

main.obj:-1: error: LNK2019: unresolved external symbol "public: virtual __thiscall MainWindow2::~MainWindow2(void)" (??1MainWindow2@@UAE@XZ) referenced in function _main

main.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall MainWindow2::MainWindow2(class QWidget *)" (??0MainWindow2@@QAE@PAVQWidget@@@Z) referenced in function _main

release\testtest.exe:-1: error: LNK1120: 2 unresolved externals

slots을 살펴보고 기본 상호 작용을 원할 경우 otherUI.show()/otherUI.hide()를 사용하십시오. msdn에서와 here

When you created the project, you made the wrong choice of application type. When asked whether your project was a console application or a windows application or a DLL or a static library, you made the wrong chose windows application (wrong choice).

Go back, start over again, go to File -> New -> Project -> Win32 Console Application -> name your app -> click next -> click application settings.

For the application type, make sure Console Application is selected (this step is the vital step).

The main for a windows application is called WinMain, for a DLL is called DllMain, for a .NET application is called Main(cli::array ^), and a static library doesn't have a main. Only in a console app is main called main
