QT5在VS2012中使用Qt Designer創建的UI文件與類相關聯的問題

        在MFC中，新建了一個資源對話框後，只需要Ctrl+W後，可以生成與該對話框相關聯的類。但是在VS2012+QT5的組合開發中，在添加了一個新的ui文件後，如何生成一個類與之對應呢？

1，在Qt5中的QtDesigner中生成了一個基於QDialog或者QWidget的界面ui中，編譯後，就出現了相應的一個ui_文件名.h的文件，以這userinforDlg.ui爲例，簡單介紹一下：在Qt Designer設計器下生成了這樣的一個ui文件。

這個ui生成的頭文件爲ui_userinforDlg.h

/********************************************************************************

    } // retranslateUi

};

namespace Ui {
    class UserInforDialog: public Ui_UserInforDialog {};
} // namespace Ui

QT_END_NAMESPACE

#endif // UI_USERINFORDLG_H

其實這個頭文件是Qt Designer自動生成的，我們在設計好了ui後，編譯一下，這個文件就生成了。

2.我們需要手動添加一個類與這個ui關聯。

#ifndef MYUSERINFORDLG_H
#define MYUSERINFORDLG_H

#include <QDialog>
#include "ui_userinforDlg.h"
namespace Ui
{
 class UserInforDialog;
};
class MyUserInforDlg : public QDialog
{
 Q_OBJECT

public:
 MyUserInforDlg(QWidget *parent);
 ~MyUserInforDlg();

private:
 Ui::UserInforDialog *ui;
};

#endif // MYUSERINFORDLG_H

以上是myuserinfordlg.h文件

#include "myuserinfordlg.h"

MyUserInforDlg::MyUserInforDlg(QWidget *parent)
 : QDialog(parent), ui(new Ui::UserInforDialog)
{
 ui->setupUi(this);
}

MyUserInforDlg::~MyUserInforDlg()
{
 delete ui;
}

以上是myuserinfordlg.cpp文件

這樣就把ui與類關聯起來了。

當然以上的這個類可以使用繼承。
