qt4 .uc 转成 .h .cpp 文件

代码如下：

untitled.ui   用QT Designer做界面生成代码文件*.ui

ui_untitled.h   再用命令：uic ui_untitled.ui> ui_untitled.h 生成*.h文件

main.cpp  自写一个main.cpp程序工程文件

Quote:

#include
#include "dlg.h"//加载*.h文件

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    MyDlg *mydlg= new MyDlg;//建立类
    return mydlg->exec();
}

dlg.h    写一个dlg类的类文件

Quote:

#ifndef DLG_H
#define DLG_H

#include       //引用类库
#include "ui_untitled.h"  //引用界面头文件

class MyDlg: public Qdialog   //定义自己的类库
{
Q_OBJECT
public:
    MyDlg();  //构建函数
private slots:
    void InsertSlot();  //定义Slot
private:
    Ui::Form ui;  //定义ui命名空间 form类 ui
};

#endif

dlg.cpp  写一个dlg的程序文件

Quote:

#include "dlg.h"   //引用定义类头文件
#include
#include
MyDlg::MyDlg()  //构建类本身
{
    ui.setupUi(this);  //界面
    QObject::connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(InsertSlot()));  //建事件联接
}

void MyDlg::InsertSlot()   //事件函数
{
    QString strInsert = ui.lineEdit->text();
    if (strInsert.isEmpty())
    {
        QMessageBox::warning(this, tr("Alert"),
                  tr("You have not input any character"),
                  tr("OK"));
        ui.lineEdit->setFocus();
    }
    else
    {
        ui.listWidget->addItem(strInsert);
        ui.lineEdit->clear();
    }
}

原始文件为：untitled.ui, main.cpp, dlg.h, dlg.cpp
运行下面命令：编译
