地址薄（一）

标签：qt

先定义头文件：address.h

#ifndef ADDRESSBOOK_H
#define ADDRESSBOOK_H

#include <QWidget>

QT_BEGIN_NAMESPACE
class QLabel;
class QLineEdit;
class QTextEdit;
QT_END_NAMESPACE

//! [class definition]
class AddressBook : public QWidget
{
    Q_OBJECT

public:
    AddressBook(QWidget *parent = 0);

private:
    QLineEdit *nameLine;
    QTextEdit *addressText;
};
//! [class definition]

#endif

#include <QtWidgets>
#include "addressbook.h"

//! [constructor and input fields]
AddressBook::AddressBook(QWidget *parent)
    : QWidget(parent)
{
    QLabel *nameLabel = new QLabel(tr("Name:"));
    nameLine = new QLineEdit;

    QLabel *addressLabel = new QLabel(tr("Address:"));
    addressText = new QTextEdit;
//! [constructor and input fields]

//! [layout]
    QGridLayout *mainLayout = new QGridLayout;
    mainLayout->addWidget(nameLabel, 0, 0);
    mainLayout->addWidget(nameLine, 0, 1);
    mainLayout->addWidget(addressLabel, 1, 0, Qt::AlignTop);
    mainLayout->addWidget(addressText, 1, 1);
//! [layout]

//![setting the layout]
    setLayout(mainLayout);
    setWindowTitle(tr("Simple Address Book"));
}
//! [setting the layout]

#include <QtWidgets>
#include "addressbook.h"

//! [main function]
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    AddressBook addressBook;
    addressBook.show();

    return app.exec();
}
//! [main function]

现在地址薄只能显示名字、地址的标签和编辑栏，还没有添加功能，需要进一步

修改。
