QT程序“用户基本资料修改”的功能表单,第1张

用到布局管理器将d出的d窗分成三个部分并往里面加入东西。

基本信息页面：

联系方式页面：

详细资料页面：

 

所使用的软件为 QT5.12.12，下载网站为Index of /archive/qt/5.12https://download.qt.io/archive/qt/5.12/新建Qt Widgets Application,自己取一个项目名称，基类选QDialog，类（class）命名为Content，取消创建界面的 复选框选中状态。

1.导航页的实现  "content.h"中的代码为

#ifndef CONTENT_H
#define CONTENT_H

#include 
#include 
#include 
#include 
#include "baseinfo.h"
#include "contact.h"
#include "detail.h"
class Content : public QFrame
{
    Q_OBJECT

public:
    Content(QWidget *parent = nullptr);
    ~Content();
    QStackedWidget *stack;
    QPushButton *AmendBtn;
    QPushButton *CloseBtn;
    BaseInfo *baseInfo;
    Contact *contact;
    Detail *detail;
};
#endif // CONTENT_H

 Content.cpp中的代码为

#include "content.h"
#include 
#include 
Content::Content(QWidget *parent)
    : QFrame(parent)
{
    stack =new QStackedWidget(this);//创建一个QStackedWidget对象
    stack->setFrameStyle(QFrame::Panel|QFrame::Raised);//对堆栈窗口的显示风格进行设置
    /*插入三个页面*/
    baseInfo = new BaseInfo();
    contact = new Contact();
    detail = new Detail();
    stack->addWidget(baseInfo);
    stack->addWidget(contact);
    stack->addWidget(detail);
    /*创建两个按钮*/
    AmendBtn =new QPushButton(tr("修改"));
    CloseBtn = new QPushButton(tr("关闭"));//创建这两个按钮
    QHBoxLayout *BtnLayout =new QHBoxLayout;
    BtnLayout->addStretch(1);
    BtnLayout->addWidget(AmendBtn);
    BtnLayout->addWidget(CloseBtn);
    /*进行整体布局*/
    QVBoxLayout *RightLayout = new QVBoxLayout(this);
    RightLayout->setMargin(10);
    RightLayout->setSpacing(6);
    RightLayout->addWidget(stack);
    RightLayout->addLayout(BtnLayout);
}

Content::~Content()
{
}

 上面的代码是先创建一个有两个按钮的空页面d窗，而且将页面分割。然后需要为子页面里面添加内容。在项目的文件夹上面点击鼠标右键。选择Add New

 然后d出的d窗选择“C++ Class”，点击“Choose”。d出的d窗在“Base class”下拉列表框中选择基类名为“QWidget”，在“Class name”的文本框中输入“BaseInfo”，（意思是修改用户基本信息的子页面），点击下一步，点击完成。同样的方法，再创建两个， *** 作方式其他都一样。只有一个不一样，就是类名（Class name）不一样，第二个为“Contact”，（意思是显示用户的联系方式的子页面），第三个为“Detail”，（意思是显示用户详细资料的子页面）。

打开baseinfo.h。添加下面的代码：

#ifndef BASEINFO_H
#define BASEINFO_H

#include 
#include 
#include 
#include 
#include 
#include 
#include 
class BaseInfo : public QWidget
{
    Q_OBJECT
public:
    explicit BaseInfo(QWidget *parent = nullptr);

signals:


public slots:
private:
    //左侧
    QLabel *UserNameLabel;
    QLabel *NameLabel;
    QLabel *SexLabel;
    QLabel *DepartmentLabel;
    QLabel *AgeLabel;
    QLabel *OtherLabel;
    QLineEdit *UserNameLineEdit;
    QLineEdit *NameLineEdit;
    QComboBox *SexComboBox;
    QTextEdit *DepartmentTextEdit;
    QLineEdit *AgeLineEdit;
    QGridLayout *LeftLayout;
    //右侧
    QLabel *HeadLabel;
    QLabel *HeadIconLabel;
    QPushButton *UpdateHeadBtn;
    QHBoxLayout *TopRightLayout;
    QTextEdit *IntroductionTextEdit;
    QLabel *IntroductionLabel;
    QVBoxLayout *RightLayout;

};

#endif // BASEINFO_H

打开baseinfo.cpp，添加如下代码：

#include "baseinfo.h"

BaseInfo::BaseInfo(QWidget *parent) : QWidget(parent)
{
    /*左侧*/
    UserNameLabel = new QLabel("用户名：");
    UserNameLineEdit =new QLineEdit;
    NameLabel =new QLabel("姓名：");
    NameLineEdit =new QLineEdit;
    SexLabel =new QLabel("性别：");
    SexComboBox =new QComboBox;
    SexComboBox->addItem("女");
    SexComboBox->addItem("男");
    DepartmentLabel =new QLabel("部门：");
    DepartmentTextEdit =new QTextEdit;
    AgeLabel =new QLabel("年龄：");
    AgeLineEdit =new QLineEdit;
    OtherLabel = new QLabel("备注：");
    OtherLabel->setFrameStyle(QFrame::Panel|QFrame::Sunken);
    LeftLayout =new QGridLayout();
    LeftLayout->addWidget(UserNameLabel,0,0);
    LeftLayout->addWidget(UserNameLineEdit,0,1);
    LeftLayout->addWidget(NameLabel,1,0);
    LeftLayout->addWidget(NameLineEdit,1,1);
    LeftLayout->addWidget(SexLabel,2,0);
    LeftLayout->addWidget(SexComboBox,2,1);
    LeftLayout->addWidget(DepartmentLabel,3,0);
    LeftLayout->addWidget(DepartmentTextEdit,3,1);
    LeftLayout->addWidget(AgeLabel,4,0);
    LeftLayout->addWidget(AgeLineEdit,4,1);
    LeftLayout->addWidget(OtherLabel,5,0,1,2);
    LeftLayout->setColumnStretch(0,1);
    LeftLayout->setColumnStretch(1,3);
    /*右侧*/
    HeadLabel =new QLabel("头像");//右上角部分
    QSize picSize(150,100);
    QPixmap icon("IMG_1751(20220430-120124).JPG");
    QPixmap newIcon = icon.scaled(picSize,Qt::KeepAspectRatio,Qt::SmoothTransformation);
    HeadIconLabel = new QLabel();
    HeadIconLabel->setPixmap(newIcon);
    /*HeadIconLabel =new QLabel;
    QPixmap icon("312.png");
    HeadIconLabel->setPixmap(icon);
    HeadIconLabel->resize(icon.width(),icon.height());*/
    UpdateHeadBtn =new QPushButton("更新");
    TopRightLayout =new QHBoxLayout();
    TopRightLayout ->setSpacing(20);
    TopRightLayout->addWidget(HeadLabel);
    TopRightLayout->addWidget(HeadIconLabel);
    TopRightLayout->addWidget(UpdateHeadBtn);
    IntroductionLabel =new QLabel("个人说明：");//右下角部分
    IntroductionTextEdit =new QTextEdit;
    RightLayout =new QVBoxLayout();
    RightLayout->setMargin(10);
    RightLayout->addLayout(TopRightLayout);
    RightLayout->addWidget(IntroductionLabel);
    RightLayout->addWidget(IntroductionTextEdit);
    /***********/
    QGridLayout *mainLayout =new QGridLayout(this);
    mainLayout->setMargin(15);
    mainLayout->setSpacing(10);
    mainLayout->addLayout(LeftLayout,0,0);
    mainLayout->addLayout(RightLayout,0,1);
    mainLayout->setSizeConstraint(QLayout::SetFixedSize);

}

打开contact.h。添加如下代码：

#ifndef CONTACT_H
#define CONTACT_H

#include 
#include 
#include 
#include 
#include 
class Contact : public QWidget
{
    Q_OBJECT
public:
    explicit Contact(QWidget *parent = nullptr);

signals:


public slots:
private:
    QLabel *EmailLabel;
    QLineEdit *EmailLineEdit;
    QLabel *AddrLabel;
    QLineEdit *AddrLineEdit;
    QLabel *CodeLabel;
    QLineEdit *CodeLineEdit;
    QLabel *MoviTelLabel;
    QLineEdit *MoviTelLineEdit;
    QCheckBox *MoviTelCheckBook;
    QLabel *ProTelLabel;
    QLineEdit *ProTelLineEdit;
    QGridLayout *mainLayout;


};

#endif // CONTACT_H

打开contact.cpp ，添加如下代码：

#include "contact.h"

Contact::Contact(QWidget *parent) : QWidget(parent)
{
    EmailLabel =new QLabel("电子邮件：");
    EmailLineEdit =new QLineEdit;
    AddrLabel =new QLabel("联系地址：");
    AddrLineEdit =new QLineEdit;
    CodeLabel =new QLabel("邮政编码：");
    CodeLineEdit =new QLineEdit;
    MoviTelLabel =new QLabel("移动电话：");
    MoviTelLineEdit =new QLineEdit;
    MoviTelCheckBook =new QCheckBox("接收留言：");
    ProTelLabel =new QLabel("办公电话：");
    ProTelLineEdit =new QLineEdit;
    mainLayout =new QGridLayout(this);
    mainLayout->setMargin(15);
    mainLayout->setSpacing(10);
    mainLayout->addWidget(EmailLabel,0,0);
    mainLayout->addWidget(EmailLineEdit,0,1);
    mainLayout->addWidget(AddrLabel,1,0);
    mainLayout->addWidget(AddrLineEdit,1,1);
    mainLayout->addWidget(CodeLabel,2,0);
    mainLayout->addWidget(CodeLineEdit,2,1);
    mainLayout->addWidget(MoviTelLabel,3,0);
    mainLayout->addWidget(MoviTelLineEdit,3,1);
    mainLayout->addWidget(MoviTelCheckBook,3,2);
    mainLayout->addWidget(ProTelLabel,4,0);
    mainLayout->addWidget(ProTelLineEdit,4,1);
    mainLayout->setSizeConstraint(QLayout::SetFixedSize);

}

打开detail.h，添加：

#ifndef DETAIL_H
#define DETAIL_H

#include 
#include 
#include 
#include 
#include 
#include 

class Detail : public QWidget
{
    Q_OBJECT
public:
    explicit Detail(QWidget *parent = nullptr);

signals:

public slots:
private:
    QLabel *NationalLabel;
    QComboBox *NationalComboBox;
    QLabel *ProvinceLabel;
    QComboBox *ProvinceComboBox;
    QLabel *CityLabel;
    QLineEdit *CityLineEdit;
    QLabel *IntroductLabel;
    QTextEdit *IntroductTextEdit;
    QGridLayout *mainLayout;

};



#endif // DETAIL_H

打开detail.cpp，添加：

#include "detail.h"

Detail::Detail(QWidget *parent) : QWidget(parent)
{
    NationalLabel =new QLabel("国家/地址：");
    NationalComboBox =new QComboBox;
    NationalComboBox->insertItem(0,("中国"));
    NationalComboBox->insertItem(1,("美国"));
    NationalComboBox->insertItem(2,("英国"));
    ProvinceLabel =new QLabel("省份：");
    ProvinceComboBox = new QComboBox;
    ProvinceComboBox->insertItem(0,("江苏省"));
    ProvinceComboBox->insertItem(1,("山东省"));
    ProvinceComboBox->insertItem(2,("浙江省"));
    CityLabel =new QLabel("城市：");
    CityLineEdit = new QLineEdit;
    IntroductLabel = new QLabel("个人说明：");
    IntroductTextEdit = new QTextEdit;
    mainLayout = new QGridLayout(this);
    mainLayout->setMargin(15);
    mainLayout->setSpacing(10);
    mainLayout->addWidget(NationalLabel,0,0);
    mainLayout->addWidget(NationalComboBox,0,1);
    mainLayout->addWidget(ProvinceLabel,1,0);
    mainLayout->addWidget(ProvinceComboBox,1,1);
    mainLayout->addWidget(CityLabel,2,0);
    mainLayout->addWidget(CityLineEdit,2,1);
    mainLayout->addWidget(IntroductLabel,3,0);
    mainLayout->addWidget(IntroductTextEdit,3,1);

}

最后编写主函数：打开所在文件的 main.cpp文件，添加：

#include "content.h"

#include 
#include 
#include 
#include 
#include 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QFont font("AR PL KaitiM GB",12); //设置整个程序采用的字体与字号
    a.setFont(font);
    //新建一个水平分割窗口对象，作为主布局框
    QSplitter *splitterMain =new QSplitter(Qt::Horizontal,0);
    splitterMain->setOpaqueResize(true);
    QListWidget *list=new QListWidget(splitterMain); //
    list->insertItem(0,QObject::tr("基本信息"));
    list->insertItem(1,QObject::tr("联系方式"));
    list->insertItem(2,QObject::tr("详细资料"));
    Content *content =new Content(splitterMain);//插入Content对象
    QObject::connect(list,SIGNAL(currentRowChanged(int)),content->stack,SLOT(setCurrentIndex(int)));
    //设置主布局框即水平分割窗口的标题
    splitterMain->setWindowTitle(QObject::tr("修改用户资料"));
    //设置主布局框即水平分割窗口的最小尺寸
    splitterMain->setMinimumSize(splitterMain->minimumSize());
    //设置主布局框即水平分割窗口的最大尺寸
    splitterMain->setMaximumSize(splitterMain->maximumSize());
    splitterMain->show();  //显示主布局框，其上面的控件一同显示
    //Content w;
    //w.show();
    return a.exec();
}

这些文件都在同一个项目下面
