#include "widget.h"

Widget::Widget(QWidget *parent)
    : QWidget(parent)
{
    //窗口
    this->setFixedSize(550,650);    //锁定窗口大小
    this->setWindowTitle("Devil May Cry 5");    //窗口标题
    this->setWindowIcon(QIcon("C:\\Users\\20723\\Pictures\\Saved Pictures\\th (1).jpg"));   //窗口图标

    //LOGL
    QLabel *lab3 = new QLabel(this);    //定义标签，依附在界面上
    lab3->resize(550,340);
    lab3->setPixmap(QPixmap("C:\\Users\\20723\\Pictures\\Saved Pictures\\OIP-C.jpg"));  //标签图标
    lab3->setScaledContents(true);  //图标自适应

    //LOGL
    QLabel *lab4 = new QLabel(this);    //定义标签，依附在界面上
    lab4->resize(550,310);
    lab4->setPixmap(QPixmap("C:\\Users\\20723\\Pictures\\Saved Pictures\\OIP-C (1).jpg"));  //标签图标
    lab4->setScaledContents(true);  //图标自适应
    lab4->move(0,340);

    //登录按钮
    QPushButton *btn1 = new QPushButton("登录", this);    //定义“登录”按钮，依附在界面上
    btn1->setIcon(QIcon("C:\\Users\\20723\\Pictures\\Saved Pictures\\icon\\login.png"));    //按钮图标
    btn1->resize(120,50);
    btn1->move(160,320);

    //取消按钮
    QPushButton *btn2 = new QPushButton("取消", this);    //定义“取消”按钮，依附在界面上
    btn2->setIcon(QIcon("C:\\Users\\20723\\Pictures\\Saved Pictures\\icon\\cancel.png"));   //按钮图标
    btn2->resize(120,50);
    btn2->move(btn1->x()+140,btn1->y());

    //账户图标
    QLabel *lab1 = new QLabel(this);    //定义标签，依附在界面上
    lab1->resize(50,40);
    lab1->move(120,180);
    lab1->setPixmap(QPixmap("C:\\Users\\20723\\Pictures\\Saved Pictures\\icon\\userName.jpg")); //标签图标

    //密码图标
    QLabel *lab2 = new QLabel(this);    //定义标签，依附在界面上
    lab2->resize(50,40);
    lab2->move(lab1->x(),lab1->y()+75);
    lab2->setPixmap(QPixmap("C:\\Users\\20723\\Pictures\\Saved Pictures\\icon\\passwd.jpg"));   //标签图标
    lab2->setScaledContents(true);  //图标自适应

    //账户行
    QLineEdit *edit1 = new QLineEdit(this); //定义行编辑器，依附在界面上
    edit1->setPlaceholderText("if you want it");
    edit1->resize(240,40);
    edit1->move(lab1->x()+65,lab1->y());

    //密码行
    QLineEdit *edit2 = new QLineEdit(this); //定义行编辑器，依附在界面上
    edit2->setPlaceholderText("then you'll have to take it");
    edit2->resize(240,40);
    edit2->move(lab2->x()+65,lab2->y());
    edit2->setEchoMode(QLineEdit::Password);    //设置密码回显模式
