华清远见嵌入式学习——春节作业——2.12

本文主要是介绍华清远见嵌入式学习——春节作业——2.12，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

作业要求：

通过QT制作一个模仿微信主界面的界面（不要求实现具体通信功能）

作业答案：

home.h

#ifndef HOME_H
#define HOME_H#include <QWidget>namespace Ui {
class HOME;
}class HOME : public QWidget
{Q_OBJECTpublic:explicit HOME(QWidget *parent = nullptr);~HOME();public slots:void dump();private slots:void on_Exitbtn_clicked();void on_Sendbtn_clicked();void on_clearbtn_clicked();private:Ui::HOME *ui;
};#endif // HOME_H

#ifndef LOGIN_H
#define LOGIN_H#include <QWidget>
#include <QMessageBox>QT_BEGIN_NAMESPACE
namespace Ui { class Login; }
QT_END_NAMESPACEclass Login : public QWidget
{Q_OBJECTpublic:Login(QWidget *parent = nullptr);~Login();signals:void dump();private slots:void on_pushButton_2_clicked();void on_pushButton_clicked();private:Ui::Login *ui;
};
#endif // LOGIN_H

home.cpp

#include "home.h"
#include "ui_home.h"HOME::HOME(QWidget *parent) :QWidget(parent),ui(new Ui::HOME)
{this->setWindowFlag(Qt::FramelessWindowHint);//去掉窗口头部this->setAttribute(Qt::WA_TranslucentBackground);//去掉窗口其他部分ui->setupUi(this);
}HOME::~HOME()
{delete ui;
}//界面跳转处理槽函数
void HOME::dump()
{this->show();
}//退出按钮
void HOME::on_Exitbtn_clicked()
{this->close();
}//发送按钮
void HOME::on_Sendbtn_clicked()
{ui->listWidget->addItem(ui->lineEdit->text());ui->lineEdit->clear();
}//清空按钮
void HOME::on_clearbtn_clicked()
{ui->listWidget->clear();}

#include "login.h"
#include "ui_login.h"Login::Login(QWidget *parent): QWidget(parent), ui(new Ui::Login)
{ui->setupUi(this);this->setWindowFlag(Qt::FramelessWindowHint);//去掉窗口头部this->setAttribute(Qt::WA_TranslucentBackground);//去掉窗口其他部分
}Login::~Login()
{delete ui;
}//X号按钮
void Login::on_pushButton_2_clicked()
{this->close();
}//登录按钮
void Login::on_pushButton_clicked()
{if(ui->accountLE->text() == "admin" && ui->PasswordLE->text() == "123456"){QMessageBox::information(this,"","登录成功!");ui->accountLE->text().clear();ui->PasswordLE->text().clear();emit dump();this->close();}else{QMessageBox::information(this,"","登录失败，请重试");ui->accountLE->text().clear();ui->PasswordLE->text().clear();}
}

main.cpp

#include "login.h"
#include "home.h"#include <QApplication>int main(int argc, char *argv[])
{QApplication a(argc, argv);Login w;w.show();HOME h;QObject::connect(&w,&Login::dump,&h,&HOME::dump);return a.exec();
}
