1、UI部分



2、DataManager.h

#ifndef DATAMANAGER_H
#define DATAMANAGER_H

#include <QWidget>
#include <QStandardItemModel>
#include <QKeyEvent>

namespace Ui {
class DataManager;
}

class DataManager : public QWidget
{
    Q_OBJECT

public:
    explicit DataManager(QWidget *parent = 0);
    ~DataManager();

private:
    Ui::DataManager *ui;

    QStandardItemModel* model;


private:
    void MessageEvent(const std::string& msg);
    void keyPressEvent(QKeyEvent *event);

private slots:
    void wholeScreen();//全屏
    void tableupdate();//更新界面
    void setting();//配置
};

#endif // DATAMANAGER_H

3、DataManager.cpp

#include "datamanager.h"
#include "ui_datamanager.h"
#include <QStringList>

DataManager::DataManager(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::DataManager)
{
    ui->setupUi(this);


    setWindowTitle("标题");

    model = new QStandardItemModel(this);

    QStringList header_text;
    header_text<<QStringLiteral("时间")<<QStringLiteral("数据列");
    model->setHorizontalHeaderLabels(header_text);
    ui->tableView->setModel(model);
    ui->tableView->horizontalHeader()->setStyleSheet("QHeaderView::section{font:15pt '微软雅黑';Height:35px;}");//设置表头字体，行高
    ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);//行选中
    //ui->tableView->setSelectionModel(QAbstractItemView::SingleSelection);//每次选中一行
    ui->tableView->horizontalHeader()->setVisible(true);//设置表头可见
    ui->tableView->horizontalHeader()->setStretchLastSection(true);//表头自适应，最后一列将会填充空白部分
   // ui->tableView->setWordWrap();

    connect(ui->m_fullscreen,SIGNAL(clicked()),this,SLOT(wholeScreen()));
    connect(ui->m_renovate,SIGNAL(clicked()),this,SLOT(tableupdate()));
    connect(ui->m_setting,SIGNAL(clicked()),this,SLOT(setting()));

}

DataManager::~DataManager()
{
    delete ui;
}
void DataManager::MessageEvent(const std::string& msg)
{

}
//全屏
void DataManager::wholeScreen()
{
    this->showFullScreen();
}
//更新界面
void DataManager::tableupdate()
{
    this->update();
}
//配置
void DataManager::setting()
{
    QWidget* new_widget = new QWidget();
    new_widget->show();
}
//按ESC退出全屏
void DataManager::keyPressEvent(QKeyEvent *event)
{
    if(event->key() == Qt::Key_Escape)
    {
        showMinimized();
    }
}
