Qt之QTableWidget基本操作和动态添加控件

概述：
此案例向大家分享tableWidget控件一切基本操作，比如表格禁止编辑、单击选中一行、动态添加表头、动态添加其他控件等等

代码示例：
.h

#ifndef MYTABLEWIDGET_H
#define MYTABLEWIDGET_H

#include <QWidget>
#include <QCheckBox>
#include <QPushButton>

namespace Ui {
class MyTableWidget;
}

class MyTableWidget : public QWidget
{
    Q_OBJECT

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

private:
    void initTableWidget();

private:
    Ui::MyTableWidget *ui;
};

#endif // MYTABLEWIDGET_H

.cpp

#include "MyTableWidget.h"
#include "ui_MyTableWidget.h"

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

MyTableWidget::~MyTableWidget()
{
    delete ui;
}

void MyTableWidget::initTableWidget()
{
    ui->tableWidget->setRowCount(5);    //设置行
    ui->tableWidget->setColumnCount(5); //设置列
    for(int i=0;i<6;i++)                //循环添加数据
    {
        ui->tableWidget->setItem(i,0,new QTableWidgetItem("hh"));//动态创建item插入据方便验证
        ui->tableWidget->setItem(i,1,new QTableWidgetItem("hh"));
        ui->tableWidget->setItem(i,2,new QTableWidgetItem("hh"));
        ui->tableWidget->setItem(i,3,new QTableWidgetItem("hh"));
        ui->tableWidget->setItem(i,4,new QTableWidgetItem("hh"));
    }
    QCheckBox *checkbox = new QCheckBox;         //动态创建个控件
    ui->tableWidget->setCellWidget(1,1,checkbox);//添加控件到tableWidget上
    QPushButton *button = new QPushButton("你好");
    ui->tableWidget->setCellWidget(2,2,button);


    ui->tableWidget->setStyleSheet("border: 0px solid black;");
    ui->tableWidget->setShowGrid(true);                                    //设置显示格子线
    ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);  //整行选中的方式
    ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);   //禁止编辑
    ui->tableWidget->horizontalHeader()->setStretchLastSection(true);      //行头自适应表
    ui->tableWidget->horizontalHeader()->setFont(QFont("song", 16));       //设置字体格式
    ui->tableWidget->verticalHeader()->setDefaultSectionSize(40);          //设置一行默认高度
    ui->tableWidget->verticalHeader()->setVisible(false);                  //隐藏列表头
    ui->tableWidget->horizontalHeader()->setVisible(false);                //隐藏行表头
    ui->tableWidget->item(4,4)->setTextColor(QColor(255,0,0));             //设置文字颜色
    ui->tableWidget->item(3,4)->setBackgroundColor(QColor(255,0,255));     //设置背景颜色
    ui->tableWidget->item(2,2)->setTextAlignment(Qt::AlignCenter | Qt::AlignVCenter);//设置字体居中显示
    QStringList header;                                                    //动态添加表头
    header<<"票号"<<"状态"<<"打印次数"<<"发车时间"<<"票价";
    ui->tableWidget->setHorizontalHeaderLabels(header);
    ui->tableWidget->clearContents();                                      //清除表格内容不清除表头
}
