qt设置tablewidget颜色、添加选择框、添加按钮和进度条

添加选择框
在代码中设置tablewidget的样式表

setStyleSheet("QTableWidget{ color:black; \
                                 background-color:rgb(224,224,224);\
                                 selection-color:rgb(0, 0, 0); \
                                 selection-background-color:rgb(    100,149,237);\
                                 border:0px;\
                                 font: 8pt 'Microsoft YaHei' ;}""QHeaderView::section:horizontal{     /*设置标题(水平的)*/\
                                border: 1px solid rgb(255, 255, 255);     /*白色间隔*/\
                                border - bottom: 0px;/*下边框不需要颜色*/\
                                color: rgb(2, 65, 132);\
                                background: rgb(    100,149,237);\
                                padding - left: 2px;\
                                min - width:60px;}");

设置表格，添加选择框

//设置列数
     ui->tableWidget->setColumnCount(3);//设置行数
     ui->tableWidget->setRowCount(3);//设置整行选中
     ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);//表头标题
     QStringList headerText;
     headerText<<"序  号"<<"名  称"<<"选  择";
     ui->tableWidget->setHorizontalHeaderLabels(headerText);//设置列宽
     ui->tableWidget->setColumnWidth(0,ui->tableWidget->width()/3);
     ui->tableWidget->setColumnWidth(1,ui->tableWidget->width()/3);
     ui->tableWidget->setColumnWidth(2,ui->tableWidget->width()/3);//去除垂直表头
     ui->tableWidget->verticalHeader()->setVisible(false);//去除选中虚线框
     ui->tableWidget->setFocusPolicy(Qt::NoFocus);//禁止编辑
     ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);//添加项for(int i=0; i<3; i++){
         ui->tableWidget->setItem(i,0,new QTableWidgetItem(QString::number(i+1)));
         ui->tableWidget->setItem(i,1,new QTableWidgetItem("aaa"));//添加选择框
         QTableWidgetItem *check = new QTableWidgetItem();
         check->setCheckState(Qt::Unchecked);
         ui->tableWidget->setItem(i,2, check);//元素居中
         ui->tableWidget->item(i,0)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
         ui->tableWidget->item(i,1)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);
         ui->tableWidget->item(i,2)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);}

cellClicked事件响应，当点击表格项，对复选框进行选中和取消选择

void MainWindow::on_tableWidget_cellClicked(int row,int column){//判断选择状态if(ui->tableWidget->item(row,2)->checkState()== Qt::Checked){//设置选择状态
        ui->tableWidget->item(row,2)->setCheckState(Qt::Unchecked);}else{
        ui->tableWidget->item(row,2)->setCheckState(Qt::Checked);}}

添加进度条和按钮
设置表格

//设置列数
    ui->tableWidget->setColumnCount(3);//设置行数
    ui->tableWidget->setRowCount(2);//设置整行选中
    ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);//表头标题
    QStringList headerText;
    headerText<<"序  号"<<"按  钮"<<"进度条";
    ui->tableWidget->setHorizontalHeaderLabels(headerText);//设置列宽
    ui->tableWidget->setColumnWidth(0,ui->tableWidget->width()/3);
    ui->tableWidget->setColumnWidth(1,ui->tableWidget->width()/3);
    ui->tableWidget->setColumnWidth(2,ui->tableWidget->width()/3);//去除水平表头
    ui->tableWidget->verticalHeader()->setVisible(false);//去除选中虚线框
    ui->tableWidget->setFocusPolicy(Qt::NoFocus);//禁止编辑
    ui->tableWidget->setEditTriggers(QAbstractItemView::NoEditTriggers);//添加控件
    QPushButton *button0 = new QPushButton("按钮0");
    QPushButton *button1 = new QPushButton("按钮1");
    m_pProgress0 = new QProgressBar();
    m_pProgress1 = new QProgressBar();
    ui->tableWidget->setCellWidget(0,1,button0);
    ui->tableWidget->setCellWidget(0,2,m_pProgress0);
    ui->tableWidget->setCellWidget(1,1,button1);
    ui->tableWidget->setCellWidget(1,2,m_pProgress1);//添加项for(int i=0; i<2; i++){
        ui->tableWidget->setItem(i,0,new QTableWidgetItem(QString::number(i+1)));//元素居中
        ui->tableWidget->item(i,0)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);}

建立按钮和处理函数的信号槽连接，让按钮点击，进度条移动

//建立信号槽连接connect(button0,SIGNAL(clicked()),this,SLOT(progress0()));connect(button1,SIGNAL(clicked()),this,SLOT(progress1()));

槽函数和进度条控件

private slots:voidprogress0();voidprogress1();
private:
    Ui::MainWindow *ui;
    QProgressBar *m_pProgress0;
    QProgressBar *m_pProgress1;

void MainWindow::progress0(){
    m_pProgress0->setValue(m_pProgress0->value()+10);}void MainWindow::progress1(){

    m_pProgress1->setValue(m_pProgress1->value()+10);}
