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:

    void progress0();

    void progress1();

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);

}
