Qt工作笔记-QTableWidget插入QcomboBOx后，如何获取数据

话不多说，运行图如下：

代码如下：

widget.h

#ifndef WIDGET_H #define WIDGET_H#include <QWidget> #include <QComboBox> #include <QStringList> #include <QMessageBox>namespace Ui { class Widget; }class Widget : public QWidget {Q_OBJECTpublic slots:void pressBtn();public:explicit Widget(QWidget *parent = 0);~Widget();private:Ui::Widget *ui; };#endif // WIDGET_H

widget.cpp

#include "widget.h" #include "ui_widget.h"Widget::Widget(QWidget *parent) :QWidget(parent),ui(new Ui::Widget) {ui->setupUi(this);ui->tableWidget->setColumnCount(3);ui->tableWidget->setColumnWidth(0,150);QStringList combobox1_list;combobox1_list.append(tr("comboBox11"));combobox1_list.append(tr("comboBox12"));combobox1_list.append(tr("comboBox13"));combobox1_list.append(tr("comboBox14"));QComboBox *combobox1=new QComboBox();combobox1->addItems(combobox1_list);ui->tableWidget->insertRow(0);ui->tableWidget->setCellWidget(0,1,combobox1);QTableWidgetItem *headItem1=new QTableWidgetItem();ui->tableWidget->setItem(0,0,headItem1);ui->tableWidget->item(0,0)->setText(tr("点击此处进行选择行"));QStringList combobox2_list;combobox2_list.append(tr("comboBox21"));combobox2_list.append(tr("comboBox22"));combobox2_list.append(tr("comboBox23"));combobox2_list.append(tr("comboBox24"));QComboBox *combobox2=new QComboBox();combobox2->addItems(combobox2_list);ui->tableWidget->setCellWidget(0,2,combobox2);QStringList combobox3_list;combobox3_list.append(tr("comboBox31"));combobox3_list.append(tr("comboBox32"));combobox3_list.append(tr("comboBox33"));combobox3_list.append(tr("comboBox34"));QComboBox *combobox3=new QComboBox();combobox3->addItems(combobox3_list);ui->tableWidget->insertRow(1);ui->tableWidget->setCellWidget(1,1,combobox3);QTableWidgetItem *headItem2=new QTableWidgetItem();ui->tableWidget->setItem(1,0,headItem2);ui->tableWidget->item(1,0)->setText(tr("点击此处进行选择行"));QStringList combobox4_list;combobox4_list.append(tr("comboBox41"));combobox4_list.append(tr("comboBox42"));combobox4_list.append(tr("comboBox43"));combobox4_list.append(tr("comboBox44"));QComboBox *combobox4=new QComboBox();combobox4->addItems(combobox4_list);ui->tableWidget->setCellWidget(1,2,combobox4);//ui->tableWidget->item(1,0)->setText(tr("点击此处进行选择行"));connect(ui->pushButton,SIGNAL(clicked(bool)),this,SLOT(pressBtn()));}void Widget::pressBtn(){int rowNum=ui->tableWidget->currentRow();QString msg;for(int i=1;i<ui->tableWidget->columnCount();i++){QWidget *widget=ui->tableWidget->cellWidget(rowNum,i);QComboBox *combox=(QComboBox*)widget;msg=msg.append(combox->currentText())+" ";}QMessageBox::information(this,tr("提示"),msg); }Widget::~Widget() {delete ui; }

main.cpp

#include "widget.h" #include <QApplication>int main(int argc, char *argv[]) {QApplication a(argc, argv);Widget w;w.show();return a.exec(); }
