QTableWidget 设置头标签

要设置QTableWidget的标题，可以通过调用setHorizontalHeaderLabels(const QStringList & labels)来设置。labels中存放的是所有要显示为标题的内容。

Example:本例主要是以实现一个简单的输出窗口为例

//输出窗口头文件代码：

#ifndef OUTPUT_H#define OUTPUT_H//#include "qgridview.h"#include <QWidget>class COutput : public QWidget{    Q_OBJECTpublic:    explicit COutput(QWidget *parent = 0);    signals:    public slots:       };#endif // OUTPUT_H

//输出窗口实现文件代码：

#include "output.h"

#include <QGridLayout>

#include <QLabel>

#include <QTableWidgetItem>

#include <QTableWidget>

#include <QHBoxLayout>

#include <QHeaderView>

COutput::COutput(QWidget *parent) :

    QWidget(parent)

{

    //QGridView *gridview = new QGridView();

    QTableWidget *tableWidget = new QTableWidget(this);

    tableWidget->setColumnCount(2);

    tableWidget->setColumnWidth(0, 350);

    tableWidget->setColumnWidth(1, 700);

    QStringList strList;

    QString strDesc(tr("描述"));

    QString strLoca(tr("位置"));

    strList.push_back(strDesc);

    strList.push_back(strLoca);

    //set the horizontal title

    tableWidget->setHorizontalHeaderLabels(strList);

    //set the alignment way

    tableWidget->horizontalHeader()->setDefaultAlignment(Qt::AlignLeft);

    QHBoxLayout *layout = new QHBoxLayout;

    layout->addWidget(tableWidget);

    this->setLayout(layout);

}

//main.cpp 内容如下：

#include "mainwindow.h"//#include "toolkit.h"#include <QApplication>#include <QDockWidget>#include "output.h"#include <QTextEdit>int main(int argc, char *argv[]){    QApplication a(argc, argv);    //MainWindow w;    //w.show();    QMainWindow * wnd = new QMainWindow;    QTextEdit *txtEdit = new QTextEdit;    wnd->setCentralWidget(txtEdit);    COutput *pOutput = new COutput;    if(NULL == pOutput)    {        return 1;    }    QDockWidget *outputDock = new QDockWidget();    if(NULL == outputDock)    {        return 1;    }    outputDock->setWindowTitle("输出");    outputDock->setAllowedAreas(Qt::AllDockWidgetAreas);    outputDock->setWidget(pOutput);    wnd->addDockWidget(Qt::BottomDockWidgetArea, outputDock);    wnd->show();        return a.exec();}
