QtableWidget 表头增加复选框简单实现方法

1.最近再开发一个批量查询上传的小工具，要增加一个批量选择的复选框，全选或者全不选；

QCheckBox *checkBox = new QCheckBox(ui.tableWidget);
        checkBox->resize(40, 24);
        ui.tableWidget->setCellWidget(0, 0, checkBox);
        checkBox->setStyleSheet("margin-left:4px;");//左侧的偏移量，不设置QCheckBox会紧靠左边，没有和下面的对齐；
        checkBox->setChecked(false);
        ui.tableWidget->setColumnWidth(0, 24);
        ui.tableWidget->setColumnWidth(1, 40);
        connect(checkBox, &QCheckBox::clicked, this, &signature::SelectAllFiles);

 

 

其他函数实现如下

#include "signature.h"
#include "MultiFileDirDialog.h"
#include <QFileInfoList>
#include "curl.h"
#include<QProcess>
#include <QMessageBox>
#include <QCheckBox>
#pragma execution_character_set("utf-8")
