库.xls.xlsx读写平台Qt Xlsx❌✔️✔️✔️跨平台xls✔️❌❌✔️跨平台libxls✔️❌❌✔️跨平台libXL✔️✔️✔️✔️跨平台ActiveX✔️✔️✔️✔️Windows原生qtXLS✔️❌✔️✔️WindowsBasicExcel✔️❌✔️✔️WindowsNumber Duck✔️❌✔️✔️WindowsLinux 本文采用基于 Windows 的 ActiveX 对象在 Qt 中也就是 QAxObjcet 实现读写 Excel 表。
2. QAxObject 简介 在介绍 QAxObject 之前首先简单了解一下 Windows 上的 COM 组件对象模型COM 是一个独立于平台的分布式面向对象的系统用于创建可以交互的二进制软件组件。 COM 是 Microsoft 的 OLE (复合文档的基础技术) 和 ActiveX (支持 Internet 的组件) 技术。可以使用各种编程语言创建 COM 对象。 面向对象的语言如 C提供了简化 COM 对象的实现的编程机制。 这些对象可以位于单个进程中、其他进程中甚至在远程计算机上也是如此。
COM 组件模型对象相信介绍可查看https://download.csdn.net/download/qq_36393978/88268235 而在 Qt 中的 QAxObject 是对 COM 组件模型对象的封装QAxObject 派生自QAxBaseQAxBase 提供了一组 API 通过 IUnknown 指针直接访问 COM 对象具体结构如下图。 而在 Windows 上的 Excel 也是一个这样的 COM 对象因此可以采用在 Qt 中使用 QAxObjcet 实现对 Excel 的操作其基本的操作流程如下 如上图描述了 Excel 的层次结构Excel.Application 对象 → WorkBooks 对象 → WorkBook 对象 → WorkSheet 对象 → Range 对象1 个 excel 有一个 Application 对象1 个 Application 对象有多个 Workbook 对象组成这些 Workbook 对象由 Workbooks 对象统一管理Workbook 对象下包含若干个 WorkSheet这些 WorkSheet 对象由 WorkSheets 对象统一管理WorkSheet 下面的 Range 对象对应这 WorkSheet 里面的表格单元了。箭头表示获取其子对象获取方式需调用 querySubObject() 函数获取子对象实例各个子对象调用 dynamicCall() 函数执行对各自的具体操作。
3. 基本使用方法
3.1. 包含相关文件 要使用 QAxObject 首先要在 .pro 文件中添加其模块名称 axcontainer这样工程文件在编译的时候就会加载该模块。
// project.pro
QT axcontainer在头文件中需要包含如下几个头文件
#include QString
#include QFileDialog
#include QAxObject
#include QVariant
#include QVariantList3.2. 创建 Excel 进程获取 Excel 工作簿集
打开文件夹选择 Excel 文件创建 Excel 进程
// 打开文件夹
QString strFilePathName QFileDialog::getOpenFileName(this, QStringLiteral(选择Excel文件),, tr(Exel file(*.xls *.xlsx)));
if(strFilePathName.isNull()) {return ;
}
QAxObject *excel new QAxObject(this)if (excel-setControl(Excel.Application)) { // 加载 Microsoft Excel 控件
} else {excel-setControl(ket.Application); // 加载 WPS Excel 控件
}excel-setProperty(Visible, false); // 不显示 Excel 窗体
QAxObject* workBooks excel-querySubObject(WorkBooks); //获取工作簿集合
workBooks-dynamicCall(Open(const QString), strFilePathName); //打开打开已存在的工作簿
QAxObject* workBook excel-querySubObject(ActiveWorkBook); //获取当前工作簿3.3. 获取电子表格集
每个 Excel 工作簿中都可以包含若干电子表格 Sheet
QAxObject* sheets workBook-querySubObject(Sheets); //获取工作表集合Sheets也可换用WorkSheets获取需要操作的工作表
QAxObject* sheet workBook-querySubObject(WorkSheets(int), 1);//获取工作表集合的工作表1即sheet13.4. 选取需要操作的单元格范围
每页电子表格包含多个单元格在操作之前需要选取所要操作的单元格范围 选取当前页面所有已使用单元格
//获取该sheet的使用范围对象一般读取 Excel 时会选取全部范围
QAxObject* usedRange sheet-querySubObject(UsedRange); 选取指定范围的单元格
//获取 sheet 的指定范围一般写入数据时会选取指定范围
QAxObject* usedRange sheet-querySubObject(Range(const QString), A1:C12);这里的 A1:C12 则表示选取A 到 C 列的 1~12 行单元格若写成 A1:A12 则表示选取A 列的 1~12 行单元格当然你也可以写成 A1:A1 则表示只选取 A1 这一个单元格。
选择指定单元格
//获取 sheet 的指定范围一般修改数据时会选取指定单元格
QAxObject* usedRange sheet-querySubObject(Range(QVariant,QVariant), A6);这里的 A6则表示选取 A6 这个单元格。
[注]获取 UsedRange 操作将会得到一个动态创建 (new) 出来的对象。
3.5. 读取单元格范围内容 当选取好要操作的单元各范围后那么这里介绍如何读取选取范围内所有的单元格内容
QVariant var usedRange-dynamicCall(Value);
delete usedRange;需要注意的是上文代码中除了获取单元格范围 (UsedRange) 操作之外其余得到的都是该对象的引用不会占用内存空间不需要释放而获取单元格适用范围 (UsedRange) 则得到一个 new 出来新分配的对象因此在读取或写入操作结束后需要手动释放该对象。 QVariant 类是一个数据联合体用来存放读取到的 Excel 数据。而事实上通过调用 dynamicCall(Value) 读到的数据类型是 QListQListQVariant 类型的因此要将读到的 var 转换为该类型的数据。
QListQListQVariant xls_data;QVariantList varRows var.toList();
if (varRows.isEmpty()) {return;
}const int rowCount varRows.size();
this-excel.rowCount rowCount;QVariantList rowData;for (int i 0; i rowCount; i){rowData varRows[i].toList();if (rowData.count() this-excel.columnCount) {this-excel.columnCount rowData.count();}this-xls_data.push_back(rowData);
}
3.6. 将读取到的数据用 QTableView 展示出来 这里的 TbleView_table1 是在 Forms 中的直接拖拽的 QTableView 控件。
QStandardItemModel *tab_model;
for (int i 0; i xls_data.count(); i) {for (int j 0; j xls_data.at(i).count(); j) {QStandardItem *item new QStandardItem(QString(xls_data.at(i).at(j).toByteArray()));tab_model-setItem(i, j, item);//delete item;}
}
this-ui-TbleView_table1-setModel(tab_model);3.7. 向选取的单元格范围写入数据 想必各位也注意到了在 Excel 中横轴坐标都是用 A~Z 字母表示为了与纵轴的表示方式区别开来而我们在操作是常用的则是以数字形式或者说在设置循环中用数字方式更为方便因此这里需要实现一个数字转 Excel 横坐标的函数如下。
QString ExcelProcess::to26AlphabetString(int data)
{QChar ch (QChar)(data 0x40);//A对应0x41return QString(ch);
}void ExcelProcess::convertToColName(int data, QString res)
{Q_ASSERT(data 0 data 65535);int tempData data / 26;if (tempData 0) {int mode data % 26;convertToColName(mode, res);convertToColName(tempData, res);} else {res(to26AlphabetString(data) res);}
}按照指定行、列一行一行的添加要写入的数据。
QListQListQVariant data_total;int row 50 - 30, col 100 - 10; // 表示选取范围为30~50 行10~100 列for (int i 0; i row; i) {QListQVariant data_row;for (int j 0; j col; j) {data_row.append(ImagineMiracle);}data_total.append(QVariant(data_row));
}
QString row_s, row_e, col_s, col_e, targetRange;
convertToColName(30, row_s);
convertToColName(50, row_e);
convertToColName(10, col_s);
convertToColName(100, col_e);
targetRange col_s row_s : col_e row_e ;QAxObject* sheet workBook-querySubObject(WorkSheets(int), 1);//获取工作表集合的工作表1即sheet1QAxObject* usedRange sheet-querySubObject(Range(const QString), target);
usedRange-setProperty(NumberFormat, ); // 设置所有单元格为文本属性
usedRange-dynamicCall(SetValue(const QVariant, QVariant(data_total));
workBook-dynamicCall(Save()); // 保存文件
delete usedRange;3.8. 退出操作 当执行完所有操作后需要关闭并退出 Excel代码如下
workBook-dynamicCall(Close()); //关闭工作簿
excel-dynamicCall(Quit()); //退出进程delete excel;4. 示例演示 下面是笔者写的一个简单的 Excel 表操作的代码其功能包含 1.打开并读取 Excel 表内容; 2.根据指定表格中数据的范围计算范围内数据量并写入表格; 3.根据数据量计算数据的所在范围。
