QtXlsx is a library that can read and write Excel files. It doesn't require Microsoft Excel and can be used in any platform that Qt5 supported. The library can be used to
- Generate a new .xlsx file from scratch
- Extract data from an existing .xlsx file
- Edit an existing .xlsx file
Getting Started
- For linux user, if your Qt is installed through package manager tools such "apt-get", make sure that you have installed the Qt5 develop package qtbase5-private-dev
Usage(1): Use Xlsx as Qt5's addon module
Building the module
Note: Perl is needed in this step.
-
Download the source code.
-
Put the source code in any directory you like
-
Go to top directory of the project in a terminal and run
qmake
make
make install
The library, the header files, and others will be installed to your system.
make html_docscan be used to generate documentations of the library, andmake checkcan be used to run unit tests of the library.
Using the module
- Add following line to your qmake's project file:
QT += xlsx
- Then, using Qt Xlsx in your code
#include <QtXlsx>
int main()
{
QXlsx::Document xlsx;
xlsx.write("A1", "Hello Qt!");
xlsx.saveAs("Test.xlsx");
return 0;
}
Usage(2): Use source code directly
The package contains a qtxlsx.pri file that allows you to integrate the component into applications that use qmake for the build step.
-
Download the source code.
-
Put the source code in any directory you like. For example, 3rdparty:
|-- project.pro
|-- ....
|-- 3rdparty
| |-- qtxlsx
| |
- Add following line to your qmake project file:
include(3rdparty/qtxlsx/src/xlsx/qtxlsx.pri)
Note: If you like, you can copy all files from src/xlsx to your application's source path. Then add following line to your project file:
include(qtxlsx.pri)
> **Note**: If you do not use qmake, you need to define the following macro manually
> ```
XLSX_NO_LIB
- Then, using Qt Xlsx in your code
#include "xlsxdocument.h"
int main()
{
QXlsx::Document xlsx;
xlsx.write("A1", "Hello Qt!");
xlsx.saveAs("Test.xlsx");
return 0;
}
在构建的时候，可能会有如下的错误，
xlsxzipreader.cpp: In member function ‘void QXlsx::ZipReader::init()’:
xlsxzipreader.cpp:51:66: error: conversion from ‘QVector<QZipReader::FileInfo>’ to non-scalar type ‘QList<QZipReader::FileInfo>’ requested
QList<QZipReader::FileInfo> allFiles = m_reader->fileInfoList();
这里只需要吧出错的文件添加 :
#include <QVector>
然后把出错的地方的"QList" 用"QVector" 替换掉重新构建就可以了。
对于Qt Xlsx （ QtXlsxWriter ） 的安装请参考：
http://blog.csdn.net/woshidahuaidan2011/article/details/52724452
这里主要介绍其基本的编程使用方法。
首先我们想到就是对xlsx文件进行读写，因此我们有如下的代码：
#include <QtCore>
#include "xlsxdocument.h"
#include "xlsxformat.h"
#include "xlsxcellrange.h"
#include "xlsxchart.h"
int main()
{
QXlsx::Document xlsx("book1.xlsx");/*打开一个book1的文件*/
QXlsx::Format format1;/*设置该单元的样式*/
format1.setFontColor(QColor(Qt::red));/*文字为红色*/
format1.setPatternBackgroundColor(QColor(152,251,152));/*北京颜色*/
format1.setFontSize(15);/*设置字体大小*/
format1.setHorizontalAlignment(QXlsx::Format::AlignHCenter);/*横向居中*/
format1.setBorderStyle(QXlsx::Format::BorderDashDotDot);/*边框样式*/
xlsx.write("A1", "Hello Qt!", format1);/*写入文字，应该刚才设置的样式*/
xlsx.write(2, 1, 12345, format1);/*写入文字，应该刚才设置的样式*/
QXlsx::Format format2;/*重新设置另一个单元的样式*/
format2.setFontBold(true);/*设置加粗*/
format2.setFontUnderline(QXlsx::Format::FontUnderlineDouble);/*下双划线*/
format2.setFillPattern(QXlsx::Format::PatternLightUp);/*填充方式*/
xlsx.write("A4", "=44+33", format2);/*写入文字，应该刚才设置的样式*/
xlsx.write("C4", true, format2);
xlsx.saveAs("book1.xlsx");/*保存*/
QXlsx::Document xlsx2("Book1.xlsx");/*复制book1到book2*/
xlsx2.saveAs("Book2.xlsx");
return 0;
}其运行效果如下：
接下来我们处理数据的是很多时候需要插入折线图、饼状图等等来图像化的处理数据，因此我们可以可以在原有代码上添加一段代码，使之添加一个sheet而且插入饼状图及其条形图：
#include <QtCore>
#include "xlsxdocument.h"
#include "xlsxformat.h"
#include "xlsxcellrange.h"
#include "xlsxchart.h"
int main()
{
QXlsx::Document xlsx("book1.xlsx");/*打开一个book1的文件*/
QXlsx::Format format1;/*设置该单元的样式*/
format1.setFontColor(QColor(Qt::red));/*文字为红色*/
format1.setPatternBackgroundColor(QColor(152,251,152));/*北京颜色*/
format1.setFontSize(15);/*设置字体大小*/
format1.setHorizontalAlignment(QXlsx::Format::AlignHCenter);/*横向居中*/
format1.setBorderStyle(QXlsx::Format::BorderDashDotDot);/*边框样式*/
xlsx.write("A1", "Hello Qt!", format1);/*写入文字，应该刚才设置的样式*/
xlsx.write(2, 1, 12345, format1);/*写入文字，应该刚才设置的样式*/
QXlsx::Format format2;/*重新设置另一个单元的样式*/
format2.setFontBold(true);/*设置加粗*/
format2.setFontUnderline(QXlsx::Format::FontUnderlineDouble);/*下双划线*/
format2.setFillPattern(QXlsx::Format::PatternLightUp);/*填充方式*/
xlsx.write("A4", "=44+33", format2);/*写入文字，应该刚才设置的样式*/
xlsx.write("C4", true, format2);
if(!xlsx.selectSheet("ziv")){/*在当前打开的xlsx文件中，找一个名字为ziv的sheet*/
xlsx.addSheet("ziv");//找不到的话就添加一个名为ziv的sheet
}
for (int i=10; i<20; ++i) {/*写入一串数字*/
xlsx.write(i, 1, i*i*i); //A10:A19
xlsx.write(i, 2, i*i); //B10:B19
xlsx.write(i, 3, i*i-1); //C10:C19
}
QXlsx::Chart *pieChart = xlsx.insertChart(3, 5, QSize(300, 300));/*在3行5列的位置插入一个图标*/
pieChart->setChartType(QXlsx::Chart::CT_Pie);/*插入一个饼形图*/
pieChart->addSeries(QXlsx::CellRange("A10:A19"));/*饼形图添加数据*/
pieChart->addSeries(QXlsx::CellRange("B10:B19"));
pieChart->addSeries(QXlsx::CellRange("C10:C19"));
QXlsx::Chart *barChart = xlsx.insertChart(3, 13, QSize(300, 300));/*在3行13列的位置插入一个图标*/
barChart->setChartType(QXlsx::Chart::CT_Bar);/*条形图*/
barChart->addSeries(QXlsx::CellRange("A10:C19"));/*给条形图加入数据*/
xlsx.saveAs("book1.xlsx");/*保存*/
QXlsx::Document xlsx2("Book1.xlsx");/*复制book1到book2*/
xlsx2.saveAs("Book2.xlsx");
return 0;
}
上面代码中运行效果如下：
很多时候我们还需要添加图表来美化表格，代码如下：
#include <QtCore>
#include <QtGui>
#include "xlsxdocument.h"
#include "xlsxformat.h"
#include "xlsxcellrange.h"
#include "xlsxchart.h"
int main()
{
QXlsx::Document xlsx("book1.xlsx");/*打开一个book1的文件*/
QXlsx::Format format1;/*设置该单元的样式*/
format1.setFontColor(QColor(Qt::red));/*文字为红色*/
format1.setPatternBackgroundColor(QColor(152,251,152));/*北京颜色*/
format1.setFontSize(15);/*设置字体大小*/
format1.setHorizontalAlignment(QXlsx::Format::AlignHCenter);/*横向居中*/
format1.setBorderStyle(QXlsx::Format::BorderDashDotDot);/*边框样式*/
xlsx.write("A1", "Hello Qt!", format1);/*写入文字，应该刚才设置的样式*/
xlsx.write(2, 1, 12345, format1);/*写入文字，应该刚才设置的样式*/
QXlsx::Format format2;/*重新设置另一个单元的样式*/
format2.setFontBold(true);/*设置加粗*/
format2.setFontUnderline(QXlsx::Format::FontUnderlineDouble);/*下双划线*/
format2.setFillPattern(QXlsx::Format::PatternLightUp);/*填充方式*/
xlsx.write("A4", "=44+33", format2);/*写入文字，应该刚才设置的样式*/
xlsx.write("C4", true, format2);
if(!xlsx.selectSheet("ziv")){/*在当前打开的xlsx文件中，找一个名字为ziv的sheet*/
xlsx.addSheet("ziv");//找不到的话就添加一个名为ziv的sheet
}
for (int i=10; i<20; ++i) {/*写入一串数字*/
xlsx.write(i, 1, i*i*i); //A10:A19
xlsx.write(i, 2, i*i); //B10:B19
xlsx.write(i, 3, i*i-1); //C10:C19
}
QXlsx::Chart *pieChart = xlsx.insertChart(3, 5, QSize(300, 300));/*在3行5列的位置插入一个图标*/
pieChart->setChartType(QXlsx::Chart::CT_Pie);/*插入一个饼形图*/
pieChart->addSeries(QXlsx::CellRange("A10:A19"));/*饼形图添加数据*/
pieChart->addSeries(QXlsx::CellRange("B10:B19"));
pieChart->addSeries(QXlsx::CellRange("C10:C19"));
QXlsx::Chart *barChart = xlsx.insertChart(3, 13, QSize(300, 300));/*在3行13列的位置插入一个图标*/
barChart->setChartType(QXlsx::Chart::CT_Bar);/*条形图*/
barChart->addSeries(QXlsx::CellRange("A10:C19"));/*给条形图加入数据*/
QImage image(40, 100, QImage::Format_RGB32);/*新建一个Qimage,大小40*100*/
image.fill(Qt::green);/*填充绿色*/
xlsx.insertImage(1, 1, image);/*插入图片*/
xlsx.saveAs("book1.xlsx");/*保存*/
QXlsx::Document xlsx2("Book1.xlsx");/*复制book1到book2*/
xlsx2.saveAs("Book2.xlsx");
return 0;
}
效果如下：
到此为止对于Qt Xlsx 的使用应该可以满足大部分的需求，如有疑问欢迎留言指正，原文地址:
