在Linux系统下,可以使用Qt5.9.5的QAxObject类来读取.xls文件。需要先在.pro文件中添加win32 LIBS的配置,以便在Linux系统下使用QAxObject。
首先,需要在代码中包含相关的头文件和命名空间:
```cpp
#include <QAxObject>
using namespace Qt;
```
然后,可以使用以下代码来读取.xls文件:
```cpp
QString filePath = "your_file_path.xls"; // 替换成你的.xls文件路径
QAxObject* excel = new QAxObject("Excel.Application");
QAxObject* workbooks = excel->querySubObject("Workbooks");
QAxObject* workbook = workbooks->querySubObject("Open(const QString &)", filePath);
QAxObject* worksheets = workbook->querySubObject("Worksheets");
QAxObject* worksheet = worksheets->querySubObject("Item(int)", 1);
QAxObject* usedRange = worksheet->querySubObject("UsedRange");
QAxObject* rows = usedRange->querySubObject("Rows");
QAxObject* columns = usedRange->querySubObject("Columns");
int rowCount = rows->property("Count").toInt();
int columnCount = columns->property("Count").toInt();
for (int row = 1; row <= rowCount; ++row) {
for (int column = 1; column <= columnCount; ++column) {
QAxObject* cell = worksheet->querySubObject("Cells(int, int)", row, column);
QString cellValue = cell->property("Value").toString();
// 处理单元格的数据
// ...
delete cell;
}
}
delete columns;
delete rows;
delete usedRange;
delete worksheet;
delete worksheets;
workbook->dynamicCall("Close()");
delete workbook;
delete workbooks;
excel->dynamicCall("Quit()");
delete excel;
```
注意,在读取完数据后,需要释放相关的QAxObject对象,以避免内存泄漏。另外,需要取消对Excel应用程序的引用,以确保Excel进程被正确关闭。
以上是在Linux系统下使用Qt5.9.5读取.xls文件的方法。请注意,QAxObject类在Linux系统中可能有一些限制和兼容性问题,建议在使用之前查看相关文档和资料,并进行充分的测试和验证。
