Qt 源码之 Qt 操作 Excel是本文丫介绍的内容,先来看内容:QAxWidget excel("Excel.Application");
1、显示当前窗口:
excel.setProperty("Visible", true);
2、更改 Excel 标题栏:
excel.setProperty("Caption", "Invoke Microsoft Excel");
3、添加新工作簿:
QAxObject * workbooks = excel.querySubObject("WorkBooks");
workbooks->dynamicCall("Add");
4、打开已存在的工作簿:
workbooks->dynamicCall("Open (const QString&)", QString("c:/test.xls"));
5、获取活动工作簿:
QAxObject * workbook = excel.querySubObject("ActiveWorkBook");
6、获取所有的工作表:
QAxObject * worksheets = workbook->querySubObject("WorkSheets");
7、获取工作表数量:
int intCount = worksheets->property("Count").toInt();
8、获取***个工作表:
QAxObject * worksheet = workbook->querySubObject("Worksheets(int)", 1);
9、获取cell的值:
QAxObject * range = worksheet->querySubObject("Cells(int,int)", 1, 1 );
示例代码:
- view plaincopy to clipboardprint?
- #include <QtGui>
- #include <QAxObject>
- #include <QAxWidget>
- #include <qaxselect.h>
- int main(int argc, char **argv)
- {
- QApplication a(argc, argv);
- QAxSelect select;
- select.show();
- QAxWidget excel("Excel.Application");
- excel.setProperty("Visible", true);
- QAxObject * workbooks = excel.querySubObject("WorkBooks");
- workbooks->dynamicCall("Open (const QString&)", QString("c:/test.xls"));
- QAxObject * workbook = excel.querySubObject("ActiveWorkBook");
- QAxObject * worksheets = workbook->querySubObject("WorkSheets");
- int intCount = worksheets->property("Count").toInt();
- for (int i = 1; i <= intCount; i++)
- {
- int intVal;
- QAxObject * worksheet = workbook->querySubObject("Worksheets(int)", i);
- qDebug() << i << worksheet->property("Name").toString();
- QAxObject * range = worksheet->querySubObject("Cells(1,1)");
- intVal = range->property("Value").toInt();
- range->setProperty("Value", QVariant(intVal+1));
- QAxObject * range2 = worksheet->querySubObject("Range(C1)");
- intVal = range2->property("Value").toInt();
- range2->setProperty("Value", QVariant(intVal+1));
- }
- QAxObject * worksheet = workbook->querySubObject("Worksheets(int)", 1);
- QAxObject * usedrange = worksheet->querySubObject("UsedRange");
- QAxObject * rows = usedrange->querySubObject("Rows");
- QAxObject * columns = usedrange->querySubObject("Columns");
- int intRowStart = usedrange->property("Row").toInt();
- int intColStart = usedrange->property("Column").toInt();
- int intCols = columns->property("Count").toInt();
- int intRows = rows->property("Count").toInt();
- for (int i = intRowStart; i < intRowStart + intRows; i++)
- {
- for (int j = intColStart; j <= intColStart + intCols; j++)
- {
- QAxObject * range = worksheet->querySubObject("Cells(int,int)", i, j );
- qDebug() << i << j << range->property("Value");
- }
- }
- excel.setProperty("DisplayAlerts", 0);
- workbook->dynamicCall("SaveAs (const QString&)", QString("c:/xlsbyqt.xls"));
- excel.setProperty("DisplayAlerts", 1);
- workbook->dynamicCall("Close (Boolean)", false);
- excel.dynamicCall("Quit (void)");
- return a.exec();
- }
