1.QT操作office的基本方式

通过QT操作Office软件,可以使用Qt的QAxObject类来进行操作。下面是一个例子,展示了通过Qt操作Excel的基本方式:

#include #include int main(int argc, char *argv[]) { QApplication app(argc, argv); QAxObject excel("Excel.Application"); excel.setProperty("Visible", true); QAxObject *workbooks = excel.querySubObject("Workbooks"); QAxObject *workbook = workbooks->querySubObject("Add"); QAxObject *sheets = workbook->querySubObject("Sheets"); QAxObject *sheet = sheets->querySubObject("Item(int)", 1); QAxObject *cell = sheet->querySubObject("Cells(int,int)", 1, 1); cell->setProperty("Value", "Hello, World!"); workbook->dynamicCall("SaveAs(const QString&)", "C:\\path\\to\\file.xlsx"); workbook->dynamicCall("Close(Boolean)", false); excel.dynamicCall("Quit()"); delete cell; delete sheet; delete sheets; delete workbook; delete workbooks; return app.exec(); }

上述示例中,首先创建了一个QAxObject实例,指定了要操作的Office软件,这里是Excel。然后通过querySubObject方法来获取各种对象,例如Workbooks、Sheets和Cells。使用这些对象,可以执行各种操作,如添加工作簿、添加工作表、获取单元格并设置值等。最后,使用dynamicCall方法执行一些动态调用,例如保存工作簿,并关闭Excel应用程序。

通过类似的方式,你可以使用Qt来操作其他Office软件,如Word和PowerPoint。只需将上述示例中的"Excel.Application"替换为"Word.Application"或"PowerPoint.Application"即可。

需要注意的是,要在Qt项目中使用Qt的ActiveX模块,需要在Qt项目文件(.pro)中添加如下行:

QT += axcontainer

希望这个例子能帮到你,祝你成功操作Office软件!

2.QT对Excel/office的基本读写

通过Qt可以实现对Office软件(如Excel、Word和PowerPoint)的基本读写操作。以下是一些示例代码,展示了如何使用Qt来读取和写入Excel、Word和PowerPoint文档的基本方法:

读取Excel文档:

#include #include int main(int argc, char *argv[]) { QApplication app(argc, argv); QAxObject excel("Excel.Application"); excel.setProperty("Visible", true); QAxObject *workbooks = excel.querySubObject("Workbooks"); QAxObject *workbook = workbooks->querySubObject("Open(const QString&)", "C:\\path\\to\\file.xlsx"); QAxObject *sheets = workbook->querySubObject("Sheets"); QAxObject *sheet = sheets->querySubObject("Item(int)", 1); QAxObject *cell = sheet->querySubObject("Cells(int,int)", 1, 1); QString value = cell->property("Value").toString(); qDebug() querySubObject("Open(const QString&)", "C:\\path\\to\\file.xlsx"); QAxObject *sheets = workbook->querySubObject("Sheets"); QAxObject *sheet = sheets->querySubObject("Item(int)", 1); QAxObject *cell = sheet->querySubObject("Cells(int,int)", 1, 1); cell->setProperty("Value", "Hello, World!"); workbook->dynamicCall("Save()"); workbook->dynamicCall("Close(Boolean)", false); excel.dynamicCall("Quit()"); delete cell; delete sheet; delete sheets; delete workbook; delete workbooks; return app.exec(); }

读取Word文档:

#include #include int main(int argc, char *argv[]) { QApplication app(argc, argv); QAxObject word("Word.Application"); word.setProperty("Visible", true); QAxObject *documents = word.querySubObject("Documents"); QAxObject *document = documents->querySubObject("Open(const QString&)", "C:\\path\\to\\file.docx"); QAxObject *selection = word.querySubObject("Selection"); QString text = selection->property("Text").toString(); qDebug() querySubObject("Add()"); QAxObject *selection = word.querySubObject("Selection"); selection->dynamicCall("TypeText(const QString&)", "Hello, World!"); document->dynamicCall("SaveAs(const QString&)", "C:\\path\\to\\file.docx"); document->dynamicCall("Close(Boolean)", false); word.dynamicCall("Quit()"); delete selection; delete document; delete documents; return app.exec(); }

读取PowerPoint文档:

#include #include int main(int argc, char *argv[]) { QApplication app(argc, argv); QAxObject powerpoint("PowerPoint.Application"); powerpoint.setProperty("Visible", true); QAxObject *presentations = powerpoint.querySubObject("Presentations"); QAxObject *presentation = presentations->querySubObject("Open(const QString&)", "C:\\path\\to\\file.pptx"); QAxObject *slides = presentation->querySubObject("Slides"); QAxObject *slide = slides->querySubObject("Item(int)", 1); QAxObject *shapes = slide->querySubObject("Shapes"); int shapeCount = shapes->property("Count").toInt(); qDebug() querySubObject("Add()"); QAxObject *slides = presentation->querySubObject("Slides"); QAxObject *slide = slides->querySubObject("Add(int, int)", 1, 1); QAxObject *shapes = slide->querySubObject("Shapes"); QAxObject *textShape = shapes->querySubObject("AddTextEffect(int, const QString&, const QString&, double, double, double, double)"); textShape->setProperty("Text", "Hello, World!"); presentation->dynamicCall("SaveAs(const QString&)", "C:\\path\\to\\file.pptx"); presentation->dynamicCall("Close(Boolean)", false); powerpoint.dynamicCall("Quit()"); delete textShape; delete shapes; delete slide; delete slides; delete presentation; delete presentations; return app.exec(); }

请确保在Qt项目文件(.pro)中添加了QT += axcontainer以支持Qt的ActiveX模块。

希望以上示例能帮到你,祝你成功操作Office软件!

3.QT操作word应用

通过Qt可以使用ActiveX技术来操作Word应用。以下是一个示例代码,展示了如何使用Qt来打开Word应用、创建文档、写入内容和保存文档的基本方法:

#include #include int main(int argc, char *argv[]) { QApplication app(argc, argv); QAxObject word("Word.Application"); word.setProperty("Visible", true); QAxObject *documents = word.querySubObject("Documents"); QAxObject *document = documents->querySubObject("Add()"); QAxObject *selection = word.querySubObject("Selection"); selection->dynamicCall("TypeText(const QString&)", "Hello, World!"); document->dynamicCall("SaveAs(const QString&)", "C:\\path\\to\\file.docx"); document->dynamicCall("Close(Boolean)", false); word.dynamicCall("Quit()"); delete selection; delete document; delete documents; return app.exec(); }

在该示例中,我们首先创建了一个QAxObject实例,用于表示Word应用。然后,我们设置了Visible属性为true,这样可以在打开的Word界面中看到操作过程。接下来,我们使用querySubObject方法获取了Documents对象,并通过Add方法创建了一个新的文档对象。然后,我们使用querySubObject方法获取了Selection对象,然后使用TypeText方法向文档中输入了"Hello, World!"的内容。最后,我们使用SaveAs方法将文档保存到指定路径,然后使用Close方法关闭文档。最后,我们调用Quit方法关闭Word应用。

请确保在Qt项目文件(.pro)中添加了QT += axcontainer以支持Qt的ActiveX模块。

希望以上示例能帮到你,祝你操作Word应用成功!
