使用 UNO 在同一窗口中打开多个文档

【中文标题】使用 UNO 在同一窗口中打开多个文档

【英文标题】：Opening multiple documents in a same window with UNO

【发布时间】：2010-07-28 10:01:53

【问题描述】：

我在 python 中有一个脚本，它使用 pyuno 从许多 excel 文件中提取数据。

我的问题是，对于每个文件，我用

打开和关闭一个窗口

url = unohelper.systemPathToFileUrl(os.path.abspath(file_name))
file = desktop.loadComponentFromURL(url, "_blank", 0, () )

和

file.close(True)

有没有什么方法可以在不打开窗口的情况下从文件中提取数据？或者至少不用为每个文件打开一个新窗口？

【参考方案1】：

这会打开一个文档而不显示：

// Call the bootstrap to get the Component context
com.sun.star.uno.XComponentContext oComponentContext = null;
try

    String oooExeFolder = "C:/Program Files/OpenOffice.org 3/program/";
    oComponentContext = BootstrapSocketConnector.bootstrap(oooExeFolder);

catch(com.sun.star.comp.helper.BootstrapException ex)

    System.out.println(ex.getMessage());


if(oComponentContext != null)
