这更像是一个uno问题,而不是一个python问题。下面的代码对3个单元格进行了简单的更新。在工作表上配置的3个按钮调用dowriteonce()dowritetwice()和dowritethrice(),它们都会更新和工作,就像您可能希望将数字和文本写入选定的单元格一样。
问题出现的地方是,当用户在UI中编辑单元格时,将阻止通过执行该功能对该单元格的任何后续更新。因此,只需在calc UI中单击单元格C4,就可以防止writethrice()函数更新单元格C4。如果我删除内容并单击UI中的另一个单元格,例如C5,那么一切都会正常工作,单击按钮时C4会更新。
我想要做的是在执行之前将UI编辑光标重新定位到未使用的单元格,以防止这种情况发生。用户复制粘贴会将活动光标留在不可预测的位置,如果我无法隔离光标,则会进行计算。
所以问题是,如何通过UNO API将UI编辑光标移动到命名单元格?或者如果它更容易,只需暂时停用它。

class ODSCursor(unohelper.Base):
# predeclare class properties

# initialize uno handle only once and get the first sheet

cls.ctx = uno.getComponentContext()
cls.desktop = cls.ctx.ServiceManager.createInstanceWithContext("com.sun.star.frame.Desktop", cls.ctx)
cls.model = cls.desktop.getCurrentComponent()
# cls.activesheet = cls.model.Sheets.getByName("Sheet1")
cls.activesheet = cls.model.Sheets.getByIndex(0)
return (cls.activesheet)

答案 0 :(得分:1)
在以下代码中,在更改值之前取消选择单元格,然后再次选择。这样,即使用户处于编辑模式,也可以修改单元格。
似乎对Python类方法和变量存在一些混淆,所以我也改变了这些部分。
