Question

我正在尝试做一个非常简单的GUI，当将文件拖放到应用程序上时可以更新文本标签。

到目前为止，我已经能够识别出何时删除了文件并在控制台上打印了一条消息。不幸的是，当文件被删除时，我一直试图将标签（带有消息“ Linkin Park”）更新为“ Three Day Grace”，但我还没有做到。

有人可以帮我解决mi问题吗？

您只需要引用Sub PlatingSheet() Const FPATH As String = "\\in-mmge-file\users\tbever\Desktop\VBA\Plating Sheets\" Dim wbTarget As Workbook, wbSource As Workbook Set wbSource = Workbooks.Open(FPATH & "Copy - 24605_17 QC Results and Notes.xlsx") Set wbTarget = Workbooks.Open(FPATH & "Copy - 1.1Unified_Plating_Template.xlsx") With wbSource.Sheets(1).Range("B5:B96") 'assign the value directly wbTarget.Sheets(1).Range("G4").Resize(.Rows.Count, .Columns.Count).Value = .Value End With End Sub，以便您可以访问MainLayout。如果您将artistName调整为：

我认为它将起作用。

Kivy，Python：更新标签on_file_drop
