涉及到开发桌面程序,尤其是文本处理,剪贴板就很常用,不像 java 中那么烦锁,wxpython 中访问剪贴板非常简单,寥寥几句足以。

# 取得剪贴板并确保其为打开状态 text_obj = wx.TextDataObject() wx.TheClipboard. Open () if wx.TheClipboard.IsOpened() or wx.TheClipboard. Open (): # do something... wx.TheClipboard.Close() |
取值:
1
2
|
if wx.TheClipboard.GetData(text_obj): text = text_obj.GetText() |
写值:
1
2
|
text_obj.SetText(‘要写入的值') wx.TheClipboard.SetData(text_obj) |
下面的例子中,点击 Copy 会将文本框中的值复制到剪贴板,点击 Paste 会将剪贴板中的文本粘贴到文本框中。
