使用wxPython获取系统剪贴板中的数据的教程
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：
if wx.TheClipboard.GetData(text_obj): text = text_obj.GetText()
写值：
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。

frame = MyFrame()
frame.Show(True)
app.MainLoop()
