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/' target='_blank'>python 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。

"""Get text from and put text on the clipboard."""import wxclass MyFrame(wx.Frame):  def __init__(self):    wx.Frame.__init__(self, None, title='Accessing the clipboard', size=(400, 300))    # Components    self.panel = wx.Panel(self)    self.text = wx.TextCtrl(self.panel, pos=(10, 10), size=(370, 220))    self.copy = wx.Button(self.panel, wx.ID_ANY, label='Copy', pos=(10, 240))    self.paste = wx.Button(self.panel, wx.ID_ANY, label='Paste', pos=(100, 240))    # Event bindings.    self.Bind(wx.EVT_BUTTON, self.OnCopy, self.copy)    self.Bind(wx.EVT_BUTTON, self.OnPaste, self.paste)  def OnCopy(self, event):    text_obj = wx.TextDataObject()    text_obj.SetText(self.text.GetValue())    if wx.TheClipboard.IsOpened() or wx.TheClipboard.Open():      wx.TheClipboard.SetData(text_obj)      wx.TheClipboard.Close()  def OnPaste(self, event):    text_obj = wx.TextDataObject()    if wx.TheClipboard.IsOpened() or wx.TheClipboard.Open():      if wx.TheClipboard.GetData(text_obj):        self.text.SetValue(text_obj.GetText())      wx.TheClipboard.Close()app = wx.App(False)frame = MyFrame()frame.Show(True)app.MainLoop()
