wxPython使用系统剪切板的方法

程序运行效果如下图所示：

主要代码如下：

import wx
########################################################################
class ClipboardPanel(wx.Panel):
 """"""
 #----------------------------------------------------------------------
 def __init__(self, parent):
 """Constructor"""
 wx.Panel.__init__(self, parent)
 lbl = wx.StaticText(self, label="Enter text to copy to clipboard:")
 self.text = wx.TextCtrl(self, style=wx.TE_MULTILINE)
 copyBtn = wx.Button(self, label="Copy")
 copyBtn.Bind(wx.EVT_BUTTON, self.onCopy)
 copyFlushBtn = wx.Button(self, label="Copy and Flush")
 copyFlushBtn.Bind(wx.EVT_BUTTON, self.onCopyAndFlush)
 sizer = wx.BoxSizer(wx.VERTICAL)
 sizer.Add(lbl, 0, wx.ALL, 5)
 sizer.Add(self.text, 1, wx.EXPAND)
 sizer.Add(copyBtn, 0, wx.ALL|wx.CENTER, 5)
 sizer.Add(copyFlushBtn, 0, wx.ALL|wx.CENTER, 5)
 self.SetSizer(sizer)
 #----------------------------------------------------------------------
 def onCopy(self, event):
 """"""
 self.dataObj = wx.TextDataObject()
 self.dataObj.SetText(self.text.GetValue())
 if wx.TheClipboard.Open():
 wx.TheClipboard.SetData(self.dataObj)
 wx.TheClipboard.Close()
 else:
 wx.MessageBox("Unable to open the clipboard", "Error")
 #----------------------------------------------------------------------
 def onCopyAndFlush(self, event):
 """"""
 self.dataObj = wx.TextDataObject()
 self.dataObj.SetText(self.text.GetValue())
 if wx.TheClipboard.Open():
 wx.TheClipboard.SetData(self.dataObj)
 wx.TheClipboard.Flush()
 else:
 wx.MessageBox("Unable to open the clipboard", "Error")
 self.GetParent().Close()
########################################################################
class ClipboardFrame(wx.Frame):
 """"""
 #----------------------------------------------------------------------
 def __init__(self):
 """Constructor"""
 wx.Frame.__init__(self, None, title="Clipboard Tutorial")
 panel = ClipboardPanel(self)
 self.Show()
if __name__ == "__main__":
 app = wx.App(False)
 frame = ClipboardFrame()
 app.MainLoop()

希望本文所述对大家的Python程序设计有所帮助。
