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()
