How to Use wxPython to obtain data in the system clipboard: wxpython clipboard

When it comes to developing desktop programs, especially text processing, clipboard is very common. Unlike java, the access to the clipboard in wxpython is very simple and a few words are enough.

# Obtain the clipboard and make sure it is in the open status text_obj = wx. textDataObject () wx. theClipboard. open () if wx. theClipboard. isOpened () or wx. theClipboard. open (): # do something... wx. theClipboard. close ()

Valid value:

if wx.TheClipboard.GetData(text_obj):  text = text_obj.GetText()

Write value:

Text_obj.SetText ('value to be written ') wx. TheClipboard. SetData (text_obj)

In the following example, click Copy to Copy the value in the text box to the clipboard. Click Paste to Paste the text in the clipboard to the text box.

"""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()
