This article mainly introduces how to use wxPython to obtain data from the system clipboard. wxPython is a very popular Python graphics library. If you need it, refer to the development of desktop programs, in particular, for 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.
