涉及到開發傳統型程式,尤其是文本處理,剪貼簿就很常用,不像 java 中那麼煩鎖,wxpython 中訪問剪貼簿非常簡單,寥寥幾句足以。
# 取得剪貼簿並確保其為開啟狀態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()
寫值:
text_obj.SetText(‘要寫入的值')wx.TheClipboard.SetData(text_obj)
下面的例子中,點擊 Copy 會將文字框中的值複製到剪貼簿,點擊 Paste 會將剪貼簿中的文本粘貼到文字框中。
"""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()
