涉及到开发桌面程序,尤其是文本处理,剪贴板就很常用,不像 java 中那么烦锁,wxpython 中访问剪贴板非常简单,寥寥几句足以。
# 取得剪贴板并确保其为打开状态 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()
写值:
text_obj.SetText(‘要写入的值') wx.TheClipboard.SetData(text_obj)
下面的例子中,点击 Copy 会将文本框中的值复制到剪贴板,点击 Paste 会将剪贴板中的文本粘贴到文本框中。
""" Get text from and put text on the clipboard. """ import wx class 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()
