本文实例为大家分享了基于wxPython的GUI实现输入对话框的具体代码，供大家参考，具体内容如下

编程时,免不了要输入一些参数等,这时输入对话框就派上用处了:

import wx
 
class TextEntryDialog(wx.Dialog):
 
 def __init__(self, parent=None, title='Title', caption='Caption',size=(500, 200)):
  '''
  #~ dialog = TextEntryDialog(parent=None, title=title,caption=caption,size=size)
  #~ dialog = TextEntryDialog()
  ''' 
  style = wx.DEFAULT_DIALOG_STYLE | wx.RESIZE_BORDER
  super(TextEntryDialog, self).__init__(parent, -1, title=title, style=style)
  self.text = wx.StaticText(self, -1, caption)
  self.input = wx.TextCtrl(self, -1, style=wx.TE_MULTILINE)
  self.input.SetInitialSize(size)
  self.buttons = self.CreateButtonSizer(wx.OK|wx.CANCEL)
  self.sizer = wx.BoxSizer(wx.VERTICAL)
  self.sizer.Add(self.text, 0, wx.ALL, 5)
  self.sizer.Add(self.input, 1, wx.EXPAND|wx.ALL, 5)
  self.sizer.Add(self.buttons, 0, wx.EXPAND|wx.ALL, 5)
  self.SetSizerAndFit(self.sizer)
  self.Center()
 def SetValue(self, value):
  self.input.SetValue(value)
 def GetValue(self):
  return self.input.GetValue()
 
def wxinputbox(Initialstring='Initial String',title='Title',caption='Caption',size=(500,200)):
 '''
 #~ >>>stringvalue=wxinputbox(Initialstring='Initial String',title='Title',caption='Caption',size=(500,200)):
 #~ >>> stringvalue=wxinputbox()
 '''
 app = wx.PySimpleApp()
 #~ dialog = TextEntryDialog(None, title=title,caption=caption,size=size)
 dialog = TextEntryDialog()
 dialog.SetValue(Initialstring)
 if dialog.ShowModal() == wx.ID_OK:
  stringvalue= dialog.GetValue()
 else:
  stringvalue=''
  dialog.Destroy()
  app.MainLoop()
 return stringvalue
  
if __name__ == '__main__': 
 #~ #使用wx的输入对话框
 stringvalue=wxinputbox()
 print(stringvalue)
 
 
#~ if __name__ == '__main__':
 #~ app = wx.PySimpleApp()
 #~ #使用wx自带的输入对话框
 #~ dialog = wx.TextEntryDialog(None, 'Rules:', 'Edit rules',
 #~ style=wx.TE_MULTILINE|wx.OK|wx.CANCEL)
 #~ dialog.SetInitialSize((500,200))
 #~ if dialog.ShowModal() == wx.ID_OK:
  #~ print 'OK'
 #~ dialog.Destroy()
 #~ app.MainLoop()

效果如下:
