WxPython [TextCtrl]：使用TextCtrl函數將光標定位到文本結尾的方式。

Question

很高興認識你。我有一個關於使用wxpython的問題。這是我無法控制TextCtrl函數的光標。這是我的wxpython代碼。

#!/usr/bin/python 
import wx 

def get_main_screen_text(): 
    text = "\n  [Anyfusion Monitoring System]\n\n" 
    return text 

class Tom(wx.Dialog): 
    def __init__(self, parent, id, title): 
     wx.Dialog.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(400, 420)) 
     panel = wx.Panel(self, -1) 
     vbox = wx.BoxSizer(wx.HORIZONTAL) 
     vbox1 = wx.BoxSizer(wx.VERTICAL) 
     vbox2 = wx.BoxSizer(wx.VERTICAL)  
     self.message = get_main_screen_text() 

     self.write = wx.TextCtrl(panel, -1, style=wx.TE_MULTILINE, value=self.message) 
     System_Checkup = wx.Button(panel, 1, label='System_Checkup') 
     Open_the_Web = wx.Button(panel, 1, label=' Open_the_Web ') 
     Help_Desk = wx.Button(panel, 1, label=' Help_Desk ') 
     Exit = wx.Button(panel, 1, label=' Exit ') 

     vbox1.Add(self.write, 1, wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT | wx.BOTTOM, 15) 
     vbox2.Add(System_Checkup, 0, wx.TOP | wx.TOP | wx.RIGHT, 15) 
     vbox2.Add(Open_the_Web, 0, wx.TOP | wx.RIGHT, 15) 
     vbox2.Add(Help_Desk, 0, wx.TOP, 230) 
     vbox2.Add(Exit, 0, wx.TOP | wx.RIGHT, 15)   
     vbox.Add(vbox1, 1, wx.EXPAND) 
     vbox.Add(vbox2, 0, wx.TOP) 
     self.Bind(wx.EVT_BUTTON, self.EventHandler, id=1) 
     panel.SetSizer(vbox) 
     self.Centre() 

    def EventHandler(self, event): 
     b=event.GetEventObject().GetLabel() 
     if b.endswith('System_Checkup'): 
      self.message = self.message+"\nABC" 
      self.write.SetValue(self.message) 
      self.write.SetEditable(False) 
      self.write.SetScrollPos(wx.VERTICAL,0) 
      self.write.SetInsertionPoint(0) 
      self.write.Refresh()    

class MyApp(wx.App): 
    def OnInit(self): 
     frame = Tom(None, -1, 'Tom') 
     frame.ShowModal() 
     frame.Destroy() 
     return True 

if __name__ == "__main__": 
    app = MyApp() 
    app.MainLoop() 

我想將光標定位到文本的末尾。但是我的程序沒有工作。下面捕獲我的wxpython程序。

下一頁捕捉的wxPython程序的預期結果。

非常感謝你。我想盡快..謝謝解決這個問題..

使用SetInsertionPointEnd

#!/usr/bin/python 
import wx 

def get_main_screen_text(): 
    text = "\n  [Anyfusion Monitoring System]\n\n" 
    return text 

class Tom(wx.Dialog): 
    def __init__(self, parent, id, title): 
     wx.Dialog.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(400, 420)) 
     panel = wx.Panel(self, -1) 
     vbox = wx.BoxSizer(wx.HORIZONTAL) 
     vbox1 = wx.BoxSizer(wx.VERTICAL) 
     vbox2 = wx.BoxSizer(wx.VERTICAL)  
     self.message = get_main_screen_text() 

     self.write = wx.TextCtrl(panel, -1, style=wx.TE_MULTILINE, value=self.message) 
     System_Checkup = wx.Button(panel, 1, label='System_Checkup') 
     Open_the_Web = wx.Button(panel, 1, label=' Open_the_Web ') 
     Help_Desk = wx.Button(panel, 1, label=' Help_Desk ') 
     Exit = wx.Button(panel, 1, label=' Exit ') 

     vbox1.Add(self.write, 1, wx.EXPAND | wx.TOP | wx.RIGHT | wx.LEFT | wx.BOTTOM, 15) 
     vbox2.Add(System_Checkup, 0, wx.TOP | wx.TOP | wx.RIGHT, 15) 
     vbox2.Add(Open_the_Web, 0, wx.TOP | wx.RIGHT, 15) 
     vbox2.Add(Help_Desk, 0, wx.TOP, 230) 
     vbox2.Add(Exit, 0, wx.TOP | wx.RIGHT, 15)   
     vbox.Add(vbox1, 1, wx.EXPAND) 
     vbox.Add(vbox2, 0, wx.TOP) 
     self.Bind(wx.EVT_BUTTON, self.EventHandler, id=1) 
     panel.SetSizer(vbox) 
     self.Centre() 

    def EventHandler(self, event): 
     b=event.GetEventObject().GetLabel() 
     if b.endswith('System_Checkup'): 
      self.message = self.message+"\nABC" 
      self.write.SetValue(self.message) 
      self.write.SetEditable(False) 
      self.write.SetScrollPos(wx.VERTICAL,0) 
      self.write.SetFocus() 
      self.write.SetInsertionPointEnd() 
      self.write.Refresh()    

class MyApp(wx.App): 
    def OnInit(self): 
     frame = Tom(None, -1, 'Tom') 
     frame.ShowModal() 
     frame.Destroy() 
     return True 

if __name__ == "__main__": 
    app = MyApp() 
    app.MainLoop()
