    <p>Hi all I am learning Python and making a GUI model using wxPython.</p> <p>I want to connect vai SSH, I am used pexpect for this purpose. I want to display a msg box saying, "Connected to server" or if disconnected, "connection not established" I am cannot figure out how to do this and the GUI freezes when it connects. How do I avoid freezing the GUI? My sample code is:</p> <pre><code>import time import sys import pexpect c = pexpect.spawn("ssh -Y -L xxxx:localhost:xxxx user @ host.com") #time.sleep(0.1) c.expect("[pP]aasword") c.sendline("xxxxxx") #time.sleep(0.2) c.interact() c.pexpect([user@host.com~]$) </code></pre> <p>After its connects to SSH here, the GUI freezes. After connecting, I want show the connection status in a message box, not in terminal. Please suggest how to do it; as a beginner I find it difficult.</p> <p>Thanks in advance. </p> <h1>Update:</h1> <pre><code>import wx import os import pexpect import sys import subprocess import time class Connect_ssh(wx.Frame): def __init__ (self, *args, **kw): wx.Frame.__init__(self,None,wx.ID_ANY,"Secure Shell", size=(310,200),style=wx.DEFAULT_FRAME_STYLE ^ wx.MAXIMIZE_BOX ^ wx.RESIZE_BORDER) panel = wx.Panel(self) txt1 = wx.StaticText(panel, label="Account name:",pos=(20, 55)) txt2 = wx.StaticText(panel, label="Password",pos=(20, 105)) self.txt_name = wx.TextCtrl(panel, -1, size=(130, -1), pos=(160,50)) self.txt_pswd= wx.TextCtrl(panel, -1, size=(130, -1),pos= (160,100),style=wx.TE_PASSWORD) button1 = wx.Button(panel, -1, "Connect",size=(-1,-1), pos=(50, 160)) button2 = wx.Button(panel, -1, "Disconnect",size=(-1,-1), pos=(170, 160)) self.Bind(wx.EVT_BUTTON,self.OnConc,button1) def OnConc(self,event): u_name = self.txt_name.GetValue() passwd = self.txt_pswd.GetValue() child = pexpect.spawn("ssh -Y -L xxx:localhost:xxx %s@host.com" % (str(u_name))) child.expect("%s@host.com's password:" % (str(u_name)) ) child.sendline("%s" % (str(passwd))) child.interact() #child.sendline("%s" % str(sub)) child.expect("[%s@qvislabs.com~]$"% (str(u_name)) ) #time.sleep() #self.Destroy() msg = wx.MessageBOx(" '%s'@host.com is connected" % (str(u_name)), "Info",wx_OK) self.Hide() if __name__=="__main__": app = wx.App() Connect_ssh().Show() app.MainLoop() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
