python - TextCtrl widget crashing in linux -

i using below code snippet, working correctly in windows operating system, when comes linux, closing segmentation fault.

self.textmessage = wx.textctrl(self, -1, '', style=wx.te_multiline|wx.te_readonly) self.hsizer2.add(item=self.textmessage, proportion=1, flag=wx.expand|wx.all, border=3) self.vsizer.add(item=self.hsizer2, proportion=1, flag=wx.expand|wx.all, border=0) self.textmessage.appendtext(message+" \n") 

i using redhat enterprise linux. possible replace textctrl widget other widgets , there custom widgets textctrl?

also let me know if miss in above code avoid crash problem

thanks in advance.

i tested code in actual runnable example on kubuntu 14.04 box wxpython 2.8.12 , python 2.7.6 , worked fine. see following example:

import wx  ######################################################################## class mypanel(wx.panel):     """"""      #----------------------------------------------------------------------     def __init__(self, parent):         """constructor"""         wx.panel.__init__(self, parent)          self.vsizer = wx.boxsizer(wx.vertical)         self.hsizer2 = wx.boxsizer(wx.horizontal)          message = "the bright red fox"         self.textmessage = wx.textctrl(self, -1, '', style=wx.te_multiline|wx.te_readonly)         self.hsizer2.add(item=self.textmessage, proportion=1, flag=wx.expand|wx.all, border=3)         self.vsizer.add(item=self.hsizer2, proportion=1, flag=wx.expand|wx.all, border=0)         self.textmessage.appendtext(message+" \n")          self.setsizer(self.vsizer)  ######################################################################## class myframe(wx.frame):     """"""      #----------------------------------------------------------------------     def __init__(self):         """constructor"""         wx.frame.__init__(self, none, title="test")         panel = mypanel(self)          self.show()  if __name__ == "__main__":     app = wx.app(false)     frame = myframe()     app.mainloop()
