entryscrollpanel.py

import wx titlepanel import titlepanel  class entryscrollpanel(wx.scrolledwindow):     def __init__(self, parent, id, pos, size, style):         #self.setscrollrate( 5, 5 )          self.entrypgbox = wx.boxsizer(wx.vertical)          #self.enttitle = titlepanel(self, -1) i've tried no success         self.enttitle = titlepanel(wx.panel, -1)          self.entrypgbox.addspacer(10)         self.entrypgbox.add(self.enttitle, 0, wx.expand)         self.entrypgbox.addspacer(10)          self.setautolayout(true)         self.setsizer(self.entrypgbox)         self.entrypgbox.fit(self) 

titlepanel.py

import wx  class titlepanel(wx.panel):     def __init__(self, parent, id):         wx.panel.__init__(self, parent, id)         titlesizer = wx.boxsizer(wx.horizontal)          titlelbl = wx.statictext(self, label="title: ")         titletxt = wx.textctrl(self, size=(140,-1))         datelbl = wx.statictext(self, label="date: ")         datecal = wx.datepickerctrl(self, wx.dp_dropdown)          titlesizer.add(titlelbl,0,wx.expand)         titlesizer.add(titletxt,1,wx.expand)         titlesizer.add(datelbl,0,wx.expand)         titlesizer.add(datecal,0,wx.expand) 

this error get:

how add self.enttitle entryscrollpanel?

thank , help!

a panel not wxwindow that:

self.enttitle = titlepanel(wx.panel, -1) 

doesn't work , produces traceback.
above code instantiating wx.panel subclass (titlepanel) , sending wx.panel parent constructor in:

class titlepanel(wx.panel):     def __init__(self, parent, id):         wx.panel.__init__(self, parent, id) 

but panel needs window (p.e. frame) parent.

thus must instead:

self.enttitle = titlepanel(self, -1) 

as self, here, parent of titlepanel, wx.scrolledwindow

also note did not initialized scrolledwindow:

class entryscrollpanel(wx.scrolledwindow):     def __init__(self, parent, id):         wx.scrolledwindow.__init__(self, parent, id)    <--- addd
