Paski przewijania nie pojawiają się w rozwijanym folderze FoldPanelBar w wxPython

Question

Po rozwinięciu paneli zwijanych wychodzi poza ramkę i paski przewijania nie są wyświetlane. Próbowałem użyć ScrolledPanel, ale nie pomogłem. Masz pojęcie, czego tu brakuje?

import wx 
from wx.lib import scrolledpanel 
import wx.lib.agw.foldpanelbar as fpb 
import wx.lib.scrolledpanel as sp 

class MyPanel(sp.ScrolledPanel): 

    def __init__(self, parent): 
     sp.ScrolledPanel.__init__(self, parent=parent, size=parent.GetSize(), style = wx.ALL|wx.EXPAND) 
     #self.SetAutoLayout(1) 
     self.SetupScrolling() 
     ##self.boxSizer = wx.BoxSizer(wx.VERTICAL)### 
     csStyle = fpb.CaptionBarStyle() 
     csStyle.SetFirstColour(wx.Colour(190, 190, 190, 255)) 
     csStyle.SetSecondColour(wx.Colour(167, 232, 146, 255)) 
     csStyle.SetCaptionFont(wx.Font(9, wx.DEFAULT, wx.NORMAL, wx.BOLD)) 

     m_pnl = fpb.FoldPanelBar(self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, 
          fpb.FPB_VERTICAL) 

     item = m_pnl.AddFoldPanel("Set 1", collapsed=True, cbstyle=csStyle) 

     self.listContainer = wx.ListCtrl(item, style=wx.LC_REPORT) 
     self.listContainer.InsertColumn(0, 'Column1', width=250) 
     self.listContainer.InsertColumn(1, 'Column2', width=150) 
     self.listContainer.InsertColumn(2, 'Column3') 

     m_pnl.AddFoldPanelWindow(item, self.listContainer) 
     btnAutoFix = wx.Button(item, wx.ID_ANY, "Go", size=(50,-1)) 
     m_pnl.AddFoldPanelWindow(item, btnAutoFix) 
     ###self.boxSizer.Add(m_pnl)## 


     item = m_pnl.AddFoldPanel("Set 2", collapsed=True, cbstyle=csStyle) 
     self.listContainer2 = wx.ListCtrl(item, style=wx.LC_REPORT) 
     self.listContainer2.InsertColumn(0, 'Column1', width=250) 
     self.listContainer2.InsertColumn(1, 'Column2', width=150) 
     self.listContainer2.InsertColumn(2, 'Column3') 

     m_pnl.AddFoldPanelWindow(item, self.listContainer2) 

     self.pnl = m_pnl 
     ##self.SetSizer(self.boxSizer)### 

if __name__ == '__main__': 
    app = wx.App(False) 
    frame = wx.Frame(None, size=(650, 400), style=wx.DEFAULT_FRAME_STYLE) 
    panel = MyPanel(frame) 
    # Add sizer information for the scrolled panel 
    szmain = wx.BoxSizer(wx.VERTICAL) 
    szmain.Add(panel.pnl, 1, wx.EXPAND|wx.ALL, 4) 
    panel.SetSizer(szmain) 
    frame.Show() 
    app.MainLoop()

Nie używaj domyślnego rozmiaru FoldPanelBar. Z jakiegoś powodu wydaje się, że widget zachowuje się głupio. Jeśli określisz rozmiar, paski przewijania będą wyświetlane poprawnie.

import wx 
import wx.lib.agw.foldpanelbar as fpb 
import wx.lib.scrolledpanel as scrolled 

class MyPanel(scrolled.ScrolledPanel): 

    def __init__(self, parent): 
     scrolled.ScrolledPanel.__init__(self, parent=parent, 
             size=parent.GetSize(), 
             style = wx.ALL|wx.EXPAND) 
     #self.SetAutoLayout(1) 
     self.SetupScrolling() 
     self.boxSizer = wx.BoxSizer(wx.VERTICAL) 
     csStyle = fpb.CaptionBarStyle() 
     csStyle.SetFirstColour(wx.Colour(190, 190, 190, 255)) 
     csStyle.SetSecondColour(wx.Colour(167, 232, 146, 255)) 
     csStyle.SetCaptionFont(wx.Font(9, wx.DEFAULT, wx.NORMAL, wx.BOLD)) 

     m_pnl = fpb.FoldPanelBar(self, wx.ID_ANY, wx.DefaultPosition, (600,800), 
          fpb.FPB_VERTICAL) 

     item = m_pnl.AddFoldPanel("Set 1", collapsed=True, cbstyle=csStyle) 

     self.listContainer = wx.ListCtrl(item, style=wx.LC_REPORT) 
     self.listContainer.InsertColumn(0, 'Column1', width=250) 
     self.listContainer.InsertColumn(1, 'Column2', width=150) 
     self.listContainer.InsertColumn(2, 'Column3') 

     m_pnl.AddFoldPanelWindow(item, self.listContainer) 
     btnAutoFix = wx.Button(item, wx.ID_ANY, "Go", size=(50,-1)) 
     m_pnl.AddFoldPanelWindow(item, btnAutoFix) 
     self.boxSizer.Add(m_pnl) 


     item = m_pnl.AddFoldPanel("Set 2", collapsed=True, cbstyle=csStyle) 
     self.listContainer2 = wx.ListCtrl(item, style=wx.LC_REPORT) 
     self.listContainer2.InsertColumn(0, 'Column1', width=250) 
     self.listContainer2.InsertColumn(1, 'Column2', width=150) 
     self.listContainer2.InsertColumn(2, 'Column3') 

     m_pnl.AddFoldPanelWindow(item, self.listContainer2) 

     self.pnl = m_pnl 
     self.SetSizer(self.boxSizer) 

class MainFrame(wx.Frame): 

    def __init__(self): 
     wx.Frame.__init__(self, None, title='Test') 
     panel = MyPanel(self) 
     self.Show() 


if __name__ == '__main__': 
    app = wx.App(False) 
    frame = MainFrame() 
    app.MainLoop()
