Scrollbars don't appear when expanding FoldPanelBar in wxPython

Question

When the fold panels expand, they go beyond the borders of the frame, and scroll bars do not appear. I tried using the ScrolledPanel but did not help. Any idea what I'm missing here?

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()

Do not use the default FoldPanelBar size. For some reason, the widget seems to be acting stupid. If you specify a size, the scroll bars will display correctly.

 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() 

You may consider sending errors for this to the wxPython project.
