wxPython: Nesting GridBagSizers not spanning?

I've g0t a GridBagSizer (folderBagSizer)within an existing GridBagSizer (sizer)... now I am trying to populate the nested sizer (folderBagSizer) with some labels. They are showing up UNDER the sizers...?

# Create static box
self.sb_ExtractOptions = wx.StaticBox(panel, label="Options for Extract", 
    size=(100,100))
folderBoxSizer = wx.GridBagSizer(4, 9)
folderBoxSizer.Add(self.sb_ExtractOptions, pos=(0,0), span=(1,4), 
    flag=wx.EXPAND, border=10)

# Create the options
label_OptionsCreated = wx.StaticText(panel, label="Created:")
label_OptionsInserted = wx.StaticText(panel, label="Inserted:")
label_Option开发者_运维问答sModified = wx.StaticText(panel, label="Modified:")

# Add them to the sizer (folderBoxSizer)
folderBoxSizer.Add(label_OptionsCreated, pos=(1, 0), flag=wx.LEFT|
    wx.ALIGN_CENTER_VERTICAL|wx.TOP, border=3)
folderBoxSizer.Add(label_OptionsInserted, pos=(2, 0), flag=wx.LEFT|
    wx.ALIGN_CENTER_VERTICAL|wx.TOP, border=3)
folderBoxSizer.Add(label_OptionsModified, pos=(3, 0), flag=wx.LEFT|
    wx.ALIGN_CENTER_VERTICAL|wx.TOP, border=3)

folderBoxSizer.AddGrowableCol(2)
sizer.Add(folderBoxSizer, pos=(2, 0), span=(1,6),flag=wx.TOP|wx.LEFT|wx.RIGHT|wx.EXPAND|wx.ALIGN_CENTER_VERTICAL, border=10)


sizer.AddGrowableCol(2)
panel.SetSizer(sizer)

Thanks in advance. :)

Figured it out, and of course, total noob logic problem.

    # Create static box
    self.sb_ExtractOptions = wx.StaticBox(panel, label="Options for Extract", size=(100,100))
    sbs_ExtractOptions = wx.StaticBoxSizer(self.sb_ExtractOptions, wx.VERTICAL)
    OptionBoxSizer = wx.GridBagSizer(4, 9)

    # Create the options
    logicList = ['<', '<=', '=', '>', '>=']

    sizerIndexX = 0

    # Created
    label_OptionsCreated = wx.StaticText(panel, label="Created:")
    combo_LogicalCreated = wx.ComboBox(panel, 1, "", (25, 25), (60, 25), logicList, wx.CB_DROPDOWN)
    combo_LogicalCreated.Select(1)
    self.tc_DaysAgoCreated = wx.TextCtrl(panel)
    label_DaysAgoCreated = wx.StaticText(panel, label="days ago")
    # Add them to the sizer (optionBoxSizer)
    OptionBoxSizer.Add(label_OptionsCreated, pos=(sizerIndexX, 0), flag=wx.ALL|
        wx.ALIGN_CENTER_VERTICAL|wx.ALIGN_RIGHT, border=0)
    OptionBoxSizer.Add(combo_LogicalCreated, pos=(sizerIndexX,1), flag=wx.ALIGN_CENTER_VERTICAL|wx.ALL, border=1)
    OptionBoxSizer.Add(self.tc_DaysAgoCreated, pos=(sizerIndexX, 2), flag=wx.ALL|
        wx.ALIGN_CENTER_VERTICAL|wx.ALIGN_LEFT, border=0)
    OptionBoxSizer.Add(label_DaysAgoCreated, pos=(sizerIndexX,3), flag=wx.ALL|
        wx.ALIGN_CENTER_VERTICAL|wx.ALIGN_LEFT, border=0)

   sbs_ExtractOptions.Add(OptionBoxSizer, flag=wx.TOP|wx.LEFT|wx.RIGHT|wx.EXPAND|wx.ALIGN_CENTER_VERTICAL, border=10)
    sizer.Add(sbs_ExtractOptions, pos=(2, 0), span=(1,6),flag=wx.TOP|wx.LEFT|wx.RIGHT|wx.EXPAND|wx.ALIGN_CENTER_VERTICAL, border=10)

I was adding the sizer for the static box to the wrong sizer initially -- the way it needs to work is to:

1. Create the static box (self.sb_ExtractOptions)
2. Create the sizer that will live within it, in this case a StaticBoxSizer. (sbs_ExtractOptions)
3. Create the grid for my objects to layout within the sizer (OptionBoxSizer)
4. Create GUI elements and add them to OptionBoxSizer
5. Add the OptionBoxSizer to the StaticBoxSizer (i.e. add what you did in step 4 to step 2)
6. Add the StaticBoxSizer to the panel's main sizer (sizer, in this case)
7. Drink a beer, or 5. And celebrate your new lesson like I did in paying freaking attention to what you are doing!
