wx.Notebook conversion

Hi,

Replace:

self.main_panel_sizer.Add(search_sizer, 1, wx.ALL, 5)

with:

self.main_panel_sizer.Add(search_sizer, 0, wx.ALL, 5)

So that the notebook expands vertically on panel:

import wx
import wx.lib.agw.flatnotebook as fnb


class TheFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "The Frame", size=(800, 600),

                          )
        self.create_menu_bar()

        search_label = wx.StaticText(self.main_panel, -1, "Search By: ")
        search_label.SetFont(search_font)

        sampleList = ['one', 'two', 'three']
        self.ch = wx.Choice(self.main_panel, -1, (100, 50), choices=sampleList)

        self.text_ctrl = wx.TextCtrl(self.main_panel, -1)

        search_sizer.Add(search_label, 0, wx.ALL, 5)
        search_sizer.Add(self.ch, 0, wx.ALL, 5)
