Hello all,
Please review these two piece of code and see why the latter doesnt resize as desired. When I add panel I find result becomes very strange. How can I resize widgets in a panel without such problem? Below are the two codes for simple editor

PROBLEMATIC CODE

import wx
ID_NEW = 10
ID_OPEN = 11
ID_CLOSE = 12
ID_SAVE = 13
ID_SAVE_AS = 14
ID_PAGE_SETUP = 15
ID_PRINT_PREVIEW = 16
ID_PRINT = 17
ID_EXIT = 18
ID_UNDO = 19
ID_REDO = 20
ID_SEARCH = 21
ID_SPELL = 22
ID_HELP = 23
class TextEditor(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(350, 600))
        # self/Text editor is now a Window with all attribute of a frame
        # create status bar
        self.CreateStatusBar()
        # set default status bar string
        self.SetStatusText("For help press F1")
        # define sizers
        vbox = wx.BoxSizer(wx.VERTICAL)
        hbox = wx.BoxSizer(wx.HORIZONTAL)
                
        #Add menu
        #define menubar and menu
        menubar = wx.MenuBar()
        # attach menubar to the frame
        self.SetMenuBar(menubar)

Just to add on that, I want to put my icons in a folder named icons in the same folder as my script. How do I reference them in code without error "File so and so.png does not exist"
Thanks again

On Windows you do a "./icons/myicon.ico" for example.
