Python event & wxPython question:

[bob]

Here's a piece of my code. My question is this... It's simple, but I
can't seem to find an example.. On a frame, I have a button, and a
textbox.. I want to hit a button, and that event will call a function,
in that function I want the value that was in the textbox.. I can't
figure out how to access that value in the function that was called...
Please help.. This is the code, It's just test code, trying to figure
out some basic funtionality. When the onbtnTest function is called,
I'd like to have access to the value in txtText ...

from wxPython.wx import *


ID_ABOUT = 101
ID_EXIT  = 102
ID_BSTUFF = 103

class MyFrame(wxFrame):
    def __init__(self, parent, ID, title):
        wxFrame.__init__(self, parent, ID, title,
                         wxDefaultPosition, wxSize(400, 350))
        self.CreateStatusBar()
        self.SetStatusText("This is the statusbar")
        menu = wxMenu()
        menu2 = wxMenu()

        menu.Append(ID_EXIT, "E&xit", "Terminate the program")
        menu2.Append(ID_ABOUT, "&About", "More information about this
program")
        
        
        menuBar = wxMenuBar()
        menuBar.Append(menu, "&File");
        menuBar.Append(menu2, "&Help");
        self.SetMenuBar(menuBar)

        panel = wxPanel(self, -1)
        
        btnTest=wxButton(panel,ID_BSTUFF," Go ")

                              "About Me", wxOK | wxICON_INFORMATION)
        dlg.ShowModal()
        dlg.Destroy()
