running curses program from gui program

[jackj]

Ubuntu 10.04, Python 2.6.

When trying to execute a curses module from a Tkinter module, it begins running, but have to hit icon on bottom panel to make it visible. Can someone help me get it visible without having to hit the icon.

I am attaching two files, one with the GUI Tkinter module called testing.py, and a second curses module called ncurses.py. If you start testing, there is a button "RUN CURSES." When you hit the button it appears nothing happens, but really it got loaded, just not visible.

This is my first time with attachments, so I hope they attach.

I guess nobody got the attachments, since I can't find them. Since it's in two files, I'll have to put the code right here as two files. I can only hope that someone doesn't feel too inconvenienced by dealing with it this way. For anyone who takes the time, let me thank you in advance.

The second file will have to be saved to ncurses.py to work as-is.



#!/usr/bin/env python

from Tkinter import *
import ncurses

class StatusBar(Frame):
def __init__(self, master):
Frame.__init__(self, master)
self.label = Label(self, bd=1, relief=SUNKEN, anchor=W)
self.label.pack(side=BOTTOM, fill=X)

def set(self, format, *args):
self.label.config(text=format % args)
self.label.update_idletasks()

def clear(self):
self.label.config(text="")
self.label.update_idletasks()

def doCurses():
g = ncurses.gojo()
g.start()

root = Tk()
root.option_add('*font', ('verdana', 16, 'bold'))

#get screen dimensions:
sw = root.winfo_screenwidth()
sh = root.winfo_screenheight()
frame = Frame(root, width=sw, height=sh, bd=1)
#set to full screen:
root.geometry("%dx%d+0+0" % (sw, sh))

frame.pack()

# create a menu
menu = Menu(root)

filemenu = Menu(menu)

menu.add_command(label="RUN CURSES", command=doCurses)

status = StatusBar(root)

root.config(menu=menu)

mainloop()

This is the second file, which needs to be named ncurses.py:

Okay, I've got down to one file, which should be a help. Please help.
