Python noob here. I've created a simple tkinter app with 6 frames. Using multiple frames was the easiest way I could find to get all of the widgets to line up.
I want to have a text entry field in one of the frames that can be updated by other functions in the code. However, no matter what I try, I cannot get blah.set( "blah" ) to work.
I'm not using the self/parent stuff because I have not been able to figure that out yet. Here's what I've got:
def Next () :
glob_current_company_display.set( "test" )
def makeWindow () :
win = Tk()
win.title('Finder')
win.geometry('+842+721')
# ************************************************************************
# Frame 2
frame2 = Frame(win)
button_03 = Button(frame2, text="Next", width=10, command=Next)
button_03.pack(side=LEFT)
# ************************************************************************
# Frame 5
frame5 = Frame(win)
co_name_label = Label(frame5, text="Company Name: ", justify=LEFT)
co_name_label.pack(side=LEFT)
global glob_current_company_display
glob_current_company_display = StringVar()
co_name_entry = Entry(frame5, width=50, textvariable=glob_current_company_display)
co_name_entry.pack(side=LEFT)
# ************************************************************************
# Pack the frames
frame5.pack(side=TOP, pady=5, padx=5)
frame2.pack(side=TOP, pady=5, padx=5)
return win
win = makeWindow()
win.mainloop()
You probably should investigate the "self/parent stuff". It's comes in very handy for this kind of stuff. For now: you could put the creation of the global variable before the button_03
that has Next()
as command (which has a reference to te global in it).
from Tkinter import *
def Next () :
glob_current_company_display.set( "test" )
def makeWindow () :
win = Tk()
win.title('Finder')
win.geometry('+842+721')
global glob_current_company_display
glob_current_company_display = StringVar()
# ************************************************************************
# Frame 2
frame2 = Frame(win)
button_03 = Button(frame2, text="Next", width=10, command=Next)
button_03.pack(side=LEFT)
# ************************************************************************
# Frame 5
frame5 = Frame(win)
co_name_label = Label(frame5, text="Company Name: ", justify=LEFT)
co_name_label.pack(side=LEFT)
co_name_entry = Entry(frame5, width=50, textvariable=glob_current_company_display)
co_name_entry.pack(side=LEFT)
# ************************************************************************
# Pack the frames
frame5.pack(side=TOP, pady=5, padx=5)
frame2.pack(side=TOP, pady=5, padx=5)
return win
win = makeWindow()
win.mainloop()
