Open txt file through Tkinter GUI

So if you want to do something to the file the operations will happen in function openInstruktion.

def openInstrucktion():    f= open("instruktioner.txt")    #t is a Text widget    t.insert(1.0, f.read())

Or if you want to open it with an editor:

def openInstrucktion():    os.system('emacs instrucktioner.txt')

If you want to open the file with the default program, you could use the os module:

def openInstruktion():    from os import startfile    startfile("c:\\path\\to\\file")instruktionBtn = Button(root, text='Spelinstruktioner', command=openInstruktion)instruktionBtn.grid(row=6, column=0)

or, if you want to open it with a specific program, try the subprocess module:

def openInstruktion():    from subprocess import call    call("notepad c:\\path\\to\\file")instruktionBtn = Button(root, text='Spelinstruktioner', command=openInstruktion)instruktionBtn.grid(row=6, column=0)

If you want to open it in a textbox however, you could do something like this:

file = open("c:\\path\\to\\file").read()textbox.insert(0.0, file)

Your best bet would probably be to open it in the default editor (opening it with a different program may not be what people want and opening it in a textbox has poor graphics).

If you want to open the file in the default editor(it always best to use the default one only)

def openInstrucktion():    os.system('start " " instruktioner.txt')
