I have a program I'm testing in Python 3.1 in Windows XP using tkinker
to dispay random quotes. It works except for two things.
1) The program displays a random quote of the day when it's invoked,
but I want to have a "Next quote" button so that additional random
quotes can be displayed. Here are the parts of the program were I get
the first quote:
################################
def get_random_quote(): # create a function
to get a random quote from quote_dict
rq = (random.randrange(len(quote_dict))+1) # pick a
random entry from the quote dictionary
return rq
def output_quote():
rand_quote = get_random_quote() # get a random quote
quote = quote_dict[rand_quote][1] # put the quote in a
string varible
author = quote_dict[rand_quote][0] # put the author in a
string variable
om = (quote+"\n\n"+author) # format the output
string variable
return om
out_message = output_quote()
msg_widget = Message(win, anchor = NW, justify = LEFT, width = 1000,
bd= 2, bg = "white",
relief = SOLID, text=out_message)
################################
Here is my button the get the next quote:
################################
next_button = Button(win, text="Next Quote", command=output_quote()) #
create button widget
next_button.pack(side=LEFT)
################################
Even though I'm calling the same function, output_quote(), the screen
is not getting refreshed. There is no error, just the new quote is not
showing up in the message box. How do I refresh the message box?
2) The message widget seems to be sizing based on the size of the text
you present to it. For a small quote it's small, for a longer quote it
streches out wide and then adds more lines. I'd like to present a
consistent sized message box when the program is run, no matter if the
text is small or large, but I can't figure out how to do that. In
other words, I'd like the message widget in question 1 above to
display as a box capable of storing, say, 1,000 characters, even if I
only give it 100, so the program looks the same every time it's
invoked. Is there a way to make a default sized message widget?
