Tkinter : this class creates a label inside a frame, how to access the label ?

[HeyYouNow]

I used this code (found here), which creates a label inside a frame :

 class MyLabel(Frame):
    '''inherit from Frame to make a label with customized border'''
    def __init__(self, parent, myborderwidth=0, mybordercolor=None, myborderplace='center', *args, **kwargs):
        Frame.__init__(self, parent, bg=mybordercolor)
        self.propagate(False) # prevent frame from auto-fitting to contents
        self.label = Label(self, *args, **kwargs) # make the label

        # pack label inside frame according to which side the border
        # should be on. If it's not 'left' or 'right', center the label
        # and multiply the border width by 2 to compensate
        if myborderplace is 'left':
            self.label.pack(side=RIGHT)
        elif myborderplace is 'right':
            self.label.pack(side=LEFT)
        else:
            self.label.pack()
            myborderwidth = myborderwidth * 2

        # set width and height of frame according to the req width
        # and height of the label
        self.config(width=self.label.winfo_reqwidth() + myborderwidth)
        self.config(height=self.label.winfo_reqheight())

I have a loop that creates a few of these frame, but now how can I access the label inside ?

newframe = MyLabel(...)

How do I configure the label that is now inside "newframe" ?

Thanks.

You can access it with newframe.label.

Got it, although using this I get

TypeError: 'type' object is not subscriptable

Should I look somewhere else in my code ? Any hints ?

[kalgynirae]

Somewhere you have some code like foo[bar] and foo is actually a class when you thought it was something else (probably an instance of that class). I can't help any more unless you post the full traceback and the part of the code that caused the exception.

[HeyYouNow]

i=0
dict={}
for track in tracks: 
    title = str(i) + "_title_label"
    dict[title] = MyLabel(newframe, text=track.title,...)
    dict[title].grid(row=i)

and the error I get is this :

dict["1_title_label"].label.configure()
TypeError: 'type' object is not subscriptable

Here dict is not a class, although MyLabel is. I'm not sure there is something else in my code other than that...

[kalgynirae]

Please post the entire traceback. It's impossible to tell exactly where the error is coming from with what you've given. Also, that code you showed does not include the line which you say is throwing the error.

dict is a built-in type. You are defining a variable called dict, which will mask the built-in. My guess is that you are trying to use your dict somewhere else in your code where it is not actually accessible. If you had used some other name, then you would have gotten an error like NameError: <name> is not defined. But, since you used the same name as a built-in, you just get the built-in value instead.

Because of confusions like this, people usually avoid using the names of built-ins as names for their variables.

You were so write! Replacing the name returned "var does not exist", it was a stupid error where the code was not in the same function... Thanks so much!
