[@sarthaksrivastava6282]

how can we make the buttons deselect themselves if we click on them again? like I tried making a multi correct MCQ, I assigned different variables to different buttons so one can select multiple buttons but how to deselect if we click on it again??

[@Codemycom]

Like I said, create a function that gets called every time the button is clicked that keeps track of the current state of the button and acts accordingly to deselect itself.

[@advays9815]

sir? can we display the options and not have the value that we set be displayed on the screen to the user?

[@Codemycom]

Can't you tell from the video?

[@akilamp8470]

@@Codemycom I managed to figure it out. Thank you! Also can you tell me how to pass the value you get when you click a radiobutton in a seperate variable?

[@letsarray5712]

i want ask you, why you use lambda in your command?

[@Codemycom]

Because that’s how it works.

[@Harish-ou4dy]

I used grid to update the labels containing string, every time label gets updated there are some fragments of text of previous label seen beneath the current one (for ecample if first label was Pepperoni then next was egg), so "P" and "i" of Pepperoni will still be visible when egg is the new updated label.

[@Codemycom]

look into the .destroy() function.

[@chinmaykulkarni7835]

So if I click a radio button it will consider one time entering in function or continuously as long as it is activated?

[@durgeshchandrapatel5943]

Only at the time when it is toggled like on or off.

[@bassusdandoti3073]

[@lawrencetheguywithjustfact4767]

Hi. I have stupid question. IntVar, Radiobutton, title, Label, .get on your editor have blue color. I'm using Pycharm, how to change colors for Tkinter commands? Thanks

[@mdzohaib7368]

Sir can u tell me how to remove the current label nd whenever i click on any other radiobutton the label gets overwrite rather than showing its mode in next row?

[@mdzohaib7368]

I think there must be some command like label.rem smthng to remove the current label and replace in same row with other label whenever i click on other radiobutton.

[@Codemycom]

You can usually .config things to change them.

[@uvrays045]

If i click a button, how do i make the screen of the gui clear of ? Can u plz help ?

[@infinitespace1982]

do u have any other tutorial in youtube ?

Yes, I have hundreds: kzbin.info

[@dead1ock284]

So i did the same as you with the for loop but i had 7 radio buttons, i even set the value of the radio buttons variable to '1' but every time i run the program, all the buttons are marked but when i click on one button then all of the buttons get unmarked like it needs to be. how do i fix this problem?

[@Codemycom]

There's a problem with your code, but I don't know what.

[@dead1ock284]

@@Codemycom never mind i managed to figure it out but thanks anyways for replying to my comment :)

[@ogspeace]

is there a difference between root.mainloop() and just calling mainloop() ? i noticed that you used `mainloop()` instead of `root.mainloop()` starting w/ this vid (and onwards). also, do you have a tutorial on implementing tkinter in classes? (oop). thanks.

[@Codemycom]

Videos with classes will be coming soon :-)

[@dong8912]

Great Video. I have one question though, When I tried to create radio buttons within a function, I can't seem to get the IntVar variable to change and it always stays as the default value, regardless of which radio button is selected. Is there a way to fix this?

[@Codemycom]

I think there must just be a typo in your code

[@dong8912]

@@Codemycom Nope, no typos. My script includes 6 radio buttons in total, 3 of which are outside a function and the other 3 in a function - the function is called by clicking a button, which opens up a new window that contains the other 3 radio buttons. All radio button lines look exactly the same, with only the values and texts being different. I even tried using global variables but that still didn't work. I think it may be helpful to mention that i am also using IDLE to run my scripts

[@dong8912]

So I managed to fix this issue, and also a bunch of other issues relating to some widgets not working in a function-generated window. Essentially, The very first window opened in the script uses the command: root = Tk(). since I'm creating more than one window concurrently, instead of using: window = Tk() to create that window, I instead use: window = Toplevel(). Apparently tkinter is designed such that only one Tk() window can be opened at a time, and to open multiple windows, I need to use Toplevel(). But yeah this fixes the issue of the radio buttons not working. Also I just realised you already made a video covering this and that I totally forgot.

[@Codemycom]

@@dong8912 Glad you got it sorted out!

[@dong8912]

I never use place, but you use it with the radio button the same way you use it with every other widget.

[@Codemycom]

Two things...your r=IntVar needs to be r = IntVar() you fogot the parenthesis. Next, make the radiobutton variable global. So above the RadioButton code, go: global r r = IntVar()

[@pro_fessor.]

Why using mainloop() Instead of root.mainloop() In las line

[@Codemycom]

should probably be root.mainloop()

[@Harish-ou4dy]

strangely enough, text=r.get() doesnt work when using r as a StringVar(). Even after setting r.set="sample string"... Nothing shows up, when tried to check by print(r.get()), its a blank string.
