Label
They are created as follow: var1 = IntVar() var2 = IntVar() Then, two check buttons: cb1 = Checkbutton(Mazen, text='Python', font=(20), variable=var1, command=type) cb1.place(x=5, y=5) cb2 = Checkbutton(Mazen, text='Java', font=(20), variable=var2, command=type) cb2.place(x=5, y=30) 13 Then, __________: lbl = Label(Mazen, text='', font=(20)) lbl.place(x=30, y=100)
Label
Then, Function that RUN with check buttons: def type(): a = var1.get() b = var2.get() if a==1 and b==0: lbl.config(text='You if a==1 and b==1: lbl.config(text='You if a==0 and b==0: lbl.config(text='You if a==0 and b==1: lbl.config(text='You 14 _______ select Python') select Python and Java') do not select') select Java')

Study Notes
Tkinter Framework
- Tkinter is a Python library used for creating graphical user interfaces (GUIs).
- It is used to create windows, buttons, labels, and other graphical elements.
Creating a Tkinter Window
- To create a Tkinter window, you need to import the Tkinter module using
from tkinter import *. - Create a Tkinter object using
Cairo = Tk(). - Set the window's geometry using
Cairo.geometry('400x200'). - Start the main event loop using
Cairo.mainloop().
Creating Widgets
- Widgets are graphical elements such as buttons, labels, and entries.
- Create a label using
lbl1 = Label(Cairo, text='X =', font=('courier', 20, 'bold')). - Create an entry using
inp = Entry(Cairo, font=('courier', 20, 'bold'), width=10). - Create a button using
btn = Button(Cairo, text='X^2 - 3X + 4 =', font=('courier', 20, 'bold'), command=estimate).
Creating a Combobox
- Create a combobox using
cm = ttk.Combobox(Cairo, font=('courier', 16)). - Set the combobox values using
cm['values']=tuple([200, 400, 600]).
Capturing an Image
- Create a function to capture an image using a camera using
CameraCapture(). - Use OpenCV to capture an image using
CameraImage = cv2.VideoCapture(0). - Resize the image using
imr = cv2.resize(im, (a, a)).
Selecting a Language
- Create a function to select a language using
type(). - Use IntVar() to create variables for checkbuttons.
- Create checkbuttons using
cb1 = Checkbutton(Mazen, text='Python', font=(20), variable=var1, command=type).
Using Radiobuttons
- Create a function to select a language using
type(). - Use IntVar() to create a variable for radiobuttons.
- Create radiobuttons using
cb1 = ttk.Radiobutton(Mazen, text='Python', value=1, variable=var, command=type).
Using Spinbox and Scale Bars
- Create a spinbox using
sp = Spinbox(Mazen, from_=0, to=100, command=type_no1). - Create scale bars using
sc1 = Scale(Mazen, from_=1, to=100, orient=HORIZONTAL, command=type_no2)andsc2 = Scale(Mazen, from_=1, to=100, orient=VERTICAL, command=type_no2). - Create a label using
lbl = Label(Mazen, text='', font=('bold', 40)).
Functions of Spinbox and Scale Bars
- Create a function for the spinbox using
def type_no1(): a = sp.get() lbl.config(text=str(a)). - Create a function for the scale bars using
def type_no2(self): b = sc1.get() c = sc2.get() lbl.config(text=str(b)+', '+str(c)).
Test your knowledge of using radio buttons in Python Tkinter GUI applications. Determine the expected outcome based on the given code snippet and understand how the IntVar variable and Radiobutton widgets interact.
