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) and sc2 = 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)).
