Creating a GUI program instance using the Tkinter module in Python

Use the Tkinter module to create a simple GUI program.

Tkinter's widgets are: Button, Canvas, Checkbutton, Entry, Frame, Label, Listbox, Menu, Menubutton, Message, Radiobutton, Scales, Scrollbar, TEXT, TopLevel and so on.

Cases:

The code is as follows:

# This program displays an empty window.
Import Tkinter
def main ():
Main_window = tkinter.tk ()
Tkinter.mainloop ()
Main ()

Example 2:

The code is as follows:

Import Tkinter
Class Mygui:
def __init__ (self):
# Create the main window widget.
Self.main_window = tkinter.tk ()

# Enter the Tkinter main loop.
Tkinter.mainloop ()
# Create An instance of the Mygui class.
My_gui = Mygui ()

Example 3:

The code is as follows:

# The program displays a label with text.
Import Tkinter
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
# Create a Label widget containing the text ' Hello world '
Self.label = Tkinter.label (Self.main_window, text= ' Hello world! ')
# Call the Label widget ' s pack method.
Self.label.pack ()
# Enter the Tkinter main loop.
Tkinter.mainloop ()
# Create An instance of the Mygui class.
My_gui = Mygui ()

Example 4:

The code is as follows:

Import Tkinter
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.label1 = Tkinter.label (self.main_window,text= ' Hello world! ')
Self.label2 = Tkinter.label (self.main_window,text= ' This was my GUI program. ')
Self.label1.pack ()
Self.label2.pack ()
Tkinter.mainloop ()
Mygui = Mygui ()

Example 5:

The code is as follows:

Import Tkinter
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.label1 = Tkinter.label (self.main_window,text= ' Hello world! ')
Self.label2 = Tkinter.label (self.main_window,text= ' This was my GUI program. ')
Self.label1.pack (side= ' left ')
Self.label2.pack (side= ' left ')
Tkinter.mainloop ()
Mygui = Mygui ()

Example 6:

The code is as follows:

Import Tkinter
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.top_frame = Tkinter.frame (Self.main_window)
Self.bottom_frame = Tkinter.frame (Self.main_window)
Self.label1 = Tkinter.label (self.top_frame,text= ' Winken ')
Self.label2 = Tkinter.label (self.top_frame,text= ' Blinken ')
Self.label3 = Tkinter.label (self.top_frame,text= ' Nod ')

Self.label1.pack (side= ' top ')
Self.label2.pack (side= ' top ')
Self.label3.pack (side= ' top ')

Self.label4 = Tkinter.label (self.bottom_frame,text= ' Winken ')
Self.label5 = Tkinter.label (self.bottom_frame,text= ' Blinken ')
Self.label6 = Tkinter.label (self.bottom_frame,text= ' Nod ')

Self.label4.pack (side= ' left ')
Self.label5.pack (side= ' left ')
Self.label6.pack (side= ' left ')

Self.top_frame.pack ()
Self.bottom_frame.pack ()

Tkinter.mainloop ()
Mygui = Mygui ()

Button widget and Information dialog box
Use the Showinfo function of the Tkmessagebox module to display the Information dialog box.
Cases:

The code is as follows:

# The program demonstrates a Button widget.
# When the user clicks the button, a Info dialog box is displayed.
Import Tkinter
Import Tkmessagebox
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.my_button = Tkinter.button (Self.main_window, text= ' Click me! ', command=self.do_something)
Self.my_button.pack ()
Tkinter.mainloop ()
def do_something (self):
Tkmessagebox.showinfo (' Response ', ' Thanks for clicking the button. ')
Mygui = Mygui ()

Example 2:

The code is as follows:

Import Tkinter
Import Tkmessagebox
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.my_button = Tkinter.button (Self.main_window, text= ' Click me! ', command=self.do_something)
Self.quit_button = Tkinter.button (self.main_window,text= ' quit ', command=self.main_window.quit)
Self.my_button.pack ()
Self.quit_button.pack ()
Tkinter.mainloop ()
def do_something (self):
Tkmessagebox.showinfo (' Response ', ' Thanks for clicking the button. ')
Mygui = Mygui ()

Get Input with entry widget
The Entry widget is a rectangular area that users can enter. The input data can be retrieved using the Get method of the entry widget.
Cases:

The code is as follows:

Import Tkinter
Import Tkmessagebox
Class Kilogui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.top_frame = Tkinter.frame (Self.main_window)
Self.bottom_frame = Tkinter.frame (Self.main_window)
Self.label = Tkinter.label (self.top_frame,text= ' Enter a distance in kilometers: ')
Self.entry = Tkinter.entry (self.top_frame,width=10)
Self.button1 = Tkinter.button (self.bottom_frame,text= ' Convert ', Command=self.convert)
Self.button2 = Tkinter.button (self.bottom_frame,text= ' Quit ', command=self.main_window.quit)

Self.label.pack (side= ' left ')
Self.entry.pack (side= ' left ')
Self.button1.pack (side= ' left ')
Self.button2.pack (side= ' left ')
Self.top_frame.pack ()
Self.bottom_frame.pack ()

Tkinter.mainloop ()
def convert (self):
Kilo = float (self.entry.get ())
Miles = kilo*0.6214
Tkmessagebox.showinfo (' Result ', str (kilo) + ' kilometers is equal to ' +str (miles) + ' Miles ')

Mygui = Kilogui ()

Example 2:

The code is as follows:

Import Tkinter
Import Tkmessagebox
Class Kilogui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.top_frame = Tkinter.frame (Self.main_window)
Self.mid_frame = Tkinter.frame (Self.main_window)
Self.bottom_frame = Tkinter.frame (Self.main_window)

Self.label1 = Tkinter.label (self.top_frame,text= ' Enter a distance in kilometers: ')
Self.entry = Tkinter.entry (self.top_frame,width=10)

Self.button1 = Tkinter.button (self.bottom_frame,text= ' Convert ', Command=self.convert)
Self.button2 = Tkinter.button (self.bottom_frame,text= ' Quit ', command=self.main_window.quit)

Self.label2 = Tkinter.label (self.mid_frame,text= ' converted to Miles: ')
Self.value = Tkinter.stringvar ()
Self.label3 = Tkinter.label (self.mid_frame,textvariable=self.value)

Self.label1.pack (side= ' left ')
Self.entry.pack (side= ' left ')

Self.button1.pack (side= ' left ')
Self.button2.pack (side= ' left ')

Self.label2.pack (side= ' left ')
Self.label3.pack (side= ' left ')

Self.top_frame.pack ()
Self.mid_frame.pack ()
Self.bottom_frame.pack ()

Tkinter.mainloop ()
def convert (self):
Kilo = float (self.entry.get ())
Miles = kilo*0.6214
Self.value.set (Miles)

Mygui = Kilogui ()

radio button and check button

The code is as follows:

Import Tkinter
Import Tkmessagebox
Class Mygui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.top_frame = Tkinter.frame (Self.main_window)
Self.bottom_frame = Tkinter.frame (Self.main_window)

Self.radio_var = Tkinter.intvar ()
Self.radio_var.set (1)
SELF.RB1 = Tkinter.radiobutton (self.top_frame,text= ' Option 1 ', variable=self.radio_var,value=1)
SELF.RB2 = Tkinter.radiobutton (self.top_frame,text= ' Option 2 ', variable=self.radio_var,value=2)
SELF.RB3 = Tkinter.radiobutton (self.top_frame,text= ' Option 3 ', variable=self.radio_var,value=3)
