Use the Tkinter module in Python to create a GUI program instance, pythontkinter

Use the Tkinter module to create a simple GUI program.

Tkinter's Widgets include buttons, Canvas, Checkbutton, Entry, Frame, Label, Listbox, Menu, Menubutton, Message, Radiobutton, Scales, Scrollbar, TEXT, and Toplevel.

Example:
Copy codeThe Code is as follows:
# This program displays an empty window.
Import Tkinter
Def main ():
Main_window = Tkinter. Tk ()
Tkinter. mainloop ()
Main ()

Example 2:
Copy codeThe 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:
Copy codeThe 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:
Copy codeThe 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 is my GUI program .')
Self. label1.pack ()
Self. label2.pack ()
Tkinter. mainloop ()
Mygui = MyGUI ()

Example 5:
Copy codeThe 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 is my GUI program .')
Self. label1.pack (side = 'left ')
Self. label2.pack (side = 'left ')
Tkinter. mainloop ()
Mygui = MyGUI ()

Example 6:
Copy codeThe 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.
Example:
Copy codeThe Code is as follows:
# The program demonstrates a Button widget.
# When the user clicks the button, an 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:
Copy codeThe 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 ()

Use the Entry Widget to obtain the input.
The Entry Widget is a rectangular area that you can enter. You can use the get method of the Entry Widget to retrieve the input data.
Example:
Copy codeThe 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:
Copy codeThe Code is as follows:

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 and Check buttons
Example:
Copy codeThe 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. rb= 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)

Self. rb1.pack ()
Self. rb2.pack ()
Self. rb3.pack ()

Self. OK _button = Tkinter. Button (self. bottom_frame, text = 'OK', command = self. show_choice)
Self. quit_button = Tkinter. Button (self. bottom_frame, text = 'quit', command = self. main_window.quit)

Self. OK _button.pack (side = 'left ')
Self. quit_button.pack (side = 'left ')

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

Tkinter. mainloop ()

Def show_choice (self ):
TkMessageBox. showinfo ('selection ', 'you selected optioin' + str (self. radio_var.get ()))
