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:
Copy Code code as follows:
# This is displays an empty window.
Import Tkinter
def main ():
Main_window = tkinter.tk ()
Tkinter.mainloop ()
Main ()
Example 2:
Copy Code code 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 Code code 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 Code code 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 are my GUI program. ')
Self.label1.pack ()
Self.label2.pack ()
Tkinter.mainloop ()
Mygui = Mygui ()
Example 5:
Copy Code code 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 are my GUI program. ')
Self.label1.pack (side= ' left ')
Self.label2.pack (side= ' left ')
Tkinter.mainloop ()
Mygui = Mygui ()
Example 6:
Copy Code code 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 Info dialog box
Use the Showinfo function of the Tkmessagebox module to display the Information dialog box.
Cases:
Copy Code code 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 ', ' for clicking the button. ')
Mygui = Mygui ()
Example 2:
Copy Code code 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 ', ' for clicking the button. ')
Mygui = Mygui ()
Get Input with entry widget
The Entry widget is a rectangular area that the user can enter. You can retrieve the input data using the entry widget's Get method.
Cases:
Copy Code code as follows:
Import Tkinter
Import Tkmessagebox
Class Kilogui:
def __init__ (self):
Self.main_window = tkinter.tk ()
Self.top_frame = Tkinter.frame (Self.main_window)
