Tkinter module (1)-Introduction and Label

There are 15 controls for us to use in the Tkinter module. Let's give a brief introduction to these controls first.

1)Button

Provide a button that triggers an event when clicked.

2)Canvas

Provide a canvas, which is the size of the GUI interface.

3)Tk

Create the main application window.

4)Check button

Selectable multiple buttons.

5)Entry

Provides an input box to enter information from the keyboard.

6)Frame

Provides a window that can host other controls.

7)Label

Provide a label that can display text or images.

8)Listbox

Provides a list box from which one can be selected.

9)Menu

Provides a menu bar to select one.

10)Menubutton

Menu button.

11)Message

Message text box.

12)Radiobutton

Radio button, you can only select one of multiple buttons

13)Scale

Slider.

14)Scrollbar

scrollbar.

15)Text

Provides a text for the user to enter information.

16)Toplevel

Create a pop-up window.

1.Create window

To create a graphical interface, we must first have a window for us to add other controls. To add a window, use tkinter's Tk() function. The syntax format is:

 window=tkinter.Tk()window.mainloop()

window is the name of the window we created, followed by the usage method. tkinter.mainloop() registers the call manager to respond to the event, that is, to start this window. Look at the code below:

 importtkinterwindow=tkinter.Tk()window.mainloop()

Running results:

If you want to manage the maximum and minimum sizes of the window, use the following method:

 importtkinterwindow=tkinter.Tk()window.minsize(366,366)#Minimum size window.maxsize(566,566)#Maximum size window.mainloop()

2.Label component

If we want to add text or pictures in the window, we can use the Label control as follows:

 importtkinterdefmain():win=tkinter.Tk()win.minsize(366,366)#Minimum size win.maxsize(888,888)#Maximum size area_one=tkinte r.Label(win,text='Thisisarea_one',font=(Chinese regular script,20),fg=red)area_one.pack(side='left')area_two=tkinter.Label( win,text='Thisisarea_two',font=(黑体,20),fg=blue)area_two.pack(side='right')area_three=tkinter.Label(win,text='Thisisarea_three',font=(宋体,20 ),fg=black)area_three.pack()win.mainloop()if__name__=='__main__':main()

The running result is as shown in the figure:

Let's explain this example. The form of component addition is:

 Component name=tkinter.Label (placed window, text or picture, additional content) component name.pack(side='position')

First, we fill in the corresponding content according to the corresponding information, and then we can locate the location information through pack. We can also use top and bottom location information.
