Graphical user interface tkinter Label of Label Use Import tkinter modular
from tkinter import * Building window objects root = Tk() Window property settings # Window title root.title(' Window title ')# Window size root.geometry('200x300')# Set the window background color root.configure(bg = "blue")# Change window icon root.iconbitmap('icon File path ')# Keep the program running root.mainloop()The results are illustrated
Mark： Generally set the title for the window 、 The background color 、 size 、 Icons should be enough . It should be noted that the function for setting the window size geometry The parameter unit of is pixels , The effect is the window size when the running program appears . Function to set the background color configure The argument to is in the form of a key value . You can also limit the window size , For example, limit window maximization 、 To minimize the ：maxsize、minsize. When you run the program , Maximize rendered windows 、 To minimize the ：state、iconify. You can also change the default icon of the window ：iconbitmap.
label labelText and pictures can be placed inside the label .
Text label
Label(root,text='Hello tkinter', fg='white',bg='red', height=1,width=15,anchor='nw').pack()The results are illustrated
If the text is long
such as text=‘I will white a text, in which there are many words,and the method of the condition will be given’
Label(root, text='I will white a text, in which there are many words,and the method of the condition will be given', fg='white',bg='red', height=8,width=15,anchor='nw', wraplength=100,justify='left').pack()The results are illustrated
Mark： When we place text in a label , To keep the text in place , Normal display , Need to use label Some properties of . Setting up label The height of the label 、 Width 、 The background color ：height、weight、bg. Set the color of the font 、 size ：fg、font. The text is in label Location in label ：anchor. Alignment of content in text ：justify. If the text content is too long , Can be adjusted height、width、wraplength. among wraplenght Indicates the number of pixel units followed by line breaks . When text is placed in the label ,height、width How many character units does it refer to .
Add ： The units involved are geometry、height、width、wraplenght.geometry Used to set the window size , Is the pixel unit .wraplength It refers to how long a paragraph of text begins to wrap , Refers to the unit of pixels . and height、width On the label label When placing text in , It refers to the unit of characters , Used for setting up label The size of the label , It is convenient to display the text content .
Picture label
python Built in picture ( bitmap attribute )
Label(root,bitmap='error').pack()The results are illustrated
error It can be replaced by hourglass、info、questhead wait
image Property display image
establish image object
im = PhotoImage(file = r'C:\Users\Administrator\Desktop\ animal .png')establish label object
Label(root,image = im).pack()The results are illustrated
Mark： On the label label in , Use python Built in pictures , You need to use properties bitmap,bitmap The value of can find related documents . If you want to put your own photos , Need to use image attribute ,image The value of is a image object . Utility class PhotoImage Convert the corresponding picture into image Object use .
supplement
Combination of text and pictures attribute compound
xtext=' Chinese style 'im = PhotoImage(file = r'C:\Users\Administrator\Desktop\ Magpie peach blossom folding fan .png')Label(root,text=xtext,fg='red',font=(' Regular script ',40), image = im,compound='center').pack()The results are illustrated
Mark： On the label label Put both text and pictures in , To use label Of compound attribute .
Use tkinter Some small problems solved Label Of weight ParametersIt was also used in a previous project label display picture ,height Parameters can be used
tk.Label(self.root, image=self.p[i] ,width = 200,height = 200 ).place(x =x0-20,y=y0+50)But the recently done prompt does not have this parameter , So you can't change the size of the displayed picture , It took a long time to find a solution , Finally, change the size of the image through other libraries , Then it will show back , You can choose which image you want to use to transfer to other functions
def photo_show(p): # Storage path of image to be processed im = Image.open(p) # Resize Picture size , The entry parameter is a tuple, New picture size imBackground = im.resize((200, 200)) # The storage path of the processed picture , And storage format imBackground.save('show.png')The above is personal experience , I hope I can give you a reference , I also hope you can support the software development network .
