Preface
Record and display the file path opened by clicking
Record the file path and folder path clicked
Record file path , stay text It shows that , Delete and close windows
PrefaceWe need to pay attention to , Of instantiated text components insert、delete The operations such as index** Floating point type, not integer type **,（1.0,2.0） Indicates the operation on the first line , To close a window, you need to know that the object of action is the most fundamental window , Not a certain one. Frame.
Text Several main setting parameters ：
The first parameter ： Form or frame variable
state： Controls whether you can modify text Text content ,normal,disable
width,height： Width and height
text A major component of ：
txt_entry=Text(wintool,state,width,height).pack()txt_entry.get(start_index,end_index)# Read text The character content in ,start_index,end_index All floating point numbers , The integer part represents a line txt_entry.delete(start_index,end_index) # Delete text txt_entry.insert(start_index,' Text content ')# Yes text Insert text content , If it is the end index, you can use ENDimport tkinter.filedialog as fd： Library for reading files or paths fd.askdirectory： Return to the clicked path fd.askopenfilenames()： Returns the names of multiple selected files txt_entry=Text(wintool,width,height,).pack(): Component instantiation and placement txt_entry( Variables after component instantiation ) Record and display the file path opened by clicking from tkinter import *import tkinter.filedialog as fdall_path = [] # Record global path def openFloder(): folder_path = fd.askdirectory(initialdir=r"D:\graduate\ Applet \ Total number of license plates and statistics of provinces ") # Open file show_folderPath.delete(0.0,END) # Empty show_folderPath.insert(0.0,folder_path) # Write path print(folder_path) all_path.append(folder_path) txt.delete(0.0,'end') txt.insert(0.0,all_path) # The first character inserted is the index , Cannot be in integer form print('all_path:',all_path) root = Tk() # Generate the main window object root.title('Demo') # Window title root.geometry('400x400') # Window size fr= Frame(root,width=200,height=200,)fr.pack(side='top',expand='yes')txt = Text(fr,bd=5)txt.pack(side='bottom')txt_txt = txt.get(0.0)print('txt_txt:',txt_txt)fr1= Frame(fr,width=100,height=30,bg='gray')fr1.pack(side='left',expand='yes')fr2= Frame(fr,width=100,height=30,bg='white')fr2.pack(side='left',expand='yes')show_folderPath = Entry(fr2)show_folderPath .pack(side='left')btn = Button(fr1,bg='orange',text =" Select File ",command = openFloder) # stay root Set a button on the window object , Used to open the file and return the selected file name btn.pack()root.mainloop() Record the file path and folder path clicked For more relevant file paths, please refer to
