![]() ![]() #Tkinter popup window with entry code#When we execute the above code snippet, it will display a window. Label= Label(win, text="Click the Button to Open the Popup Dialogue", font= ('Helvetica 15 bold'))īutton= Button(win, text= "Click Me!", command= popupwin, font= ('Helvetica 14 bold')) #Create a Button Widget in the Toplevel Windowīutton= Button(top, text="Ok", command=lambda:close_win(top)) ![]() By controling the button at Parent we can change colour of Child window. b4 tk.Button (mywchild, text'Red', commandlambda:nfig (bg'red')) We can add one button from child on Parent. Here is a button to change the background colour of the child window. #Create an Entry Widget in the Toplevel windowĮntry.insert(INSERT, "Enter Your Email ID") We can add options to our child window by using config. #Define a function to open the Popup Dialogue #Define a function to close the popup window Once the popup will open, the parent window will close automatically. Through this example, we will create a popup dialog that can be triggered after clicking a button. We can close the main window while residing in a popup window by using the withdraw() method. Let us create a Python script to close the underlying or the main window after displaying the popup. For a particular application, we can trigger the popup on a button object. Popup in a tkinter application can be created by creating an instance of Toplevel(root) window. from Tkinter import class MyDialog: def init(self, parent): top self.top Toplevel(parent) Label(top, textValue).pack() self.e Entry(top). You can check this link for a more comprehensive GUI that you can create using tkinter, or simply check the tkinter documentation.We are familiar with popup and used it in many applications. ![]() Once you press ‘OK’ you’ll return back to the application screen. (3) However, if you press ‘No’, you’ll get this second message box: If you press ‘Yes’, you will exit the application. You’ll then see the following message box, where you’ll have two options to choose from. (2) Press on the ‘Exit Application’ button. (1) Run the Python code, and you’ll see this simple GUI that has a single button to exit the application: button1 = tk.Button (root, text='Exit Application',command=ExitApplication,bg='brown',fg='white') Thus, we can add more stuff on the toplevel window for building dialog boxes. The toplevel window pops up the stuff above all the other windows. We can create dialog boxes for any tkinter application using the Toplevel window and other widgets. You can control the position where your button will be displayed, by changing the numeric values (under the create_window syntax). It is generally used to interact with the user and the application interface. (4) Finally, you’ll need to add a button (aka button1) to call the ‘ExitApplication’ function/command above. else: another message box will appear on your screen to indicate that you’ll now return back to the application screen.If MsgBox = ‘yes’then the GUI will be closed.MsgBox = tk.messagebox.askquestion (‘Type here the title for your message box’,’type here the content that will be displayed within the message box’) You can edit the text within the message box: When you press on the button, a message box would appear on your screen. (3) Now you’ll need to create a function/command to be called by the Exit Application button (aka button1). canvas1 = tk.Canvas(root, width = 300, height = 300) Note that you can change the width and height of your GUI screen by modifying the numeric values for your canvas. You can then place items, such as buttons, on the canvas. (2) You’ll also need to create the Canvas, which will become your GUI screen. This package is used to create a Graphical User Interface (GUI) in Python: import tkinter as tk (1) Initially, you’ll need to import the tkinter package. Let’s now review the components used in the code. Tk.messagebox.showinfo('Return','You will now return to the application screen')īutton1 = tk.Button (root, text='Exit Application',command=ExitApplication,bg='brown',fg='white')Ĭanvas1.create_window(150, 150, window=button1) MsgBox = tk.messagebox.askquestion ('Exit Application','Are you sure you want to exit the application',icon = 'warning') ![]() import tkinter as tkĬanvas1 = tk.Canvas(root, width = 300, height = 300) In the next section, I’ll explain each component that was applied in the code. #Tkinter popup window with entry full#Here is the full code to create a yes/no message box in Python.
