How to open a new window by the user pressing a button in a tkinter GUI?
Tkinter creates a default window (i.e., master or root window) for every application. In tkinter, we can create a Popup window or a child window by defining a Toplevel(master) constructor. This will allow the tkinter application to create another window which can be resized dynamically by defining its size property.
Example
In this example, we have created a button widget that will open the new window with a text label.
#Import tkinter library from tkinter import * from tkinter import ttk #Create an instance of tkinter frame or window win= Tk() #Set the geometry of tkinter frame win.geometry("750x250") #Define a new function to open the window def open_win(): new= Toplevel(win) new.geometry("750x250") new.title("New Window") #Create a Label in New window Label(new, text="Hey, Howdy?", font=('Helvetica 17 bold')).pack(pady=30) #Create a label Label(win, text= "Click the below button to Open a New Window", font= ('Helvetica 17 bold')).pack(pady=30) #Create a button to open a New Window ttk.Button(win, text="Open", command=open_win).pack() win.mainloop()
Output
Running the above code will display a window that contains a button widget. When we click the button, it will open a new Window.
Now, click the "Open" button to open a new Window.
