To do so, you can pass the font parameter like this: lbl = Label(window, text="Hello", font=("Arial Bold", 50)) ![]() ![]() You can set the label font so you can make it bigger and maybe bold. Without calling the grid function for the label, it won’t show up. So the complete code will be like this: from tkinter import * Then we will set its position on the form using the grid function and give it the location like this: lbl.grid(column=0, row=0) To add a label to our previous example, we will create a label using the label class like this: lbl = Label(window, text="Hello") If you forget to call the mainloop function, nothing will appear to the user. The last line which calls the mainloop function, this function calls the endless loop of the window, so the window will wait for any user interaction till we close it. Specify file types (filter file extensions)įirst, we will import Tkinter package and create a window and set its title: from tkinter import *.Add a filedialog (file & directory chooser).Add a ScrolledText widget (Tkinter textarea).Get radio button value (selected radio button).Add a Checkbutton widget (Tkinter checkbox).Get input using Entry class (Tkinter textbox).Change button foreground and background colors.Pretty neat, huh? Obviously there is much more to cover. The above code put together should spawn you a window that looks like: app = Window(root)įinally, show it and begin the mainloop. Here, that would be the only window, but you can later have windows within windows. The above is really all we need to do to get a window instance started. Then we define the settings upon initialization. Frame is a class from the tkinter module. Here, we are creating our class, Window, and inheriting from the Frame class. Simple enough, just import everything from tkinter. Let's walk through each step to making a tkinter window: Python is not very popularly used for this purpose, but it is more than capable of doing it. We get a window that we can resize, minimize, maximize, and close! The tkinter module's purpose is to generate GUIs. Here, we show how simple it is to create a very basic window in just 8 lines. The tkinter module is a wrapper around tk, which is a wrapper around tcl, which is what is used to create windows and graphical user interfaces. ![]() In this video, we begin discussion of the tkinter module. ![]()
