You can create a textbox using Tkinter Entry class like this: #Tkinter tutorial python pdfminer3k how to#In the previous Python GUI examples, we saw how to add simple widgets, now let’s try getting the user input using Tkinter Entry class (Tkinter textbox). Note that, we typed clicked only not clicked() with parentheses.ītn = Button(window, text="Click Me", command=clicked)Īnd when we click the button, the result as expected:Ĭool!! Get input using Entry class (Tkinter textbox) Then we will wire it with the button by specifying the function like this:ītn = Button(window, text= “Click Me”, command=clicked) Lbl.configure(text="Button was clicked !!") Now, if you tried to click on the button, nothing happens because the click event of the button isn’t written yet.įirst, we will write the function that we need to execute when the button is clicked: You can change foreground for a button or any other widget using fg property.Īlso, you can change the background color for any widget using bg property.ītn = Button(window, text="Click Me", bg="orange", fg="red") Change button foreground and background colors ![]() If you forget and place the button on the same column which is 0, it will show the button only, since the button will be on the top of the label. Note that we place the button on the second column of the window which is 1. ![]() Let’s start by adding the button to the window, the button is created and added to the window the same as the label: Let’s try adding more GUI widgets like buttons and see how to handle button click event. The above line sets the window width to 350 pixels and the height to 200 pixels. We can set the default window size using geometry function like this: Great, but the window is so small, we can even see the title, what about setting the window size? Setting window size Note that the font parameter can be passed to any widget to change its font not labels only. Lbl = Label(window, text="Hello", font=("Arial Bold", 50)) To do so, you can pass the font parameter like this: 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. Then we will set its position on the form using the grid function and give it the location like this: To add a label to our previous example, we will create a label using the label class like this: If you forget to call the mainloop function, nothing will appear to the user. The last line which calls mainloop function, this function calls the endless loop of the window, so the window will wait for any user interaction till we close it. We will start by creating a window then we will learn how to add widgets such as buttons, combo boxes, etc, then we will play with their properties, so let’s get started.įirst, we will import Tkinter package and create a window and set its title: I assume that you a little background about Python basics to help you understand what we are doing. #Tkinter tutorial python pdfminer3k code#Sounds Cool!! We will use Python 3.6, so if you are using Python 2.x, it’s strongly recommended to switch to Python 3.x unless you know the language changes so you can adjust the code to run without errors. If you already have installed Python, you may use IDLE which is the integrated IDE that is shipped with Python, this IDE is written using Tkinter. Tkinter package is a very powerful package. #Tkinter tutorial python pdfminer3k install#Tkinter package is shipped with Python as a standard package, so we don’t need to install anything to use it. ![]() In this tutorial, we will learn how to develop graphical user interfaces by writing some Python GUI examples using Tkinter package. ![]()
