- [Instructor] Hi, and welcome to section one,GUI in Python.In this section, we are developing our first GUI in Python.We will create a working GUI applicationthat consists of labels, buttons, text boxes,combo boxes, check buttons in various statesas well as radio buttonsthat change the background color of the GUI.
Python GUI Widgets. You can add widgets into the window. Also note that there are a wide variety of widgets you can use from tkinter. But, as we cannot cover all of those widgets, we cover the basic and regularly used widgets in this Python GUI Tutorial. Those widgets are: Button; Canvas; CheckButton; RadioButton; Entry; Frame; Label; Listbox; Menu; MenuButton; Message; Scale. Python provides several different options for writing GUI based programs. These are listed below: Tkinter: It is the easiest among all to get started with. It is Python's standard GUI (Graphical User Interface) package. It is the most commonly used toolkit for GUI Programming in Python. Instructor Hi, and welcome to section one, GUI in Python. In this section, we are developing our first GUI in Python.

PySide – GUI- und Anwendungsentwicklung mit Python und Qt, on Python GUI development, which was published in 2012. Currently, he is getting crazy with embedded and open hardware platforms and is working on a modular game console based on open hardware. Joseph Rex is a full stack developer with a background in computer security. He has worked. Graphical User Interfaces (GUI) Graphical interfaces can be made using a module such as PyQt5, PyQt4, wxPython or Tk. PyQt5 is the most popular option for creating graphical apps with Python.
Be a concise, but not superficial, treatment on GUI programming. Part III contains information on the features of Python that allow you to accomplish big things with surprisingly little code. In preparing this book the Python documentation atwww.python.orgwas indispensable. This book was composed entirely in.
In this video, we're going to create our first GUI.Then, we'll prevent it from being resized.Python is a very powerful programming language.It ships with the built-in Tkinter module.In only a few lines of code, four to be precise,we can build our first Python GUI.To follow this video,a working Python development environment is a prerequisite.The IDLE GUI that ships with Python is enough to start.
IDLE was built using Tkinter.In this video, we'll be using Atom.Cool, let's jump right in.Here are the four lines of Python code requiredto create the resulting GUI.On the first line, we import the built-in Tkinter moduleand alias it as tk to simplify our Python code.In line two, we create an instance of the tk classby calling its constructor, the parenthesesappended to Tk, turn the class into an instance.
We are using the alias tkso we don't have to use the longer word Tkinter.We are assigning the class instanceto a variable named win, short for window.As Python is a dynamically-typed language,we did not have to declare this variablebefore assigning to it.And we did not have to give it a specific type.Python infers the type from the assignment of the statement.Python is a strongly-typed language,so every variable always has a type.
We just don't have to specify its type beforehandlike in other languages.This makes Python a very powerfuland productive language to program in.In line three, we use the instance variableof the class win to give our window a titlevia the title property.In line four, we start the windows event loopby calling the mainloop method on the class instance win.
Up to this point in our code,we created an instance and set one property,but the GUI will not be displayeduntil we start the main event loop.Okay, let's execute this code.The filename is FirstGUI.py.Here's our first ever GUI.Cool, isn't it?Please note that in this filewe used a minimum amount of Python codeto create our first GUI program.However, throughout this course,we will use object-oriented programmingwhen it makes sense.
Okay, let's now move on to preventing the GUIfrom being resized.How do we do that?Well, here's another file named NotResizable.py.This file extends the previous one.What is different then?Line four prevents the Python GUI from being resized.Running this code will result in a GUIsimilar to the one we created just now.Let's see the output.As you can see, the user can no longer resize it.
Also, notice how the maximum buttonin the toolbar of the window is grayed out.Why is this important?Because once we add widgets to our form,resizing can make our GUI look not as goodas we want it to be.We will add widgets to our GUI in the next videos.Resizable is a method of the tk class,and by passing in (0,0), we prevent the GUIfrom being resized.
If we pass other values, we hardcode the Xand Y startup size of the GUI,but that won't make it non-resizable.Nice, we created our first ever GUI in this video.In the next one, we'll add a label to our form.

Python provides various options for developing graphical user interfaces (GUIs). Most important are listed below.
There are many other interfaces available, which you can find them on the net.
Tkinter Programming
Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit.
Creating a GUI application using Tkinter is an easy task. All you need to do is perform the following steps −

This would create a following window −
Tkinter Widgets
Tkinter provides various controls, such as buttons, labels and text boxes used in a GUI application. These controls are commonly called widgets.

Geometry ManagementPython Gui Kivy Pdf
All Tkinter widgets have access to specific geometry management methods, which have the purpose of organizing widgets throughout the parent widget area. Tkinter exposes the following geometry manager classes: pack, grid, and place.
