This tutorial is written in PyQt4, but there is a newer version, PyQt5, that you can use. There are some differences, and kenwaldek has ported this series code, by individual tutorial code, to PyQt5 here. First, we need to go ahead and get PyQT4. To do this, if you are on Windows, head to: river bank computing. We will use sys shortly just in case we want our application to be able to accept command line arguments, but also later on to ensure a nice, clean, close of the application when we want to exit.

All of the PyQT sections are:. We are creating a QApplication object, and saving it to "app. For more information on this, see our sys module with Python tutorial. Next, we define our window. Now this can sometimes be a little confusing. With GUIs, you generally have what is referred to as the "application," or the "frame," and then you have the "window" or the actual "gui" part. The frame is just the encapsulation of the window, literally on the screen, as well as in the background.

You will probably better understand this as time goes on, but think of "application" as literally the border that goes around your window. Here, we can modify the window a bit. Keep in mind, that applications and their windows are created in memory first, then they are brought to the user's screen last. This is the same process that you see done with other forms of Graphics in programming, like games with PyGame, or graphing with Matplotlib.

The reason for this is graphical rendering is cumbersome, and it would be rather inefficient to continuously be making edits and refreshing to the user's screen for each element. So, when we modify the window like this, it is not like the window will pop up full screen, and then change shape moments later. The screen has not yet been shown to the user, we're just building it in the memory. QWidget class. It is taking four parameters from us. First you have the window's starting x coordinate, then you have the starting y coordinate 0 and 0.

Next, you have the window's dimensions, which are and , meaning pixels wide and tall. So now you have a very basic GUI application. Now that you see the fundamentals of how a GUI with QT works, we're going to talk about how to lay the foundation for a full application next.
