Creating PyQt Layouts for GUI Applications (Overview)

Creating PyQt Layouts for GUI Applications Christian Koch 02:37

PyQt’s layout managers provide a user-friendly and productive way of arranging graphical components, or widgets, on a GUI. Laying out widgets properly will make your GUI applications look polished and professional. Learning to do so efficiently and effectively is a fundamental skill for you to get up and running with GUI application development using Python and PyQt.

In this course, you’ll learn:

What the benefits are of using PyQt’s layout managers
How to programmatically lay out widgets on a GUI using PyQt’s layout managers
How to select the right layout manager for your GUI application
How to lay out widgets in main window–based and dialog-based applications

For a better understanding of how to use layout managers, some previous knowledge of how to create PyQt GUI applications and how to work with PyQt widgets would be helpful.

00:00 Hello there! In this course, we are going to create flexible GUIs in PyQt5. Specifically, here’s what we are going to make. We are going to create some GUIs that scale in the horizontal axis, some that scale on the vertical axis, some that scale on both axes, and we are also going to make some GUIs that have tabs and entire different pages.

00:22 All of this can be achieved very easily because all we need to learn about is the PyQt layout manager. This is what we are going to focus on in this course.

00:32 This one allows us to place a widget on a GUI and to make it responsive, and this is going to be the main thing we are going to learn about. Besides that, we are going to talk about how to select specific layouts for specific purposes and generally, we are going to talk about how to create flexible GUIs in a presentable manner. All of this should be fairly straightforward, although I would recommend that you already know the basics of PyQt.

00:59 Now, this doesn’t have to be much. The minimum you should know is how to create a window in PyQt and at least know what widgets are. Although later on for one video, we are also going to use signals and slots, although we are only going to use it for the pages later on.

01:16 This comes quite late in this course, so you could follow most of the lessons without knowing about signals. But generally, most of the concepts are fairly simple, so if you know the basics of PyQt, this should be fairly straightforward.

01:29 I am using the latest version of PyQt5, which at the moment is 5.15.2. I assume that you already have PyQt installed yourself, either on the system or in a virtual environment that you know how to use. Now, if none of that made sense and you are just starting out with PyQt, check out the PyQt learning path.
