PyQt5 Tutorial – Creating Your Own GUI Applications With PyQt5

Learning to create your own GUI applications using PyQt5 is not as difficult as it sounds. It requires only a few basic concepts and can be learned quickly. There are plenty of tutorials available online that will guide you through the process of creating a custom app. You can also learn about the different widget types available with PyQt5, including QTableWidget, QInputDialog, QMenuBar, and QScrollBar.

QTableWidget

QTableWidget is one of the most popular widgets used to display data. It creates a table with rows and columns of data. Each cell contains individual values, which can be edited or deleted. However, changes to the cells will not be saved to the database. To create a QTableWidget, you first need to create an object with the QTableWidget class.

QInputDialog

A QInputDialog is a dialogue that can be used to capture input. It has several fields and properties and can be used to display a user’s data. The tutorial will go over how to use QInputDialog and build a simple application.

QMenuBar

The QMenuBar class displays a horizontal menu bar at the top of your window. It can contain strings and QAction objects. You can also include buttons and other widgets in your menu bar. QTab separates the contents of a window into two pages – a tab bar and a tab page.

QScrollBar

To create a scroll bar, use the QScrollArea class. It can hold any widget but is best used for multiple data widgets on a dashboard. It is also less appropriate for controlling widgets. QScrollArea is derived from Qt4 and can be found in the QtGui class. It is used in the Image Viewer example in this tutorial.

QSplitter

QSplitter is a very handy tool in many different applications. It lets you control the size of your windows and saves your preferences for future use. Unlike other window managers, QSplitter is not dependent on your local settings. For example, you can set the size of your splitters and maintain them even when you switch to a different computer. You can create a splitter with the exact size and position you need using a simple code snippet.

QHBoxLayout

You can create GUI applications in Python using QHBoxLayout. This class allows you to place multiple elements in a row. You can place a QDialog object in this container and use it as a dialogue box when you click a button.

QVBoxLayout

QVBoxLayout is a top-level layout that can be used to display a variety of widgets vertically. This is equivalent to red, green, and blue layouts, but it can handle more than one cell simultaneously. To create a QVBoxLayout, add it to your window and then use its constructor to add widgets to the layout.

QPushButton

The QPushButton class provides you with an easy way to create buttons in PyQT5. The QPushButton class enables you to create one or more buttons, and you can also set the button text and icon. You can also handle the click events for these buttons.
