Python GUI GridLayout with Pyside2 | Qt For Python

In this Python GUI Development article iam going to talk about creating GridLayout with Pyside2 (Qt For Python), basically we are using QGridLayout class for this article. also you can watch more articles on Python GUI Development with Pyside2 in the below links.

What is GridLayout ?

The QGridLayout class lays out widgets in a grid.

QGridLayout takes the space made available to it (by its parent layout or by the parentWidget()), divides it up into rows and columns, and puts each widget it manages into the correct cell.

Columns and rows behave identically; we will discuss columns, but there are equivalent functions for rows.

Each column has a minimum width and a stretch factor. The minimum width is the greatest of that set using setColumnMinimumWidth() and the minimum width of each widget in that column. The stretch factor is set using setColumnStretch() and determines how much of the available space the column will get over and above its necessary minimum.

Normally, each managed widget or layout is put into a cell of its own using addWidget(). It is also possible for a widget to occupy multiple cells using the row and column spanning overloads of addItem() and addWidget(). If you do this, QGridLayout will guess how to distribute the size over the columns/rows (based on the stretch factors).

 

 

So now this is the complete code for Python GUI GridLayout with Pyside2 | Qt For Python

 

 

 

OK in the above code  first we have imported our classes from Pyside2 library

 

 

And this is our main window class that inherits from QWidget, and we are going to add a few requirements for our window in this class like title, width, height and also we are calling our two methods in this class, the methods are setIcon() and createGridLayout() methods . after that we create our QVBoxLayout in our class. and at the end of this class we show our window by calling self.show() method.

 

 

Also this method is for setting our window icon

 

 

So now this is the creation of our GridLayout, in the first we are going to create a QGroupBox also we have set the font of our QGroupBox, after that we create the object of our QGridLayout(), basically we are going to add six QPushButton in our QGridLayout. also make sure that you have some icons in your working directory for the Buttons. and at the end we set our QGroupBox to our QGridLayout by using self.groupBox.setLayout(gridLayout).

 

 

Also every Pyside2 application must create an application object. The sys.argv parameter is a list of arguments from a command line.

Python scripts can be run from the shell. It is a way how we can control the startup of our scripts.

 

 

Finally, we enter the mainloop of the application. The event handling starts from this point. The mainloop receives events from the window system and dispatches them to the application widgets. The mainloop ends if we call the exit() method or the main widget is destroyed. The sys.exit() method ensures a clean exit. The environment will be informed how the application ended.

The exec_() method has an underscore. It is because the exec is a Python keyword. And thus, exec_() was used instead

 

 

So now run the complete code and this will be the result
