PyQt5 - QGridLayout Class

A GridLayout class object presents with a grid of cells arranged in rows and columns. The class contains addWidget() method. Any widget can be added by specifying the number of rows and columns of the cell. Optionally, a spanning factor for row as well as column, if specified makes the widget wider or taller than one cell. Two overloads of addWidget() method are as follows −

A child layout object can also be added at any cell in the grid.

Example

The following code creates a grid layout of 16 push buttons arranged in a grid layout of 4 rows and 4 columns.

import sys 
from PyQt5.QtCore import * 
from PyQt5.QtGui import * 
from PyQt5.QtWidgets import *

def window():
   app = QApplication(sys.argv)
   win = QWidget()
   grid = QGridLayout()
	
   for i in range(1,5):
      for j in range(1,5):
         grid.addWidget(QPushButton("B"+str(i)+str(j)),i,j)
			
   win.setLayout(grid)
   win.setGeometry(100,100,200,100)
   win.setWindowTitle("PyQt")
   win.show()
   sys.exit(app.exec_())

if __name__ == '__main__':
   window()

The code uses two nested for loops for row and column numbers, denoted by variables i and j. They are converted to string to concatenate the caption of each push button to be added at i^th row and j^th column.

The above code produces the following output −
