pyqt grid layout

PyQt5 supports a grid layout, which is named QGridLayout. Widgets can be added to a grid in both the horizontal and vertical direction. An example of a grid layout with widgets is shown below:

PyQt5 grid layout example:
The example below creates the grid:


import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QHBoxLayout, QGroupBox, QDialog, QVBoxLayout, QGridLayout
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot

class App(QDialog):

def __init__(self):
super().__init__()
self.title = 'PyQt5 layout - pythonspot.com'
self.left = 10
self.top = 10
self.width = 320
self.height = 100
self.initUI()

def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)

self.createGridLayout()

windowLayout = QVBoxLayout()
windowLayout.addWidget(self.horizontalGroupBox)
self.setLayout(windowLayout)

self.show()

def createGridLayout(self):
self.horizontalGroupBox = QGroupBox("Grid")
layout = QGridLayout()
layout.setColumnStretch(1, 4)
layout.setColumnStretch(2, 4)

layout.addWidget(QPushButton('1'),0,0)
layout.addWidget(QPushButton('2'),0,1)
layout.addWidget(QPushButton('3'),0,2)
layout.addWidget(QPushButton('4'),1,0)
layout.addWidget(QPushButton('5'),1,1)
layout.addWidget(QPushButton('6'),1,2)
layout.addWidget(QPushButton('7'),2,0)
layout.addWidget(QPushButton('8'),2,1)
layout.addWidget(QPushButton('9'),2,2)

self.horizontalGroupBox.setLayout(layout)

if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())

Explanation

We import the gridlayout and others with:


from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QHBoxLayout, QGroupBox, QDialog, QVBoxLayout, QGridLayout

In the method createGridLayout() we create the grid with a title and set the size.


def createGridLayout(self):
self.horizontalGroupBox = QGroupBox("Grid")
layout = QGridLayout()
layout.setColumnStretch(1, 4)
layout.setColumnStretch(2, 4)

Widgets are added using


layout.addWidget(Widget,X,Y)

Finally we set the layout.

Several buttons are added to the grid. To add a button click action you need a pyqtslot.

If you are new to programming Python PyQt, I highly recommend this book.
