PyQt5 grid layout


PyQt5 supports a grid layout, which is named QGridLayout.

pyqt-grid-layout

PyQt5 grid layout example:

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.
