Widget overlap eachother in GridLayout

Question

I am trying to create a simple Program using GridLayout, all the widgets inside the QWidget window do show up and scale properly however the LineEdit overlaps the Title Label of the window.

from PySide2 import QtWidgets, QtCore, QtGui
import sys

class SimGrid(QtWidgets.QWidget):
    def __init__(self):
        super(SimGrid, self).__init__()
        self.setWindowTitle("My attempt at Grid Layout")
        grid = QtWidgets.QGridLayout()
        self.setLayout(grid)

        title = QtWidgets.QLabel("This is some big sample text to fill up")
        title.setAlignment(QtCore.Qt.AlignHCenter)
        text_edit = QtWidgets.QTextEdit()
        success = QtWidgets.QPushButton("Success", self)
        cancel = QtWidgets.QPushButton("Cancel", self)

        grid.addWidget(title, 0, 0, 0, 0)
        grid.addWidget(text_edit, 1, 0, 1, 2)
        grid.addWidget(success, 4, 0)
        grid.addWidget(cancel, 4, 1)
        self.show()

According to the docs you are using the following method:

void QGridLayout::addWidget(QWidget *widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::Alignment alignment = ...)

The third and fourth parameters indicate the quantities and columns that will occupy, respectively, in your case the title will occupy 0 rows and 0 columns which is incorrect.

Using these criteria what you want is the following:

import sys
from PySide2 import QtWidgets, QtCore, QtGui


class SimGrid(QtWidgets.QWidget):
    def __init__(self):
        super(SimGrid, self).__init__()
        self.setWindowTitle("My attempt at Grid Layout")
        grid = QtWidgets.QGridLayout()
        self.setLayout(grid)

        title = QtWidgets.QLabel("This is some big sample text to fill up")
        title.setAlignment(QtCore.Qt.AlignHCenter)
        text_edit = QtWidgets.QTextEdit()
        success = QtWidgets.QPushButton("Success", self)
        cancel = QtWidgets.QPushButton("Cancel", self)

        grid.addWidget(title, 0, 0, 1, 2)
        grid.addWidget(text_edit, 1, 0, 1, 2)
        grid.addWidget(success,2, 0, 1, 1)
        grid.addWidget(cancel,  2, 1, 1, 1)
        self.show()


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    w = SimGrid()
    w.show()
    sys.exit(app.exec_())

that worked, can you tell me why one of the buttons is bigger than the other? And the AlignCenter is not working either. — Sahil, Jul 20 '18 at 15:53
