The following code runs after creating a new environment and pip install PyQt5:
from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QLabel, QLineEdit, QPushButton
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.layout = QGridLayout()
self.here_is_id = QLabel("Here is system id: ")
self.layout.addWidget(self.here_is_id, 0,0)
self.id_label = QLabel("3139668d-b0d1-4b84-9080-52474790b56c")
self.layout.addWidget(self.id_label, 0,1)
self.label = QLabel("Enter password: ")
self.layout.addWidget(self.label, 1,0)
self.edit = QLineEdit()
self.layout.addWidget(self.edit, 1, 1)
self.confirm_button = QPushButton('Confirm')
self.layout.addWidget(self.confirm_button, 2, 0)
self.cancel_button = QPushButton('Cancel')
self.layout.addWidget(self.cancel_button, 2, 1)
self.setLayout(self.layout)
self.resize(450,300)
if __name__ == "__main__":
import sys
system_app = QApplication(sys.argv)
main = MainWindow()
main.show()
system_app.exec()
It gives:
The two problems are:
- It is not evenly spaced.
- The cancel button is a lot longer than confirm button.
Question: how do I resolve both issue without changing the size of the widget? That is, the space between each row will be even and the two buttons have the same size. The length of QLineEdit should not be changed.
My attempt is to use commands like self.layout.setColumnStretch and self.layout.setSpacing. However, none of the command actually changes the widget. I am stuck on how to proceed.
