QFormLayout() set window size - which is the best solution?

PythonQTMarlem

Hello,

here my code:

import sys
from PyQt6.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, \
    QPushButton, QFormLayout, QLineEdit

class Window(QWidget):
    define __init__(self):
        super().__init__()
        self.UI()

    define UI(self):
        self.setWindowTitle("QFormLayout()")
        self.lname = QLabel("&Name:")
        self.nameLineEdit = QLineEdit()
        self.lmail = QLabel("&Email:")
        self.emailLineEdit = QLineEdit()
        self.lname.setBuddy(self.nameLineEdit)
        self.lmail.setBuddy(self.emailLineEdit)
        self.btn_programm_beenden = QPushButton("En&de", self)
        self.btn_terminate_program.setDefault(True)
        self.btn_programm_beenden.clicked.connect( self.programm_beeden)

        formLayout = QFormLayout()
        #Several control elements can be placed in a row
        #to be included
        formLayout.addRow(self.lname,self.nameLineEdit)
        formLayout.addRow(self.lmail,self.emailLineEdit)
        formLayout.addRow(self.btn_terminate_program)
        self.setLayout(formLayout)

    def program_finished(self):
        QApplication.instance().quit()


app = QApplication(sys.argv)
window = Window()
window.show()
sys.exit(app.exec())

I know that you can set the window size with setGeometry. Disadvantage: The use of coordinates could cause problems in terms of platform independence.

Then today I found out that you can set the window size with setFixedHeight and setFixedWidth. The charm of this solution is that the window is centered. Disadvantage: The user cannot change the fixed size with the computer mouse.

I'm looking for a solution
which is platform independent
The window is centered
The user can adjust the window size.

What can you recommend me?

Hi,

Do you mean you would like for your application window to be shown centered on whatever screen the user starts your application on ?

If so you should take a look at the QScreen class.
