[PyQt] QGridLayout, QProgressBar bar fills widgets shrink

[deanhystad]

I don't see any problem with your original code. I just added the main window and frame, and some code to change the progress bar when you type in the QEditText widget. I don't see any lahout changes.

from PySide6.QtWidgets import QApplication, QMainWindow, QFrame, QLineEdit, QProgressBar, QLabel, QGridLayout, QTextEdit
from PySide6.QtCore import QTimer

class Window(QMainWindow):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        frame = QFrame()
        self.setCentralWidget(frame)
        layout = QGridLayout(frame)
        header = ['To:', 'CC:', 'BCC:', 'Subject:']
        edits = [QLineEdit(), QLineEdit(), QLineEdit(), QLineEdit()]
        for i, (lab, lin) in enumerate(zip(header, edits)):
            layout.addWidget(QLabel(lab), i, 0)
            layout.addWidget(lin, i, 1, 1, 5)

        self.edit = QTextEdit()
        self.prog = QProgressBar()
        layout.addWidget(self.edit, 4, 0, 1, 6)
        layout.addWidget(self.prog, 5, 1)

        timer = QTimer(self)
        timer.timeout.connect(self.update_progress)
        timer.start(100)

    def update_progress(self):
        self.prog.setValue(len(self.edit.toPlainText()))


app = QApplication()
window = Window()
window.show()
app.exec()
