QInputDialog, Set the font for QPlainTextEdit and QLabel separately
I want to set font size for this QPlainTextEdit only (not change QLabel font size), but no way.

import sys

from PySide2.QtGui import QFont
from PySide2.QtWidgets import QInputDialog, QApplication, QWidget


class MyInputDialog(QInputDialog):
    def __init__(self, parent, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        self.setOption(QInputDialog.UsePlainTextEditForTextInput)
        self.setWindowTitle('title')
        self.setLabelText("label\nlabel")
        self.setTextValue('I want to set font size for this QPlainTextEdit only, but no way.')
        self.resize(600, 240)
        font = QFont()
        font.setFamily("Consolas")
        # font.setPointSize(10) #
        self.setFont(font)
        self.setStyleSheet("""QPlainTextEdit {
  font-size: 20;
}""")


class Widget(QWidget):
    def __init__(self, parent=None, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        dialog = MyInputDialog(self)
        ok = dialog.exec()
        sys.exit(0)


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

The only way is to use a custom widget?

if name == 'main':
app = QApplication(sys.argv)
w = Widget()
sys.exit(app.exec_())

Font size without unit, add it.
font-size: 20pt;

In C++ I would try to call something like findChildren<QTextEdit*>() on the dialog. I am not sure how this templated call would translate to Python, though. Then you could manipulate the text edit however you want.

Otherwise the complete implementation of a new dialog suggested by @Denni-0 is the way to go.

@Denni-0 @SimonSchroeder Very helpful, thanks. 🤣
