Line spacing in QTextEdit

[Devik]

Is it possible to make line spacing for QTextEdit?

Hi,

You are looking for the QTextBlockFormat class.

I found the setLineHeight method, but I don't understand how I can apply it to my TextEdit. Can you show me an example?

What am I doing wrong?

If this is your actual code you should get NameError: name 'lineSpacing' is not defined error.
If this is not your actual code then we don't know what your code really is.
Please only post code which is actually copied & pasted from what you are really testing!

The following works fine for me:

import sys
from PySide2 import QtWidgets, QtGui

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    textEdit = QtWidgets.QTextEdit()
    textEdit.show()
   
    textEdit.setText('Sample text Sample text Sample text Sample text Sample text Sample text Sample text '
                     'Sample text Sample text Sample text Sample text Sample text Sample text Sample text')
    bf = textEdit.textCursor().blockFormat()
    bf.setLineHeight(50, QtGui.QTextBlockFormat.LineDistanceHeight)
#    bf.setLineHeight(lineSpacing, QtWidgets.QTextBlockFormat.LineDistanceHeight)
    textEdit.textCursor().setBlockFormat(bf)
        
    sys.exit(app.exec_())

Tested under Ubuntu 22.04, PySide2, Qt5.15. That's all I have.
