i use scintillaeditbase.h instead of textarea etc..
So i want to show line number to use scintillaeditbase.h
is there any options?

Hi,

Do you mean https://qscintilla.com/ ?

gnoowami

@SGaist Yes i mean that!

SGaist

From a quick check, it looks like you need to set the STYLE_LINENUMBER from Scintilla.

@SGaist i know this option, but i dont know how to use this option.
I use scintillaeditbase.cpp and scintillaeditbase.h

I found a simpler way to do it, see the following:

import pathlib
import sys
from PyQt5.QtGui import QFont, QFontMetrics, QColor
from PyQt5.QtWidgets import QApplication
from PyQt5.Qsci import QsciScintilla, QsciLexerPython


class SimplePythonEditor(QsciScintilla):
    def __init__(self, parent=None):
        super().__init__(parent)

        # Set the default font
        font = QFont()
        font.setFamily("Courier")
        font.setFixedPitch(True)
        font.setPointSize(10)
        self.setFont(font)

        # Margin 0 is used for line numbers
        fontmetrics = QFontMetrics(font)
        self.setMarginsFont(font)
        self.setMarginWidth(0, fontmetrics.width("00000") + 6)
        self.setMarginLineNumbers(0, True)
        self.setMarginsBackgroundColor(QColor("#cccccc"))

        lexer = QsciLexerPython()
        lexer.setDefaultFont(font)
        self.setLexer(lexer)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    editor = SimplePythonEditor()
    editor.show()
    editor.setText(pathlib.Path(sys.argv[0]).read_text())
    sys.exit(app.exec())
