Doing a spell checker (using PyQt5 for the interface). I check the sentence entered in the editor and misspelled words, I highlight in red.

Tell me how to do what when you hover over such a word with the mouse, below popup text appeared with correct options? Here is a sample spell check code

import sys
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui, QtWidgets



class Example(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Hello")

        self.editTextArea = QtWidgets.QPlainTextEdit(self)
        self.editTextArea.setGeometry(QtCore.QRect(10, 10, 250, 250))
        self.editTextArea.setObjectName("editTextArea")

        variants = ['hello', 'hello1', 'hello2']
        word = 'Hallo'
        text =  "The word %s is not spelled correctly! Variants in the variants array and need to be displayed when hovering over the red word of the mouse " % word
        text = text.replace(word, '<span style="text-decoration: underline; color: red">' + word + '</span>')
        self.editTextArea.appendHtml(text)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    form = Example()
    form.show()
    app.exec()

I would like that when you hover the mouse over the red word, a window pops up with the correct options from the variants array, and when you click on one of the correct words, the wrong one is replaced.

    Unfortunately, while your question seems reasonable and technically correctly asks just a single question, it actually raises more than one as what you want to achieve is *not* simple: Qt provides the [QSyntaxHighlighter](https://doc.qt.io/qt-5/qsyntaxhighlighter.html) class that can be used for your needs, but it requires a complete implementation in this case, as you requirement is to highlight a word that does *not* match correct ones, so you must provide a vocabulary of *all* valid words; after that you'll need to work with the underlying QTextDocument in order to allow the menu feature. – musicamante Feb 21 '21 at 12:16

    Since you're a beginner, you need to do some research and get experienced before being able to *correctly* do what you do, so I suggest you to start by looking for examples and questions about spell checking and QSyntaxHighlighter (such as [this](https://stackoverflow.com/questions/36343172/pyqt4-spell-check-with-syntax-highlighter) or [this](https://stackoverflow.com/questions/8722061/pyqt-how-to-turn-on-off-spellchecking)). Finally, you should not use fixed geometries for child widgets, especially for QMainWindow: remove `setGeometry()` and use `self.setCentralWidget(self.editTextArea)`. – musicamante Feb 21 '21 at 12:20
