[PYTHON 3.8] How to transfer found pyqt code to pyside2? [BEGINNER]

[JustPassingBy]

I would like to know what do I have to do in order to convert found pyqt code when I research stuff in google to pyside2 for my project? For example I want to add mousePressEvent to my project and connect it to QLineEdit so when I click QLineEdit it select all of my text with selectAll() but I don't know how to do that with signals and just adding mousePressEvent function inside parent class works only if you click on QWidget and won't work if you click on QLineEdit.

I am sorry if this is going to be a duplicate post but please share tips of what to do when you find pyqt code snippet that you want but your project is in pyside2.

Source of what I'm looking at right now and want: https://stackoverflow.com/questions/25560748/add-a-click-on-qlineedit
What I want is this code to pyside:

mousePressed = QtCore.pyqtProperty(QtGui.QMouseEvent)
self.tc.mousePressed[QtGui.QMouseEvent].connect(self.mousePressEvent)

Edit (doing this with eventFilter so I don't have to create QLineEdit subclass but the problem is the selectAll() is not selecting the text):

import sys
import os


from PySide2.QtWidgets import (QApplication, QWidget,
                               QPushButton, QLineEdit,
                               QFileDialog, QLabel,
                               QProgressBar, QCheckBox,
                               QMessageBox)
from PySide2.QtCore import QFile, QThread, Signal
from PySide2.QtUiTools import QUiLoader
from PySide2 import QtXml
from PySide2.QtWinExtras import QtWin
from PySide2 import QtGui
import Resource


class GUI(QWidget):
    def __init__(self):
        super(GUI, self).__init__()
        self.load_ui()
        self.setFixedSize(607, 154)
        ...
        self.downloadURL = self.findChild(QLineEdit, "lineEditURL")
        self.downloadURL.installEventFilter(self)
        ...

    def load_ui(self):
        loader = QUiLoader()
        path = os.path.join(os.path.dirname(__file__), "form.ui")
        ui_file = QFile(path)
        ui_file.open(QFile.ReadOnly)
        loader.load(ui_file, self)
        ui_file.close()
        
        ...

    def mousePressEvent(self, event):
        print("testing123")
        super(GUI, self).mousePressEvent(event)

    def eventFilter(self, obj, event):
        if event.type() == event.MouseButtonPress:
            self.downloadURL.selectAll()
            print("test")

        return super(GUI, self).eventFilter(obj, event)

...

if __name__ == "__main__":
    app = QApplication([])
    app.setWindowIcon(QtGui.QIcon(":/icon/window_icon.ico"))
    widget = GUI()
    widget.show()
    sys.exit(app.exec_())

Output:

test
test
testing123
test
testing123
test
testing123
testing123
testing123
test
testing123
test
testing123
test
test
test
testing123
test
test
test
test
test

It works but selectAll() doesn't work and I don't know what to do.

Hi,

In this case, you should let the mouseButtonPress do its job first and only then call selectAll on your QLineEdit.
