Перетаскивание окна за верхнюю область FramelessWindowHint окна

Question

Подскажите, пожалуйста, как сделать так, чтобы окно перетаскивалась только за верхнюю область (self.label)?

В представленном коде , окно перетаскивается при зажатии кнопки мыши в любой области окна.

Вам нужно создать виджет верхней области и определить в ней все что вам надо.

Выглядит это примерно так:

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


class MyBar(QWidget):
    def __init__(self, parent):
        super(MyBar, self).__init__()
        self.parent = parent

        self.layout = QHBoxLayout(self)
        self.layout.setContentsMargins(0, 0, 10, 0)
        self.title = QLabel("My Title Bar")

        btn_size = 16 

        self.btn_close = QtWidgets.QPushButton()
        self.btn_close.setStyleSheet("""
            border-radius: 7px;
            background-color: rgb(255, 0, 4);
        """)
        self.btn_close.setText("")
        self.btn_close.clicked.connect(self.btn_close_clicked)
        self.btn_close.setFixedSize(btn_size, btn_size)
        
        
        self.btn_min = QtWidgets.QPushButton()
        self.btn_min.setStyleSheet("""
            background-color: rgb(255, 183, 0);
            border-radius: 7px;
        """)
        self.btn_min.clicked.connect(self.btn_min_clicked)
        self.btn_min.setFixedSize(btn_size, btn_size)

        self.title.setFixedHeight(32)
        self.title.setAlignment(Qt.AlignCenter)
        
        self.layout.addWidget(self.title)
        self.layout.addWidget(self.btn_min)

        self.title.setStyleSheet("""

                                self.parent.width(),

    def btn_min_clicked(self):
        self.parent.showMinimized()

        self.horizontalLayout.setContentsMargins(0, 0, 0, 0)
        self.horizontalLayout.setSpacing(0)        

        self.page_1 = QtWidgets.QWidget()
        self.verticalLayout = QtWidgets.QVBoxLayout(self.page_1)
        self.verticalLayout.setContentsMargins(0, 0, 0, 0)
