pyqt5鼠标点击事件_pyqt5获取鼠标点击的控件?

在PyQt5中想要实现追踪鼠标的坐标，并实现实时打印出来，需要开启鼠标追踪功能。如果想要界面中的所有组件，或者QDialog弹窗获取坐标点，那么每个组件都需要做如下设置

setMouseTracking(True)

注意：

如果重写了一个组件，想要组件获取鼠标坐标，且组件为弹窗式，这样需要在重写的组件中加上

mouseMoveEvent方法

from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QDialog
# 自定义QDialog组件，增加最大化最小化按钮
class My_Dialog(QDialog):
    def __init__(self, parent=None):
        super(My_Dialog, self).__init__(parent)
        self.setupUi()

    def setupUi(self):
        # self.setWindowFlags(Qt.framelessWindowHint)  # 去除边框
        self.setWindowFlags(Qt.Dialog | Qt.WindowMinMaxButtonsHint | Qt.WindowCloseButtonHint)  # 最大化最小化关闭按钮
        pass

    def mouseMoveEvent(self, QMouseEvent):  # 5
        x = QMouseEvent.x()
        y = QMouseEvent.y()
        global_x = QMouseEvent.globalX()
        global_y = QMouseEvent.globalY()

        print(x, y)

下面是一个例子，主窗口有几个组件，外加一个按钮，点击按钮会弹出QDialog窗口，重写了QDialog窗口，鼠标在QDialog窗口滑动时，也会触发打印坐标点的事件

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(561, 335)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.horizontalLayout = QtWidgets.QHBoxLayout(self.centralwidget)
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.mdiArea = QtWidgets.QMdiArea(self.centralwidget)
        self.mdiArea.setObjectName("mdiArea")
        self.horizontalLayout.addWidget(self.mdiArea)
        self.start_btn = QtWidgets.QPushButton(self.centralwidget)
        self.start_btn.setObjectName("start_btn")
        self.horizontalLayout.addWidget(self.start_btn)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 561, 22))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
        self.dockWidget_2 = QtWidgets.QDockWidget(MainWindow)
        self.dockWidget_2.setObjectName("dockWidget_2")
        self.dockWidgetContents_2 = QtWidgets.QWidget()
        self.dockWidgetContents_2.setObjectName("dockWidgetContents_2")
        self.dockWidget_2.setWidget(self.dockWidgetContents_2)
        MainWindow.addDockWidget(QtCore.Qt.DockWidgetArea(1), self.dockWidget_2)

        self.retranslateUi(MainWindow)
        QtCore.QmetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.start_btn.setText(_translate("MainWindow", "start"))
