MousePressEvent在QPushbutton上不起作用

如何解决MousePressEvent在QPushbutton上不起作用

所以在我的qtgui中，我想知道何时有人单击（在任何QObject或窗口上）， 因此，我正在使用MousePressEvent。 但是，当我单击QPushbuttons时，该事件无法识别

我的代码有一个简单的版本

from PyQt5 import QtCore,QtGui,QtWidgets
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import os
from PyQt5.QtWidgets import QMainWindow

class Ui_MainWindow(QMainWindow):
    def __init__(self):
        super(Ui_MainWindow,self).__init__()

    def setupUi(self):
        self.setObjectName("MainWindow")
        self.resize(1920,1080)
        self.setStyleSheet("\n"
"")
        self.centralwidget = QtWidgets.QWidget(self)
        #self.centralwidget.setStyleSheet("#centralwidget{background-image: url(:/images/assets/back1.jpg);}")
        
        self.centralwidget.setObjectName("centralwidget")
        self.timer = 5000
        
        self.gridLayout_3 = QtWidgets.QGridLayout(self.centralwidget)
        self.gridLayout_3.setObjectName("gridLayout_3")

        self.but1 = QtWidgets.QPushButton(self.centralwidget)
        self.but1.setGeometry(QtCore.QRect(1500,500,301,51))
        self.but1.setMouseTracking(True)
        self.but1.setStyleSheet("QPushButton{\n"
                "border-style: outset;""\n"
                " border-radius: 10px;"
                "border-width: 2px;"
                "border-color: gray;"
                "font: 18pt \"Adobe Pi Std\";\n"
                "color: rgb(255,255,255);}\n"
                "QPushButton:pressed { border-style : inset; border-color:black}")
        self.but1.setObjectName("but1")
        self.but1.clicked.connect(lambda : self.addtimer())
        self.setCentralWidget(self.centralwidget)
        self.retranslateUi()
        QtCore.QMetaObject.connectSlotsByName(self)


  def mousePressEvent(self,event):
        #super(Ui_MainWindow,self).mousePressEvent(event) i tried this but change nothing
        print("Clicked")

  def addtimer(self):
       self.timer+=5000
       print(self.timer)

def retranslateUi(self):
        _translate = QtCore.QCoreApplication.translate
        self.setWindowTitle(_translate("MainWindow","MainWindow"))
        self.but1.setText(_translate("MainWindow","Explore!"))



if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    
    ui = Ui_MainWindow()
    ui.setupUi()
    ui.show()
    sys.exit(app.exec_())

我坚信此问题是由继承力不佳引起的，但我不知道该如何解决。

如果您想知道为什么我想知道何时有人单击，那么主要目的是设置一个Qtimer，如果在x时间后没有单击发生，它将关闭窗口

预先感谢

解决方法

您需要做的是确定您要检查的鼠标事件类型，然后转到pyqt5文档并搜索执行该操作的事件（这就是我所做的），这只是对检测该事件的逻辑进行编码。

#Below your other self.but1... u add this one to call the function each time u click
self.but1.clicked.connect(lambda: self.mousePressEvent(QMouseEvent.MouseButtonPress))

def mousePressEvent(self,event):
    #Here you check if the event u receive its the one you want to track
    if event == QMouseEvent.MouseButtonPress:
        print("Clicked")

希望此解决方案对您有所帮助。
