PyQt5中按钮长按指定时间后松开触发(鼠标事件)_pyqt 鼠标按下

背景：为了节约人力测试成本，模拟鼠标长按后松开，整理了这个简单的小demo

1、关键方法

实例鼠标按下事件

QMouseEvent(QEvent.MouseButtonPress,  self.p_pos, Qt.MouseButton.LeftButton,  Qt.MouseButton.LeftButton, Qt.NoModifier)
1

实例鼠标松开事件

QMouseEvent(QEvent.MouseButtonRelease,  self.p_pos, Qt.MouseButton.LeftButton,  Qt.MouseButton.LeftButton, Qt.NoModifier)
1

发送鼠标事件

QCoreApplication.sendEvent(self.tb, event)
1

• 参数1: 接受对象
• 参数2: 鼠标事件

2、测试代码

import os
import sys
from PyQt5.Qt import *


class Widget(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.resize(900, 600)

        self.p_pos = QPoint(0, 0)

        self.tb = QToolButton(self)
        self.tb.move(100, 200)
        self.tb.setAutoRepeat(True)
        self.tb.setText("测试")
        self.tb.clicked.connect(self.click_slot)

        t = QTimer(self)
        t.timeout.connect(self.timer_slot)
        t.start(4000)

    def timer_slot(self):
        print("timer_slot触发")

        # 1、按钮默认点击
        # self.tb.click()

        # 2、按钮模拟触发
        self.custom_press()

    def custom_press(self):
        print("鼠标按下")
        event = QMouseEvent(QEvent.MouseButtonPress,  self.p_pos, Qt.MouseButton.LeftButton,  Qt.MouseButton.LeftButton, Qt.NoModifier)
        QCoreApplication.sendEvent(self.tb, event)
        # 长按1后松开
        QTimer.singleShot(1000, self.custom_release)


    def custom_release(self):
        event = QMouseEvent(QEvent.MouseButtonRelease, self.p_pos, Qt.MouseButton.LeftButton, Qt.MouseButton.LeftButton, Qt.NoModifier)
        QCoreApplication.sendEvent(self.tb, event)
        print("鼠标松开")

    def click_slot(self):
        print("按钮被点击")



if __name__ == '__main__':
    app = QApplication(sys.argv)

    parent_dir_path, file_name = os.path.split(os.path.abspath(__file__))
    _, parent_dir_name = os.path.split(parent_dir_path)

    app.setApplicationDisplayName(f"[{parent_dir_name}][{file_name}]")

    w = Widget()
    w.show()
    sys.exit(app.exec_())
