如下所示：
#!/usr/bin/evn python3 # -*- coding: utf-8 -*- import sys from PyQt5.QtWidgets import (QApplication, QWidget, QScrollArea, QLabel) from PyQt5.QtCore import QEvent class TestWindow(QWidget): def __init__(self): super(TestWindow, self).__init__() self.resize(800, 600) self.move(0, 0) # self.setMouseTracking(False) self.last_time_move = 0 self.initUI() def initUI(self): self.central_widget = QWidget(self) self.scroll_area = QScrollArea(self) self.scroll_area.setGeometry(0, 0, 400, 400) self.scroll_area.setWidgetResizable(True) self.scroll_bar = self.scroll_area.verticalScrollBar() self.scroll_contents = QWidget() self.scroll_contents.setGeometry(0, 0, 400, 800) self.scroll_contents.setMinimumSize(380, 1000) self.label_1 = QLabel(self.scroll_contents) self.label_1.move(50, 100) self.label_1.setText("HelloRyan") self.label_2 = QLabel(self.scroll_contents) self.label_2.move(50, 200) self.label_2.setText("你好") self.label_3 = QLabel(self.scroll_contents) self.label_3.move(50, 300) self.label_3.setText("-----------") self.label_4 = QLabel(self.scroll_contents) self.label_4.move(50, 400) self.label_4.setText("542543255235432543252") self.label_5 = QLabel(self.scroll_contents) self.label_5.move(50, 500) self.label_5.setText("5432543262542") self.label_6 = QLabel(self.scroll_contents) self.label_6.move(50, 600) self.label_6.setText("4325432532") self.scroll_area.setWidget(self.scroll_contents) self.scroll_area.installEventFilter(self) # def mouseMoveEvent(self, event): # if event.pos().x() > 0 and event.pos().x() 0 and event.pos().y()
