使用PyQt5创建时间线

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QSlider
from PyQt5.QtCore import Qt

class Timeline(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        layout = QVBoxLayout()
        self.slider = QSlider(Qt.Horizontal)
        self.slider.setMinimum(0)
        self.slider.setMaximum(100)
        self.slider.setValue(50)
        self.slider.setTickPosition(QSlider.TicksBelow)
        self.slider.setTickInterval(10)
        layout.addWidget(self.slider)
        self.setLayout(layout)

        self.setWindowTitle('Timeline Example')
        self.setGeometry(300, 300, 400, 200)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    timeline = Timeline()
    timeline.show()
    sys.exit(app.exec_())
