好的,我可以为您基于pyqt5设计一个UI代码。以下是代码示例:
```python
import sys
from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QFileDialog, QLabel, QVBoxLayout, QWidget
class VideoPlayer(QMainWindow):
def __init__(self):
super().__init__()
# 设置主窗口属性
self.setWindowTitle("视频播放器")
self.setFixedSize(400, 300)
# 创建按钮
self.local_video_button = QPushButton("选择本地视频", self)
self.local_video_button.clicked.connect(self.select_local_video)
self.total_people_button = QPushButton("统计总人数", self)
self.total_people_button.clicked.connect(self.show_total_people)
# 创建标签
self.file_path_label = QLabel(self)
self.total_people_label = QLabel(self)
# 创建布局
layout = QVBoxLayout()
layout.addWidget(self.local_video_button)
layout.addWidget(self.file_path_label)
layout.addWidget(self.total_people_button)
layout.addWidget(self.total_people_label)
# 创建中心小部件
widget = QWidget()
widget.setLayout(layout)
self.setCentralWidget(widget)
def select_local_video(self):
# 选择本地视频
file_dialog = QFileDialog(self, "选择本地视频", "", "Video (*.mp4 *.flv)")
file_dialog.setFileMode(QFileDialog.ExistingFile)
if file_dialog.exec_():
file_path = file_dialog.selectedFiles()[0]
self.file_path_label.setText(file_path)
def show_total_people(self):
# 统计总人数,此处为示例,可自行替换为统计代码
total_people = 100
self.total_people_label.setText("总人数:%d" % total_people)
if __name__ == "__main__":
app = QApplication(sys.argv)
player = VideoPlayer()
player.show()
sys.exit(app.exec_())
```
该代码实现了一个简单的视频播放器UI界面,包括选择本地视频按钮和统计总人数按钮。用户可以通过选择本地视频按钮选择本地视频文件,统计总人数按钮可进行人数统计。该程序中统计人数为示例代码,用户可自行替换为实际统计人数代码。
