Ui_userProfile, _ = uic.loadUiType("./UI/subWindow_userProfile.ui")

这是一个Python代码段，使用了PyQt库中的uic.loadUiType()方法，用于加载一个名为"subWindow_userProfile.ui"的用户界面文件。该文件是使用Qt Designer创建的，包含了用户界面的设计和布局。加载该文件后，会返回两个对象，一个是用户界面类，另一个是基类，可以用于创建该用户界面的实例。

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView, QMessageBox, QDialog, QTableWidgetItem from PyQt5.QtSql import QSqlDatabase, QSqlQuery, QSqlTableModel from PyQt5 import uic# 加载 UI 文件UI_FILE = 'main.ui' Ui_MainWindow, QtBaseClass = uic.loadUiType(UI_FILE)

这段代码是用于使用 PyQt5 模块开发 GUI 应用程序的。其中包含了加载 UI 文件、创建主窗口、添加表格视图、弹出消息框、创建对话框、添加表格项等相关操作。此外，还使用了 QSqlDatabase、QSqlQuery、QSqlTableModel 等模块实现了数据库的连接、查询和数据模型的创建。

使用QTimer对象代替QBasicTimer对象，修改程序class MyWindow(QWidget): def init(self): super().init() self.thread_list = [] self.color_photo_dir = os.path.join(os.getcwd(), "color_photos") self.depth_photo_dir = os.path.join(os.getcwd(), "depth_photos") self.image_thread = None self.saved_color_photos = 0 # 定义 saved_color_photos 属性 self.saved_depth_photos = 0 # 定义 saved_depth_photos 属性 self.init_ui() def init_ui(self): self.ui = uic.loadUi("C:/Users/wyt/Desktop/D405界面/intelrealsense1.ui") self.open_btn = self.ui.pushButton self.color_image_chose_btn = self.ui.pushButton_3 self.depth_image_chose_btn = self.ui.pushButton_4 self.open_btn.clicked.connect(self.open) self.color_image_chose_btn.clicked.connect(lambda: self.chose_dir(self.ui.lineEdit, "color")) self.depth_image_chose_btn.clicked.connect(lambda: self.chose_dir(self.ui.lineEdit_2, "depth")) def open(self): self.profile = self.pipeline.start(self.config) self.is_camera_opened = True self.label.setText('相机已打开') self.label.setStyleSheet('color:green') self.open_btn.setEnabled(False) self.close_btn.setEnabled(True) self.image_thread = ImageThread(self.pipeline, self.color_label, self.depth_label, self.interval, self.color_photo_dir, self.depth_photo_dir, self._dgl) self.image_thread.saved_color_photos_signal.connect(self.update_saved_color_photos_label) self.image_thread.saved_depth_photos_signal.connect(self.update_saved_depth_photos_label) self.image_thread.start() def chose_dir(self, line_edit, button_type): my_thread = MyThread(line_edit, button_type) my_thread.finished_signal.connect(self.update_line_edit) self.thread_list.append(my_thread) my_thread.start()
