from PyQt5.uic import loadUi from PyQt5.QtWidgets import QWidget class History(QWidget): def init(self,name): super().init(name) self.setParent(name) loadUi('ui/history.ui',self) #设定控件属性 self.history_text.setReadOnly(True) #—————————————————————————————————————————绑定信号—————————————————————————————————————————— self.btn_cancel.clicked.connect(lambda:self.hide())修改代码使得History部件不隐藏

如果您想让 `History` 部件不隐藏，只需要将 `self.hide()` 这行代码注释掉即可。修改后的代码如下：

from PyQt5.uic import loadUi
from PyQt5.QtWidgets import QWidget

class History(QWidget):
    def __init__(self, name):
        super().__init__(name)
        self.setParent(name)
        loadUi('ui/history.ui', self)
        
        # 设定控件属性
        self.history_text.setReadOnly(True)
        
        # 绑定信号
        self.btn_cancel.clicked.connect(lambda:self.hide())

这样做会在 `History` 部件初始化时将其显示出来，并且不会隐藏。

这是一段Python代码，通过使用import关键字导入了sys、threading、time等模块。同时，也导入了PyQt5.QtWidgets的部分类和PyQt5.uic模块。此外，还导入了pandas和random模块，用于处理数据和生成随机数等操作。

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()
