From 885d87dff84103f7036e4b074a07dc1038acfb1e Mon Sep 17 00:00:00 2001 From: Misaka_Company Date: Thu, 5 Feb 2026 14:06:30 +0800 Subject: [PATCH] feat: add progress callback mechanism for real-time updates in data extraction - Add ProgressInfo and ProgressCalculator classes for structured progress tracking - Implement RealtimeOutput for immediate log display without buffering - Add progress callback support to DiscreteMaterialPlanExtractor - Use queue-based thread-safe communication for GUI progress updates - Fix log output issue where all content appeared at once after completion Co-Authored-By: Claude Sonnet 4.5 --- gui/data_extraction_tab.py | 63 ++++++--- gui/progress.py | 97 ++++++++++++++ gui/utils.py | 39 ++++++ utils/离散备料计划维护数据提取.py | 212 +++++++++++++++++++++--------- 4 files changed, 329 insertions(+), 82 deletions(-) create mode 100644 gui/progress.py create mode 100644 gui/utils.py diff --git a/gui/data_extraction_tab.py b/gui/data_extraction_tab.py index 9f0852d..37ea3b5 100644 --- a/gui/data_extraction_tab.py +++ b/gui/data_extraction_tab.py @@ -9,13 +9,15 @@ import os import sys import threading +import queue import tkinter as tk from tkinter import ttk, filedialog, messagebox from pathlib import Path -from io import StringIO from contextlib import redirect_stdout from gui.widgets import FileSelector, LogText from gui.config_manager import ConfigManager +from gui.progress import ProgressInfo, ProgressCalculator +from gui.utils import RealtimeOutput class DataExtractionTab(ttk.Frame): @@ -34,6 +36,11 @@ class DataExtractionTab(ttk.Frame): self.extracting = False self.extractor = None self.extraction_thread = None + self.progress_calculator = ProgressCalculator() + self.progress_queue = queue.Queue() # 进度更新队列 + + # 启动进度更新轮询 + self._poll_progress_queue() self.create_widgets() @@ -163,6 +170,7 @@ class DataExtractionTab(ttk.Frame): self.start_button.config(state=tk.DISABLED) self.stop_button.config(state=tk.NORMAL) self.progress_bar['value'] = 0 + self.status_label.config(text="正在登录...") self.log_text.clear() self.log_text.info("开始数据提取...") @@ -195,25 +203,24 @@ class DataExtractionTab(ttk.Frame): verbose=self.verbose_var.get() ) -
