這篇文章主要為大家詳細介紹了如何模擬Everything，即通過python+PyQt5來實現(xiàn)可視化文件的高速查找，文中的示例代碼講解詳細，需要的可以參考一下

一、功能

模擬Everything，通過python+PyQt5來實現(xiàn)可視化文件的高速查找。

二、代碼

import os
import threading
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit, QTextBrowser, QPushButton, QComboBox
from PyQt5.QtGui import QFont
from PyQt5.QtCore import Qt, pyqtSignal, QObject

        super().__init__()
        self.disk = disk
        self.search_text = search_text
        self.found_files = []
 
    def search_files(self):
        for root, dirs, files in os.walk(self.disk):
            for file in files:
                if self.search_text.lower() in file.lower():
                    file_path = os.path.join(root, file)
                    self.found_files.append(file_path)
                    self.search_result_found.emit(file_path)
 
        self.search_finished.emit()

        self.search_status_label.adjustSize()

                file_search_thread.search_finished.connect(self.search_finished)
 
                self.worker_thread = threading.Thread(target=file_search_thread.search_files)
                self.worker_thread.start()
 
    def display_result(self, file_path):
        self.search_results.append(file_path)
 
    def search_finished(self):
        self.search_status_label.setText("搜索完成")
        self.search_status_label.adjustSize()
        self.worker_thread.join()
