应用概述

这个应用程序提供了一个图形用户界面，允许用户浏览文件系统，查看和管理Python源代码文件。它的主要功能包括：

扫描指定文件夹中的所有.py文件
在列表视图中显示文件信息
搜索文件
编辑文件备注和有效性标志
将文件信息保存到SQLite数据库
从数据库中检索和显示文件信息
在Visual Studio Code中打开选定的文件
将文件信息导出到Excel

让我们深入了解这个应用的一些关键特性和它们的实现方式。

核心功能解析

1. 文件扫描和显示

应用程序使用Python的os模块来遍历指定文件夹及其子文件夹，查找所有的.py文件。文件信息（包括文件名、完整路径和修改日期）被收集并按最近修改日期排序，然后显示在一个wx.ListCtrl控件中。

def on_scan(self, event):
    folder_path = self.folder_picker.GetPath()
    if not folder_path:
        wx.MessageBox("Please select a folder.", "Error", wx.OK | wx.ICON_ERROR)
        return

    self.listview1.DeleteAllItems()

    py_files = []
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            if file.endswith(".py"):
                full_path = os.path.join(root, file)
                date_modified = os.path.getmtime(full_path)
                date_str = wx.DateTime.FromTimeT(int(date_modified)).FormatISOCombined()
                py_files.append((file, full_path, date_str, date_modified))

    # Sort files by date modified (most recent first)
    py_files.sort(key=lambda x: x[3], reverse=True)

    for file, full_path, date_str, _ in py_files:
        index = self.listview1.InsertItem(self.listview1.GetItemCount(), file)
        self.listview1.SetItem(index, 1, full_path)
        self.listview1.SetItem(index, 2, date_str)

2. 文件搜索

搜索功能允许用户在文件名或完整路径中查找匹配项。匹配的项目会被高亮显示，使用户能够快速定位所需的文件。

def search_in_listview(self, listview, search_term):
    for i in range(listview.GetItemCount()):
        item = listview.GetItem(i)
        if search_term in item.GetText().lower() or search_term in listview.GetItem(i, 1).GetText().lower():
            item.SetBackgroundColour(wx.YELLOW)
            listview.SetItem(item)
            listview.EnsureVisible(i)
        else:
            item.SetBackgroundColour(wx.WHITE)
            listview.SetItem(item)

    if not search_term:
        for i in range(listview.GetItemCount()):
            item = listview.GetItem(i)
            item.SetBackgroundColour(wx.WHITE)
            listview.SetItem(item)

3. 数据库集成

应用程序使用SQLite数据库来持久化文件信息。用户可以将文件信息保存到数据库，也可以从数据库中检索信息。这个功能特别有用，因为它允许用户在不同的会话中保留他们的文件管理状态。

def save_to_database(self, event):
    try:
        conn = sqlite3.connect(self.db_path)
        cursor = conn.cursor()

        # Ensure table exists
        cursor.execute('''CREATE TABLE IF NOT EXISTS files (
                            id INTEGER PRIMARY KEY AUTOINCREMENT,
                            file_name TEXT,
                            full_path TEXT,
                            date_modified TEXT,
                            remarks TEXT,
                            valid INTEGER)''')

        # Append new records or update existing ones
        for index in range(self.listview2.GetItemCount()):
            file_name = self.listview2.GetItemText(index)
            full_path = self.listview2.GetItem(index, 1).GetText()
            date_modified = self.listview2.GetItem(index, 2).GetText()
            remarks = self.listview2.GetItem(index, 3).GetText()
            valid = self.listview2.GetItem(index, 4).GetText()
            valid = 1 if valid == "Yes" else 0

            # Check if the record already exists
            cursor.execute('SELECT * FROM files WHERE full_path = ?', (full_path,))
            if cursor.fetchone() is None:
                # If it doesn't exist, insert a new record
                cursor.execute('INSERT INTO files (file_name, full_path, date_modified, remarks, valid) VALUES (?, ?, ?, ?, ?)',
                            (file_name, full_path, date_modified, remarks, valid))
            else:
                # If it exists, update the existing record
                cursor.execute('UPDATE files SET file_name = ?, date_modified = ?, remarks = ?, valid = ? WHERE full_path = ?',
                            (file_name, date_modified, remarks, valid, full_path))

        conn.commit()
    except sqlite3.Error as e:
        wx.MessageBox(f"Database error: {e}", "Error", wx.OK | wx.ICON_ERROR)
    finally:
        conn.close()

    wx.MessageBox("Data saved to the database.", "Info", wx.OK | wx.ICON_INFORMATION)

4. 与Visual Studio Code集成

为了提高开发效率，应用程序允许用户直接在Visual Studio Code中打开选定的Python文件。这是通过使用Python的subprocess模块来启动VS Code实现的。

def open_in_vscode(self, listview):
    selected = listview.GetFirstSelected()
    if selected == -1:
        wx.MessageBox("Please select a file to open", "Error", wx.OK | wx.ICON_ERROR)
        return

    full_path = listview.GetItem(selected, 1).GetText()
    subprocess.Popen(["C:\\Users\\86182\\AppData\\Local\\Programs\\Microsoft VS Code\\Code.exe", full_path])

5. 导出到Excel

为了方便数据共享和报告生成，应用程序提供了将文件信息导出到Excel的功能。这是使用openpyxl库实现的。

def on_export_excel(self, event):
    if self.listview3.GetItemCount() == 0:
        wx.MessageBox("No data to export.", "Error", wx.OK | wx.ICON_ERROR)
        return

    with wx.FileDialog(self, "Save Excel file", wildcard="Excel files (*.xlsx)|*.xlsx",
                       style=wx.FD_SAVE | wx.FD_OVERWRITE_PROMPT) as fileDialog:

        if fileDialog.ShowModal() == wx.ID_CANCEL:
            return

        pathname = fileDialog.GetPath()
        try:
            workbook = openpyxl.Workbook()
            sheet = workbook.active
            sheet.title = "Python Files"

            # Write headers
            headers = ["File Name", "Full Path", "Date Modified", "Remarks", "Valid"]
            for col, header in enumerate(headers, start=1):
                sheet.cell(row=1, column=col, value=header)

            # Write data
            for row in range(self.listview3.GetItemCount()):
                for col in range(self.listview3.GetColumnCount()):
                    value = self.listview3.GetItem(row, col).GetText()
                    sheet.cell(row=row+2, column=col+1, value=value)

            workbook.save(pathname)
            wx.MessageBox(f"Data exported to {pathname}", "Info", wx.OK | wx.ICON_INFORMATION)
        except Exception as e:
            wx.MessageBox(f"Failed to export data: {str(e)}", "Error", wx.OK | wx.ICON_ERROR)

效果如下
