一、vscode.window 核心架构图

二、核心功能详解

1. 窗口管理

// 获取当前活动窗口
const activeWindow = vscode.window.activeTextEditor;// 切换窗口焦点
vscode.window.showTextDocument(document, { preview: false });// 监听窗口变化
vscode.window.onDidChangeActiveTextEditor(editor => {console.log(`Active editor changed to: ${editor.document.fileName}`);
});

2. 消息提示系统

// 基础消息提示
vscode.window.showInformationMessage('操作成功', '确定');// 带按钮的消息提示
vscode.window.showWarningMessage('确认删除?', '是', '否').then(selection => {if (selection === '是') {// 执行删除操作}
});// 错误消息提示
vscode.window.showErrorMessage('操作失败', { detail: '详细错误信息' });

3. 状态栏管理

// 创建状态栏项
const statusItem = vscode.window.createStatusBarItem(vscode.StatusBarAlignment.Left, 100);
statusItem.text = '$(zap) 运行中';
statusItem.tooltip = '当前任务状态';
statusItem.show();// 动态更新状态
function updateStatus(text: string, color?: string) {statusItem.text = text;if (color) {statusItem.color = color;}
}// 状态栏点击事件
statusItem.command = 'myExtension.showDetails';
vscode.commands.registerCommand('myExtension.showDetails', () => {vscode.window.showInformationMessage('状态栏点击事件触发');
});

4. 用户输入处理

// 显示输入框
vscode.window.showInputBox({prompt: '请输入文件名',value: 'newfile',validateInput: (value) => {if (!value.match(/^[a-zA-Z0-9_-]+$/)) {return '文件名只能包含字母、数字、下划线和横线';}return null;}
}).then(value => {if (value) {// 处理输入内容}
});// 显示快速选择列表
vscode.window.showQuickPick(['选项1', '选项2', '选项3'], {placeHolder: '请选择一个选项',canPickMany: true
}).then(selections => {if (selections) {vscode.window.showInformationMessage(`已选择: ${selections.join(', ')}`);}
});

5. 进度指示器

// 显示通知栏进度
vscode.window.withProgress({location: vscode.ProgressLocation.Notification,title: "处理中",cancellable: true
}, (progress, token) => {return new Promise(resolve => {let count = 0;const interval = setInterval(() => {if (token.isCancellationRequested) {clearInterval(interval);resolve();}progress.report({ increment: 10, message: `${count}%` });count += 10;if (count > 100) {clearInterval(interval);resolve();}}, 500);});
});// 显示状态栏进度
const progressItem = vscode.window.createStatusBarItem(vscode.StatusBarAlignment.Right);
progressItem.text = '0%';
progressItem.show();// 更新进度
let percent = 0;
const interval = setInterval(() => {percent += 5;progressItem.text = `${percent}%`;if (percent >= 100) {clearInterval(interval);progressItem.hide();}
}, 500);

6. Webview管理

// 创建Webview面板
const panel = vscode.window.createWebviewPanel('myWebview','交互式面板',vscode.ViewColumn.One,{enableScripts: true,localResourceRoots: [vscode.Uri.file(path.join(extensionPath, 'resources'))]}
);// 复用Webview实例
let webviewPanel: vscode.WebviewPanel | undefined;vscode.commands.registerCommand('myExtension.toggleWebview', () => {if (webviewPanel) {webviewPanel.reveal();} else {webviewPanel = vscode.window.createWebviewPanel(...);// 配置Webview内容webviewPanel.onDidDispose(() => {webviewPanel = undefined;});}
});

三、高级功能与最佳实践

1. 多窗口协调

// 获取所有打开的编辑器
vscode.window.visibleTextEditors.forEach(editor => {console.log(`打开的文件: ${editor.document.fileName}`);
});// 监听新窗口打开
vscode.window.onDidOpenTextDocument(document => {if (document.languageId === 'typescript') {vscode.window.showInformationMessage(`TypeScript文件已打开: ${document.fileName}`);}
});

2. 自定义视图容器

// 注册自定义视图
vscode.window.registerWebviewViewProvider('myCustomView', {resolveWebviewView: (webviewView, context) => {webviewView.webview.options = {enableScripts: true};webviewView.webview.html = `<h1>自定义视图内容</h1>`;}
});

3. 终端集成

// 创建终端
const terminal = vscode.window.createTerminal('My Terminal');
terminal.show();
terminal.sendText('echo "Hello VS Code"');// 监听终端输出
vscode.window.onDidWriteTerminalData(e => {if (e.terminal === terminal) {console.log(`终端输出: ${e.data}`);}
});

4. 无障碍支持

// 设置ARIA标签
vscode.window.setStatusBarMessage('任务完成', 5000, {ariaLive: 'assertive'
});// 描述操作
vscode.window.showInformationMessage('文件已保存', {modal: true,detail: '保存操作成功完成',description: '文件路径: /path/to/file'
});

四、错误处理与资源管理

1. 安全释放资源

class MyPanel {private disposable: vscode.Disposable;constructor(panel: vscode.WebviewPanel) {this.disposable = vscode.Disposable.from(panel.onDidDispose(() => this.dispose()),vscode.window.onDidChangeActiveTextEditor(() => this.update()));}dispose() {this.disposable.dispose();}
}

2. 统一错误处理

function handleError(error: unknown) {if (error instanceof Error) {vscode.window.showErrorMessage(`错误: ${error.message}`, {detail: error.stack});console.error('扩展错误:', error);} else {vscode.window.showErrorMessage('未知错误发生');}
}
