使用JSON数据实现VS代码TreeDataProvider的简单示例

const vscode = require('vscode');

class TreeDataProvider {
    getTreeItem(element) {
        // 返回树形结构的节点
    }

    getChildren(element) {
        // 返回树形结构的子节点
    }
}

getTreeItem(element) {
    const treeItem = new vscode.TreeItem(element.label, vscode.TreeItemCollapsibleState.None);
    treeItem.description = element.description;
    treeItem.iconPath = new vscode.ThemeIcon(element.icon);
    // 设置其他属性

    return treeItem;
}

getChildren(element) {
    if (element) {
        // 返回element节点的子节点
    } else {
        // 返回根节点的子节点
    }
}

const treeDataProvider = new TreeDataProvider();
vscode.window.registerTreeDataProvider('treeView', treeDataProvider);

function activate(context) {
    console.log('Congratulations, your extension "treeViewExample" is now active!');

    // 其他代码

    context.subscriptions.push(vscode.commands.registerCommand('extension.showTreeView', () => {
        vscode.window.createTreeView('treeView', { treeDataProvider });
    }));
}
