主要窗口

workbench.ts中startup里面Workbench负责创建主界面 src/vs/workbench/browser/workbench.ts

startup(): IInstantiationService {
    try {

        ...

        instantiationService.invokeFunction(async accessor => {

            // 渲染主工作界面
            this.renderWorkbench(instantiationService, accessor.get(INotificationService) as NotificationService, storageService, configurationService);

            // 界面布局
            this.createWorkbenchLayout(instantiationService);

            // Layout
            this.layout();

            // Restore
            try {
                await this.restoreWorkbench(accessor.get(IEditorService), accessor.get(IEditorGroupsService), accessor.get(IViewletService), accessor.get(IPanelService), accessor.get(ILogService), lifecycleService);
            } catch (error) {
                onUnexpectedError(error);
            }
        });

        return instantiationService;
    } catch (error) {
        onUnexpectedError(error);

        throw error; // rethrow because this is a critical issue we cannot handle properly here
    }
}

渲染主工作台,渲染完之后加入到container中,container加入到parent, parent就是body了。

this.parent.appendChild(this.container);

private renderWorkbench(instantiationService: IInstantiationService, notificationService: NotificationService, storageService: IStorageService, configurationService: IConfigurationService): void {

        ...

        //TITLEBAR_PART 顶部操作栏
        //ACTIVITYBAR_PART 最左侧菜单选项卡
        //SIDEBAR_PART 左侧边栏,显示文件,结果展示等
        //EDITOR_PART 右侧窗口,代码编写,欢迎界面等
        //STATUSBAR_PART 底部状态栏
        [
            { id: Parts.TITLEBAR_PART, role: 'contentinfo', classes: ['titlebar'] },
            { id: Parts.ACTIVITYBAR_PART, role: 'navigation', classes: ['activitybar', this.state.sideBar.position === Position.LEFT ? 'left' : 'right'] },
            { id: Parts.SIDEBAR_PART, role: 'complementary', classes: ['sidebar', this.state.sideBar.position === Position.LEFT ? 'left' : 'right'] },
            { id: Parts.EDITOR_PART, role: 'main', classes: ['editor'], options: { restorePreviousState: this.state.editor.restoreEditors } },
            { id: Parts.PANEL_PART, role: 'complementary', classes: ['panel', this.state.panel.position === Position.BOTTOM ? 'bottom' : 'right'] },
            { id: Parts.STATUSBAR_PART, role: 'contentinfo', classes: ['statusbar'] }
        ].forEach(({ id, role, classes, options }) => {
            const partContainer = this.createPart(id, role, classes);

            if (!configurationService.getValue('workbench.useExperimentalGridLayout')) {
                // TODO@Ben cleanup once moved to grid
                // Insert all workbench parts at the beginning. Issue #52531
                // This is primarily for the title bar to allow overriding -webkit-app-region
                this.container.insertBefore(partContainer, this.container.lastChild);
            }

            this.getPart(id).create(partContainer, options);
        });

        // 将工作台添加至container dom渲染
        this.parent.appendChild(this.container);
    }

workbench最后调用this.layout()方法,将窗口占据整个界面,渲染完成

layout(options?: ILayoutOptions): void {
        if (!this.disposed) {
            this._dimension = getClientArea(this.parent);

            if (this.workbenchGrid instanceof Grid) {
                position(this.container, 0, 0, 0, 0, 'relative');
                size(this.container, this._dimension.width, this._dimension.height);

                // Layout the grid widget
                this.workbenchGrid.layout(this._dimension.width, this._dimension.height);
            } else {
                this.workbenchGrid.layout(options);
            }

            // Emit as event
            this._onLayout.fire(this._dimension);
        }
    }
