renderVersionMismatch() ​

renderVersionMismatch(expectedVersion, actualVersion): TemplateResult

Render a warning message when the block version is mismatched.

Parameters ​

• expectedVersion: number

If the schema is not found, the expected version is -1. Which means the block is not supported in the current editor.

• actualVersion: number

The version of the block's crdt data.

Returns ​

TemplateResult

Inherited from ​

BlockComponent.renderVersionMismatch

Defined in ​

packages/framework/block-std/src/view/element/block-component.ts:275

toZIndex() ​

toZIndex(): string

updateZIndex() ​

updateZIndex(): void

Returns ​

lifecycle ​

connectedCallback() ​

connectedCallback(): void

Invoked when the component is added to the document's DOM.

In connectedCallback() you should setup tasks that should only occur when the element is connected to the document. The most common of these is adding event listeners to nodes external to the element, like a keydown event handler added to the window.

ts
connectedCallback() {
  super.connectedCallback();
  addEventListener('keydown', this._handleKeydown);
}

Typically, anything done in connectedCallback() should be undone when the element is disconnected, in disconnectedCallback().

Returns ​

void

Overrides ​

BlockComponent.connectedCallback

Defined in ​

packages/framework/block-std/src/view/element/gfx-block-component.ts:57

disconnectedCallback() ​

disconnectedCallback(): void

Invoked when the component is removed from the document's DOM.

This callback is the main signal to the element that it may no longer be used. disconnectedCallback() should ensure that nothing is holding a reference to the element (such as event listeners added to nodes external to the element), so that it is free to be garbage collected.

ts
disconnectedCallback() {
  super.disconnectedCallback();
  window.removeEventListener('keydown', this._handleKeydown);
}

An element may be re-connected after being disconnected.

Returns ​

void

Inherited from ​

BlockComponent.disconnectedCallback

Defined in ​

packages/framework/block-std/src/view/element/block-component.ts:243

rendering ​

createRenderRoot() ​

createRenderRoot(): HTMLElement | DocumentFragment

Returns ​

HTMLElement | DocumentFragment

Inherited from ​

BlockComponent.createRenderRoot

Defined in ​

packages/framework/block-std/src/view/element/shadowless-element.ts:28

render() ​

render(): unknown

Invoked on each update to perform rendering tasks. This method may return any value renderable by lit-html's ChildPart - typically a TemplateResult. Setting properties inside this method will not trigger the element to update.

Returns ​

unknown

Inherited from ​

BlockComponent.render

Defined in ​

packages/framework/block-std/src/view/element/block-component.ts:258

styles ​

finalizeStyles() ​

protected static finalizeStyles(styles?): CSSResultOrNative[]

Takes the styles the user supplied via the static styles property and returns the array of styles to apply to the element. Override this method to integrate into a style management system.

Styles are deduplicated preserving the last instance in the list. This is a performance optimization to avoid duplicated styles that can occur especially when composing via subclassing. The last item is kept to try to preserve the cascade order with the assumption that it's most important that last added styles override previous styles.

Parameters ​

• styles?: CSSResultGroup

Returns ​

CSSResultOrNative[]

Nocollapse ​

Inherited from ​

BlockComponent.finalizeStyles

Defined in ​

packages/framework/block-std/src/view/element/shadowless-element.ts:8

updates ​

getUpdateComplete() ​

protected getUpdateComplete(): Promise<boolean>

Override point for the updateComplete promise.

It is not safe to override the updateComplete getter directly due to a limitation in TypeScript which means it is not possible to call a superclass getter (e.g. super.updateComplete.then(...)) when the target language is ES5 (https://github.com/microsoft/TypeScript/issues/338). This method should be overridden instead. For example:

ts
class MyElement extends LitElement {
  override async getUpdateComplete() {
    const result = await super.getUpdateComplete();
    await this._myChild.updateComplete;
    return result;
  }
}

Returns ​

Promise<boolean>

A promise of a boolean that resolves to true if the update completed without triggering another update.

Inherited from ​

BlockComponent.getUpdateComplete

Defined in ​

packages/framework/block-std/src/view/element/block-component.ts:252

scheduleUpdate() ​

scheduleUpdate(): Promise<void>

Schedules an element update. You can override this method to change the timing of updates by returning a Promise. The update will await the returned Promise, and you should resolve the Promise to allow the update to proceed. If this method is overridden, super.scheduleUpdate() must be called.

For instance, to schedule updates to occur just before the next frame:

ts
override protected async scheduleUpdate(): Promise<unknown> {
  await new Promise((resolve) => requestAnimationFrame(() => resolve()));
  super.scheduleUpdate();
}

Returns ​

Promise<void>

Overrides ​

BlockComponent.scheduleUpdate

Defined in ​
