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.
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
WidgetComponent
.connectedCallback
Defined in
packages/blocks/src/root-block/widgets/drag-handle/drag-handle.ts:1509
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.
disconnectedCallback() {
super.disconnectedCallback();
window.removeEventListener('keydown', this._handleKeydown);
}
An element may be re-connected after being disconnected.
Returns
void
Overrides
WidgetComponent

render()
render():
TemplateResult
<1
>
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
TemplateResult

styles
styles
static
styles:CSSResult
Array of styles to apply to the element. The styles should be defined using the css tag function, via constructible stylesheets, or imported from native CSS module scripts.
Note on Content Security Policy:
Element styles are implemented with <style>
tags when the browser doesn't support adopted StyleSheets. To use such <style>
tags with the style-src CSP directive, the style-src value must either include 'unsafe-inline' or nonce-<base64-value>
with <base64-value>
replaced be a server-generated nonce.
To provide a nonce to use on generated <style>
elements, set window.litNonce
to a server-generated nonce in your page's HTML, before loading application code:
<script>
// Generated and unique per request:
window.litNonce = 'a1b2c3d4';
</script>
Nocollapse
Overrides
WidgetComponent.styles

packages/blocks/src/root-block/widgets/drag-handle/drag-handle.ts:87
updates
firstUpdated()
firstUpdated():
void
Invoked when the element is first updated. Implement to perform one time work on the element after update.
firstUpdated() {
this.renderRoot.getElementById('my-text-area').focus();
}
Setting properties inside this method will trigger the element to update again after this update cycle completes.
Returns
void
Overrides
