The component emits the following events:

imgDidChangeTriggered when an image is manipulated. Note: the event won't provide directly the image but rather its container element.CustomEvent<HTMLElement>
linkCreatedTriggered when a link is created by the user. The event detail is the container.CustomEvent<HTMLElement>
styleDidChangeTriggered when the style is modified (bold, italic, color, alignment, etc.). The event detail is the container.CustomEvent<HTMLElement>
stickyToolbarActivatedTriggered when the sticky toolbar would be activated or not. Useful for example if you want to catch the event to hide things in your footer, as the sticky toolbar is display above it.CustomEvent<boolean>
customActionTriggered when a custom action is selected. Its detail provide an action name, the Selection and an anchorLinkCustomEvent<InlineAction>


This component also export an async method reset() which will reset the inline editor (= hide it) and optionally clear its selection.

const element = document.querySelector('deckgo-inline-editor'); await element.reset(clearSelection: boolean, blurActiveElement?: boolean);


<p contenteditable slot="content">This text will be editable</p> <h1 contenteditable slot="title">This title too</h1> <deckgo-inline-editor></deckgo-inline-editor>


Worth to notice that this Web Component does not use the obsolete Document.execCommand() and is therefore kind of future proof.
