How to Disable Keyboard Interaction for Vue Diagram?

By default, the Syncfusion® Vue Diagram provides support for interacting with elements using key gestures, with several in-built commands bound to specific key combinations. You can refer to the following link to see the default key bindings for the diagram.

Keyboard Documentation: Keyboard Commands in Vue

Currently, there is no direct option to disable all keyboard interactions in the diagram component. However, you can achieve this by binding keyboard events using event listeners for Keydown and Keyup event and calling event.preventDefault() to prevent the default action, as well as event.stopPropagation() to stop the event from propagating up or down the DOM tree. This approach prevents keyboard events from reaching the diagram component and triggering any actions.

Refer to the following code snippet and sample for guidance:

<script>
export default {
 methods: {
   // Method to block keyboard events
   blockKeyboardEvent(event) {
     event.preventDefault();  // Block system keyboard actions
     event.stopPropagation(); // Prevent event from reaching diagram
   },
 },
 mounted() {
   const diagramElement = document.getElementById('diagram');

   // Add event listeners
   diagramElement.addEventListener('keydown', this.blockKeyboardEvent, true);
   diagramElement.addEventListener('keyup', this.blockKeyboardEvent, true);
 },
 beforeUnmount() {
   const diagramElement = document.getElementById('diagram');

   // Remove event listeners on component unmount
   diagramElement.removeEventListener('keydown', this.blockKeyboardEvent, true);
   diagramElement.removeEventListener('keyup', this.blockKeyboardEvent, true);
 }
};
</script>
