deleteSelectedWithConfirmation method

Future<void> deleteSelectedWithConfirmation()

Deletes all selected nodes and connections with lock check and confirmation.

This async method processes all selected items, respecting:

• Behavior mode (must allow deletion)
• Lock status (locked items are skipped)
• Before-delete callbacks (if provided, allows confirmation dialogs)

Items are processed sequentially to allow for individual confirmation dialogs. If a callback returns false for an item, that item is skipped but processing continues for remaining items.

Example:

await controller.deleteSelectedWithConfirmation();

Implementation

Future<void> deleteSelectedWithConfirmation() async {
  // Check behavior first
  if (!behavior.canDelete) return;

  // Process nodes
  final nodeIds = selectedNodeIds.toList();
  for (final nodeId in nodeIds) {
    await requestDeleteNode(nodeId);
  }

  // Process connections
  final connectionIds = selectedConnectionIds.toList();
  for (final connectionId in connectionIds) {
    await requestDeleteConnection(connectionId);
  }
}
