Overview

As described in issue #961 , the current version does not display any tooltip when the plugin PopupMenuHandler is not added to the list of the plugins. This is a common case when BaseGraph is used over Graph (as suggested in the documentation, BaseGraph should always be the choice for production).

The solution now handle this case correctly: when popupMenuHandler is not available (undefined) or the menu is not showing, then the tooltip will be displayed.

!popupMenuHandler?.isMenuShowing()

To verify that the solution works, use the story "Wires" which has been edited in order to not include the PopupMenuHandler. Tooltips on vertices and edges should now be displayed correctly.

Walkthrough

Use optional chaining when checking PopupMenuHandler in TooltipHandler so tooltips can show when PopupMenuHandler is absent or not showing; remove PopupMenuHandler from the plugins array in the Wires story.

Changes

Cohort / File(s) Change Summary
TooltipHandler logic fix
packages/core/src/view/plugins/TooltipHandler.ts		 Replaced explicit truthy check with optional chaining in the tooltip guard (!popupMenuHandler?.isMenuShowing()), allowing tooltips when PopupMenuHandler is absent or its isMenuShowing() is false.
Wires story plugin configuration
packages/html/stories/Wires.stories.ts		 Removed PopupMenuHandler from the Graph plugins array in the Wires story.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

  • Check TooltipHandler reset/display logic to ensure optional chaining covers absent plugin and preserves previous behavior when plugin exists.
  • Verify the Wires story renders as expected without registering PopupMenuHandler and that no other stories rely on it.
