Subject [jira] Commented: (PIVOT-181) Context menu handler
Date Wed, 22 Jul 2009 17:47:14 GMT

Noel Grandin commented on PIVOT-181:
------------------------------------

I'm sure that could work.

But what I'm concerned about is if you mix and match a custom container component from one
place with a custom child component from a different place, and the custom container component
is looking to add items into a context menu, while the child component is just going to take
control of the right-click event and do it's own thing.

Basically, I think we're creating a fragile situation, where custom components are easily
going to break each other.

And I don't really see the need - I've never seen any application do this kind of hierarchical
accumulation of context-menu items.

Just my thoughts, I'm not vehemently opposed, I just would prefer to minimise potential conflicts
of expectations.

> Create framework-level support for context menus by creating a Component.ContextMenuHandler
interface.  When the display host detects a right click, it will:
> 1) Get a reference to the lowest-level component that the mouse is over, and if that's
non-null...
> 2) Construct the path from the display to that component, instantiate a MenuPopup
> 3) Walk the path, passing the menu popup's menu to each ContextMenuHandler that is found
along the path
> 4) Open the menu popup if the menu is non-empty after the path has been walked
