Context menu and multiple selection [message #1651838]

Hi,

For different purposes (comparison between two objects, synoptic view display, ...), I would like to define context menu items activable when several entries of a Tree representation are selected.

I noticed that the signatures of IExternalJavaAction.canExecute() and .execute() seem compatible with multiple selection: the argument is a Collection<? extends EObject> selections. But when I create an External Java action either under a Popup Menu or under an Operation (itself contained in a Popup Menu), I never can see the popup menu if I select more than one tree item (even with an empty precondition). Is there any way to enable such multi-object Java actions ?

Thanks in advance,

François

Hi Francois,

Indeed for tree representation, PopupMenu and OperationAction works only
with a single selected tree item. You can raise a bugzilla for a
enhancement. If you want to provide a change-set :) see in
org.eclipse.sirius.tree.ui.tools.internal.editor.DTreeMenuListener.addTreeItemMenus()
where we check if the selection is not multiple.

Best Regards.
