Defining a dynamic context submenu [message #1661217]

Hi everyone, another question about context menus.

I would like to define a context menu item enabling to display a submenu whose contents are populated dynamically, typically to easily create dynamic menus such as in the "Create child" and "Create sibling" menu items in the EMF-generated editor's context menu.

It is possible to define such dynamic menu items with Sirius ?

Thanks in advance,

François

Hello,

Among the tools available in Sirius, create a new "Popop menu". Set the
name of your parent context menu as the ID or Label of this tool.
Then create an operation action for each submenu action you need. In the
precondition field, write a boolean expression that should be true if
you want to display this contextual action for the selected element.

Regards,
Steve

Thank you very much, this approach should work with the examples I mentioned.

I also would like to know if there is a way to handle a dynamic menu in case its contents can only be known at runtime, for example if the menu items depend on the contents of the edited model.

I might be missing a point, but I guess this only add some condition on
your expression, like checking the number of children (eContents()->size
< x) or if a certain feature starts with a certain prefix
(featureName.startsWith("prefix")). If the expression is too complex you
can use a java service.

hello,

You can contribute your popup menu programmatically by using org.eclipse.ui.menus.

Using this ID: popup:org.eclipse.gmf.runtime.diagram.ui.DiagramEditorContextMenu for locationURI property of menuContribution
