ContextMenuProvider

The ContextMenuProvider allows applications to create their own context menus. The context menus are always defined on a view. To allow this, entry CONTEXT_MENUS is always available for each view, together with the ROOTUIELEMENTCONTAINER. Here, you can define your required context menu at runtime.

This menu is assigned to view elements as follows. Each view element has three options:

• It inherits the context menu from its parent (in the containment hierarchy).
• It hides its context menu.
• It provides a context menu (defined in the view).

These three cases are expressed in the property ContextMenuProvider Properties.

A "provider" sets property ContextMenuProvider Properties to the ID of its menu. To do this you need these two new properties in each (potential) provider. A provider can be:

• Each UI element subclass
• Several selected view element subclasses (TableColumn, Tab, etc)

Each UI element subclass is now automatically a (potential) provider. For the relevant view element subclasses the inheritance hierarchy has been changed so that it inherits from the ContextMenuProvider instead of from the ViewElement.
