- Glimmer::SWT::MenuProxy
- Defined in:

Overview
Proxy for org.eclipse.swt.widgets.Menu
Functions differently from other widget proxies.
Glimmer automatically detects if this is a drop down menu or pop up menu from its parent if no SWT style is passed in.
There are 3 possibilities:
-
SWT :bar style is passed in: Menu Bar
-
Parent is ShellProxy: Pop Up Menu (having style :pop_up)
-
Parent is another Menu: Drop Down Menu (having style :drop_down)
In order to get the SWT Menu object, one must call ‘#swt_widget`.
In the case of a Drop Down menu, this automatically creates an SWT MenuItem object with style :cascade
In order to retrieve the menu item widget proxy, one must call ‘#menu_item_proxy`
Follows the Proxy Design Pattern
