This hook is called whenever the content view of the screen changes
(due to a call to
Window.setContentView or
Window.addContentView).
Initialize the contents of the menu for panel 'featureId'. This is called if onCreatePanelView() returns null, giving you a standard menu in which you can place your items. It is only called once for the panel, the first time it is shown.
You can safely hold on to menu (and any items created from it), making modifications to it as desired, until the next time onCreatePanelMenu() is called for this feature.
| featureId | The panel being created. |
|---|---|
| menu | The menu inside the panel. |
Instantiate the view to display in the panel for 'featureId'. You can return null, in which case the default content (typically a menu) will be created for you.
| featureId | Which panel is being created. |
|---|
Called when the window has been attached to the window manager.
