QUESTION
 How do I dynamically add icons to a container and use
 context menus in different variations?

ANSWER
 To learn how to dynamically add icons to a container during
 runtime, instead of statically during development time, see
 the example in the VisualAge User's Guide and Reference Manual
 pages 229-236.  This example allows you to use a context
 menu while clicking the second mouse button anywhere in
 the container surface except on top of the icons.

 There are other ways to use the context menu.  For instance,
 you may want to be able to bring up the context menu while both
 clicking the second mouse button on the container surface and on
 top of the icons.  To do this, you just have to modify the following
 method:  fillContainer: itemsCollection defaultAction: aScriptName

 iconGadget := (AbtIconGadgetView new
        label: each;
        largeIcon: icon;
        parentView: container;
        openWidget;
        menu: ((self subpartNamed: 'Menu') yourself)   <=add this line
        yourself).

 By adding that one line, you can now click anywhere inside the
 container including on top of the icons and see a context menu.

 Another variation to the use of context menus within a container
 is to click the second mouse button on top of the icon and see
 a context menu but not see a context menu when you click the
 second mouse button from anywhere else in the container.  To do
 this you will edit the same method.  But now, that same segment of
 code will look like this:

 iconGadget := (AbtIconGadgetView new
        label: each;
        largeIcon: icon;
        parentView: container;
        openWidget;
        menu: (((self subpartNamed: 'Menu') yourself)
                createWidget;
                setPostCreationSettings;
                yourself);
        yourself).

 In addition to changing this piece of code, you also must delete
 the connection between the container's menu attribute and the
 menu's self attribute.

 After these few changes, you should now be able to only see a
 context menu by clicking the second mouse button on the icons
 only, not on the container's surface.
