Description:

needed sometimes, when a full application is embeded into an ExtendedComboBox
or subcanvas AND you want to avoid, that this application accesses the outer
application's aspects (by returning a private application instance).

Notice: you may have to manually set this view's application to be the embedded app
       (i.e. via #application:) unless it is set by #client:....

see self-embedding example in CodingExamples_GUI::GUIDemoExtendedComboBox

Instance protocol:

 application

return the value of the instance variable 'application' (automatically generated)

 application: something

set the value of the instance variable 'application' (automatically generated)

 buildMenu: aBoolean

if true, the main menu is also built. Default is false

 client: anApplication spec: aWindowSpecOrSpecSymbol builder: aBuilder

(comment from inherited method)
release existing components and generate new components from
the given windowSpec, using the given builder.

 client: anApplication spec: aWindowSpecOrSpecSymbol builder: aBuilder withMenu: withMenu

(comment from inherited method)
release existing components and generate new components from
the given windowSpec, using the given builder.
ATTENTION: this is a low level interface.
TODO: this code is so ugly and badly designed - it must be redesigned
or at least well documented.

 destroy

(comment from inherited method)
unmap & destroy - make me invisible, destroy subviews then
make me unknown to the device

 keyPress: key x: x y: y

(comment from inherited method)
a key has been pressed. If there are components,
pass it to the corresponding one.
Otherwise, forward it to the superview, if there is any.

 preRealize

(comment from inherited method)
invoked right before a view is realized.
Can be redefined in subclasses to perform delayed actions.

 realize

(comment from inherited method)
realize - make visible;
realizing is done very late (after layout is fixed) to avoid
visible rearranging of windows on the screen
