Hello,
I have a
question about TabControl widget and dependency. I use a TabControl widget to manage
two sub application models A and B whose spec are used as subcanvas in the TabControl widget. The two sub application models are stored in an instance variable of
the main ApplicationModel as an Array (TabModels at: 1 -> ApplicationModel A
and TabModels at:2 -> ApplicationModel B).
Each sub-model
consists of one MVC, whose view is a composite view, treated as a viewHolder in
the spec. So the M is composed of numerous “unitModels” each one being the
model of one of the “unitViews” that compose the compositeView V. The M and the
V are stored as instance variables in the Sub Application Model.
My
TabsChanged method is :
aBuilder :=
self builder newSubBuilder.
(self
builder componentAt: #TabControl1) widget
client: (self
tabModels at: index)
spec: (self
specArray at: index)
builder: aBuilder
My problem
is that when I tab the TabControl widget, as it constructs the new subcanvas to be
displayed, the dependency of the first ApplicationModel are broken. I can
restore it as it is rebuilt, when tabbed again, by releasing all dependents of
the M and adding the V as a new dependent, but all the dependencies of the CompositeView, between the "unitModels" and the "unitViews", are also broken, and
the "unitViews" are no more wrappered. This leads me to re-build completely the compositeView
(using the method self add: borderedIn: for each unitView) so that the dependency is
restored (recreated in fact) as the TabControl widget is tabbed. But it produces some delay and strange screen
effects ...
What should
I do to optimize this? I think I maybe missed something in the way I build the
CompositeView but I have not found any insights in the pdf nor online…
Thanks in advance for
your help and my apologies if it has been already answered somewhere!
