Delegating views
Locked
 
|
Hoi,
What is the best way for an object to delegate one or more GTInspector views to other objects? I have been using a pattern like this: <gtInspectorPresentationOrder: 5> otherObject gtInspectorFooIn: composite but I am wondering whether there is a better way, and also whether this method is valid (I've occasionally seen odd behavior, like Inspector panes disappearing after I "Refresh", and I wonder if I could be somehow confusing the model or if this is not relevant.) also: Supposing this pattern is valid, is there an easy way to override the title of the view(s) added by otherObject? _______________________________________________ Moose-dev mailing list [hidden email] https://www.list.inf.unibe.ch/listinfo/moose-dev |

Should not be relevant. But there can always be a bug. If you find a reproducible case that would help. Also when reusing presentations like above it's better to define the #display block like this 'display: [ self computeValuesToDisplay ] ' instead of 'display: [ :each | each computeValuesToDisplay ]'.
If you return the actual presentation then you can customize any property of that presentation: gtInspectorFooIn: composite < ^ (otherObject gtInspectorFooIn: composite) title: 'Another title' Cheers, Andrei

Here is the part that I am missing: How do I tell the Inspector that the *value* to inspect is otherObject instead of self? I mean, it seems like this code constructs the GLMPresentation for otherObject but then applies it to self, which may not be compatible. Maybe I should add 'display: [ otherObject ]' ?
I have not finally tracked down this issue yet but it seems to be related to error cases e.g. pressing "Abandon" in the debugger. Symptom is that the first pane of the inspector mysteriously disappears. I will open an issue when I know how to reproduce it. _______________________________________________ Moose-dev mailing list [hidden email] https://www.list.inf.unibe.ch/listinfo/moose-dev |

Hi,
The way you make presentations reusable in other contexts id by making gtInspectorFooIn: display self. Something like this SomeOtherClass>>#gtInspectorFooIn: ccomposite <gtInspectorPresentationOrder: 5> composite text display: [ :ignoredObject | self … ] … So, the display block depends on self and not on the object you get in the block. Like this, when you do: SomeClass>>gtInspectorFooIn: composite <gtInspectorPresentationOrder: 5>otherObject gtInspectorFooIn: composite You will actually apply the inner presentation on otherObject (instance of SomeOtherClass), rather than on the current object (instance of SomeClass). Does it make sense?

Thanks (belatedly) for this tip, Doru. I have a follow on question. Is there an easy way to have the GTInspector include _all_ views for a sub-object? Like, I have a wrapped object that is a proxy to the real object, and when I inspect the wrapper I would like to automatically see all the views for the real object? Just now I am going into Raw and selecting the real object but this is a bit laborious. I also want to be able to disable the Raw tab for users who are not Smalltalk hackers.

Hi,
The way to do that is by overriding gtInspectorPresentationsIn:inContext: like this: SomeClass>>gtInspectorPresentationsIn: composite inContext: aGTInspector super gtInspectorPresentationsIn: composite inContext: aGTInspector. otherObject gtInspectorPresentationsIn: composite inContext: aGTInspector Cheers, Doru > On Dec 8, 2017, at 10:49 AM, Luke Gorrie <[hidden email]> wrote: > > Thanks (belatedly) for this tip, Doru. > > I have a follow on question.
