Hi !
First, I apologyse for the wall of text.
I'm trying my hands at Spec and I have few questions:
- How can I implement an instance-dependent layout ?
Regarding the layout method lookup, the documentation states that it
"starts on instance side, which allows a UI to have a more specific layout
depending on the state of the instance"
I tried to simply put a layout in an instance method with the *<spec:
#default>* pragma. But not only was it not retrieved by
*ComposableModel>#defaultSpecSelector* but
*ComposableModel>#retrieveSpec:*will send the selector on the class
anyway.
What I ended up doing was overiding #openWithSpec (which worked) but I'm
pretty sure that my model is not composable at all.
- Is it possible to change the "skin" of the basic widget ?
I would like to implement some sort of toggle button by changing the color
of ButtonModel and so far, I failed. I was not able to trace my color
change up to the PluggableButtonMorph because it seems to use anoucement
and I'm a Smalltalk rookie.
I tried however to send #color: directly to the morph which does nothing:
the #changed method rolls it back to its previous value. So I may be doing
something wrong but it doesn't feel like the issue comes from Spec. Any
clue ?
- On a side note, I tried to send an argument to the selector that
retrieve a widget in the layout method.
And I came up with this :
layout *add:* {#buttonAt: . 1}; *add:* {#buttonAt: . 2}; *add:* {#buttonAt:
. 3}
Is it how it's done ?
Thanks in advance !
Thomas.
