I see two solutions :
one is to make two new classes :
PluggableTextMorphWithMargins that is a subclass of PluggableTextMorph
TextMorphForEditViewWithMargins that is a subclass of TextMorphForEditView
and one method in each new subclass :
PluggableTextMorphWithMargins>>textMorphClass
"Answer the class used to create the receiver's textMorph"
^ TextMorphForEditViewWithMargins
TextMorphForEditViewWithMargins>>initialize
super initialize.
self margins: [EMAIL PROTECTED]
And now you can use PluggableTextMorphWithMargins instead of PluggableTextMorph.
another solution is two send 'ptm textMorph margins: [EMAIL PROTECTED]' to your
PluggableTextMorph instance (ptm) from
PluggableTextMorph instance owner (in your GUI class initialize instance method
for example).
I think this is a better way ('one particular need, one subclass' is often not
a good scheme...)
