Hi
I have found a solution to my problem.
If you send the message allMorphs to a morph it returns a collection
containing all morphs in the composite morph including the receiver.
In this case a PluggableTextMorph would give:
aPluggableTextMorph allMorphs>> an OrderedCollection(a RectangleMorph(1207)
a RectangleMorph(3700) a RectangleMorph(1462) an ImageMorph(2630) a
RectangleMorph(2661) an ImageMorph(3061) a RectangleMorph(299) an
ImageMorph(464) a RectangleMorph(1782) a ScrollBar(1419) a
TextMorphForEditView(2717) a TransformMorph(726) a PluggableTextMorph(127))
I had used submorphs at first but this confused me because it returned #(a
ScrollBar(1109) a TransformMorph(2472)). But then I found allMorphs which
worked.
I had thought that the PluggableTextMorph contained a TextMorph as a
submorph since it had an instance variable of that name but it turns out
that it is a TextMorphForEditView which I found after browsing the
PluggableTextMorph class. So knowing that TextMorphForEditView inherits
from TextMorph I knew I could play about with the margins and other layout
properties of TextMorphs. But how to get to the TextMorphForEditView? The
instance method in Morph held a clue
allMorphs
"Return a collection containing all morphs in this composite morph
(including the receiver)."
| all |
all _ OrderedCollection new: 100.
self allMorphsDo: [: m | all add: m].
^ all
The message allMorphsDo: aBlock was the answer!
My solution is..
| aPluggableTextMorph |
aPluggableTextMorph allMorphsDo:[:each | (each isKindOf:
TextMorphForEditView)
ifTrue:[ each margins:

This works well but is it the best way to access submorphs?
Thanks

Subject: [Newbies] PluggableTextMorph
Hi
I'm looking for some advice on setting the margins in a
PluggableTextMorph(PTM) programaticaly. It can be done easily once the PTM
is open in the World by drilling down to the TextMorph and invoking its menu
using the halos, but I would like the option of initialising them, or adding
as an item to a menu of the PTM.
Am I missing something obvious? Should I just use a TextMorph instead? Hints
rather than solutions would be preferable.
Thanks
