Hi Henrik,
thanks for the hint. (I think that the code snippet misses the
definition of the "example" variable).
Unfortunately the "problem" is located in the "Morphic Side" of the
"FastTableModel" class.
Specifically the "FastTableModel" class relies on the
"MorphicFastTableAdapter" which in turn (surprisingly) uses the
"FTPluggableIconListMorphAdaptor", and not the "FTTableMorph" as I would
expect.
The announcer for the "double click" is coded in the
"FTPluggableIconListMorphAdaptor>>initializeSelections", by the
announcement "FTStrongSelectionChanged", as follow:
---------------------
initializeSelections
self
onAnnouncement: FTSelectionChanged
send: #selectionChanged:
to: self.
self
onAnnouncement: FTStrongSelectionChanged
send: #strongSelectionChanged:
to: self.
---------------------
In my case "PictureListModel" is a subclass of "FastTableModel" and it
has been connected to a "FTTableMorph" object (through the
"MorphicPictureListAdapter") and NOT to a
"FTPluggableIconListMorphAdaptor" one.
In this way the "double click" has been lost.
I've wanted to avoid the "FTPluggableIconListMorphAdaptor" because it
seems a bridge for legacy code, as reported in a previous post, see
http://forum.world.st/Spec-Setting-rows-height-of-a-pictures-list-tp4920861p4922263.html.
Cheers,
Matteo
