spec and double click

I have a ListComposableModel rendered with spec that I want to do something if an element is double clicked.

How do I register the event handler? I know about on:send:to but what Announcement do I use? In my testing with just a symbol #doubleClick it doesn't work (and probably isn't supposed to).

thanks,
Lo

for double clicked I do not know.
Did you check the when* API of ListComposableModel?

when:send:to:

In which Pharo version are you?

Yes, the closest thing might be whenSelectionChanged but nothing regarding click events as I see it.

In my ComposableModel the ListComposable model is 'attributes' so I did in initializeWidgets:

attributes when: #doubleClick send: #onDoubleClick to: self.

where the method logs to the transcript. But nothing shows up on a double click.

I suspect that spec has to setup the morphs it creates for handling (double)clicks and maybe it doesn't?

I strongly suggest to use 30 because spec changed a lot.

Doesn't seem to work either (on yesterdays 30):

| m |
m := ListModel new items: #(a b c).
m when: #doubleClick send: #traceCr to: Transcript.
m on: #doubleClick send: #traceCr to: Transcript.
"need doubleclick announcement?"
m openWithSpec

Maybe there's some spec mechanism for adding the EventHandler stuff
to the morphs it creates?

Re: spec and double click

m := NewListModel new

m doubleClickAction: [ self halt ]

m openWithSpec

This should work

your code and the following (double clicking the list items) doesn't work for me in Pharo3.0
Latest update: #30591

m := NewListModel new items: #(a b c).
m doubleClickAction: [ Transcript traceCr: 'foo' ].
m openWithSpec

Re: spec and double click

I will have a look tomorrow :)

If you are in a hurry, I know such a behaviour is present in EyeInspector

Thanks. I found handlesDoubleClick: true there and it works now
