Hi all,

The goodie enhances the "Senders of " functionality. It properly discriminates and selects the selector (no false matches as the ones resulting from the simple search currently used) and, if the selector is a multiple keyword selector, it also shows a multiple selection for all the keywords in the selector. It also allows you to iterate through the multiple sends of the same selector in a method body (if there are any) by simply re-selecting the same method in the list. (similar to VisualAge's behaviour, except that in VisualAge as well as in many other tools the selection part is also broken).

The implementation consists of:

- two new classes: PluggableTextViewOfMany and PluggableTextControllerOfMany - that could probably be used for other multiple-selection text activities as well

- two additional methods: #findSelector: in StringHolder and #signalReselection in ListController

- a small hack in MessageSet class>>open:name:

- and a small change in ListController>>redButtonActivity. Note that the change in ListController>>redButtonActivity means that re-selecting does not deselect anymore, which might be an inconvenience if you are used to it. But there is a bug anyway in that method (see further explanation). It also looks like the autoDeselect feature in PluggableListView is broken (I am not using it but I tried it with the only non-morphic sender of #autoDeselect: (which is FileList), and it does not work).

Anyway, if anybody is interested, please let me know where and how to put the files.

Now the bugs:

1. In ListController>>redButtonActivity

nextSelection ~~ nil & (nextSelection = oldSelection ifTrue: [noSelectionMovement] ifFalse: [true])

always evaluates to true, so

[self changeModelSelection: nextSelection]

is always executed, no matter what is in the variable noSelectionMovement. Now if we change the code to be...

noSelectionMovement ifFalse: [self changeModelSelection: nextSelection]

....we are using the variable but autoDeselect does not work anymore. This is actually what I did:

noSelectionMovement ifTrue: [self signalReselection] ifFalse: [self changeModelSelection: nextSelection].

2. In ParseNode>>printCommentOn:indent: there is a trailing line comment := nil.

I don't understand what could be the reason for that, but it certainly makes the comment nil in all the MethodNodes that you inspect. ;-)

Cheers,

Florin
