Hi,

More specifically, you can find this specific extension here:

SequenceableCollection>>gtInspectorItemsIn: composite ^ composite table title: 'Items'; display: [ :aCollection | [(1 to: self size) collect: [ :index | index -> (self at: index) ]] on:Error do:[#()]]; beMultiple; searchOn: [:text :each | Smalltalk compiler evaluate: ' | entity each | each := self. entity := each.', text for: each value logged: false]; column: 'Index' evaluated: [ :assoc | assoc key asString ] width: 50; column: 'Item' evaluated: [ :assoc | GTObjectPrinter new asTruncatedTextFrom: assoc value ]; send: [ :result | result isNil ifTrue: [ nil ] ifFalse: [ result value size = 1 ifTrue: [result anyOne value] ifFalse: [self species withAll: (result collect: [:each | each value])]]]; showOnly: 50; helpMessage: 'Quick selection field. Given your INPUT, it executes: self select: [:each | INPUT ]'.

And then:

GTObjectPrinter>>asTruncatedTextFrom: anObject ^ [ Text fromString: (anObject gtDisplayString replaceAll: String cr with: String space) ] on: Error do: [ Text string: 'error printing' attribute: TextColor red ]

So, in the end, you want to override gtDisplayOn: in your class.

Cheers, Doru

Hi Peter,

It's done as a GT extension: see #gtInspectorItemsIn: in class SequencableCollection and (as nothing is carved in stone in Pharo) for sure this can be changed (or overwritten) ;)

how inspector decides what to print in the table/headings/etc? Because for UUID it prints the bytes (I guess because it's child of ByteArray?), however that's rarely useful for UUID, as normally you want to see the #asString representation.
