What is GTInspector using to print UUID?

Hi,

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.

Can this be changed?

Thanks,

Peter

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) ;)

Re: [Moose-dev] What is GTInspector using to print UUID?

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
